so with this chip i wouldn't need to get a vafc or fmu or something like that right, does anyone have expierience with these?

never buy a pre-chipped ecu for your car. Alot of things need to be taken into consideration before changing fuel maps

moving this to the ecu forum.

 

From what I understand, dont you send your whole ecu to Hondata or something like that for them to tune?

 

No you tune it on a dyno with the compatable windows software provided. Same with uberdata and ems. Now i do suggest a good street tune also because when tuning on a dyno you tune for wide open throttle. it is very important that you tune for part throttle because that is where your car will spend most of it's life.

 

so what you mean by a street tune is without a dyno, with and a/f ratio gauge and a laptop or whatever is needed to tune your management system, right?

 

not an air fuel ratio gauge, you need a wideband o2 sensor. Air fuel gauges are narrorbands and will not give u a good enough reading for proper tuning.

 

This is true.

You can tune on a dyno at wide open throttle all day long and get everything perfect on the dyno but that will mean nothing in stop and go traffic, with higher and lower ambient air temps, and at part throttle. Not saying if you only dyno tune it will blow in normal driving but I am saying it will not run nearly as good as it should, may overheat, be bad on gas(who can afford that now days).

I allways street tuned before I hit the dyno.

 

so is there any posts on how to tune at part throttle, and would you tune at like 50% or something, just how would you tune at part throttle, because i understand alnost at wot

 

You do need a lap top to tune it. And a program like hondata, crome, uberdata. I know a guy who builds custom turbo kits and just looks on the internet at other ecu's maps that are tuned for boost, uses that, then he makes minor adjustments here and there because every engine is going to be different. You can order a pre-chipped ecu but it's only good if you have a program to tune it with and someone with experience.

 

so where can you find these that are already tuned for boost?
