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

Earlier, a 15-1 was used, and support was added for that.

For this engine, without any consultation, 10 crankteeth were made instead of 5. This has no advantage, only disadvantages. At minimum, config changes are needed.

After 1 tooth broke off, it became 10-1. Unfortunately this trigger is not supported for 5 cyl. The 15-1 and 60-2 cranktooth (with camsync) uses a special case, so they avoid tooth 14(=2+6*2) and 58,59=(10,11+24*2). The special case for 10-1 is not implemented, and since this toothpattern is unreasonable, it might not be supported later either.

Notes:

tooth_wheel_twidth=90 (36 degrees ! 18 degrees as in your config is simply bad)
for 10-1 Nminus1 flag must be set (primary_trigger=11 not 01)
- but it will not work

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.Under cranking 200RPM the followings can be seen:

Spark on #1Cyl is at TDC.

Spark on #2Cyl is 8degs BTDC.

Spark on #4Cyl is 10degs ATDC.

Spark on #5Cyl is 10degs ATDC.

Spark on #3Cyl is 5degs ATDC.

Car runs with these settings.

Spark with 1100RPM and 13degs in MT shows 0-25degs variance all the time on all cylinders.

The idle quality is very bad.

Log is sent to email address.

Spark at 3000RPM 32degs in MT strobe shows 70degs fixed ignition advance.

and the dump also from 1.1.27 FW:
