I just put a '95 p75 ecu in my '00 hatch w/ a y7. Now, the only code my stock ecu was seeing was my o2 sensor, no cat. When I plugged the p75 in it tripped a code for the iacv, code 14, and of course idled terrible. I have checked everything and it looks ok. If it is the iacv wouldn't it show up on both ecu's not just the p75 or am i just missing something or is the ecu junk? Please help!!!!!!!

 

the y7 motors run a 3 wire iacv ... the ecu your running is for a 2 wire i belive....

you need to do some minor repinning and wiring i think ///

 

wouldn't the conversion harness take care of that? If not what do I need to do? Thanks
