I have a 93 Civic coupe and I swapped out the old motor for a D16Y8. A friend of mine gave me his 93' chipped VX ecu. I plugged it up to the harness and everything worked fine except the VTEC activation. What wires do I need to graft in order to have the ecu control the VTEC engagement?

Thanks.

you need to add the wires for vtec. a4 for vtec solenoid and d6 for vtec oil pressure

Thanks for your help. What do I do about the wires located at A4 and D6? The oil pressure switch has two prongs, is one dedicated to ground and one to ecu pinout D6?

what ECU code is the VX? I think you want a p28 ecu not a VX ecu. The VX is supposedly tuned for economy not performace, someone back that up.

not to mention it uses the 5 wire O2 sensor.

i think the vx ecu is a p09 or p08 something like that
