Not sure what caused the issue, but it was running fine some while ago. Log file running fine (except O2 sensor not connected and not tuned at all, so VE, ignition and other tables are more or less ok only at low RPM): http://www.vems.hu/files/Gachax/v3.3_u004705-2013.09.01-15.49.40_ok.vemslog Log file - not fine (like some cylinders are not working): http://www.vems.hu/files/Gachax/v3.3_u004705-2013.11.02-00.48.52_nok.vemslog I updated the firmware and re-soldered some wires in between. Now I'm back with the old firmware and all the wires are checked a 100 times. So it cannot be firmware or those wires (power to ignition coils). It just started to get worse and now it's almost impossible to fire the engine up. I suspect it's ignition coil driving 1st and 6th cylinders. The spark is weak when testing and last time I was able to start the engine only by increasing a dwell time. I tried other ignition outputs and swapped coils, so I'm pretty sure it's that coil also resistance is within specs (at least primary coil as it cannot be measured for secondary). So, I will try to test with some other coils and spark plugs. *(fphil) VT offers a very useful test mode to check ignition link Anyway, '''the question is - is it possible to see that huge difference (the way engine runs) in both logs attached?''' I tried to understand individual_power graphs in log view, but they seem to be very inconsistent in both logs... I was looking at individual_power 2,3,4 as my ignition channels are 0,1,2. But I don't see them being so smooth as in some other example cases I found in forums. '''Is it something wrong with my setup, because it's also inconsistent when the engine was fine running fine?'''
