hey everyone, it seems to me that i have a problem....
i got a 1990 CRX Si with a d16z6 VTEC and i also have a APEXi VAFC but since my ecu is a non vtec how do i hook it up????? any help will be greatly apprecciated!!!

 

Ok do you have the instructions?? go to apexi site (www.apexi-usa) unless it changed.. if your using stock d16a6 ecu(pm6) then your wiring diagram is H1-a.

Follow the diagram on page 12 [h1-a] connect everything to signal harness.. except the VTM and *Pressure. Then run a direct line from the vtec solenoid in engine bay to the v-afc unit(purple wire) there is no need to run the wire to ecu(which is pink wire.dont use or splice into). Now your done, will take 2 minutes to do that if wire is connected to selonoid and already through firewall.

*You dont need to splice the pressure wire for the v-afc to work, but it's good for a electronic boost gauge. If not FId then it just reads system vacumm.

Also I hope your soldering all the wires and using rubber caps and then elec tape it all up. Do it the right way.
