Not certain I have the correct answer. But,
at one time there were two versions of the EC2 – one for N/A and one for
Turbo. I had the turbo version for a while thinking I might install a turbo
(but decided against it).
I suspect that Tracy may have combined the two and just sets
some parameters differently depending on whether the turbo on switch is set or
not. Another possibility is that the Manifold pressure range with a turbo and
non-turbo were different. The turbo had a broader manifold pressure bin than
the N/A – so any reading of Manifold pressure off the MAP bins could be
adjusted depending on whether you have a turbo or not.
I personally found the Turbo version
easier to tune because the manifold pressure bins were wider than on the N/A
EC2.
Some day Tracy
will come down off the mountain {:>) – I mean we have entered
Hurricane season and I’m certain Tracy
would not want to be away from Florida
during that period {:>)

Perhaps this is better directed at Tracy, however, with the
wealth of collective wisdom on this site I will throw it into the pit.
What does the "turbo on switch" on
the EC2 do? IIRC, in the manual it shows it to be either on or of (a
1 or a 0). I ask cuz since I installed my turbo a few weeks ago my
engine is running better than ever. Smoother, more consistently, easier
and more predictable starts etc. Just curios if perhaps I am
figuring out lots of other stuff at about the same time I installed the turbo
or what.
Oh....and the power...even with just three lbs
of boost. Pretty impressive.
Carry on.
