If the MSD coils are plug-in replacements for the stock LS1 coils they will
work with the EC2 as-is. Having said that, I doubt that they would help
with flooded engine problems.
I'm running the Renesis coils on my 20B and not having any problems so
far. The LS1 coils on my 13B Renesis have performed well and I have
not had a flooded engine problem in the last 9 years.
I changed my plugs to iridium type (stock Renesis parts) about 210 hours
ago and they have been wonderful. Never a hint of 'SAG' but I have run
only a few tanks of 100LL during that time.
Proper priming and starting procedures are the keys to easy starting
and avoidance of carbon fouling.

Fouling... again.
Tracy,
Is there a way to economically control the MSD
coils with the EC-2? Lynn is very satisfied with the Mallory Hifire
system in the racing environment. Having this high energy ignition
system in a rotary powered A/C could possibly reduce or eliminate the "sag "
problem and make starting a flooded engine much easier. More spark
energy could also increase HP and/or increase fuel efficiency. Currently
I am ground running my Renesis and have already experienced plug fouling with
carbon. That makes me suspicious that the Mazda ignition system is
marginal at best. Anyone have any comments??

We need not do that anymore because we have the Mallory Hifire or MSD
ignition systems where we can insert over one amp of electrical energy into
the plugs per thousand RPM. The rise times are so short
and voltages are so high, that even a carbon fouled plug fires
We use the NGK R6725-115 plugs, gapped at .010". They have a
retracted gap and fine wire electrodes. The heat range is ice cold. I have
never fouled one. We use a MSD for leading and trailing. Even driving slowly
to the false grid on a cold morning, no problems.
Lynn,
These LS1
replacement coils have 3 times the energy of the stock coils and fire in a
shorter time. Could these be worth testing if Tracy's controller
is compatible?
