Ernest- It only has to know whether you are in 3rd or not, so some kind of microswitch, I guess. Seems like it was 3000 rpm and WOT in all the gears but 3rd, where it was 4000 rpm. Forget where I found that. 5.2 US F355s have a temperature sensor that tells the bypass when to open.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
