I have a 97 hatch with a "Mini-Me" swap in it that I need to smog(Star smog). I bought the car this way and its been really reliable so far(I had it for a year now). I need to smog this car and I thought by putting the stock pcm back in it would be fine. Apparently the p28 that is in is tuned to make it run cause when I put the stock pcm in I have a Cel for IACV circuit. I did a little digging and found that it was a 3 wire made to a 2 wire IACV. So the orange signal wire is not even attached to anything.
The p28 has an adapter harness that it plugs into to work but I guess it is not hooked up to OBDII port.

Is there a way around this ?

 

Anyone ???

 

wat obd2 ecu are you using. you need the d16y8 ecu they use the 2 wireiacv

 

P2e !

 

the P2E is the d16y7 ecu and it uses a 3 wire iacv. you need a P2P, that's the ex ecu that runs the 2 wire iacv

 

Will that ecu plug into my d16y7 harness ?

 

yea It will plug into your harness, you might need a knock sensor and vtec needs to be wired

 

I would have to wire vtec to that ecu ? If I brought my car to you could you do this for me(I would obviusly pay) ? How long would it take ? How much are the parts ?

 

Well is vtec already wired. vtec and knock would take less then a hour to run and hookup. email me

 

Yes Vtec is already wired in and its running on a p28 ecu. It runs good with no problems and I get great mpg(37-41mpg hwy).

 

ok then we just need to wire the knock sensor. email me headsortailsmotors@gmail.com

 

Email sent ! Titled "Knock Sensor Wiring" !

 

Ok ! I purchased the p2p, knock sensor, and installed a new used Cat. Just need to wire up the knock sensor and potentiometer(for the fuel pressure sensor). I should be ready for smog in a day or 2.
