tunes and new flash???

ive been reading lately in some posts that when your truck gets "FLASHED" at the dealer your strategy changes. im just wondering if this will affect my tunes or if i need to get them updated by eric before i can reload them???? or if everything will be fine

Yes if you get "flash" your strategy changes and you'll have to have your tunes updated. Also you will have to unlock your box from you truck cause if you don't when you load your new tune and then go back to stock it'll load back your old strategy. Sucks because everytime you get a flash you use one of your 5 unlocks...

I just recently got the new flash to VXCF9DA TQCK0CD. It is a prett good flash. I loaded my VXCF4 tune no problem. Seems to be running even better than VXCF4 on the VXCF4 flash, probably some FICM differences since theoreticaly the TCM and ECM are compeltely the same once re tuned with the sct and only the FICM stays the same. It cranks a little longer and the glow plugs don't stay on as long and set to stock it is down 3 pounds of boost but feels pretty responsive. I am gonna get a tune to match teh VXCF9 from Matt very soon.

Yes I reloaded my old tune that was written for a VXCF4 strategy. I am using the SF3.

I asked this same thing the first time my truck was reflashed and Vivian from DJ's told me do not use any tune that doesn't match your strategy. She then went into all this technical stuff onto the reason why. All I needed to know what don't do it....

XCal2 has to be Unlocked by using SCT updater software...X3, SF3, and Livewire automatically unlock once you Return To Stock. It is hit and miss whether a previous strat code tune will work on a newer strat code....not advisable since some have resulted in a no-start condition.
