Default OBD1 Dizzy with OBD0 ECU!? MPFI, yet OBD1 Harness?

Like wtf? Haha I get this d15b swapped EF hatch with MPFI, but all the plugs are obdo and theres a bunch of splicing and taping to the harness connected to the obdo ECU 0.o

I bought a d16z6 Dizzy today and I made a jumper ( The Distributor Cables are spliced to obd0) and no spark, well the ECU is obd0 so its not compatible...!

If I get a p28 ECU can I just hook it up and not worry about the injectors or anything else ******* up? ***** pissing me off haha

If you're running obd0 injectors (low impedance), they need a resistor box. If they're OBD1 (High impedance) you don't need a resistor box. Both will run with obd0/obd1 ECU's.

If you want to run OBD1 you'll need a conversion harness between the obd0 ECU and the OBD1 ECU. Or you can repin it yourself if you have the pinouts. Less of a headache to just buy one from Rywire though.

Why not leave it OBD0 and run the original distributor?

Because the Original D15b VTEC came with a distributor that did not fit properly and would leak oil, and I wanna run VTEC...so where exactly would I find this at the junkyard like can I find it on a stock car or order it special?
