That would be awesome! Would your SOTF require a physical dial to change the resistance of some sensor? Or are you hoping for a more graceful approach:)
Just the CM2200, or all Cummins ECM's?
That is an amazing goal to have Jim. Sounds like you have set deliverables and timelines, which is definitely needed for a challenge like this. Please keep the world posted with your progress!

Warning about reading a previously tuned ECM.
Me too. I am assuming those are emoji's that aren't recognized by Chromium.
No platform supports the 2022+ CM2450. Those controllers are locked down with no known security vulnerabilities.
Unfortunately, you will need to find a new tuner for your truck.
Glad to have you back Jim! Hopefully you don't get banned again. Like the new user name;)
I understand your desire to learn to tune your truck yourself (that's what I did with my 2010), but it is quite complicated. You will need to determine all the different parameters that need to be...
There is only one platform available that has the parameters easily accessible in their software to change emissions parameters. For EFI Live, you need to learn how to create a CAX file, and...

Admins, Please delete if not allowed.
Sorry you tried to read the ECM. There are warnings about doing that (same can happen if the truck had been tuned with EFILive and you try to read with HP Tuners). @Jim P may be able to help, but I...
That is good to know Jim. Maybe I should just schedule the recall and see what happens. Though it would suck to lose tuning ability. Are you saying that on some CM2450 controllers, once they have...

There is a good post on the EFILive forum about this. Essentially, once the new OS is flashed on the truck by the dealer, you are done (no way to tune it anymore). It is why I am hesitant to have...
Thanks for the share Jim!
I have tried a SOTF tune, but some transmission parameters were changed that I did not like (would hold 2nd gear until ~2300rpm before doing the 3-4-5 shift super fast). Being able to change tunes...
I have always just used Android but I know there are some features that only work with Windows (not sure which ones).

I would recommend AlfaOBD for this type of change. It is available on Android or Windows. You may need a bypass cable depending on the year.
Jim has posted some good information here:

5500 has the Aisin transmission which has no aftermarket support for tuning. Something else is going on.
Great post Jim. Hopefully people will read this first prior to any posts being made.
