This is making more sense now as to the root cause and the MTX plug in not catching certain stuff for some reason.
I was able to replicate the save issue on any file, so I did it to a stock file and posted that above. Winols finds 1 error that MTX, ME7check and ECUFix all miss for some reason.
Beyond that, I am still baffled what smoked the ecu??? Was it when i tried to start it? I have dealt with checksum issues before and the car would always start and run once then never again, never in 3 second pulses.

What address are the corrections applied to? |

That might be a bit over my head, how do i see that?
The 3 files in the first post will probably tell you more than I can.

Step #3: Reading Multipoint Checksum Blocks...
1) <14224> Adr: 0x024000-0x02658D Chk: 0x0B08F804 CalcChk: 0x0B08F804 OK
2) <14234> Adr: 0x014000-0x014243 Chk: 0x0054AC79 ~0xFFABF016 INV NOT OK CalcChk: 0x0054FAC1 ** NOT OK **
3) <14244> Adr: 0xFFFFFFFF-0xFFFFFFFF END
yup. its the one phila found.

So what's the verdict? That area isn't checked?

Worse:
1) ME7Check doesn't check it
2) MTX plugin apparently corrupts the MP descriptor block such that the checksum/inv pairs are wrong (so my first attempt at detecting them FAILED on ST's first image)

So we have a bug with me7check. That's kind of a big deal considering how many people rely on its output to verify if a file is safe to flash. I guess the bigger issue is that the mtx plugin corrupts the file further.
I still don't think that this could physically damage an ecu though.
I'm going to flash this file to see what happens.

If i understand you correctly Nye, then even though only one checksum was actually bad it shifted it all and made it to where they were all bad?
Could explain the mega bricking that occurred, throttle body adaptation that never wanted to stop and so on. Bummer. Waste of a perfectly good ecu. If MTX wasnt 12 bucks that has paid for itself 1000 times already I would be bitching to him right now.

Naw. its just a single value. Could explain the mega bricking that occurred, throttle body adaptation that never wanted to stop and so on. Bummer. Waste of a perfectly good ecu. If MTX wasnt 12 bucks that has paid for itself 1000 times already I would be bitching to him right now.
I don't think this should cause bricking, let alone ECU damage... |

when I get to my shop later i will open up the ecu in question and see whats what. Maybe try flashing it again if it doesnt look super burnt. But the smell and temp were unmistakable to a fired board.

No communications after power cycle. Bootmode and it's back to normal. No detectable increase in heat produced.
EDIT:
I still wouldn't recommend flashing this. I flashed it to an ecu that has seen better days that I keep around just to play with.
