For Audi 20VT engines the

following triggers make sense:

factory (135 crank, 1 crank, 1 cam)
60-2 - easy to install gasket at the flywheel
5 cranktooth, 1 cam

For this engine, without consultation, 10 crankteeth were made. This has no advantage, only disadvantages. Config changes are needed.

After 1 tooth broke off, it became 10-1.

Upload config dump, so we can review.

Notes:

tooth_wheel_twidth=90 (36 degrees ! 18 degrees as in your config is simply bad)

Nminus1 flag must be set (primary_trigger=11 not 01)

We changed these setting to ENABLED in megatune,but this had no effect.

camsync position must not be too close to missing tooth !

oscilloscoping needed?

in worst case another 4 can be removed so it will become a 5+1 trigger

Is this 1.1.27 ?yeah.and the other too.

Worst case scenario is now active,we now have 5 pins on the crank and 1 one cam signal.

this is how it looks on an oscilloscope:

RPM reading is ok with this.

Spark on #1Cyl is at TDC.

Spark on #2Cyl is 8degs BTDC.

Spark on #4Cyl is missing.

Spark on #5Cyl is at 72degs away.

Spark on #3Cyl is sparking everywhere.
