I continue to have issues with my Xcal2 tune and what I call an unusual shift from 2nd to 3rd. All other shifts are normal...Since the V8 and the V6 (what I have) use the same automatic transmission, I thought I'd ask here rather than in the V6 specific forum.

There has been at least one other user on the SCT forums that has seen the same thing (also V6 automatic, AND same dealer for tunes).

Do any of you notice a "kthunk" sound when the car shifts from 2nd to 3rd? It both sounds and FEELS different. Stock doesn't do this...

I've asked for help from my dealer--it's been a week and a half so far, and the last I heard was that they were "working with a Ford engineer."

I also asked for help from SCT directly---that was on Monday, but so far--they haven't come back with any suggestions or tweaked tunes.

It's apparently not the torque reduction/control---they made me a tune with this restored to "stock" and it still does it, on the shift from 2nd to 3rd.

Does anybody else see this??? I've had my Xcal2 in hand for over 2 weeks now--and it's not living up to my (reasonable) expectations.

 

Looks like it's fixed!!

Thanks to Ryan at SCT for some new tunes. It shifts very well now between all gears, so I think the issue was definately tune related--stock didn't do it, tunes from the dealer did, new tunes from SCT don't. So---it's nice to actually enjoy things.

I'll have to give it some real drive time, but for now--things are looking up!

Still can't smoke the tires from a dead stop...guess it's hard with the stock gears in the auto. Scrming makes it look too easy....hehe

 

HB, could you keep us posted on your results? I have an A/T in mine as well and have been looking to use the XCAL2 with a CAI. Which did you use? Any other headaches? I was going to use BrenSpeed, who, what, where and how much for yours? Any/all info appreciated. Thanks

 

I got my Xcal2 and CAI from JMS. It took getting tunes directly from SCT to get it working correctly on my V6 auto, so interpret that as you wish :angry:

I've been hearing great things about Brenspeed, Bamachips, and Alternative Auto.

The best thing to do is read the forums, read the forums, and read the forums
