I've had my VAFC tuned but I think that my stock ECU has overridden its control. I need to know what to set to 0 so that it will only be controlling A/F mixture at WOT or 40% + throttle. If it were an SAFC I'd know more about it but this thing has a lot more control than an SAFC IMO. Thanks.

 

In your VAFC you need to set it to WOT only.

Narrow 0%, Wide 99%


no reset your ECU and you are back to making power!!!

 

thats it? lol. thought it would be more complicated. Ah stupidity is bliss

 

Does the VTC do anything in an S2000?

 

bump

 

Yeah, there are people who have had success with them, especially in the midrange where all tunes seem to work well for the S2000. Check out the 230whp NA thread (in this JDM section) for some different #s though. Oh and if you get one, make sure you get a good tuner for the car, V-AFCs can be dangerous in the hands of a novice.

 

yeah gonna re-tune it and if I cant break 200whp on the dyno dynamics im gonna sell it and get the HKS fcon iS.

 

ya I have the VAFC2 and I was told I need to reset my ecu once a week

 

If you did a partial thorttle tune, if you did only WOT tune then you don't have to reset your computer !

 

I want partial throttle tune so I can use more power when Im not just racing
