I am trying to cancel the OEM primary O2 sensor and connect the AEM wideband (brown & white wires) to the factory O2 sensor blue plug on the car in order for the ECU to get the signal directly from the wideband but the flashpro manager doesn't read any value on idle. It keeps reading 14.7 AFR without changing at all and the digital display shows 9.6 AFR.
Am I missing something?
AEM Wideband as primary
Re: AEM Wideband as primary
You cannot do this. It cannot run closed loop from anything but a factory O2 sensor. You need to keep the factory sensor connected and you can use one of the inputs listed in the calibration window under Lambda in the Closed Loop section to input the aftermarket wideband signal to the ECU for datalogging only.
