hellcat programming

ya..Im afraid we need a bit more info on whats happening??..you shouldnt ever need to program the ECM. BTW, my 18 HCWB has over 2.25 million lines of code,(literally) so good luck there.
Im not even sure a dealer can program one..they are plug 'n play, factory sealed lil slices of $$, unless you are swapping in a hacked unit (ie: an unlocked one with a tune/tunable)..even still, these are already programed.
The best a dealer can do is "flash" it, sorta like a factory reboot of sorts, like a forced update for modifications, FSB updates, new components, etc. and yes, during certain dealer services, the ECM will 'communicate' with dodge, nothing new there, all manfs no do things this way.
