Ok this is gonna sound weird but I need to know if I can make this work, it's a crutch mind you so don't tell me to just go buy a P28 ECU.

Anyway I have a D16Z6 in my cx, it turns out the P28 ECU that came with the car is shot, making the car misfire, I believe it also made the car not see the 4-wire 02 sensor. Anyway I threw in my old cx ecu (P05 I believe) now I need to know if I can get the 4 wire 02 to work with this ECU and two if I can rig some sort of rpm activated switch to my vtec sensors to kick vtec on. In the end I want to either re-wire the car and get a p28 or rewire for a standalone. But anyone have any ideas? Thanks, pinouts for the p05 would really help

 

ecu pinouts
hope it helps

 

honestly a p28 will save you time and money in the long run. If you just want the car to run, throw the CX ecu in but it will run like **** even if you rewired it. the fuel/timing will be off.

 

how about a apexi vafc or a fields unit? I hear the fields is much cheaper, where can I get one? and can I raise my rev-limiter with either unit?

 

its possible that the P28 can be fixed and its a fairly easy one . if not, I can definalty make the P05 into a P28 ecu if you are interested.
