Hello,

Just updated my PCM with new service bulletin from Chrysler but the Trinity wants to restore old parameters to PCM.
Is this normal?

Before service bulletin updates... I restored the vehicle with "Original Backup" using the Trinity.

The PCM was updated with new service bulletin calibration flash.

After everything was completed... I connected the Trinity to the OBD II connector just to see if the Trinity would
respond the the new updates and got a message
"The new PCM part number is not compatible with the previous PCM part numbers would you like to restore?"

I'm trying to create a new Original Backup on my Trinity so I can send to my tuner.



Any suggestions?

Update:

I went to Troubleshoot > Force Calibration Update:

Message received: Feature not available for cal: 68212721AH

you have to agree to the downgrade request then use dsdownloader to get the file it is requesting by letting it connect to the tool and clicking the calibration updater button.

Thanks

Hi Mike,

I downgraded to the old Calibration ID on the Trinity.
then, I connected the Trinity to my PC for Calibration Update... (was successful)

then, connected the Trinity to vehicle and get at message " Voltage too low"

- I'm currently in the process of recharging my batter to meet the Trinity's voltage requirements.


I also connected the VSI 2534 to verify that the new PCM Calibrations from Chrysler Tech Authority were not change, but they were.

Am I still dealing with the old PCM parameters?
The old Calibration ID has corrupt algorithms that has very bad performance and tuning is not helping at all... this is why I have upgraded
to the Calibration ID: 68212721AH but now I don't have it.

From my understanding Diablosport is working on the new Calibration ID: 68212721AH
Chrysler service bulletin * Number: 18-033-17 REV. A * Group: Vehicle Performance * Models: 2013 - 2015 Dodge Challenger/Charger/Chrysler 300

How long before the new updates?

we're looking into this.

Awesome!

Thanks Mike.

Interesting, I had the same basic message on my Chrysler 300 SRT 6.4 that I had to go from an AF level back to an AC level to program the car with the 93 octane tune. That also required updating the Trinity T1000 back on the computer again before my PCM would accept the tune. My Trinity was a refurbished unit that was updated in May of 2017 so it should have been up to date with my 2014 Chrysler. This kind of seems like going backwards to accomplish the performance upgrade that I was wanting.
