    Anyone works with PLX SM-AFR wideband on E83 - E78 ?

    I am planning to get PLX wireless AFR gauge and shows on android phone.

    I could install wideband sensor instead of upstream-sensor1 , and 0-1V output could connect to E83-E78 but needs to connect heater pins too .
    otherwise can gives DTC about heated circuit foult. I ask them if they have information about this issue , they couldnt inform me and ask through this issue by forums.
    Do you know if SM-AFR support sensor heater circuit simulator output ?

    thx.

    not worth the time... and no one simulates a heater circuit with their widebands...
    its not any more accurate than the oem unit. just install it separately and use the 0-5v range to tune with the mpvi module.

    if you want to test it go ahead but your real limitation is the fact your cramming everything into a 0-1 volt range. the accuracy comes from expanding that range to 5v
