which should help immensely in my cam-sync endeavor
car runs wasted spark, strobed cyl 1 and chalk marked cyl 1 tdc on trigger wheel...FTT of 0 and TDC after trigger of 72 was off, 67 degrees TDC after the trigger with First trigger tooth set to 3 is spot on. This is BMW vanos 60-2 wheel, cyl 1 TDC mark comes around 5-6 teeth to the right of the prim trigger (324 degrees moving counterclockwise from missing tooth)
Found car has a resistor in the coil ground causing grounding errors for the primary trigger when power to coils was activated.
---Fixed. Clean signal back.
Secondary trigger hooked up, also clean reading.
- Attempting to get full sequential running.
- Confirm Ignition/injector orderings.
- Try firing order 3-6-2-4-1-5 (stock is 1-5-3-6-2-4 but cylinder 3&4 TDC is first to pass primary trigger sensor)
--wasted spark will be 3,4-1,6-2,5 (from bottom to top, and repeated)

Injectors are wired such that:
\emph I am very open to suggestions/advice on any glaring issues anyone notices in my config as this is my first foray into this type of thing...
VEMS installed, 60-2 Trigger wheel.
Primary Trigger Sensor: VR
Secondary Trigger : Hall
Had good luck with VR trigger - nice clean signal.
This - until DME Relay was hooked up (which provides power to injectors and coils). When this happened I lost trigger signal.
