CM2200A Cummins Questions

[Chavez91]

Was Cruising through things and noticed that there was a patch for the RSA Security for the CM2200A. Got one sitting here(2011), haven't even tried hooking it up to the V2 yet, but whats the process for reading out the truck? Can we read out the stock file like normal? and then apply the RSA bootloader patch, then flash over the stock/modified tunes that we read off the truck? or do we need to find some other method (like the LML or getting a dealer reflash) for acquiring another stock file that can be flashed in after the RSA patch?

If I can get a read out without the rsa patch, then ill run outside and grab a read off the truck and mail it in, seeing that there isn't calibration support as of yet. Just curious. Haven't really dug into it yet as Ive been busy with the LMLs.

The patch is for the 601 boot block. It fixes the anti tuning boot loader.

I was just reading the "Cummins 6.7L Bootloader RSA Patch User Guide" is all. Don't really know a whole lot about em ATM.

" Supported Vehicles
This guide documents the patching process for:
1. Cummins CM2100A (2007-2010) ECM’s
2. Cummins CM2200A (2010-2012) ECM's (tuning support presently not available) "

That is what I was basing my assumptions off of.

Sorry. You are right. Too late, brain fart. 2100 is what I meant. 2200 you can't read or tune yet.
I hope the fact that its in the manual means its close. I almost fell out of my chair when i read that the first time.

Also, v8 scan will detect a 2011 but can't scan anything yet and no pids are available

We can't get reading working via OBD-II yet

But the Bootloader patch has been developed and tested working here on the CM2200 (so yes we can flash them too), I guess you can see that the CM2200 is in the pipeline given we can get around the anti-tuning stuff.
Before anyone asks on the 2013+ CM2350B, no luck there, the Bully Dog box seems to be a good solution and probably the only option.

[Chavez91]

Ahh... Alright! Sounds good! Hopefully you get it soon!

Good work! On the RSA!

I talked to someone at Ennis this fall at their booth and he said they used the Bully dog to unlock the ecm and then used something else to tune and in some way delete a 13'+ cummins. he said the only way available was to ship the ECM to them, they tune it for 1500.00 and ship it back overnight.

[GMPX]

They (Bully Dog) came up with something better than that, they used to have people send the ECM in but now they have a module that programs via a different CAN port (not via the OBD-II plug) where I guess the anti-tuning checks are not applied, nothing like leaving the door accidentally wide open Cummins. Hats off to Bully Dog on that one, keeps the aftermarket alive.

[Chavez91]

Yeah. They have a $50 module that you can use with the gt tuner that plugs into a plug in the engine bay that is integrated into the flash process. It's a one time use tho. Once you use it and unlock the ecm. It's unlocked. You don't need to use the special box ever again for that truck.

[catman3126]

So then what can we use to do the tuning? Or would it be another bully dog tuner?
