FITTING AIR / FUEL GAUGE WHERE DO I CONNECT WIRE ECU OR LAMBDA
Half way into fitting air fuel gauge what i need to know is do i connect the sensor wire to lambda sensor wire in engine bay or can i connect to the o2 sensor wire on my ecu,I know o2 sensor is the same thing as a lambda i think its just will the ecu give the same reading or cause problems connected that way.thx
The AFR gauge you are fitting is probably a wideband gauge. the std sensor will be narrow band so almost certainly wont drive the gauge even if you get the wires connected.
Do you have a sensor hole in the downpipe that you can put the new wideband sensor into ?
