Jeep Grand Cherokee 2009 SRT8

[ReimundRichter]

predator part no. 185152
predator revision v.9r20l
2009 Jeep GC SRT8

After I had my Jeep in the shop the other day; my predator gives me an error message:
your calibration is 68004314AD and it is not supported. We need to downgrade to 68004314AC......

please help.

either update to the latest 9r29l or, let it do the calibration downgrade using DSDownloader.
