ECU Tuning & Fuel Management - eBay ECU Chip Information

Ok to the point i am tired of seeing the whole ebay chip thing gone over and over and over.

For one thing a 96+ honda ecu can not be chipped, simple as that.

Ok now that's out of the way I will keep this short. A ebay chip reprograms the air/fuel maps on a stock obd1 ecu. Sounds good right? NO. You never tune air/fuel tables on a wim without the correct methods to chart what you are doing or have done to your car. What people fail to realize is that other than the "chips" leaning the hell out of your a/f ratios which is not good unless you have the supporting mods to handle and keep track of it, they never alter timing. So your running around lean as hell on stock timing on a engine that was made to get the best fuel economy it can. You start getting pinging or knock, but your great new little chip is fooling your knock sensor to think that it is not so the stock function of the ecu/knock sensor which will compensate and advance/retard timing to make up for your lean condition is not doing it's job. This makes it so there is no safe mode on your ecu, no safe mode = engine blowing the first time you

1. Get Bad Gas
2. Pre-Detenate enough to blow a hole through the piston(which is alot more often than you think) People would be shocked because about 95% of honda's if you were to pull trouble codes from the ecu you would pick up on atleast 1 cyl mis-fire in the past week. And that is even when it never throws a CEL.

It simply aint a good idea, you still have to get your ecu socketed to accept the chip and it hardly cost anything to have somebody burn a uberdata or crome chip for your application and still retain factory sensors ability to keep the engine together. Honda knows what they are doing with their ecu's, they for the most part are pulling as much power as they can in stock or near stock form and that is why you dont see much gain with bolt ons......once again for the most part.

All EBAY CHIP threads for now on will be closed and I will put a link to this in it. If anyone chooses to talk about them do it here.

good knowledge right there.

and if you need more info on chipping an obd1 honda ecu...pm, me....or whatever other method of communication you choose. There is a reason to chip an ecu and that reson is not to add 20whp to a bone stock motor. That just doesn't happen. And if it does...the engine lasts 10 minutes or less. So let's read up and do it when necessary and the right way the first time, shall we?

Yea if you have ever heard that a engine runs it's best right before it blows up it's cause more times than not it is running lean and while lean will make more power it will also heat the cyl up and make the fuel just burst into flames before the piston gets to the correct point and before the plug ignites it. This is called detonation

It's hard to find info on the acutal tuning process.

dyno or street tuning?

but wait.........i have a 97 dx 4dr bone stock under the hood..........i bought one of them ebay chips and it gave me vtec, even said it would give me vtec in the instructions. now my car pulls harder and you can actually hear vtec!! [8D]

dyno or street tuning?


Either. I'd love to see some good articles on it.

hey marty, i have an 03 lx with intake and exhaust, can i chip my ecu?

i kid i kid.

just to make things clear to anyone reading: post 1995 ECU's (again anything that is obd2) can not be chipped, and you need not worry about fuel management anyway if all you have is I/H/E. it's not worth it just yet.

ok i got one of those 8 dollar chips on ebay and their ****ing amazing i felt it immediatly. The thing is you only feel it in open throttle the car flies now. Its a wire that connects to the sensor, it pretty much absorbs more gas with air. Before i was doin like 325 miles on a tank, i do now like 300, but i guess its because i hit the gas harder now to feel the effects, but its worth it.

lol

nah, i know it works because first i timed it but also when u slam the gas the car just goes no hesitation which takes time.

I hope to god he is joking....

y that an 8 dollar thing works well

aaahhhhhhhhahahahaha. Good investment! :D

its not a chip, its an IAT mod, and youre even playing with fire with a simple little thing like that. it advances youre timing because it makes the car think the incoming air is cooler than it really is. you hads better hope its the right resistor, or on a hot day, or with a bad tank of gas, you could hurt your motor.

People do not understand that it is not good to trick your car into thinking one thing when it is not true.

Ive talked to 2 people who used those things... one of them had their motor catch on fire. :D

Its a 10cent resistor but you paid $8 for it.

