Hello! Pro 16 (board rev. E) on VR6 Turbo have some problem on peak hp and peak torque (5300 and 6200rpm) with missfire and dwell time increase just for cylinder 1and4. The dwell time is set to 2.5 ms for r8 coils.
I tryed:
-new coils
-new spark plug
-new harness
-improve ground
-new crank sensor
-adjust spark plug gap
-filter trigger adjustment
Last setup was built with ecu master Black and the car runs great.
Since last setup I changed harness (new one), light flywheel, bigger injectors.
Let me know If this scope looks good…

Can be a trigger error?
And a log…

Hi,
You have selected the wrong edge for the primary trigger.
Now, you have an edge detected where the gap is supposed to be.
Change the edge to falling for primary, and you will have a constant edge distance with a proper gap.

I already tryed that to change to falling and same problem. I will post a scope with falling edge. Thank you!
not this. Just courios if it is ok…
And something strange in log ignition event looks weird 6-4-3-2-3-5-1…

This is because of the incorrect edge selection for the primary trigger.
Cylinders 1 and 4 are around the missing teeth.
Wrong gap detection meant that dwell time was off for those cylinders.
That’s just because the logging frequency for that channel is too low (10 Hz) to see every ignition event number.
I don’t see signs of misfire in this log.
No RPM drop, no lambda spike.
Do you have a different one where you are sure the misfire occurred?
Please, also post your project file.
