Summary of change:
'''SimpleTrigger problem''' Two cars with 4 cylinder simple trigger setups experience problems with stumbling in the 1500-2000rpm range. First car specificiations: *Firmware 1.1.78 *Simple trigger with 1GT101. Second car specifications: *Firmware 1.1.80 *Simple trigger with 1GT101. I have posted a log and an idle triggerlog from one of the cars here: http://www.vems.hu/files/MembersPage/JorgenKarlsson/SimpleTrigger/v3.3_n002404-2010-11-04-15.52.29.zip Very noticable stumbles occur between 3.03 and 3.06s. I found the bad injector phase setup after taking the log but correcting it did not change anything. '''What should we watch in the log ?''' * We started benchtesting. * we didn't notice anything noteworthy so far: ** injection length, ignition advance and dwell seems to be good so far. * we're continuing testing. ---- I´ve also experienced this with a 4cyl Porsche 911 in Gävle running Simple Trigger, spent a couple of hours driving on the road try to work things out but couldnt anything out of it. It runs as the wind over 2000rpm´s. Firmware 1.1.81 - Can probably post a log tonight. Erik Englund. '''Is that also with HALL-dirac filtering?''' vemscfg or vemslog ? --- We could '''reproduce the problem with invalid setup only''': * VR trigger (~50 usec pulses after LM1815) * and HALL-dirac filtering enabled; Note that validate warned about it. '''With proper HALL signal, max 24 teeth (and signal stable for min 25% after the chosen edge), we could not reproduce the missing spark'''. It behaved well in all tests so far. Note2: *If we disable hall-dirac filter in primary trigger settings the ignition seems good. * '''Can you disable HALL-dirac filtering and see if the occasionally missing spark goes away ?''' * '''what is the duty % of the primtrig HALL signal ?''' (eg. 20% high 80% low ? ) * '''Erik do you use Hall-dirac filter too?'''
