I have installed the O2 sensor just where the 4 pipes meet the collector outside of the cars front quarter panel. This is almost 30 inches from the port.

I am running a Holley Commander 950, and the sensor reads 0.02 (VERY lean). The manual says that installation too far away will show this reading.

My question is with heated vs. non-heated. How do I know what I have? Will a heated sensor allow this distance?

My only other option is to run it out of one pipe, or custom plumb the 4 into 1 (a-la DV style) into 4 and then into the collector, to retain the look on the outside of the car.

Is an O2 sensor a sensor is a sensor?

Thanks...
