Summary of change:
Cylinder numbering and firing order are confirmed as correct. I would definitely write this down too. '''Don't expect anyone to review your setup without the basic information.''' '''Fill in these''' - let's make this clear: you're most likely on your without this information publish firmware info * Firmware 1.0.38 * and config (mcd, mct). Config updated here: MembersPage/PeepPaadam/Config Firing order : 1-3-7-2-6-5-4-8 || '''cyl''' || '''ignch''' || '''EC36pin..''' || || 1 || 0 || 35 || || 2 || 1 || 33 || || 3 || 2 || 34 || || 4 || 3 || 36 || || 5 || 4 || 11 || || 6 || 5 || 12 || || 7 || 6 || 24 || || 8 || 7 || 10 || Without camsync, some trick is needed to drive COP (eg. ign_dualout). The reasonable wiring is that ignch1 and 0 drive cylinders 360 crankdegree apart. ignch3 and 2 also, etc... Confirm this: all outputs are logiclevel (0 IGBT inside ECU). Logiclevel outputs pull to GND (0V) when inactive, so when you measure DC voltage with DVM, from 5V as base, you read -5V * Wiring is separate, i.e. every ign output is to one coil respectavely, also I wired separate +12v supply and grounds for them. * Switched +12V to coils, they are fused (two banks, 15 amps each) and grounds from the engine. Signal wires come separately from VEMS to each COP. Car runs ONLY on primary trigger which is stock 100-1 tooth wheel on the flywheel and I don't have cam sync. I fire COPs sequentially and car starts ok every time, but some cylinders don't work on low (below 1500) rpms. I tried to fire COPs in pairs, as wasted spark, but it did not make any difference. Note that I fired BMW m50 engine COPs also sequentially by using just stock 60-2 trigger wheel, same low-rpm problem. The engine runs, but high dwell (3 .. 3.5 msec ?) was needed. * Im worried about the little voltage (almost none) from VEMS. ** what outputs ? ** what conditions ? ** what's connected ? ** measured how ? '''A:''' I measured all logic level ign outputs and nothing was connected at that time. Used DVM in usual DC mode and it read 1 volt on ign. event. As Marcell said, it's ok.
