Summary of change:
I have very strange misfire problem with one car. 4cyl inline engine, 60-2 on crank(vr), cam sync(4pulses, 3 filtered). 4cop, big injectors, 1.2.20 firmware(can't try older, because car has DBW). Car work great on low boost http://www.vems.hu/files/DamirMuha/1.2.20/v3.7_n008036-2014.01.20-16.10.19.vemslog But misfires at a bit higher boost http://www.vems.hu/files/DamirMuha/1.2.20/v3.7_n008036-2014.01.20-16.15.28.vemslog Problem is that misfires always on the same rpm and problem isn't in coils/spark plugs ...(change coils, no effect, change spark plugs, no effect, regap from 1.1mm to 0.5mm no effect). Also no trigger error in log. Do you see problem in config? Any suggestion what to try. Q: Damir, at what RPM in log does the misfire occur to narrow the search range ?? - DB A: after 5000rpm, only few times(you can see lean lamda few time, also rpm are a bit chopy at that time). That is strange, misfire sound like 100% sparkcut for very short time. Fuel pressure is stable(analog ch2). I can send you more than 100logs with misfire if you want.
