- Wed Jun 10, 2009 1:13 pm #121915 i hope this is in the right section. i just bought this car about 3 weeks ago, so i'm trying to figure out everything about it that i can. it is a turbo b16, and it has vafc2 on it. my question is, when i'm stopped i push the clutch in and rev the motor all the way it only goes to about 4500 rpms and acts like it has a two-step or some kind of launch control.it runs and drives fine, it only does this stopped. is this a function of the vafc or is it something else because on the p28 ecu it has a phearable.net sticker and an ungodly amount of wiring splices. i looked on phearable.net and they mostly tune w/ crome or hondata. how can i tell if my car is running crome also, or if it was only tuned on the vafc. thanks. chris

- Wed Jun 10, 2009 3:06 pm #121958 if you open up the ecu and in the lower left corner there is a chip, then its been chipped, If there's just open solder points in the lower left corner then its not been chipped.

If You have a chipped ecu there is no good reason to use a VAFC as well. If there has been something else done to the engine, i.e. Boost, Came, etc then get it retuned by a local tuner.

And I believe the VAFC2 will give options for launch control, as is possible with a chipped ecu.

I'd consider selling it and repairing your harness and going with a reliable chipped ecu (hondata, aem) if you have the money. Or even ectune , neptune, chrome if you're on a budget.
You'll have a much more reliable and safe setup
