FILL IN PROPERLY !''' * cyl 1, EC36/... * cyl 2, EC36/... * cyl 4, EC36/... * cyl 5, EC36/... * cyl 3, EC36/... (EC36/36 ??) Sparkplug is sooty, not as clean as other sparkplugs... note: dwell is 2.3 msec, does not grow with MAP (dwellmap=0) ---- '''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) ---- Log: http://data.hu/get/6496900/v3.3_u003132-2013.05.01-12.33.07.vemslog 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 New log: http://data.hu/get/6502250/v3.3_u003132-2013.05.03-16.34.38.vemslog I think the primary trigger setting and h0 is incorrect * you mean tdc-delay ?? with the current config when the tdc delay would be -10 degree then the sign would be in place on the crankshaft. Can you count the correct setting for this config?
