Went to the dealer the other day to order a valve cover,not knowing that i had a TSB 140105 to reflash the PCM,basically to update the computer and reset everything,in general if your having issues with your car always consult with your service advisor in regards to any TSB and follow up on them,they will not notify you,only recalls,heres a little video i came across to https://www.youtube.com/watch?v=39IaVoc0EHs
REFLASHING THE PCM
- Thread starter ZSHO
- Start date
Any TSB,technical service bulletin should be addressed and and followed up within there warranty period,if your vehicle is within its warranty period,repair as outlined by the TSB is paid for by the manufacturer,IF THE VEHICLE IS OUT OF WARRANTY THE CUSTOMER IS LIABLE,RESPONSIBLE FOR THE REPAIRS,so basically try to get them addressed before your warranty is up,hope this helps someone.
Had the car at the dealer over a week ago for TSB 140105 replash the PCM,the senior tech is a buddy of mine and informed him that the car has been sluggish for quite a while know,all i have to say is the beast is back,it rips out in second like never before and seems alot faster,the only thing that found upsetting was this morning heard a rattle and found part of the upper steering column loose,any one experience this?thanks.
On the bumpy roads and with the colder weather, plastic console and around the sunroof, it cracks/squeaks...I hate that, everytime it happens a thought that crosses my mind is I paid $50k for this ****, ttt. Never again.
In reference to writing your tune back after having the PCM reflashed, do you have to send your X4 files back to tuner to rewrite the new code so you can upload your tune again?

Only if the strategy code has changed. You should ask the service writer (if you have a good relationship with them), otherwise definitely use the tuner to check your strategy code before uploading a tune file. If the strategy code has changed, send the new code to your tuner for update. Reload the updated tune when you get it.cror1 said:
Are you referring to the 4X tune by Livernois? Z is correct, that is for '10-'12s only. '13+ get some version of the V8 tune.
A little confusing, since the SCT tuner has X3 and X4 devices, so not sure which tuner you are referring to
If the strategy code changes, and you re-upload your tune without updating the code, most likely the car won't run properly, and you will know right away. If so, simply revert back to stock, no problem, and get your tune updated.
It'd be better to have a process to check the strategy code each and every time after your car is at the dealer for service though, just in case.

Good point! Probably not successfully, so to be safe, always check the strategy code with the tuning device before attempting to update the PCM.
You DO have a fallback though in the event of something happening. You can ask your tuner for the right file for the new strategy code! Again, you may be stuck without a usable vehicle if you don't check the strategy code first before reflashing. Maybe only for a short time, but why risk it?
