I think a lot of the comments are overthinking this. To play devils advocate, i will look at this from a warranty aspect. Most of my neighbors who run new or relatively new iron are their own worst enemy. They buy the biggest machine of their favourite colour but always want to 'chip' everything. Trucks, pick-up trucks, combines, tractors, sprayers. Did i miss anything? Then have reliability issues and bitch that warranty doesn't want to cover the cost of repair. As long as the machine is on warranty, it should be 'hands off' unless its regular maintenance. Many years ago i had to deal with customers who did all sorts of crap and then wanted warranty to cover the cost of what they screwed up. 99% of the farmers i know only know how to do basic repairs. That's one reason why they trade regularly. Access to software beyond certain parameters is asking for trouble from a service point of view. Hey, after the warranty is off a machine or engine, who cares if they double the hp and grenade other components. That's their problem and they can factor that cost into their bottom line
