According to the Service manual the ECU reset procedure is the following for a 2nd gen Integra:
ECU Reset procedure. (Perform every time when troubleshooting)
1. Turn the ignition switch off.
2. Remove the BACK UP fuse (7.5A) from the under-hood fuse box for 10 seconds to reset ECU.
CANADA: Remove the HAZARD, BACK UP fuse (10A) from the under-hood fuse box for 10 seconds to reset ECU.
(The following is not found anywhere in the service manual, but makes sense, so I follow it.)
Now when starting the car, let the car idle for 5-7 minutes with all accessories off and don't press the accelerator at all. Let the car warm up to normal operating temperature before pressing the accelerator. REMEMBER DON'T PRESS ON THE GAS PEDAL UNTIL IT HAS WARMED UP FOR 5-7 MINUTES. When the car has warmed up for 5-7 minutes turn the ignition off. ECU has been successfully reset.
