It it possible to reflash unlocked pcm from trx to charger

[Fastspeedjohnny]

I?m trying to flash used unlocked pcm from trx to be used with hellcat charger

Only if the part numbers are the same on the PCM and you will need to flash the PCM with FCA software. HPtuners can not change the calibration. If it is a 2019 and up charger it will not work
as you can not change the security code already programed in the PCM

The charger is a 2020 the pcm is already unlocked. But have Trx calibration.so your saying it?s not possible change on a 2020

As it sits no it will not work 2019+ have a 1 time use 4 digit pin code for the immobilizer, if it doesn't match the vehicle it wont start. and you can not change it even with Witech.

Will this cause a crank no start
