Validate Checksum Fail HPVI3 RAM 3.6L Pentastar

[Engineer]

2015 RAM 1500 V6 3.6L Penastar
Sprintex Supercharger
Unlocked PCM from Diablosport
Sprintex SC Tune from Diablo

The current tune is from Sprintex and is CARB compliant so I need to return to the that tune. I purchased the HPVI3 hoping to clean-up the drivable but messy Sprintex tune.
When doing the initial PCM/TCM read - there is a checksum error which stops the process.

Is it possible to read the existing tune as a starting point and return to that (or flash with my Diablo box)? Maybe there is a lock on the tune?
Does the Diablo PCM unlock cause problems with HP Tuners?

Really hoping that I don't have to get yet another unlocked PCM and start from scratch with a supercharger.

Any help is appreciated....

Thanks Bill -

Ticket: 66485 setup

Fingers crossed there is a solution. The goal has been to use the Sprintex/Diablo (current tune) as the starting point since it is in the ballpark already.

Buying another PCM and starting from scratch is a very expensive and very time consuming path to take.

I am curious how long it typically takes to get a response for issues like this one. Not in a huge hurry, but would like to plan the myriad of things that need to be planned to engage the tuning process.
There are at least a few people (vendors) that I need to coordinate.

For those wondering.....this was resolved on the backend by adding a definition to the database used by the software. I installed the latest beta afterwards and everything seems to be working now.

Hooray. Lets tune.
