Summary of change:
I have diesel truck with 6 cylinders 14liter engine with 450HP at 1500rpm, where i use vems as piggyback only for fuel injection(2 LPG injectors) so vems shares vr sensor with stock ecu. [http://www.vems.hu/files/DamirMuha/diesel /v3.3_n002751-2009.09.07-23.16.23.vemscfg config 1.1.59] ---- '''Trigger''' On crankshaft it has 36+1 trigger wheel (not gap, one more tooth between normal tooth, so 37 teeth altogether, see picture). This is called InputTrigger/ShortGapTrigger (although more teeth, similar strategy as subaru/fiatstilo style => use recent 1.0.x, or wait until it's made to work with 1.1.x sometime after 1.1.59) * You might be to get stable RPM with missing tooth setting. (next trigger tooth=18 ?) * Impossible to get it working with "coil type" trigger setting. No use trying ** if i understand right, advanced filter will filter two teeth(because time beetween two teeth is double less) so that trigger wheel will act as n-1 **Are setings # normal tooth: 16 .. 100% # missing tooth: 125 .. 300% good? *** If i set N-1, then i have very stable rpms(only if i put trigger tooth 0 else 0rpm), but 3 time less(engine idling at 560rpm, vems shows 186rpm and if i put next tooth 9 rpm doesn't rise rpm). And i have altime trigger errors. Tried with advanced filer on/off [http://www.vems.hu/files/DamirMuha/diesel/misingv3.3_n002751-2009.09.08-17.31.28.vemscfg config N-1 1.1.59] *** on coil type, i solved second problem(now all injectors fire), but still have little rpm fluctation. Normaly if i put next trigger tooth 37 have stady readings, but only one injection per crank rotation(i need 2). [http://www.vems.hu/files/DamirMuha/diesel/coilradiv3.3_n002751-2009.09.08-17.27.51.vemscfg config coil type 1.1.59] http://www.vems.hu/files/DamirMuha/diesel/vr2.JPG I put thise settings: firmware 1.1.59 egde:rissing type:coil type '''BAD''' filtering:disable: special trigger: normal number:30 or 32 tried trigger:0 next:15 or 16 and ref table 0 15 0 15 I have to problems. Rpm reading aren't stable(see picture). '''caused by coil-type setting''' - See above http://www.vems.hu/files/DamirMuha/diesel/rpm.JPG And bigger problem. If i set 2injectors, only first one fire * with what divider ? It's good to have the interesting part extracted on your page, You should also publish the full config+tables dump (i can put to fire all injectors at same time, but it's better to fire one at time). If i set 1 injector, first one fire twice faster(what is logical:). * With correct injector divider setting it should be possible to inject properly
