    Default MTX-L showing 127AFR and 40V

    MTX-L hooked up through analog A1, was working great up until today. On data tab while monitoring voltage is showing 40.2V and AFR is at 127! Voltage from gauge wire is around 2.5 at idle when I disconnect from the V2.

    Any ideas?

    Gauge shows nothing abnormal. 14.0-15.0 range

    Went to make another run and it was working properly. Looks like it just needed a hard restart. Have never seen anything like it before.
