Ok, I bought a used VAFC to use to tune my 92 civic since I am turbo it. well I was going to install it today and got to reading and it says excluding Vtec-E. I have a D15Z1 in the car with a stock P08 ECU. My questions are :1) can i wire it up but not hook up the v tech wires for the VAFC will it still work to tune with? & 2) If I do hook the Vtec wires up will everything be okay even though my car has the Vtech-E?
