Loading Tune corrupts mega2560 and never works again. #690

So I am fairly new to the Speeduino community. I have been searching for related issues but have not found anything. So I have duplicated on three different Mega boards. I loaded the latest release 202108 with speed loader. I then hooked up to Tuner Studio and created a project. Used the 202108.ini file and all was good. I was able to bring up the dashboard, connect and see data. I then started to make mods to the config for my particular application. I changed number of injectors, cylinders and size of engine. burned to mega. All was still good. Once I went to the Trigger setup menu. I left as missing tooth and put in 36 for primary base teeth. put 1 for missing tooth and just kind of left everything else default. Burnt that as well all was good. Then I went back to the Trigger setup and changed from missing tooth to the 36-2-1 and set the trigger angle to 10. Burned that to the mega and now it is dead. I only get "spe " out for a signature. I have reloaded the firmware multiple times both with Speedy Loader and PlatformIO and Arduino IDE. nothing Fixes this issue. Somehow it has corrupted the Mega? I have loaded other firmware for stuff I have done and it appears to work just fine so I am at a loss right now. I have been using Arduinos for many years and have never see this happen before. Like I said I have tried on three different boards they work just fine until I load in my .msq File, then they are dead to TunerStudio.

Alright so I found a fix for this. Since it was a config load that caused the issue I figured it was an EEPROM corruption issue. So I loaded the EEPROM_Clear sketch and ran it. then reloaded the speeduino firmware and now I am good to go. So there is something getting overwritten or squashed with this particular setting combo.

Sounds like there could be something buggy in that 36-2-1 decoder that is causing it to lock up. I'll try to reproduce here, but if you're able to attach a tune with everything except the decoder set, that should help confirm it.

Which tune did you use after clearing the EEPROM? The one that caused the lockup (36-2-1 and set the trigger angle to 10) or something else?

Closing as no response and I haven't been able to reproduce with this trigger.
