If you count 914s as a variety of Type 4, didn't the late ones get 5 
pin TVSs? Besides, you want a 2L system, not a 1.6 or 1.7L system.

I seriously doubt that it's reasonable to argue that there's not much 
calibration that takes place in the brain. If that were true, Bosch 
could have made many fewer versions of the brains.

I'm aware of a problem some of our cars have in 4th gear at 25-30 
mi/hr, is that one of the transition problems you're thinking about? 
I'm not aware of another one, but I may just not be as aware as some 
of the rest of you.
