I've been told I can back-date an OBD1 distributor to run on an OBD0 ECU. what's involved? do I simply re-pin the connector to fit my wire harness? I have an extra PR3 ecu from my other project, I was going to chip it and run some stock D16Z6 maps and back date the distributor. Should I run a 1wire o2 or can I run a more accurate 4 wire?
