My Scan Gauge doesn't record data when the engine is off and has trouble restarting.
I kill the engine with a kill switch on the IGN fuse.
ScanGauge is V4.02
Watch this video because it is hard to explain.
This was just after a reset of all settings. not calibrated or any settings changed.
After many kills and starts of the engine as I have shown both key starts and bump starts.
It will not restart now on its own after the final shutdown at the end of the video until I either keep unplugging it or giving it a certain amount of time to reconnect. over several more stops and starts of the engine it might reconnect.
