Quicker Downshifts Question

[Parva]

Greetings,

Can I adjust my AT downshift points? Am using the U7140 w/ the 87 octaine performace tune, traction control off & tire revs adjusted for the size on the car.

On my '05 Mustang V6 4.0L w/ an automatic tranny, I find the downshifts are slower to engage than I would like. Seems the higher the gear I'm in, the more throttle I have to apply. Then, it'll more often than not, drop down 2 gears [pretty aggresively] when I apply a lot of throttle.

What I'd like is to be able to get a quicker downshift when desired. The time I'd like this the most is when doing between 30 to 50 mph to get a quicker response for street acceration. Not looking for WOT adjustments, just "regular" street useage.

Thanks in advance!

I would suggest you find a CMR dealer and go over your goals with him.
They should be able to help.

Hi Mike,

So, are you saying that my Diablo Predator is of no use for the issue of a "slow" AT tranny kickdown without further costs? Is this correct?

Thanks,

Pretty much...downshift changes require some more in depth mods than a simple adjustable parameter in the tool.

Ok, gotcha.
Is there a particular shop in central or south Palm Beach County that you think might have some better experience in this matter? I mean, specifically the downshift rate in an '05 Mustang V6?

Again,
Thanks,
