Your right Bobby, thats what I=E2=80=99m thinking. A male-female D-sub37 th= at I can plug into the current loom that brings out the CAS inputs, Coil an= d Injector outputs.

The NOP indication is directly linked to RPM - about 6K (Dynon miss r= eads at the same point). But no missing occurs at this point, engine contin= ues smooth.
When the gremlin strikes (all hell breaks loose) it does appear clear= ly 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 e= arths 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 1= 0 gauge wire 36 inches back to battery.
In order to easily get to all electrical systems I opted for a two bu= ss 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 independ= ently back to to battery.

Thanks Steve and Bobby
I kept and ran the injector lines and coil trigger lines independentl= y 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 minimi= se damage to the drive line.

Last night I had the thought of making a DB37 breakout so I can easil= y get a CRO onto and monitor any input/outputs to the EC2.=C2=A0
I=E2=80=99ll do this before next Friday enabling testing of electrica= l systems.

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