Last night I had the thought of making a DB37 = breakout so I can easily get a CRO onto and monitor any input/outputs to = the EC2. 


A simple screw = terminal strip may be simpler use for testing. That would allow full = access to the CAS wires to add an external 1k resistor and verify p-p = voltage.

The NOP indication is directly linked to RPM - about 6K = (Dynon miss reads at the same point). But no missing occurs at this = point, engine continues smooth.
When= the gremlin strikes (all hell breaks loose) it does appear clearly = related to load - just before 24=E2=80=9DHg.

Ive never checked the = timing with a light or whats in the EC2 (dumb), just thought I'd = zero=E2=80=99d all parameters in non volatile memory.
I=E2=80=99m going past the hangar today so = will fire her up and read the static timing setting via the = EM3.

As far as Earths. I have a noisy one and a quiet one and one = for the gear pump.
Each has 10 = gauge wire 26 inches back to battery.
Each Earth point is an AN bolt and nut clamping all those = paticular earths lugs either side of the 10 gauge earth lug. All lugs = are soldered.

Power Busses are: Engine, Flight and Gear = (30 amp pump) each fed by 10 gauge wire 36 inches back to = battery.
In order to easily get to = all electrical systems I opted for a two buss blade fuse arrangement. = (The gear power is a 30amp breaker)
This does mean on the engine buss, EC2, EM3, Coils, = Injectors, Pumps, are fed from the same point via 10 gauge wire rather = than the EC2 independently back to to battery.

Thanks Steve and = Bobby
I kept and ran the injector = lines and coil trigger lines independently seperate from each other and = all other wires where possible.
eg. = Coils go to the right and through the firewall. Injectors to the left = and though the firewall.

I do pull the throttle each time the gremlin = strikes trying to minimise damage to the drive line.

Last = night I had the thought of making a DB37 breakout so I can easily get a = CRO onto and monitor any input/outputs to the EC2.
I=E2=80=99ll do this before next Friday = enabling testing of electrical systems.

I=E2=80=99ll check the = CAS signal amplitude and check the injector signals.
I would like to get a video recorder, = recording everything as I always forget to check some parameter each = time I=E2=80=99m testing.

Sort of.  That NOP you are seeing is a = good indication that the ec2/3 has been jolted out of its normal = operating loop and is trying to reboot.  The backfiring is too. =    Electrical noise (probably in the grounding scheme of = electrical wiring layout) is the most likely candidate.
