I agree that it's not totally a waste of money. If you have lots of mods already, then forget the VAFC, save for a proper aftermarket tunable ECU. If you just have I/H/E and are looking at adjusting vtec/air/fuel (as said above) then go for it. It's fairly cheap and will do the above.

BUT, do not get this just because it can adjust the VTEC crossover point. So many guys buy VAFC's purely to bring VTEC in earlier. It does NOT deliver more power and IMO only makes a shitload more noise earlier in the RPM range. In fact, there are a few guys in Melbourne that have had their cars dyno'ed with VAFC adjustments (set to 4000rpm etc) and have lost power. Coolies on this forum had a piggyback unit (yes it wasn't a VAFC) but it had VTEC set lower than the standard VTEC point and he was being robbed of power. Just ask him and pornstar!

Bottomline what everyone is saying, don't get this for the rice factor. There are better ways to spend money on making the car go faster!
