Hello.
I have problems to configure my M4 on a cliosport group n car.
Its a special flywheel pattern, 60-1 + a long tooth, a tooth with no gap between 57-58.
I did see somebody else use ref/sync mode 81 and tooth ratio 50. I have to use sync mode 83, but the strange thing, if I use tooth ratio 50, I get a lot of sync errors and no signals out to coils, but my cranking rpm are normal. If I set tooth ratio to 80, something something start to happend. The ecu send out signals to coils and injectors, but when I watch my ignition lamp, its unevenly signals.
Is the flywheel pattern due to my problems?
Is it easier with a M400?

Hello again!

Does anybody have a good idea?

Next weekend rally championship start in Norway...

And, sorry, its 57 small teeths, 58 is a long tooth without gap.

Are you able to send an oscilloscope cature of the crank signal? I assume this has a magnetic sensor so an oscilloscope is the only way you will be able to set it up anyway.
