hey guys i wanted to know what the difference between partial throttle tuning and WOT tuning. i kinda of have an idea but want to know which one requires to reset the ecu every week so the tune wont get lost. i want to completely avoid that tune. also anyone have dyno numbers on how much power they have made on a stock s2000 with a vafc tune. thanks!

I do know that a VAFC is only good for WOT tuning, since the partial tuning will be lost and reset. Go check out the Naturally Aspirated section, or search VAFC dyno. There are tons of people that have dyno's with their VAFC's. Just so you know, a VAFC is not going to make a big difference if your car is stock. It gives good gains if you have bolt ons (i.e. Header, exhaust, TP, intake, ect) So maybe you should look into doing a few bolt on mods before the VAFC.

You will probably get alot more info from the NA and FI forums on tuning.
