    AEM X-Series OBDII Wideband UEGO AFR Controller Gauge HELP

    Desperately looking for help. Installed this set up to get a remote tune done and believed that it was full plug and play. No analog, no math corrections. Now my tuner is telling me that the readings are wrong. I've tried every option wideband channel wise with no luck. Can anyone help shed light on what I'm doing wrong? I haven't changed anything since the beginning of the tuning process, so I'm at a total loss. Below is the last log I sent. Any help would be very much so apprecaited.

    squirrel is using Phi as the unit...

    not lambda.

    maybe you have something screwed up in your AEM controller?

    can you change the units to lambda?
