Been trying to figure out my 2g ECU. Here's my problem...
I recently bought a A/F ratio conditioner and the instructions are in Japanese. There are five wires coming from it. Red, black, white, orange, and blue. Obviously, the red is power and black is ground. I have those tapped into the ECU power source (pin 25 red) and ground (pin 92 black), but can't figure out where the others would go. One is a signal wire (white I'm sure...which would connect to ECU pin 76 which is the front O2 sensor return wire) and the other two (orange and blue) will be spliced into another ECU wire. This will let the condtioner tell the ECU to change the A/F ratio to meet my needs. But I can't figure out if I'm right on the white wire being the signal wire, or which wire to cut to make a correct circuit for the conditioner. If there's anyone out there with ECU knowledge or experience in changing the A/F ratio with a device like this, please let me know, going crazy!!!
Thanks!
