Re: vtec controller (hondasport89)
One day i was searching and ran into a Apexi write up on it of how it works and all the ways it plays with the sensor. sorry i couldn't find it again i knew i should of bookmarked it.
from what i have heard people say they are okay i yet have to install mine.

They pretty much don't. They adjust when vtec engages, the problem is twofold, forst off those honda engineers are pretty smart, vtec engages where it does for a reason, and the vast majority of the time moving the engagement point will cause you to loose power. The second point is all the vtec controller can change is when the vtec solenoid engages the second cam profile, the fuel and timing maps remain unchanged.

truth!
Don't play with a vtec controller, thats fail!
Don't get a vafc hack either, you cant tune with that crap on hondas.
if you have internal mods, then you just need to visit a dyno and get a real tune.

Right, unless the engine is heavily modified. Major head porting, increased displacement and compression and especially wildly different cam profiles etc. may nesessitate the need for a controller so that the VTEC engagement point can be set at the optimal rpm, be it later or sooner than the stock engagement point.
This is the original purpose for a VTEC controller, not really intended for a bone stock engine.
A good example is that most VTEC engines have different engagement points.
