Ignition outputs. FILL IN PROPERLY !
- cyl 1, EC36/35
- cyl 2, EC36/33
- cyl 4, EC36/36
- cyl 5, EC36/24
- cyl 3, EC36/34 (EC36/36 ??) Sparkplug is sooty, not as clean as other sparkplugs...
Cylinder 3 is sooty in ec36/34
note: dwell is 2.3 msec, does not grow with MAP (dwellmap=0)
dwellmap is 0 because we don't see any change in ignition power with higher dwell than 2.0 msec
ign TDC-delay (primary trigger settings) is too low !
- ign-tdcdelay = 20 is wrong....
Correction hint: 144+20=164 crankdeg = 15*6 + 74
- first trigger tooth should be 15
- "TDC after the trigger": ign tdcdelay = 74 crankdeg
- of course, rotate ignoutputs by 1 to match the desired spark position
- verify by strobe
Validation shows possible problem
- sectrig HALL-dirac filter: preferrably disable it !
- iac ignadv change should be lower (+2, -6 crankdeg or similar; even +1 -3 or crankdeg is more than enough is IAC air-valve is set up properly, +0 -0 should be good too)
With hall dirac filter the problem shows less times
Benchtest
We benchtested this config, and didn't found any problem.
We tested it 160 kPa and beetween 3000 and 7000 rpm.

The car is running normaly but when the boost is 0.5 bar and higher the car is missfireing because the weak spark.
- One cylinder is misfiring, seen on the individual power gauge (hotkey ALT-5), we suspect that the cylinder / ignition coil connected to ouput 3, ec36 pin 36 is your problem //Emil

I think the primary trigger setting and h0 is incorrect
- you mean tdc-delay ??
