How to unlock FCA Chrysler Jeep continental 2015+ GPEG2A ECU to use hptuner for tuning? What tool is used?
Here’s the clue.
Original hptuners also can’t unlock gpec2a, need send ecu for unlock.
So does the clone MPM tool.
foxFlash is now able to perform the following operations:
within your documents folder search gpec2a
\Program Files (x86)\FoxFlash Manager\foxflash\DFB Technology\DOCUMENTS\help
When you need unlock some ECU then work with HPTuner, you can contact foxflash technican to get a Unlock file, then do as following, then you can work with the HPTuner.
1. Read all with Foxflash in boot mode, make a full backup.
2. Upload backup file to us.
3. You will recive a unlock file.

It is for bitbox only. Unlock done on int_Flash. Bitbox patch works only for writing by bit box. It is unlocking bootloader, and HP tuner is making it via flash,so cross flashing will brick Ecu.
if you unlock with bit box and try with hp tuners it will brick the ecu.
but some succeeded by trying to update pcm by CDA.
New trasdata will read them.
You can use transdata to unlock them but you have to open the ecu.
Cloning eeprom will take care of immo and Vin.
Flex can read it on boot.
It’s readed in bootmode with Flex (3x1kohm resistor).
The original ktag will do it in boot mode.
