Hey guys,

I currently have an EK3 Civic (3 Stage VTEC) w/ Manual Tranny. I have a boost project in mind but since the P2J is OBD2, forced induction is pretty much out the window.

My question is, would reverting to OBD1 using a harness conversion be possible ?

I have been around PGMFI.org and have seen some threads about the P2J-0 ECU and some speak of using a P72 ECU + IAB but nothing really concrete. Also all of the threads seem to be completely dead.

Anybody have any insight? short of swapping out this motor, which I have contemplated

TIA guys!

 

JDM P08 ECU, it's the OBDI D15B 3 stage VTEC ECU. After you get the jumper harness, you have to wire in a one-wire O2 sensor though, otherwise you'll get a CEL.
