Hi guys, can You help me with configuration of primary trigger on Ecumaster Classic in Renault 1.4 K7J700 engine. Renault 1.6 K7M has same trigger pattern I think.

I used information from this forum and I managed to run the engine but still I have problem with First trigger tooth, I don’t know which value is correct.
what’s your current trigger settings?
If you have the engine running it must be close, use a timing gun and lock the value to dial it in the last few degrees.
I can’t be of any help for that engine specifically but in general I can. The help guide in the software explains the Ecumaster Trigger settings method decently well, with visual aids.
This is hard to explain over text but I’ll try
Goal is to find TDC, if you’re rolling the engine over by hand get it to TDC. Then look at the trigger wheel in relation to the sensor. How many teeth are in between the gap and the sensor (in engine rotation direction) is your first trigger tooth.
Then the angle is how many degrees of rotation between that tooth being measured by the ECU to where TDC is. A method of fine tuning. This will need to be done on every engine as a check even when copying settings.
with a 60-2 wheel changing the “first trigger tooth” setting results in a 6* change. You ideally want the angle around 40-60*, it limits your maximum ignition advance so you want to make sure you’re well above that. If you’re timing it and it the angle is too small, subtract a tooth and add 6*, check with timing light.
to check with a timing light check the box for “ignition angle lock” and set to 0 or whatever the timing marks on the pointer/damper allow for. adjust the trigger angle until the timing light and the number in that ignition angle lock box agree
I strongly reccomend using a Falling edge for trigger edge. Wiring polarity makes a differencen but if it’s wired correct and your using falling that’s always been the most stable for me.
That’s a good explanation by @FloorItGarage.
@Mati, if you need a further details, there is a how-to document on trigger settings for EMU Black. While there may be small differences compared to EMU Classic, the core concept remains the same: https://www.ecumaster.com/files/EMU_BLACK/How-to/How-to_Configure_Trigger_in_EMU_BLACK.pdf
