I always saw the ability to remap diesels analogous to overclocking your cpu. CPU's are sold at set clock speeds and then they are tested for the capability to run at a given speed then sent off to sell. But the same procedure is effectively used for all cpu's (you get chanegs in tehcnology e.g. 65nm to 45nm etc).

They only reason to do this is to protect their high end range, it's cheaper to have one factory making one cpu then sleeing it at a clock it's stable at. Yet you are usually fully able to change the speed the cpu will run at load with all the other components in PC with a 20% overclock being achievable usually in 2 mins and no need for testing. I have 2.8ghz set to run at 4GHz which money couldn't buy.

And it's ashame that the car industry doesn't allow access without special software/cables to the appropriate chips. Perhaps the car enthusiast industry is smaller (due to high cost) compared to the computer industry, though I reckon you could get a decent car for the money I spent on my pc (2k-ish). Computer enthusiasts are usually willing to buy higher end then overclock.

Sorry to be off topic.
