Mark;
It’s great that this has
have resolved the occasional misses for you. It’s
very puzzling to me that my engine (and apparently
many others) has always run smooth at any condition
over about 1500 rpm with the same controller
and the D580 coils. Has this only been an issue with
the P-port?

Do these coils have circuitry installed so as to run on low
voltage? Has anyone tested the various models on a scope to
see the output? Peak voltage and burn time?
Anything used in a car or truck has had every extra penny
removed from it before you see it. It will perform to the
lowest possible standard. A very high percentage will fail
just outside the warrantee period. GM is really good at this.
We raced against Ford Probe owned by a drive line engineer for
GM and were told us that he was nearly alone in his division,
and that drive line vibration problems were solved by
engineers in India.
The instant GM figures out how to run an engine with no
ignition system you will never see one again. GM did not go
out of business because they produced too high a quality
equipment.
Last year I sold my GMC 427 Crewcab towing vehicle for
pennies at our yard sale.. It had its 3rd GM paint job blow
off into the wind. And, it left on a rollback because the 4th
set of Chinese brake lines had vanished in a cloud of rust
dust. GM put on three sets and the American motorcycle museum
put on a set. DID GM care about who I ran into when the brake
lines failed? Not at all. They have two cost curves crossing
on a graph, and when losses from law suites get higher than
savings from Chinese parts, then they will care. But not now
that its Government motors. Your coils were designed by
electrical engineers, Lawyers, you, the elected officials of
the united states, and an army of brainless tree huggers. And
still there is a misfire?
Seems impossible.
But I could be completely wrong.
