What ECU(s) for b18b into 91 CRX Si? any wiring mods?
Trying to get an obd1 b18b to run in a CRX si that had a B16a1 in it. First what ECU would be best or even work pretty well. Any wiring changes between the OBD2 b18b and the OBD0 b16a ? I'm just thinking distributer. TIA

The easiest ECU to use for plug and play with the cabin harness is a 1990-91 PR4 LS ECU. Since the car is a Si and already MPFI, using all OBD0 stuff will make it completely plug and play with no additional wiring.

Doesn't the 1990 pr4 have an external atmospheric pressure sensor while the 91 has it built into the ECU itself? If the 1990 pr4 does have this configuration what is need to add the external sensor?
