p28 conversion?

[f20bcg3]

Can anyone tell me what all needs to be done wen switching to p28 obd1 from obd2b f20b using f23 harness and h22 upper plenum?

I don't think anyone has that exact setup here, but I could be wrong. I honestly think your best bet would be to contact Rosko Racing. I know he has a lot of knowledge on the H22/F20b setups.

If the upper plenum does fit onto the lower plenum of the f20b. All you have to do is rewire the iacv. You need to cut off the 3 wire clip and leave the black wire alone then the other 2 i think ones black and another color that one goes to the black on the h22 top plenums iacv clip and the other to the other color

Leave the iat sensor alone. The p28 uses it but say if your plenum doesnt have it, it is not needed. There is an option to turn it off on the p28 when you go get your car tuned. But the p28 uses everything that the obd2 does

^ Except knock sensor. Those get accounted for in the P72s but not the P28s.
