Auto DPFI OBD0 to Auto MPFI OBD1 Conversion question
I’ve searched this forum and so far saw nothing pertaining to this exact dilemma so far.
Alright so recently I wanted to attempt doing an obd0 to obd1 mpfi swap on my automatic 1989 Honda Civic dx hatch, and I’ve run into a really confusing wiring problem that i can’t find any information on to make this happen.
I have a P06-A52 ECU
I’m trying to figure out how to re-pin this obd0 to obd1 jumper harness to make it work for an automatic ecu instead of manual ecu so I can just plug it in and be done with it, but I can’t figure out what wires to swap around or add to allow the ecu to work with automatic and shift properly.
Im not trying to swap my transmission to manual because of traffic reasons, limited space and money and whatnot, so I’m trying to keep my automatic and still make this possible.
My last resort if this cannot be achieved is just getting a PS9 (I believe that’s an automatic MPFI ecu,) and keeping it obd0 which I was trying to avoid doing.
if anyone needs the pinouts to look over, here’s the links. Any help is appreciated
