Switching to an invalid map is interesting... We will have to wait for Terry to hear on that. Sounds like you are triggering a switch to Map 4 some how, either lean or over boost or whatever, and there is something going on there, so it is kicking to map 0. Can you select map 4 on your own with no problems?

I would reflash your jb4 with a laptop instead of Bluetooth, to be sure all hex is perfectly flashed. Then try to dial the tune after that. Logs will help too brother. Sorry for the half-ass support, like I say d, Sunday family day!
Just an update: I got a BMS data cable and it seems to be working okay now. Need to do more testing, but it looks like it actually was a problem with the bluetooth. For those of you who might have this issue going forward, hopefully this helps you out.

Many thanks to CedarPerformance for the tip!
