Adamw Posted February 2, 2019 Report Share Posted February 2, 2019 You cannot derive AFR from a narrowband sensor, you will need a wideband device connected. Quote Link to comment Share on other sites More sharing options...
Blake Posted February 28, 2019 Report Share Posted February 28, 2019 how should I wiring in my wideband sensor to the G4+ plugin BMW E36? Quote Link to comment Share on other sites More sharing options...
Kenian Posted March 1, 2019 Report Share Posted March 1, 2019 Youll need to wire the 0-5v output from your wideband into pin 13 of your ECU (AN Volt 3) which is currently setup for NB Oxy and then got to AN Volt 3 under analougue inputs and change the function from "NB Oxy" to "Lambda 1" and then choose the calibration from the presets or input the calibration details from you your wideband controller. or you could use the AEM X-series UEGO that has CANBUS capability and wire it into your ECU over CAN and the link software already has this device setup as a preset stream. E36+.pdf the pin location etc is all in the attached manual for your ECU from page 17 onwards. Quote Link to comment Share on other sites More sharing options...
