Thanks for help.

Cant understand why i must have a custom fireing order..

[Chris]

Is the timing correct on number 1 cylinder?

Chris

[BMW M50 TURBO]

Yes the timing on syl 1 is okay now when i have custom fireing order.

But that is when i just crank the engine.

When the engine is started it is very dificult to read the timeing because i cant get the engine to go steady enough

[Chris]

Put the ignition output setting on 6cyl ws. Try a lead angle of 420 degrees. Add or subtract in 120 degree increments until the timing on number 1 cylinder is correct.

I dont know why people insist on using the Bosch 839/842 injectors when there are supoerior injectors available on the market today.

What injectors do you mean i should use

[BMW M50 TURBO]

Is it sylinder i/p lead angel you mean?

Change from 60 to 420?

Should i just crank with starter or try starting

[Chris]

Yes cylinder i/p lead. Set the base fuel multiplier to zero and crank the engine. Get the timing set then turn the fuel back on. ID2000 are a much better injector.

Then i have change back to 6 ws.

Found the timing at 180 degrees.

I can't understand why?

The timing on the engine is right!

Is it my 3 tooth wheel so it's wrong?

[Chris]

The SM4 expects to see the sync pulse after the number 1 cylinder pulse. If your lead angle is 180 it means the sync pulse is not after number 1 cylinder, but after another cylinder.