^ yup. They are readily and always available @ radioshack.

its alright, i does a good job thats all i car about

You have one, soldout?

yea ilove it they work amazing read the like second post i put

No, it's not doing a good job, you just think it is. Seriously, unless you want to deal with serious consequences down the road, I suggest you take that thing out, ASAP!

im not supriced since its coming from the guy with a hood scoop

Why wont people pay top dollar for engine parts? Why save $300 on header when it is so important?! An $8 ecu... how stupid.

if you want info on tuning your ecu, www.pgmfi.org is the place. and don't just post a random newb question, actually search andread, and read, then read some more. then post your question.

so since no one will put it in simple terms.. its not a good thing to buy

NO!!

That's because you have an automatic.The only useful thing a chip will do to a car is reduce hesitation in autos.

Other than that, you DO NOT need to chip your car if you only have an I/H/E

However, if you have a turbo, low-comp pistons, stage III cams, full valvetrain, and nitrous, you will need to at least have it tuned if not chipped.

tuned.....chipped....difference? :eek:

Yea there is a difference. You can chip a ecu all you want with a chip that has a crap program on it and no that is not tuned

how do they chip a ecu or tune a ecu, by that what method do they use?

Thank you guys. You answered my question. don't do it. I ran across the ebay chips friday, and I was wondering if it was worth it.

97 Honda Civic

Hey, i had just recently purchased a chip for my civic (completely oblivious to anything) just lookin for a little more power.. it was similar to this one. http://cgi.ebay.com/ebaymotors/Honda-Civic-Accord-CRX-Element-Pilot-Performance-Chip_W0QQcmdZViewItemQQcategoryZ107070QQihZ009QQit emZ190107508643QQrdZ1..is this what all of you were talking about, these things?? its not just a resistor, but it does "fool" the car into thinking the air is cooler and it wires up to the IAT sensor... any comments would be helpful before i either install or re-sell this thing.. thanks!

your best bet is not to install it at all, but thats just me.

Hello Guy's Nice site.
(newbie) " I've read a little bit about this thread and i'm confused about the chip. When taking the car to a tunner is he not tricking the ECU regarding A/F mixture etc...? This is not a challenge to your knowledge just trying to understand the best possible route for my XSI. I want the most out of the B16 without boost or NOS.
Thanks in advance

no its not really tricking, more like telling your ECU to provide more fuel, adjusting the spark, and doing various other things.Its necesarry if you are boosting an engine so that you can provide enough fuel to match all the air coming into the engine. On a stock engine though it will not make much of a difference and the price you pay to have your car tuned wont be worht the gains.

how about that juice box? is that a chip? the company says its safe, and that it will correct any errors that other chips cause. check it out at thejuiceboxcompany.com. let me kno if its safe for my 96 civic ex coupe. please!

NO NO NO NO!!! I actually bought the stupid freakin' Juice Box crap and it fried my IAT sensor. Don't Don't Don't!!!!!

do u remember about how many miles u had the juice box on for when it fried your IAT sensor?

I had it on my car for 2 weeks before it threw a check engine light. DON'T

hey thanx for tha advice danomatic. im goin to take that junk off! b4 its too late.

Not to be funny....but I have a 98 Honda Civic Ex. .... I have had my Juice box for now 10 Months..... NO PROBLEM AT ALL! I have did LOTS of traveling and street racing on my stock engine.... no check light came on, no Engine BLOWN, no IAT sensor fried. YES, my car is a automatic but the box has perform well for me. But I don't advise no one to get it JUST because of my experience I had with the Juice Box.

Now after all that is said, AND after reading this topic fully. I may take everyone advice and take it off.

Is there any safe chip u can purchase than? i been reading thsi whole thing and u guys say that the ebay chips are bad, Juice box is back. getting ur stock engine tune is not worth the gain. so what the best thing u can do than? there has to be an safe chip u can purchase. is Hondata the only safe thing?

the real question is "is there anything actually worth it, that you can purchase." I'm sure there's a way to squeeze out more power out of a stock engine if you tune for let's say 93 octane. But you'll pay for engine management and the tune for may be a 10-20 horspower gain which at the end will be less cost effective than a whole turbo set-up. The cheapo "chips" and "magic boxes" don't really do anything. In fact my buddy and I have taken something called a "power-chip" apart and all we founf inside was a bunch of wires. Guess what, it was supposedly designed to increase throttle response...all it did was ground the head to the body really. You can do that with a grounding kit.

well my next question..... HAVE anybody did a separte dyno test.... One test with a box and one test without. If not, I can do it this comming weekend...

if you have money to waste - go ahead and do it :)

I have 5 different "chips" that I have allways wanted to send to someone to pull the maps off of just to see what is up with them.

