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.
