Try flywheel mode 22. Your cam pulse isn't on tooth 32/33.

Thank you, but Flywheel mode 21 is Rover with single Point Cam anywhere.
Mode 20 is for tooth 31/32.
Mode 22 is Renault.

No, I do not.
22 is Renault 30-2 crank. ?
Rover is 36-1.

Sorry, I misread that. 21 is what I meant.

I'm not sure why yours doesn't work, it looks identical to Rob's from before.
I'll have a look at the code in the morning to try to work out why yours isn't working.

Thank you Alex.

Here is my map if it helps maybe?

I have 280° camshafts and vernier pulleys.
The exhaust cam with the cam mark is about 6° Retard on the crank to the OEM camshaft timing.
The cam mark itself is the same like on the OEM camshaft.

Regards
Carsten

Actually, I can see the problem.
The cam pulse should be on tooth 14, your is on tooth 13.

I don't know enough about these engines to say if that's a mechanical issue.

I edit the post above.
Ok the teeth is wrong because I have another cam Timing as OEM.
So I have no mechanical issue. :mrgreen:
Can I adjust this with Swin that the ecu accept the cam Signal at tooth 13?

Edit: So I have to set cam sensor Position to -6 or -10 for one teeth in sequential Settings and thats all? :?: 8-)

I don´t know why but now it is sync with teeth 14. :shock:
I test it multiple times and with crank sensor at 286 and 292 as I have measured with the ignition lamp.
With both values I have the cam on teeth 14 now.

Here is a Picture with engine running.

But in engine diagnostics nothing changes?
Cam 1 Sig tooth 14
Cam 1 Angle 0
Cam Pulses received is increasing steadily so the ecu see the cam sensor.
But if I enable the sequential injection the engine stops an will not start.
Without it the engine runs fine.
I have checked the Wiring from the injectors Output .
It is ok
Cyl.1 on Inj.1
Cyl.3 on Inj.2
Cyl.4 on Inj.3
Cyl.2 on Inj.4

I play with the cam sensor Position but nothing helps?

I use the OEM wasted spark.

Here my map again. Perhaps you can see my fault???
I don´t know what I can check now or what´s my fault???

When the engine stops, do you get any cam sensor errors in the Diagnostic Display?
