If I recall correctly, that is the precise range Maurice set the stage I to operate under. I remember something like 14.6:1 at most rpm's, and 13.5:1 at WOT. Am I recalling this correctly? If so, what are the changes made in the 1.1 upgrade?

If I remember correctly as well versino 1.1 saw a slight richening of the mixture in areas as Mazda leaned it out a little in some and a lot in other areas. CZ also included ignition advance in 1.1. Knight Sports does as well...

It looks like they updated it.

Mazda compensates by retarding the timing slightly in the leaned out RPM range with "L" correct?

Yes, but I haven't verified how much.
Maurice said it was something in the 17° IIRC.
I just add it back with the E-Manage.
