I kinda see the rationalization of wanting to protect your software, which is what this is really about. But......once the vehicle is out of warranty, the manufacturer no longer has ANY claim on the vehicle...period. Folks have been re-writing software for computerized vehicles since they first came out in the late '80s. In fact, ALL of the major manufacturers have updated software DAILY for every vehicle they produce, which means they dint get it right to start with. Does "Windows" ring a bell? :help:
A disturbing number of recalls, and TSBs issued by the manufacturers involve software updates, not hardware failures. While the major manufacturers employ some of the brightest programers, there are many more that are smarter, and can re-write software to make it more user-friendly to the consumer, along with improving performance AND fuel mileage. THIS is where the issue with folks digging into code makes the manufacturers quiver, and cry "FOUL!". GM et-al has to provide programing that works in vehicles all over the world. so the same programing for a car in the deserts of Nevada will start and run the same as one in the UP of Michigan. A daunting task, to say the least. But why should the guy in Florida have to be stuck with programing written for -30 degree weather? Why should he not be able to go in and change a few parameters on a fuel map that will provide better fuel economy and performance once the car is out of warranty? What aboot the hot rodders that use later model drivetrains in their '34 Fords? Why can't they eliminate all of the seatbelt interfaces, and wiper motor inputs for the PCM that they don't need?
Why? "Because I built it, and I say YOU can't change ANYTHING!". In Texas, the law states that the vehicle's emissions and safety equipment must match the year of engine manufacture, so, if you install a late model drivetrain/PCM set-up in your '47 Willys yeep, the vehicle MUST pass emissions/safety regs for whatever year the engine is. So...how the hell do you put an airbag on a '47 Willys?
Since 2010, you can't even go to a salvage yard and buy a used PCM and install it in your vehicle, because the security software is already written to the PCM for ONE vehicle ONLY. Installed in any other vehicle, it will instantly FRY the PCM, rendering it useless. So, now that PCM is not gunna work, I'll stick the old one back in and try something else. Not....putting even your ORIGINAL PCM back in the vehicle will automatically render it useless, too. So now you have TWO pos computers, and a dead vehicle. Afaik, the ONLY people able to get the coding/programing to install new PCMs in situations like this are licensed locksmiths. We have a mobile programer that comes to the shop the program/update PCMs in some of the vehicles we work on. They have the licenses to do it, but even they are having more and more trouble getting programing for later model cars from the manufacturers.
As I stated earlier, I doubt seriously that this exemption thing will go thru in favor of the manufacturers. Besides...when's the last time ya seen a friggin JOHN DEERE on street tires rolling down the boulevard on cruize night? :smilie_happy: :mrgreen:
