Quick question. I am installing an AEM UEGO gauge. I noticed that the AEM gauge has no wiring harness or connections for the stock O2 sensor wires.
My question is, what role does the rear O2 sensor play in stock ecu tuning. Does it play a role in fuel tuning, or is it only for a 02 check after the cat.
By the way, my cat is removed.
Anyhow, if the rear O2 IS involved in stock fuel tuning, I would like to mount the AEM in a new location (in between the stock front and rear O2 sensors). If the rear 02 IS NOT invovled in tuning, I would just replace it with the AEM gauge sensor.
Thanks
