I have the aem wideband that was purchased brand new. Car is running fine and I have a tru boost that is working perfectly. My wideband is connected through the emanage harness and is getting power. When I turn it on it cycles through all of the normal startup, but it doesn't read at all while at idle or under power. I have the white wire from the wideband connected to the supplemental harness on an emanage ultimate to do the a/f target. I don't know if that would cause the wideband to not read. Anyone have any ideas?

Take off the white cable and if you can change the o2 sensor

Do you think it's possible the white cable is impeding the reading on the gauge? Wideband is brand new so I don't know how or why the sensor would be bad already.

Double-check the wiring. Make sure you know which is wideband output (0-5V) and which is narrowband simulated output (0-1V).

Well I unplugged the supplemental harness and it still wouldn't read to the gauge. It's really strange. It powers on like everything is fine but it only has three straight lines instead of showing an AFR reading.

Is the gauge grounded? I believe it needs to be on a good ground. Also, did you run it through the calibration?

JO TECH

No but in case. what the gauge reads???

Are you running both the power and ground to the greddy power output? You should be if that's where you are getting your power..
Mine was hooked up this way when I had it and worked fine.
