The use of an OBD-1 (92-95) ECU is needed for proper tuning of your high performance engine.

The SpeedFactory OBD-0 to OBD-1 ECU Conversion Harness for Multi-Point Injection allows you to use a JDM or US OBD-1 M/T ECU in an OBD-0 Chassis (88-91 Civic, CRX, or 90-91 Integra).

We designed our harnesses to be superior to other versions available on the market by using original equipment style ECU pin connections on all plugs, lengthening the harness leads to 7" and by using durable automotive grade wire that exceeds OEM specifications.