ORIGINAL: Roto

if you have money to waste - go ahead and do it :)


I won't waste a dime....My Uncle owns a shop. And I already have a Juice Box....

ooooh.....than it's a whole different story...would you be willing to test three more things? Like an ebay SRI vs ebay CAI vs filter stuck on TB? You could be a great source for the community there...

whats wrong with an ebay CAI, are they bad for the engine. Im running a B16A2 with one fitted

Don't worry; they don't hurt the engine at all. It's just that they usually don't have as big of gains as name-brand intakes. You could stick an AEM or K&N filter on your ebay tube and see about the same gains as a name-brand system, though.

My room-mate did a fundraiser on his Triumph Speed triple forum to get money together to get good tunes made for some aftermarket exhaust/header combos. If we have a guy with a hookup on free dyno time for testing we could really get some useful research done!!!

I hope he wasn't just blowin smoke!

Sorry...but I don't smoke.... I do have a Uncle with a shop..... and This past week my D series was JUST turboed..... Go to the New Member forum to check it out. But Sunday, I just learned they took my Juice Box out because Now my car is turbo and no use will the chip be. BUT I must say after talking to Several Other people, they said the same thing y'all guys said..... CHIPS just DON'T do Dittlie.

i knew someone who chipped their Nissan Primera SRi and it did bugger all to his performance. It just made it more un-economical.

I want to chip my ecu, but I can't decide what flavor. Any suggestions? :D

im glad i came across this cuz i was gunna buy one haha[8D]but i guess not, haha thanks for the info

I want to chip my ecu, but I can't decide what flavor. Any suggestions? :D


is that a joke?

wow this would have been great to know. so i dont have a box or resistor. it was a 28 prong chip, 20 prong chip, jumper and a resistor i had to sodder to my ecu. you all saychips are bad but it said that the chip was tuned for my car with headers, exhaust and an intake which is what i have. it was cheap like 20 bucks shipped. the spots i put them in at were empty spots in my ecu. it deffinatlypulls alot harded i feel a big differance. how bad are these for my car. i got one that did not dissable my knock sensor cuz that sounded sketchy to me. it said it ajusts the fuel curv and timming curve for more power.

i'm going to go with boost, and therefor tuning is going to be a must. I am probably going to go hondata as opposed to just an ebay chip. i have heard nothing but good things about hondata products, but wanted to know if any is using their system, or if anyone has negative feedback on their ecu's.

I've got a 99EX D16 boosted. I'm running about 11psi on stock motor, tuned by me. I've done more research than I can handle, but I've learned a lot. I have read/heard nothing but good things about Hondata, except for the prices. I personally went with Crome. Not sure what car you have, but with mine I went with the OBD2 to OBD1 conversion harness, P28 chipped ecu.
I like Crome because it was free(& rev limiter, speed limiter, full throttle shifts, CEL shift light, launch control, boost cut)!!ha Will soon be upgrading to Crome Pro($150). Even with Crome free I can tune in real time, then when I get things where I like them I just burn 1 chip and install it and I'm done. With Crome Pro you can also datalog, which will make things MUCH easier and faster to tune properly. Although, if you don't know what your doing when tuning, I highly suggest getting it done by someone who does. One wrong number and KABOOM!!!!!!

lol are people comparing ****ty 20 dollarebay resistor chips and tuning softwares/ecu now?

ok i own an 97 ek4 with a d16y i just read your article on ecu chiping. i got my **** running bone stock. and i plan to throw in a b18. whats the best way to get my car runing clean as ****..

Wow thank u for this jus saved me 6 dollas and an engine lol

Hi all,i am new here and i just read the posts about the ecu chipping..I bought this already http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=160279821779&ssPageName=ADME:B:EOIBSA:MT:11 but now i am not sure if i am going to use it...I know that the real mods are cost a lot of money but i would like to ask if that one will make any damage to my car.Also, if not, it will do something good about the power of my car??
Thanks

Throw it in the garbage.

