Re: Do you own it, or not?
A friend of ours is half of Hondata which make and sell alternative engine control chips for R series Hondas to make them hotter making full use of the V-Tech engine. He started out by reverse engineering the chip with no reference to Honda. Now with a formal relationship with Honda racing they get some inside knowledge.
A few years ago he came here to Europe to sell a few to local enthusiasts. One guy put one in his car, went out and bent it. He did not inform his insurance company of the mod first so was not covered. Tough. There's a less on there. In that case he was lucky he only bent the car and nobody else was involved.
Mod a vehicle's software all you want, but your right to then use it with mod, with and without insurance (good luck getting any insurance) is very, very limited.
