Well if it was done that way, he still would not have VTEC fuel and timing maps, correct?

If he had a good tuner, he could. The tuner could tune the chip for the whatever RPM the VAFC engages Vtec and leave the fuel curve alone on the VFAC so it doesnt affect the map on the chip.

A good tuner would have just added the VTEC components into the ECU and never messed with a VAFC

thats besides the whole point of this thread Stu.........

I never said a P75 with a VAFC was a "good" choice, just stating it could be done. I only asked about the VAFC because that sure as hell looks like a VAFC/SAFC harness to me and since he does have a P75 it made sense of having a VAFC on top of it.

Well I was just expressing that I doubt the chip has the VTEC maps on it because a tuner who would know to do that probably wouldn't use a VAFC to activate it. Which is why I recommend that he either get a P28 or convert the P75 to a P28 or P72 or whatever

Before you buy anything we need to sort out this wiring.
