12V VR6 coilpack - Ignition outputs working intermetently

I seem to have 2 issues with this EMU Black FW V3 install:

  • when ign outputs “work” I get a spark when using the output test feature but not when cranking (triggers synchronized)
  • now it’s the 2’nd time the outputs stopped working all together , even test feature doesn’t work. Last time they stopped working, I basically gave up thinking the ECU got damaged. Then out of a sudden they came back while I was testing other outputs.

I have lots of experience with other ecu brands but first time with ecu master so just want to confirm how some things work and what’s “normal”.

  1. What’s the proper coil configuration for a stock VR6 coil? It’s a dumb coil, but with built in signal amplifier. It uses 5-12V signal , coil charges while signal is high and discharges on the negative edge. Do I need pull-up resistors, or I’m fine without (i read that they put out 9V in certain configurations).
  2. Are there any known conditions that could cause outputs not to work when using the Test feature? I wired a high impedance injector to simplify troubleshooting and make sure it’s not a coil-pack related issue. All I’m playing with is trigger config and firing order. Do I need to restart the ECU, laptop?
  3. The trigger log only seems to capture a few engine rotations, it stops recording by itself. On one occasion it did record a few seconds of cranking, so is this a feature somewhere? or does it stop automatically because it sees an issue with the triggers? (I have 2 batteries and charger, cranks very fast, on the screen it shows synchronized the entire time)
