cause & solution

Thanks for the ideas and suggestions. The issue occurs with both 8 and 6 gauges per page. Both of the O2 sensors go to 0.000 immediately when coasting in gear.

The issue occurred after changing Pwr off Retries from 5 to 33, and went away with the setting back on 5. Increasing to 22 brought the issue back, but not as badly.

Raising the force MPG sensor by 5 or 10 points might be a remedy, but I will need to do more testing to make sure and to fine tune the setting.
