obd0 - obd1 MPFI?? - TriStateTuners.com :: Home of Tristate Auto Enthusiast

So, I have an '89 ef with a d15b. I did a MPFI swap to it. The car has been running a little rough lately and I thought maybe I needed a new IACV or TPS. Well as I go to pick up these items a friend and I realized that the car has an obd1 tb and harness, and an obd0 dizzy.

I have a PM6 which is obd0. I'm thinking maybe just a obd1 dizzy and ecu would fix the problems and maybe finish the obd1 project lol?

I don't want my car a halfie anymore!

Also I'm not sure which ECU is right for MPFI/OBD1, if it matters.

Input is much appreciated.
Thanks in advance!

My input is swap another motor, preferably a bigger one in.

I mean, it def doesn't help being half obd0 half obd1, pick one and go for it

You can not run an OBD1 map sensor on a OBD0 ECU, the voltages are off. Sounds like you would be better off running on the whole OBD1 setup.

You will need more then ECU and distributor to convert it over, will need a 4 wire 02 and a jumper harness as well.

What ecu are you running now? The pm6? I would just go back to running a obd0 harness and ecu if you don't plan to do many mods to it. Much better than running some frankenharness.
