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!
I have config and trigger logs, were do i upload? Dont remember how thos site works.
