    Default Wideband data logging not working despite correct connections

    Hi All,

    Have just spent a frustrating day trying to get an AEM x series afr gauge working with 7.5 logging.

    The serial connection appears to be working fine, the flashscan displays the same data when running as the aem gauge displays, the problem I have is the data is not correct in 7.5 logging, it stays static at 10.16 when the afr gauge is reading between 12.x and 14.x.

    All other pids seem to be logging correctly, the flashscan is setup with the aem wideband, series pids enables. This is on a gm e67.

    I think the hardware is ok and it’s a software/user error, so any tips or things to try would be greatly appreciated.

    Cheers

    AFR 7.5 indicates no data getting thru (did you swap Rx/Tx wires...?).

    You might try the analog connection (the AEM updates 10x faster than the FSV2 serial connection).