Throw it in the garbage.

Why is it so bad???

Not to be rude, but please read the first post of this sticky.

i read it already but i was think that it was talking about that resistor that you install on the engine bay on the air sensor.....So do you suggest that it is safer to have a full remapping of my OEM ECU?? BTW the car is an EG4 D15B SOCH VTEC engine..

jet says that they have a chip for a 2000 d16y7. ive always thought there was nothing u could do to an obdII. what do any of u think of this

don't buy that
the only thing you should even consider is a chipping kit for your ECU, but it has to be a legit one, such as the one sold by Phearable.net

as i understand it is a chipping kit for the ECU....I have to install one chip in the ECU and replace another one as the directions said...

yea, i see now what you're talking about

i just really don't think it's legit

i misunderstood what you said at first

Isn't it something similar with a VTEC control??
Or even a VTEC control is not legit??

Vtec controllers do what they are set out to do which is change the point vtec hits but you shouldn't do it without extensive mods(like cams mainly) and even after that you needto do it on a dyno to make sure it is getting set at the right point

what i mean by i don't think it's legit is it says it's tuned by JUN.
"JUN TUNED SOHC VTEC OBD1"
1. Never heard of JUN before, but I looked it up and it's in Japan. Well, the guy is selling these out of Ontario, Canada.
2. I don't think any real tuner would offer a basemap for sale designed to be used the way it is with no further tuning, without asking for your engine's specific details and such.
3. It's on eBay. Most chips on eBay are not legit.
4. There are many other chips on ebay that say they are Mugen chips, or Spoon chips, when in fact they aren't.
5. This chip says it changes the VTEC point to 5000, which is fine, but it says it raises the rev limiter to 9000. That is just stupid. 9000RPM on a stock D15B? You'll fry your engine in no time.
6. "Tested in a Civic with D15B SOHC VTEC, WOW! Pulls HARD, right to redline." sounds just like the anthem of the fake product on eBay.
7. Those Mugen chips I mentioned... well that seller on ebay has one of those too. And there's no doubt that it's not Mugen.

Thanks for the answer..I know that it is not a real JUN chip but i guess that it is based on that..Maybe they copy that program?? Also i don't care at the moment about the REV's limit because as you said it is a stock engine( at the moment :p)..I want just to have some more acceleration if it is possible and yes the lower VTEC point is something that i want too....Sorry for all those questions,i don't want to say that this chip is a good one but i am really confused with what is good and what is not....

lol, I like to number my points because it separates them well.
anyway,

1. Well, in all reality, this chip doesn't lower the VTEC point. In fact, it does just the opposite. VTEC Point on a D16Z6 is at 4800RPM. JDM D15B is pretty much a D16Z6 and I think it hits VTEC at the same point. This chip raises it to 5000RPM, which is actually a pretty good number. That's what Phearable set mine for.

2. You aren't going to get much power out of a chip anyway. If you're looking to gain a little power, do intake/header/exhaust/high-flow catalytic converter. You still won't notice much out of these bolt-ons though. There is no reason to chip your ECU right now with the way your car is. A chip would be good to squeeze the most potential out of bolt-ons, but you need to get the bolt ons first. I really recommend re-selling what you bought on eBay and getting the Phearable.net chipping kit after you get some bolt-ons, because it's $30 and you actually tell them your details on the order form and they make you a custom basemap. The Phearable chip actually adjusts your fuel maps too, which the other chip doesn't.

3. Lowering the VTEC point is stupid without doing it on a dyno. VTEC is basically having 2 different cam profiles, but on the same cam: One for low RPMs, one for high RPMs, with engagement point controlled by the ECU. Your low cam profile only works good at low RPMs, not high RPMs, and your high cam profile (VTEC lobes) only works good at high RPMs. In most cases, lowering the VTEC point actually reduces performance because of this.

Thanks again mate...The VTEC point in my car is about 5500 RPM if i am not wrong BTW....
You got a point on what you said and you are absolutely right.
I got one more question a little bit of topic..
When i used to have the same car,it used to have a AT-ECU with VTEC point at 5700 and RMP limit on 7700.I Tried a MT-ECU with VTEC point at 5500 and RPM limit on 7500(like the one i have know).I noticed that the AT one had much more acceleration than the MT one....It was faster,and it reached the VTEC point on 5700 much more faster than with the MT on 5500...Why that happened??I know that VTEC works better on High RPM but why whas that difference on lower RPM??

wait, you were using an AT ECU on a MT car?

wait, you were using an AT ECU on a MT car?

