questions about replacing the ECM

[amauri]

I'm thinking of replacing my 2022 ECM with the unlocked replacement originally installed on a 2019-21 truck.
FCA p/n 68363277AA is what I plan on purchasing. They show this as being compatible with 2019 - 2022 Cummins 6.7 trucks.

Dirty Diesel in CA offers a Unlock Service, I would have to send them my original ECM and the replacement ECM.
They will copy the files from my 22 ECM to the unlocked 19-21 ECM and send it all back to me.
Once I receive the ECMs back from DD, I would install the 19-21 ECM and load my choice of CCS tune.

Though it doesn't happen very often, I'm concerned with the possibility of losing two ECMs in transit.

What I'm thinking of doing is having my local dealer install and configure the 19-21 ECM for me.
As I understand it, they would load the stock 2022 files and I would end up with an unlocked ECM that I would then be able to tune.

Does that make sense?
Maybe Jimmy07 can offer some insight?



Does this make sense?

You have to @ a member ID if you want to tag them to get their attention. Or send a DM.

Some additional info I've learned about ECM replacement on 2022 - 24 Cummins 6.7 trucks.

EZ-LYNK Auto Agent 3.0 has an option in their "Functions" menu called "Replace and Reprogram"
This allows you to copy files from your original ECM before installing the new ECM and then transferring those files over.
The how-to instructions and video are linked in the Dirty Diesels Customs CA website.

RaceMe also offers a similar way to copy and transfer files between ECMs without sending them in for a bench flash.

- new ECMs are impossible to get from FCA right now, seems like that desirable p/n everybody wants have all been scooped up by tuners.
- used ECMs from salvage yards are selling for as much as FCA sells a new one for.
- China is flooding the market with cheap counterfeit ECM copies on ebay and elsewhere.
- lots of used 2022 ECMs on ebay, some being misrepresented as the 4384696 p/n people are looking for
