Audi trigger 1.2.16 "hickup"

A customer with a Audi pnp unit has run for a couple of years with various firmwares and the way the car runs and behaves has steadily improved with tuning and better firmware features.

With 1.2.16 the car suddenly developed a strange mis-fire, or ignition miss, trigger miss, or whatever you can call it. Datalogs say nothing, except show that :

Reverting back to 1.2.11 and it runs normal again.

Can you tell from the configuration of the ECU that something causes this?

Increasing from divby3 to a higher number has not been tested, but that makes no sense as it handles high rpm well (or maybe the misses are not detected so easily at high rpm). Not the most logical thing to try yet.

Engine configuration

Other 115 coils have been tested to see if that was the problem before it was discovered that it ran fine with a slightly less recent firmware.
