Trigger timing is as shown in the picture. Running direction is Counter Clockwise (wrt picture), 1st and 4th cylinder are at TDC. BTDC = 120 degrees.



Relevant trigger parameters:

primary_trigger=01

secondary_trigger=02

tooth_wheel=3A

trigger_tooth=0A

another_trigger_tooth=1E

crank_minper=50

tooth_wheel_twidth1=18 (decimal 24, that is 6 degrees)

tooth_wheel_twidth2=48 (decimal 72, that is 18 degrees)

ign_tdcdelay=78

ign_crank_advance=12

ign_out=70

ignchmax=03

h[0]=0F 00 00 00 00 00 00 00

h[2]=00 10 00 10 00 10 00 10


Previous problems to learn from:

I had issues with the triggering of the engine. The engine didn't run properly when set up for 120 degrees (trigger_tooth=0A and ign_tdcdelay=0x78; 10*6 + 120*0.5 = 120 degrees)). Remarkely it did run when setup for 60 degrees.

Although it is not clear what exactly caused the timing problem, after using [ALSfix] my problem was over and the engine started with the correct timing.
