Summary of change:
Volvo 245 with new generation twin VVT volvo T5 engine. VEMS V3.7, twinshield, simens 875cc, volvo 601 coils. We have experienced extreme trigger problems during cranking. Change every singel part inc; V3, Shielded wire VR sensors, 2 different types. Flywheel, 2 different types, one solid billet one and one OEM from -97 850 turbo. What ever we do, there is till always trigger error. Both less primary, and to many primary. Wont even fire IGN coils. We even changed startermotor, and that made the triggerlog much better, but not good enough to start. Tried everyting, dissconnected everyting but VR trigger, still no good trigger. Moved ground to engine. Moved 12v+ supply. Moved the battery from the trunk back to its original place. Tried all kinds of settings and polaritys. Nothing works! http://www.vems.hu/files/ThorbjornEngdahl/T5%20trigger%20problem/1.png Standard trigger wheel brand new sensor http://www.vems.hu/files/ThorbjornEngdahl/T5%20trigger%20problem/7.png The very best we got. Still not good. We got this with very low battery, and changed startermotor. Never seen such a wierd trigger http://www.vems.hu/files/ThorbjornEngdahl/T5%20trigger%20problem/med%2013.4%20vlt.png With jumpercables to antother running car, 13.4 volts http://www.vems.hu/files/ThorbjornEngdahl/T5%20trigger%20problem/Nytt%20hjul.png Billet wheel, New type trigger sensor. All files located here: http://vems.hu/files/ThorbjornEngdahl/T5%20trigger%20problem/ ---- Hello Thorbjorn, I have reviewed your triggerlogs, the log with the standard flywheel looked best but seemed to have swapper VR polarity, could you redo this triggerwheel (stock flywheel if possible), with swapped trigger wires 8-10 seconds cranking without INJ and IGN fuse ? I'll review this new logs we'll work from there. Best regards, Dave Unfortunately the customer chose to return his unit to me. I tried polarity change of both wheels, but I didn't name all the logs. All logs are with only VR connected. No INJ nor IGN connected. Same problem, on all configurations, just varying amount of error.
