Unlocked PCM

[doc440]

Can an unlocked PCM for a 2018 6.4 6-speed be re-vinned to use in a 2021 6.4 6-speed?

Not sure, but at this time we dont yet offer support for the 2021 6.4 trucks.

Thanks. It’s for a 6.4 challenger.

[mikel]

No, not gonna make a challenger pcm work in a 2500 truck

I assumed you meant 18 6.4 Ram to 21 6.4 Ram.


Thanks

[doc440]

Haha! No, 18 challenger to 21 challenger.

Additionally, will installing the original PCM in the 18 challenger set the P1400 code?

[mikel]

If the original pcm is not unlocked, there will not be any codes.

Unfortunately my notes show 18-19 5.7/6.4 cars share a pcm and 20-21 5.7/6.4 cars share a different pcm.

Thanks for the info. Nice to know it won’t set the code. Too bad it won’t work in a 2021 model.
