Thanks CJ i will try that.
I do still have quite a bit of noise in the system, i suspect the grounds are a little insufficient. I have 4 gounds from the MS pins 7, 8+9, to 2A, 2C and 17,18 +19 to 2B, 2D. Swapping over 2C with 2D made it less noisy but it is still quite noisy.
Don't mind the o2 raeding, it is reading voltage out of my narrowband right now.
It wasn't noisy beore the MS, I noticed Joe has slightly different grounds on his harness pinout. I will try a couple of grounds strapped to the back of the head this morning too.
Oh one other thing. When you first power up the car, the coils (cop) buzz for a second and the tach needle spikes to 6000rpm on the dash. But then everything runs smooth.
The weirdness with the coils has been fixed (added a ground to the head from the coils) then 2 additional grounds from the megasquirt to the head and all is fine.
The Fcon freaked out and would lose its **** occasionally with the MS, so the MS is controlling fuel and spark, as a safeguard I have added 20 points to the pnp map in fuel until i get the lc1.