To be honest i am not sure about that...I bought an engine with the ECU to swap my 1.3L civic to D15B engined...When i installed it it worked great and one day the ECU was damaged....I searched to find the same ECU but it was impossible.Then i found an ECU from a crashed car D15B MT and i installed it.Then i noticed that the car wasn't so fast as it was before...the only explanation that i found is that the car i bought for the engine was an AT car with a MT gearbox...Or the ECU was chipped....Some local mechanics told me that the most reasonable explanation was that the ECU was for AT (I DON'T REMEMBER THE CODE BUT IT WAS A CHIP ON THE''AT-ECU'' THAT IT WASN'T ON THE ''MT-ECU'').Also a friend of mine used to have an AT SIR and he just swap the gearbox to a MT.And believe me this SIR was much more faster than other MT SIR....The explanation was that an AT car needs more ''power'' than MT and that's why a MT car with an AT ECU is faster than a MT car with a MT ECU...
And then i was totally :confused::confused: :)

1. i don't think you can chip an auto ECU
2. you would have thrown a CEL if you were using an auto ECU with a manual tranny

and the explanation the dude gave you is bogus

1. i don't think you can chip an auto ECU
2. you would have thrown a CEL if you were using an auto ECU with a manual tranny

and the explanation the dude gave you is bogus

So there are 2 explanations.
1)the ECU was AT
2)the ECU was a chipped MT
Do you have an explanation why the ''AT-ECU'' was faster than the OEM ECU??
Sorry for my acknowledgment but what is CEL??
BTW the cars/ECU where JDM if that's matters...

CEL = Check Engine Light

There's no way it was an AT ECU, because it would of threw the CEL.
Which leads me to believe it was chipped, and perhaps it had more altered attributes in the chipped program than just rev limit and VTEC point, which would explain more performance. There really shouldn't have been a big difference in performance though, maybe slightly noticeable but not so easily apparent.

If you really want to chip it though, I really suggest the Phearable chip kit. I got one and I noticed a small difference. The main reason I recommend this kit is because Phearable is really good at tuning - they know what they're doing. Also, they actually alter your fuel maps to be more aggressive. I would leave the VTEC point and rev limit fields in the order form blank though, they will change it to what they think is best, which I trust their judgement with because they're good, and they are the tuners after all. They make their basemaps based on what they have seen work for that type of application while dyno tuning.

Honestly i don't know how to thank you....But what is the point to set a higher VTEC point than the stock one??Is that because of the fuel map setting??
Also does Phearable could send in Cyprus(europe)??

I guess they determined that was optimal.

It sounds normal though, my stock VTEC point is 4800, and Phearable changed it to 5000RPM

here's a link to the JDM chipping kit. I was mistaken, it costs $40 for the JDM kit. I guess for the JDM one you don't put in your own info, they'll figure it out I guess.

yea, they ship to cyprus

Thanks once again mate.....I already sent them an email and i hope they will answer to me soon and i hope the can post worldwide :)
Thanks again for everything mate!!!!!I will let you know what happened...

no problem
good luck on the install
be careful with the soldering, don't let the actual board get too hot

i will take it to a professional to do it :p

I TRIED IT AND IT WORKS AT THE MOMENT.....i noticed a noticeable difference on acceleration,especially on the VTEC zone...I don't know if it is going to damage anything in the future,but until now everything it is OK....The engine is a JDM D15B and i have only an high flow air filter and nothing else....I guess the ''program' gives a better mixture with more fuel,air etc,so i guess it will be better when i will change the exhaust system,the inlet etc....NO BAD FOR ITS PRICE....

Is the chip made for a I/H/E setup? If so, I'd suggest getting an exhaust to help take advantage of your new fuel maps and really help your car breathe better.

you bought it on ebay?

its all in your head....

