2022 Cummins Support

[Riddick]

Does anyone have an estimate on when/if tuning support will be available for the 22 platform? I currently own a 22 and I'm looking for some emissions friendly tuning support. Can anyone verify if this is in the works? Any info will be greatly appreciated, thank you.

Any updates?

[BYTES]

No news? Pretty silent on this

[Blacky]

EFILive currently has no plans to support editing for the 2022 Cummins.
Cummins have securely locked down their 2022 CM2450B controller to prevent any non-stock tunes from being flashed into it.

The next beta update (due out next week) will allow only stock CM2450B files to be flashed.

Only allow stock 22 Cm2450b files to be flashed or all 19+ 2450bs??

Modified files cannot be flashed because Cummins have locked down the controller with a digital signature that prevents modified files being flashed.

Only on MY2022 tho right? Just how it was worded could be under the impression that all CM2450bs will only allow stock files through efilive after next update. So just wanted to clarify 19-21 support will not be changing.

Yes, that is correct. Nothing changes with the earlier CM2450B controllers.

The earlier CM2450B's have a flaw in the digital digital signature verification so it can be bypassed fairly easily.
Cummins appears to have "fixed" that flaw in the later model-years, preventing the digital signature from being bypassed.
Maybe one day someone will figure out a way around the digital signature, but we are not working on doing that.

WARNING if you get an earlier CM2450B controller (that can currently be flashed with modified tunes) re-flashed at a dealer there is a good chance it will be updated to Cummin's later Boot block version which will lock it down just like the 2022+ model years. You will be unable to re-flash your controller from then on.

Oh wow this sounds fun no support from efi, i can flash 2022 stock no problem the moment i touch anything and try flash 99% and boom failed flash and there goes the truck key goes bye bye wont start… well its been fun then working on dodges

[fr33kst3r]

I have flashed 19-20 Cummins but have not been able to change VIN. Is this function possible, if so, how?

For flashing 2022 CMF (CM2450B) stock files, try this updated version: https://forum.efilive.com/showthread.php?30963-Nov-15-2022-V8-3-31-Beta-Release

Note: Please read the "Known Limitations" #2 on that web page about opening CM2450B 2022 files.

Paul 2022 Can we sniff the data going in to a 2020-2021 that locks the ecm down like 2022 and see where they are changing or adding and reverse engineer this possibly?

Sniffing the bus but won't help. The ECM is locked using a digital signature. The same signing technology that keeps things like bitcoin secure. There is no way to "fool" the digital signature.

No, not the same. More secure.The technique we used for the previous models won't work on the newer models.

If 19-21 can't be read, how does one get a stock ctz file? Can you convert .efd to .ctz?

Most times we can, open a support ticket and attach the *.efd file you want converted.

Is it possible to use a 21 ECM to gain EFI Live support in a '22 Truck ? Or are there additional checksums outside of the ECM that can cause functionality issues with other modules ?

[Bigxrig98]

19-21 ECMS can run 22 truck.

[jwolfe]

19-21 ECMS can run 22 truck.

Do you know what that process should look like ? Can I use a blank/unprogrammed 22 ECM instead ?

[Blacky]

The 2022 ECMs have an updated boot block that enforces a digital signature check that cannot be bypassed.
The 2021 ECMs have a boot block that contained a "bug" that could be exploited to bypass the digital signature - Cummins fixed that bug in the 2022 boot block update.
So no, you can't use 2021 ECM to gain access to a 2022 ECM, the only way would be to change the boot block in the 2022 back to the 2021 boot block, but you can't do that until/unless you supply the correct digital signature (or bypass it, which cannot be done).

Warning: Getting your 2021 ECM flashed at a dealer can update the boot block to the 2022 boot block thus rendering the ECM no longer tunable.

Is there a way to know if the boot block update has been done or not? Will efi allow is to flash it anyway or will it give as an error before commencing? If the flash does begin will the ecm be bricked or will you be able to flash a stock file back in?

[Jim P]

If you have had an OEM calibration update for the CP4 recall, you got a new boot loader. Myself haven't come across one yet that couldn't be tuned still (2019-2021). With some magic you can swap a 2019-2021 ecm into a 2022 and make it tuneable.

If the boot block is locked, the flash will still commence. At the end of the flash when the digital signatures are checked by the ECM and subsequently rejected, the ECM will remain in boot mode. It won't brick the ECM, you just need to flash a stock file with a valid digital signature back in to recover.

You don't create an .efd file. It's a Chrysler flash file that you download from them after paying them a fee and it's encrypted.

