Diablo/Pred/etc and Automatics...

Hello all,

Does the Predator/Diablo/etc units do anything with the downshifting behavior of the automatic trans? Let me explain...

I'm not talking about changing RPM upshift points or the 'firmness' of the shifts. What I am wondering is if the programmers can actually change *downshift* behavior.

For my preferences, I'd like the car to be more aggressive in downshifting, maybe with less throttle opening. Seems like I have to really put my foot waaay into it to get a 3-2 or 2-1 downshift... like the car really wants to avoid going down a gear... fuel mileage biasing?

Do any of the reprogrammers address this?

(sorry if this has been rehashed 1,000 times before... I did a few searches and didn't see my question)

Thanks!

I hadn't seen the question either...

It's really more of a day-to-day driveability thing... part-throttle behavior. But it sure would make the car feel a lot snappier if it was a little more eager to downshift without having to go WOT...

Seems like it should be very possible to "tune" downshift behavior if it is all PCM controlled... change the throttle position sensor downshift trigger value from 90% to 70% or something. I'm sure its more complex than that, but you get the idea....
