SCT & the latest ford flash. compatible?

My truck is going in to the dealer for the 30k service and list of recalls (reflash / IC cluster, fuel tank brace, seat back). I'm worried that they will reflash it and my current SCT tune will not work anymore. Someone had mentioned that SCT's tunes do not work on the latest flash. Has anyone experienced this?

Currently, I run the very old 1.20-OR tune. My truck is a Job1 and has never been flashed since purchase. I think the most recent update (before purchase) was the flame-thrower flash. Beyond that, nothing has been done to it. Runs great though.

Can I allow them to reflash it (I'd like the improvements to the cruise control, etc) and just download the newest SCT files for my 9621, or will it really not work at all with the most recent flash?

It's going in tomorrow, and now I'm a little paranoid and not sure what to do.

Thanks guys!

Not sure if you have a choice in the matter as to if they flash it or not and once they do flash it than you cannot go back.

I have a job 1 and had the flash done in december that fixed the cruise control and changes the display to tell me that the truck is in Regen mode...all the time.

I don't like the new flash and am sure that I got better mileage before with the old one and fewer regens. Not sure of compatability of the SCT as I didn't get mine unil June of this year. That being said, my SCT works flawlessly with the new flash.

Thanks for the feedback. I'd read somewhere that the newer flash regens more frequently in an effort to reduce the duration of each regen. I'm sure that doesn't help mileage.

As soon as I get it back, the DPF is going back in the basement, so the regen frequency isn't an issue. Just hoping to get this out of the way so they quit nagging me about recalls, and for the few fixes not relating to regens, like cruise.

Turns out, there is a new flash. If you get it, your SCT tunes will not work. They are still trying to reverse engineer the latest flash. Stay tuned... (pun intended).

Thanks "rXr" for the link!

This flash doesn't seem to be out for us in Canada yet. Myford.ca where i have an accout for my truck says I am all up to date. Hope SCT gets it figured out soon.
