That’s looks to be a Vehicle data file  for the VECU which does not determine engine HP.  The VECU and engine ecm (EECU) both have various software part numbers for vechicle type and options and engine type. Then there is the data files that go ontop of the software that determine exact things like VIN number and engine serial number and horsepower. A engine data file for a 2005 AC 460P (480 HP) would be 1MS5173P9 . The “P” number on the end determines HP , a P7 would be 400 HP and a P8 would be 427 HP. This is not labeled on the engine ECM . The software level might be on the ECM but never the data file.

I have to ask the dealer for this software and updated. 

is 4.33 ratio good for the uphill or 3.7 or 3.9 with heavy load 65T

I had a buddy pull up that VIN it it is a 460P with 480 HP. It came that way from the factory. Both the VECU and EECU both have software updates for them . The VECU is at Step12 and can be flashed to 12B . The EECU is at Step4 and can be reflashed to Step5 . This can help with turbo lag and poor throttle response. The 4.33 gears would be good for heavy hauling I would thing . The dealership has to do the software updates
