From the factory FK2/FK8 ECUs cannot be programmed over OBDII and must be unlocked ('jailbroken').
An 'Instant Jailbreak' allows your FlashPro to jailbreak your FK2/FK8 ECU in your vehicle without the need to remove the ECU.
You will need a FlashPro and the FlashProManager software installed. It does not matter if the FlashPro is locked to the ECU or not.
