AFC hack help
 

WHen wiring up a AFC for a turbo setup, the blue wire goes to the O2 signal connection at the ECU. Do you cut it or splice into it, I am not sure about that. But would that be the same as installing a A/F ratio gauge to pick a voltage from the sensor, I amlost on that.

You should solder it to the signal wire and not cut it. If you have an idea of what voltage you should be looking for, then it would be a decent way to measure the a/f ratio. You would probably need a dyno to figure out exactly where you want to be on the AFC.

BTW, wrong forum. :) Engine management covers things like this. ;)

haha, definetly needs to be in the emgine management forum. From what I have heard that if your turbo the o2 voltage should be around .9 or so.
