Today I installed a diablosport unlocked 2015 5.7L Challenger PCM, sku PCM-CHALV815 for reference. My P2's s/n is 201199323.

:cry: Below are my woeful attempts at getting a predator 2 to tune this:

1. Installed Ignition software version 1.55.30806.16178
2. Connected P2, says updates are available, updated P2 and connected to challenger
3. followed prompts to put car in run and tune on the P2
3. P2 complains: "Calibration needs to be updated Please Update your tuner"
4. Back to Ignition, says there are 6 update files, prompts to hold okay and reboot the P2.
5. P2 is rebooted and Ignition says update successful
6. Back to the challenger, when I hit tune I get "Processing Supersede File Please Wait"
7. "Updating Transmission File Please Wait..."
8. Turn ignition off
9. After a few resetting messages flash on the P2, I get a turn ignition on (just to run) prompt
9. P2 goes to "Clearing DTCs" and says DTCs successfully cleared.
10. P2 buzzes and reads "Vehicle Communications Error"
11. P2 goes to "resetting tuner". Any attempts to tune again start this entire loop again at step 3, where it says calibration data needs to be updated again.

Taking a look at the history log on the p2, I see the below error when the P2 attempts to update the A8 transmissions
[ERROR],ZF8_Security_Access,4901,Failed to generate level 5 Key

Please advise, as currently I am unable to use the P2 to load any tunes.

Any suggestions on how to move forward?

Not hearing back from the forums or support by email. Is there anything I can do with $1000 worth of paperweights?
