Hi , This is my first time using the ECU Master PRO. I’m having trouble with the trigger setup. I started with the Primary at 50 degrees (same as Black), cranked with a timing light and ended up at 102 degrees. I’m using the Secondary trigger as the Primary Teeth Window 3 to 10. After those settings are in I can see all cylinders and all secondary teeth are numbered on the scope. Still doesn’t want to run. I can’t find a Lock ign Timing function like on the Black so I just zeroed the table in the cranking section when I checked with the timing light.
I can’t upload attachments, saying I’m a new user, how can I get around this?
Could you please post a scope file from cranking and the corresponding project file.
You should be able to add attachments as I’ve increased your Trust Level.
Thank you, I knew the Lock would be there somewhere.
Hopefully Scope is attached.

The scope looks correct to me. The spark for cylinder 1 is triggered at 50 degrees on the scope.
Could you please post a screenshot of the primary trigger setup in BLACK?
I had been trying 50 degrees and 102 (and a few in between), will check again tomorrow with the timing light at 50 just to make sure and with the timing lock on this time.
This is the last S54 on Black that I did.
Thank you for the screenshot.
BLACK uses two parameters to describe the first cylinder TDC - First Trigger Tooth and Trigger Angle. After conversion, you should enter: 87 degrees into EMU PRO “Trigger Setup First TDC Angle”.
87 = 6*(360/60) + 51
I found something interesting in your scope: the maximum compression of the engine for cylinder 1 is at about 87 degrees. The red lines have lengths corresponding to the time between the teeth. Longer lines indicate a slower engine speed. So the TDC is very close to 87 degrees.
(My recommendation is below the screenshot.)
I recommend:
- using 87 as the first cylinder TDC.
- if the engine will not start, you can try to activate the Trigger / Secondary / Invert Engine Phase
That’s perfect. It needed the Invert engine phase to start.
I have carried on and calibrated the VANOS intake which looked like it worked fine and applied the new figures into the control.
The exhaust however, it died and it now doesn’t have the sync, the exhaust cam has moved outside of the Secondary Window (3-10) the cam moves around 9 teeth retard so now is sitting at tooth 115 instead of 3.
Can you help on this please?

You can change the Trigger Secondary Pattern to “N-1” or “Longer than factor 2.0”.
It will detect the highlighted edge. You probably need to change the phase again.
hi, I have noticed you have started measure time between the teeth in the trigger scope, so my dumb question would be, can we hope for something like cylinder contribution or individual power? kinda way to see missfire on ecumaster, maybe it was already implemented?
