What was causing it?

--------------------
Don't know exactly. Added additional filtering on the circuit board :
1000pf capacitors were added to:
All fuel injector signals
All ignition control signals
RX input
TX output
47uf, 16V tantalum were added to each processor
Pin 8 of connector is now grounded.
Pin 28 of connector is now grounded.

Thanks Al,
I was wondering if it had anything to do with how the cables were
routed, or their length. I guess that's indeterminate but the noise
was getting in there from somewhere. I hope you really have it fixed
as those kinds of problems are a real pain. I was having an issue with
noise on my EM2 display and that went away with some extra filters that
Tracy suggested. I don't really know why my unit was more sensitive
than most either.
