Adjusting timing on a 1991 Acura Integra LS?
So two days ago I wanted to adjust timing on my Integra 16 degrees BTDC. So my question is when I bypass the computer to adjust the timing shouldn’t the engine check light come on right? Because it would not and I’m 100% sure it was the gray connector w/ the two wires by the blower motor. I tried many times I connected the wires from the back and the front of the connecter. Any help would be much appreciated.

The check engine light will not come on when the bypass is used to adjust timing. The bypass connector tells the ECU not to advance the timing, so that when you are manually advancing the timing, the ecu doesn't automatically push it forward. The check engine light is also bypassed when the bypass connector is grounded. Additionally, I had a high compression Integra engine that I drove around for three months with the bypass connector in use, and the car never turned on the check engine light. I did it to avoid pinging. Good Luck
