Thanx for the answers.

I never doubted Tracy's product, I just want to understand its operation.

Numbers (sold and flying) speak for itself.

My question was more to the degree of automation the EC2 provides:

Is it necessary to manually (constantly) re-tune mixture or is this automatic, once the base maps are set? Single Lever - "no need to think about" - operation?

I remember the Speed-Density versus Mass-Airflow discussion from the Mustang 5.0 mags and forums.

I understand that Mass-Airflow is easier to tune/play/aftermarket with, but that Speed-Density is more efficient/precise/expensive??

 

I assume that a (any) controller would be rpm-adjusted by the pilot - hold rpm.

Prop-pitch could also be pilot set (as it is in about every C/S flying)

Prehistoric (Lycontsaurus) school also has you manage mixture - I assume EC2 will do that all by itself, no matter what the throttle position is (within set limits - no way to maintain rpm if pitch is too steep...)

 

About "the" book - well, whatever.... :)

 

About the rest: I wonder when someone is showing PL some "detonation"- parts with Tracy's surviving seals! Probably he will look to the other side and say "I can't see what you talk about!"

There is people in the world that maintain that the sky is green - because they say so!

The weird thing is, sometimes the urge to be right is so strong, they believe it themselves.

Even if you proof these people wrong they will come up with the most fantastic excuses...

 

Had my share of contact with alike people....

 

If I ever get near Ed he better gives me a ride in his bird!

...or I am going to tell it that plug's up, evap-cores and pinched ducts are "green" !

I'm not Tracy but the way I understand it is you don't want this.
Why did Powersport get such poor fuel efficiency against the Lycoming
fly-offs in the RV-8's.
Because there was no option for leaning past max power setting.

I guess you could have a max-power/best-fuel-efficiency switch, but then
again you don't have a single lever. And there would probably be times
when you want something in-between and you're back to the variable
mixture control.

Ed has already answered the CS BS.
