My buddies girlfriend recently purchased a 2001 Honda S2000 with 40,000 miles and the F20. It has an Injen intake and a HKS dual catback exhaust. It also has an Apex i Vafc 1. Does anybody know what are good settings with this little mods done to it. I know that Vafcs are generally only for fine dyno tuning with a modded car, but they just wanted me to post up and see if anyone knew a worthwhile setting.

 

There isn't a set good setting. Every motor responds different regardless if it's the same model. Best thing to do is get it tuned on the track/dyno.

 

Agreed. That would be assuming that you have the mods to need an air-fuel controller. Intake and exhaust are just basic bolt ons and don't require any extra fuel. I would take the VAFC off and let the stock ECU handle fueling for maximum efficiency at this point in time.
