AlexLSX7 Posted April 15, 2023 Report Share Posted April 15, 2023 I have two AEM wideband x series running into my G4+ Xtreme via can. At idle the gauge for example will be reading around 13.5 but the the ECU is reading around 9. If it hunts a bit it will go up as the gauge goes up. I've had them on the car working before. The only thing I've done recently is update to the latest (and I assume final) version of the software and firmware while I was rebuilding my turbokit. Is there something I need to change somewhere?

Adamw Posted April 16, 2023 Report Share Posted April 16, 2023 You would be best to compare in lambda rather than AFR. What do you have the stoichiometric ratio set to in the ecu and gauge? Quote Link to comment Share on other sites More sharing options...

Adamw Posted April 16, 2023 Report Share Posted April 16, 2023 Can you attach your tune and a short log - even with the engine off will be fine. Quote Link to comment Share on other sites More sharing options...
