just wanted to get other's thoughts on this data log, big spike and then motor damage appears to be from detonation.
I've attached the calibration and datalog.
thank you!

Whats the setup? Ignition timing actually goes down at the spike, wouldn't think it would be detonation. The motor is cold so there is timing be added on top of the main table.

Even before that you can see the rev limiter going on and off very rapidly. I suspect the issue may be from the overheating error code that has been set.
