OBD-0 to OBD-1 conversion
Well Ok. I have decided to do the Obd-1 conversion to my LSVTEC CRX HF. However, I have not found very many helpful websites (step by step guide).. The parts I need are:
P28 ECU
92+ VTEC Dizzy
92+ O2 sensor
conversion harness
I think I need the OBD-1 fuel injectors???? What happens to the resistor box??
Can someone shed some more light, am I heading in the right direction?
Am I missing anything???
Please help!!! THANKS

All you need:
1. Obd1 ecu for your setup (chipped or stock etc..)
2. Obd1 distributor for your motor.
3. 4 wire o2 sensor (can be disabled with a chipped ecu)
4. Obd0 to obd1 ecu harness
5. (Optional obd0 to obd1 distributor jumper plug)
Concerning injectors, you can use obd0 injectors as long as you keep the resistor box (assuming they are low impedance).

I just did it it is really straight forward, Just make sure to track down the wires that go into your OBD0 harness (knock sensor, Vtec pressure switch, Vtec solenoid, and old Oxygen sensor wire) On mine those wires went into the stock OBD0 harness.
