true...lol i belive that u can set the rpm level of when the vtec kicks in, worth 200 somtin online....i say yea sure

i think thats all it does is control the rpm level vtec kicks in

 

I don't think they are worth your money...

there really is no reason to change your VTEC engagement point...Honda matched up the curves pretty well, it's supposed to be a seameless cross over to the VTEC lobes...

Wrong.

The fields VTEC controller allows you to change only the VTEC engagement point, which on a stock cam is worthless because the optimum vtec engagement point is already programmed into the ECU. If you have an aftermarket cam(s) like me, then you will probably need to have the VTEC engagement point adjusted.

The Apex'i VAFC lets you to change the VTEC crossover point AS WELL AS add and subtract fuel throughout the entire RPM curve. It is a less expensive alternative to Hondata and is a lot easier to tune.

On stock motors, I have seen VAFC's add 5-20 HP in the midrange. It is a good tuning tool to have. However, unless you have access to a dyno and a wideband, they are quite useless.

 

if you're modifying cams and other parts that the factory ecu does not cover, a vtec controller would be mandatory. especially the air/fuel controller that comes with it.

 

The VAFC2 is a great unit, and you can find them cheap.

 

I agree with Bauley, you can do some minor but helpfull tuning with it and it has some pretty neat features too.
