Rusty,
Below 22-23" MAP, the EC2 advances timing
by 4 degrees plus what you adjust (advance) with Mode
6.
(Actually the EC2 doesn't advance, it only
puts in less retard......still confused?) See page 13 &14 of the
instructions.

Yes, Ed summarized it very
well. Think of the 5.625 degrees as 'Vacuum advance' on the old
distributors.
You're talking about
something other than mode 6 right? If not, I'm more confused than
before. Per the instructions, that's 4 degrees of change, and is
dependent on MAP, not rpm.
Rusty (I stay
confused)
