If you did a '93 b18a1 swap into a 91 civic i was told you change the distributor and ecu to run obd0 in an obd0 car.

I changed the distributor and i also got a pr4 ecu...the car is turning over and won't start...do i need a pg6 ecu which is from the 89ish integras, is that obd0?

And does that make pr4 obd1, or wtf?

 

?

 

2 options:
- go obd1, use what the engine comes with and just get a harness adaptor
-stay obd0 and buy and new dizzy and ecu from a 90-91 Integra

 

If it plugs into your stock wiring it's obd0, sp meh, might not be the ecus fault.
