VAFC tuning question?
ok, I was tuning out my VAFC with the EGT probe and WB 02 meter, and I was lowering my Vtec engagement point to 4700. On the VAFC there are 2 Vtec "icons" VTi and VTo. When everything was set to 0 and nothing on the VAFC was changed, the stock engagement point was 5000, and VTi AND VTo would light up as soon as it hit 5000. Well, when I lowered it to 4700, the VTi would light up as "ON" but it didn't sound or pull right, then when it got to 5000 the VTo would light up "ON" and it would pull like it was supposed to. Is there something I'm not setting right, is this where the vtec correction factor comes into play?? It was set at 0% for L->H and 0 H->L????

Yes, thats what thati s for. Increase fuel delivery when vtec activates and increase the L->H. If your vtec disengage is below normal vtec activation use it too.
uhm....do what?? I'm lowering the engagement point by 400 rpms, what is the correction % I should put into the VAFC to get the car to hit VTEC right?? I take it I should lower the percentage to a -6% or so, but I wanted some opinions about this first.
