My basemap runs fine... probably because i don't have turbo, so it's easier for them to make me a better basemap

 

Ya, i shouldn't say that they make horrible basemaps, but in my case it was horrible and I wouldn't reccomend running any turbo'd car off their basemaps!

 

I believe that was the reasoning behind the k20a2's vtec point.

Besides that, I believe vtec is set to where the torque and horsepower lines cross on the dyno graph.

And bc, you have to remember, it was a basemap they made you. A basemap is just what you run to avoid blowing your engine before getting it tuned after boosting. The safest thing to do with basemaps is to run full-rich; it kills power, but you won't lean out and blow the engine.

 

Do you understand what a basemap is? it's purpose?

It's setup so that when you start up your turbo car, it runs rich so you don't blow your motor as soon as it starts up. It's meant to limp you to the dyno/tuner to get a proper tune to make the proper amount of power you can with your setup.

THIS IS A BASEMAP!! don't be stupid and run your turbo setup with a stock ECU. i wouldn't even put in a new camshaft into my NA civic without a proper tune. Stock ECU only has such a range in parameters that it can adjust based on sensor data. Unless you are putting out low boost, get a proper ECU tune/Setup.

 

Vtec engagement should be set by running the car on a dyno with no vtec engagement throughout the rev range, then run it with the vtec engaged completely and do another run. Then put the graphs together and find the point where the power crosses on both graphs so that the low rpm power of the non vtec lobes can motivate the car from a standing start, and the vtec lobes can suck in more air for high rpm power. thereby eliminating any kind of drop off or hiccup in power.

It's easier to explain with a graph in front of you.

 

^ yeah, I knew it was two lines crossing on a dyno chart, I just couldn't remember what the lines were... for some reason I was thinking hp/tq

but I beat you to the basemap thing lol

 

Stock ECU? Have you read the full post? Why would I be putting out low boost on a basemap tune? I'm not dumb enough to be running boost on an engine that hasn't been broken in or tuned yet. I know exactly what a basemap is for and I know that they're supposed to be slightly rich, I drove the car about a mile to get it home but I had to pull it over once. It's not supposed to blow blue smoke, make the car idle at 3000rpm going up and down by 300rpm, and give properties of vacuum leaks. Why would it have made my vacuum go to 5 HG and I didnt even drive it over 30km/h because it hardly ran. Thats idling almost in boost, I've researched this stuff for a long time so dont tell me im being stupid. Speedtech told me if I would have drove it anymore with the basemap it could have caused severe engine damage, something to do with the pistons I believe. My old ECU I ended up putting in is a chipped P08 and was tuned with Uberdata for my turbo setup with a 14b before I upgraded to the 16g Evo3 and got the engine built. When I put in the chipped P08 the car actually idled very well for not being tuned and it was actually driveable. The car is currently parked and I'm getting it tuned with my old ECU unless my tuner can make a new basemap for my Phearable chipped p28. I'm getting a basemap tuned with a wideband air/fuel gauge to break in the engine for 500k before I get it on the dyno for full tuning and dyno runs.

 

If your saying that my vtec is supposed to kick in at 5k then there is something wrong because mine kicks in at 5500-5600rpms.

Ok so Honda puts the vtec at a certain rpm, my only problem is that from 4k-5500 its slow. I am just wondering if I SHOULD buy a vafc to lower my vtec?

sorry I posted then missed some replies in there. I will do better.

 

No.

and how do you know where it's engaging VTEC anyway? what is your method of telling where VTEC engages?

 

The seat of the pants dyno. It feels like a turbo when it kicks in at 5500. Is it actually kicking in sooner? As I said from 4k to 5500 its like comon comon comon BAM.
