im putting together the parts to put an eaton m90 supercharger kit on my 2.7. My question is can i use a non heated O2 sensor ie a one wire lead, to run my air fuel gauge?
will i end up getting a ton of build up on the sensor or will the exhaust heat burn it off?
i should add as of now i will be using a narrow band gauge and sensor to get the car to rough tune then later will dyno and wide band sensor.
thanks for any help