Yes i bought it on ebay...It is a chipping kit for the ECU (ROM) with a Jun program in it....Why you say that it is all in my head??For that reason to be sure that it is not in my head,i gave it to a couple of friends to drive it without telling them anything about chipping my ECU and they asked me why the car feels faster than before and what i have done to it...I have an extra OEM ECU and i made a test drive with both of them,and YES THERE IS A DIFFERENCE...I don't say that it is the best thing,or that it makes a huge improvement but only that it makes a noticeable difference,which IMO it is good enough for a standard car's engine and for its price....And it is not necessary for everyone to believe me,i just tried something and i would like to post the results....
Can you please explain me why do you thing that its all in my mind??Because i am really confused on that and i really want to know what it is going on with chipping the ECU...
Generally and logically speaking,giving a richer mixture to the engine,it will be faster i think...If not,why then people change ECUS or remapping them?? I know that the program of that chip it is not adjusted exactly for my car's setting but for D15B engines in general,and it is better to remap an ECU according to the car's specs but believe me i know when my car it is slower or faster....

you bought it on ebay?

Yes mate....I bought it on EBAY and it is supposed to be a JUN program in the chip,similar with other chip with a Mugen program....I know that those are not original Mugen or Jun chip but i guess it is a copy of their settings,or they just use the name of those companies....

incorrect

timing, and to make the a/f ratio stoic

they probably just used the name JUN in the listing to get search results
ebay is a shady place

BTW for those that they didn't read before is that chipping kit

My mistake then mate....I thought that by remapping an ECU you give a richer mixture at the time that the car needs it...
Just to understand it a little bit more,what is this ''JUN'' chip supposed to do???What is the difference of remapping a stock ECU(except of the different parameter of course)??
I am totally confused to be honest with all those things :D
I know that they use the name of Jun,Mugen, Spoon etc just for marketing reasons....
BTW thanks for answering to me,maybe those questions seem stupid but i really want to know what it is really going on...
Thanks again....

a/f ratio is the air/fuel ratio right???

any chip company that would put a D series rev limit at 9000RPM and is designed for a stock motor is obviously selling fake chips or has no idea what they are doing. you can't rev a stock D-series to 9000RPM without messing something up. and if it doesn't mess up the first time you do it, it will soon.

it's probably making the engine run a little leaner and making the timing a little advanced. because of this you are suppose to use 91+ octane (in USA methods, not sure about your country).

I know that 9000 are too much for a stock D engine mat,thats why i will never take up to there...I use it up to 7800-8000 MAX that i know it is safe for a stock engine because of the previous EG4 that i used to have :D
In Cyprus we have only 95,98 AND 100 Octane fuel....Which one do you think it will be better to use with this chip??At the moment i use always 95 octane on both of my cars(the other one is a TSX 2.0L i-VTEC)...Do you think that 98 octane will do any difference or it doesn't worth the difference on price??
Thanks again mate....

get 98 octane
i know that your 100 is equal to our 95 (which we don't have, but this is a theoretical number), so your 98 is probably equal to our 93. I would use that. I run 93 in mine for my Phearable chip (we don't have 91) and I have no firing problems at all. My dad put 89 in mine once and boy did that run like crap. It was misfiring all over the place. IMO it's worth the difference because the higher octane makes the engine run buttery smooth because of the timing parameters in our basemaps.

Thanks mate,i will try it ASAP....

Hey guys i know ebay chips are usually not any good and will do damage, but how is this one?
It doesn't look like it's just some crappy little resistor.

You might as well throw some money into a the toilet and flush.

Haha whats wrong with it??

it looks like some one made it in there basement out of a mint candy tin. its not evan hooked up in those pictures. it wouldn't be very smart to hook that up to your car.

Come on man, listen to this, because it's all you need to know:


If it's a chip or electronic "performance module" on eBay, and it's not something name brand like the AEM EMS or GReddy E-manage, it's a hunk of junk tricking you into thinking it works. There are chips on eBay that call themselves "Jun", "Mugen", etc. chips. Those aren't really made by those companies.

And none of these so-called performance modules work.

Rule #1 of eBay: If you want to buy a chip, don't buy it on eBay, buy it directly from the tuning company.

If your looking for easy way to make your car quicker go with a set of better tires. That way you can dump the clutch at a higher rpm without spinnig, and you'll be able to hold some speed around a corner. You'll be faster doing that than buying a cheap chip.
