An actual educated question about 2011+ support

[desertsoldier22]

I know this horse has been beaten into the grave but this is a question based on experimentation and I waswondering if it can be implemented.

Tunes are a great thing to have but some of us just want to change gears, has improved shift performance and have our limiters turned off.

I recently have taken my 2011 Charger R/T TCM and transplanted it into a 2010 Chrysler 300C, I then changed the gear parameters using that car. I then installed the TCM back into my car (it works fine and I am seeing the improvements). The TCMs while not having the exact same part number are similar enough to interface with the 2010 PCM.

This leads me to believe that the actual PCM I/O hardware in the new GPEC computers is pretty identical to the older PCMs. Which also leads me to believe that the only roadblock is software or a security co-processor that installed and is acting as a gatekeeper to any programming changes (you probably already know this). With this in mind I ask the following questions.

1. Can you guys give us an update that changes TCM parameters only? To hold us over until actual tunes come out. This aspect alone makes enough of a difference to effect performance drastically. I still think that the PCM is acting as a middleman though in that respect.

2. Can you guys develop a programmable PCM or replaceable mainboard based on the existing hardware with no encryption imebeded. On some cars this has been the only recourse in the past.

3. Or can you wipe the PCM and rewrite a new base programming that replaces the software encryption and all with your own program? I know this would be a huge undertaking considering the systems these modern PCMs control (climate control, can bus devices etc.

I have look over every post and with the exception of a programmable PCM none of the others have been discussed on the web forums.

Thanks for bearing with me

1. maybe...would you (and 1000s of others) pay $389 to just do trans quick adjusts and tire size?

2. Yes, we could modify the existing PCMs to change the bootloader, but it would be expensive and every pcm would have to come here before it could be tuned.

3. See above..

What you changed when you did the shift points was a variant string that lives in the header of the PCM, it is not part of any 'flash' process, as you can see by simply needing to cycle the key once to make it take effect. Hopefully somethings will come to light soon

1. Absolutely...I already own a Trinity, so the investment has been made. Not mention being able to use the gauges would be nice.
There is no other way except the transplant method, and that requires a very trusting friend.

2. Any way of changing the boot loader so it could be tuned with a intune or trinity? That I would pay for even if it was a $1000

3. Ok so the bootloader is seperate hardware...that makes things difficult
