My diog tree points to a failed harness connector. Will stuff the harness today.

Checked the ECu pins for signs of contact, all look good with about 50-60 % of pin contact.
Checked the harness side for loose pins, gave a little squeeze from the front side. Same result, Shows RPM on crank to ECU but no PWM output.
Looking at the live data; RPM shows up, requested PWM shows up. No Action at Injector 1 or Injector2 @ box recorder. My guess is that this box should show injector trigger count?
Is that correct?

All other data looks like it should IMHO.

Looks like I had a faulty harness from the beginning. Squeezed the females a bit and it runs.
I am running the tach trigger from the Bosch Hall sender to the VR 1 red wire. Now all of the trims are working.
