Okay I just started looking at this tonight and here's what I think is interesting right off the bat:TB model predicted throttle angle and effective area tables are different.
I also noticed the Transmission Temp and Ambient temp limiters look like they're raised up out of the way more. That tells me that, as I suspected, they're likely not there for real technical (thermal) reasons.
Also, absolute speed limiter is set to 148 instead of 138 as on the FFS. Probably just product differentiation/marketing, would be my guess, but that's just a guess.
