Subject: [FlyRotary] Re: Turbo boost
limits in the EC2
Ken Welter told me that it works for him, however I haven't
heard back from him. I don't know if there is an easy way to confirm this. Any
volunteers?
The other thing we have to ask is
what ignition controller is Ken using? If he's not using Tracy's
then all bets are off. Mazda times these plugs differently, but I'm
pretty sure that Tracy times them the same. Turning off the trailing
plugs with an EC-2 might not do a thing, or it might work better. I
just don't know.
Tracy already has a timing advance feature
(mode 6), that can be used as a timing retard of 4 degrees at whatever MAP
setting you want. I'm not sure that's enough change though.
If there's going to be a new feature, why not make something more along the
lines of a significant timing retard that happens at a set
MAP. This would stop detonation, as well as notify
you via reduced power that you had crossed the
line.

flight)
Mode 6
went away Rusty. The EC2 now has a turbo boost retard built in that
linearly retards timing between 32 to 60" Hg. Nominal timing is 13 deg
BTDC by the time it reaches 60" MAP. This is to avoid
detonation.

too)
