FormulaFlash user report:
Dodge RAM 2019 5.7 with GPEC2A ECM.
Read ECM in boot mode.
Tuner unlock with Formula Flash.
Use formulaflash to perform an unlock, and then program it using HP Tuners.
The tuner performed the unlock patch manually for him, and he only applied the formula; however, formula flash does perform the checksum.
It is good for unlocking E90 GM and GPEC2A Jeep/Dodge units.
