i need help..i messed around with my vtec contoller and now my car wont run correctly. the more gas i give the more the car wants to stall. I was wondering if anyone can help me with the correct settings, if they can be posted, idk if its different for each car, or if its even possible without going somewhere to be tuned. I have a 99 civic si turbo with an apexi VAFC II vtec air flow controller

Hmm, I think your best bet would be to reset the controller, correct me if i'm wrong. But depending who tuned it, you never know what variables were implemented.

It is different for each car, and you should definitely go somewhere to have it properly dyno-tuned.

 

1. disconnect vafc
2. throw it away
3. get a real ems
4. get it tuned by a pro

 

now your saying your car does run, wtf?
Sounds like your getting to much fuel try leaning it out slowly and see what goes on. Do you have bigger injectors? This is your third post and your still not giving us enough info.

 

they are stock injectors

 

why are you using stock injectors with a turbo? please learn what you are doing before you blow your engine.
