you'll have to convert the engine to obd2 for your chassis, but you can still convert and use the obd1 ecu for tuning/daily.

get the obd2 crank pos sens and obd2 dist if i remember correctly. then get an obd2b-1 conversion harness and you can use the obd1 ecu. if you socket/chip it, it can be tuned for max power.
