I am looking at fitting an AEM Wideband sensor and EUGO controller with CAN and 0-5v outputs on it.
The thinking was that this could be connected to the Garw dash inputs to show real-time A/F ratios, but also I could fit it in place of the original narrow band sensor in the turbo down pipe and not have to weld in an additional sensor boss and run 2 sensors. I would just connect the correct 0-5v output to the original narrowband sensor wring and maybe a resistor in the original sensor heater circuit to avoid the EML coming on.
Has anyone else replaced the original sensor like this and has it worked OK?
