Bill,
I have one of the early aquare boxes, at that time I did have to request a special tubo model. So Tracy must have changed it after you bought yours.

Tracy,
Not that I need or want to waste bins with unused manifold pressures, but is that something that you program into the EC-2 if it is going to be used with a turbo? My unit is the rectangular one bought in Oct 2005, and upgraded in Oct 2007. it only goes up to 41.8 inches of pressure in the top bin.???

All EC2/3s in the rectangular box (past 8 years or so) use 2 BAR MAP sensors which work up to 60" Hg MP.

Dave,
The top bin, +127, on my EC-2 is 41.8 inches of manifold pressure. Does yours go higher?
I just figured that Tracy had something in mind when he set those limits. What does the EC-2 do when you go outside its limits? Does it keep everything the same as the last time it saw an instruction?
I have no intention of boosting my setup and I am roughly at sea level, (55 Ft ), so with ram air, I might be able to see 31 inches. The rest I will never use.
You are welcome to borrow them if you like. :>)

I have no knowledge of boosted rotary engines. It is a fad. It will go away.
LOL, I have no knowledge either. But that is a different matter.
Thanks for the detailed reply, as expected, only I can choose my level of boost and no one has the magic number of when I will run into problems with detonation. And who am I kidding by trying to push the limit. Inching up the power... If 45 inches is no problem, then 46" is going to be OK...
Unfortunately, having "a problem" will mean an engine re-build if not another landing on a road. So I must set an arbitrary limit and stick to it....
(drone voice of Homer Simpson): Eight Hundred horse power..
.. No, stick to the boost limit....
...Eight Hundred horse power...
.. This is an airplane, we are not safely on the ground...
..Eight Hundred horse power...
.. Stay away from the light, do not go into the light!
45 inches MAP. That is my final word, That is law.
