    AEM 30-0334 Freeze during logging?

    Hi all, I'm having some issues w/ logging my wideband..

    I'm trying to log my 30-0334 AEM wideband via analog w/ HPTuners. Everything is setup correctly (as far as I can tell). I'm running the most recent version of HPT. I have resynced etc -- I have the Pro feature set etc..

    The PID is setup as External sensors -> MPVI2 -> analog 1
    I have the transform setup as Oxygen sensor -> EQ -> AEM 30-(03x0 etc)

    When I hit connect to vehicle and then start recording, the PID reads the same as the gauge itself. All good here!

    As soon as i start the car, the PID freezes at that value and never changes..

    Meanwhile, the gauge continues to function properly...

    any ideas??? Thanks a ton! Been searching for a while - cant seem to find anything other than this..:

    So apparently I'm not that bright, or no one else has done this.
    The solution is to start recording after the vehicle is running..

    Lol

    In that vein, DO NOT start the car, once the sensor has gone through the HEAT cycle. That is how you kill WB sensors.
