I had this update problem at first, but after a bit of faffing around on the PC interface etc, it worked fine.
I had the same issue with the 300C and the GC SRT8 jeep.
I bough a Maplin 12 volt power unit, for use with the tuner off the car, it works fine.
The USA supplied unit is only 110 volts so is no good here.
You need this kit to update / change the tune versions, however, I think that 9r.30 is the latest and last version. I believe the Predator is now an obsolete Diablo product.