Paul, completely unrelated to all this, but could I perhaps pick your brain a bit in pm or something on PPC and Chryslers logic in a cm2200. Been trying to dive into it and its got me all cross eyed on some of the things I've noticed while trying to learn and understand what they got going on in there lol.

[fr33kst3r]

I tried to flash a 2022 ECM with a stock file and received an error" Wrong ECM Type". I received the error when I check for license using the Beta version. So far 19-21 have been free of issues.

How i tried this already put a 2021 ecm with the correct vin on a 22 truck couldnt get it to start

[Bigxrig98]

Takes a bit of playing to get skim happy once its happy theres a decent bit of stuff that needs to be changed in file to get it to run smooth and quiet like 22 cal does. But can confirm it it does work 100% got a 19 ecm in my 22. Needs more tools then efilive & a vin change alone ill say that.

That i am aware that its not just a vin change, what i ask is how were u able to program the key because i had the truck with a technician who has original witech and dealer account we couldnt get the key programed thats why i ask how were u able to start the truck

I am curious as well - what all was involved ?

[Bigxrig98]

You need to have the stock 22 ecm from truck to read the security keys out of, then you have to program the keys back into the older ecm with cummins software as well as change vins in a few different spots. If you have 68rfe truck PI curve will need to be reprogramed with witech also.

[BYTES]

What software you use to read the security key out? Change the vin where? What if i just put the vin on the old 2019-2021 ecm ?

So basically if dealer flashes the 2021 ECM you WILL be locked out or will possibly be locked out?

Possibly locked out - we have heard of it happening (anecdotally) but have not confirmed that it happens.

Is there a way to check if the Boot Signature has been updated without trying to flash the ECM?

[Blacky]

Unfortunately it appears Cummins did not implement some of the OBDII commands correctly that are used to obtain the boot block version number, so unfortunately there is no easy way to know.

[fr33kst3r]

So the option is to use a 19-21 for a 22 Cummins flashed with the calibration and VIN of the 22. Will this work and is there anything else that needs to be programmed to get it to work?

I don't know if that will work. It is not something that EFILive has worked on, tested or explored.

[Bigxrig98]

Bit more to it then that unfortunately. Need few extra things to make security happy etc. If its 68rfe truck will need converter pi curve programmed as well. Any 19-21 file will work as well with enough messing around. my 22 runs efi CSP5.

Are you running one of the two OS that efi live currently supports csp5 on the 5th gens?

[Bigxrig98]

Correct

[got boost?]

Correct

So let me get this straight real quick. You're using OS 52.20.03.00 that is associated with cp4 based calibration ID's on a cp3 truck? Any editing outside of efi live done for cp3 to function correctly? Thank you for your help.

[Bigxrig98]

Using the 19 cal but yes same thing. And yes theres stuff outside of efilive needed to use to full potential on cp3 truck

When you say a few extra things for security, other than the VIN, is it done on the ECM or is it additional programming on another module? Can you shed some light?

[Bigxrig98]

All in ecm programming. To make what the other modules see for “keys” match.

Does the key information need to be extracted from the original ECM? Or the TIPM? Can it be done with EFILive or switch to Witech?

I tried many times can never get the key to work could you help how make it turn on ? 19-21 ecm on a 22

I'm currently working on the same issue. Tried multiple ECMs (19-21) on a 22 and getting a security no start. Have you tried relearning the keys? I think that could be a possibility.

[BYTES]

We tried with Witech and the secret code straight from dealer, same shit wont start

I have 3 19-21 that lose the VIN when installed on the truck. VIN shows all 0's. We try to update the VIN with EFI and shows it was complete but when we double check it, it still shows as all 0's. Hoping we can get this figured out. Do the keys need to be relearned into the new ECM?

[battey914]

I believe the "secret code" cant be obtained from the dealer anymore. Have to have a NAFTA ID to be able to program keys/codes. Ran into it when programming a replacement PCM on a flood truck.

[wesleydsc]

Hi guys.
I need original file from CUMMINS QUICK SERVICE for this vin's:
3C6UR5FL4NG243178

I will try write this files in ECU 2019 for try tuning RAM 2022

I get secret code from dealer and still can not program old ecu in 2022 truck weird as fuck someone has the secret guarded lol

You wiped the keys and relearned both keys using the Key Code? I am about to try this next week on a 22 truck w/ a 20 ECM.

Maybe thats my problem not wiping the old keys

So you put the truck's original VIN in the 20 ecm? Did you finally do it successfully with efi live? I've never heard of "wiping the keys"??? I thought you just reprogrammed them by having them in the truck when doing it???

[fr33kst3r]

I know it's being done. I just don't know how..... yet.

I can leave ecm virgin, anyone with witech can then put vin and learn key
