It's not strictly clearcut, some tuners go above and beyond 'changing a few numbers' and actually change the way the program works, modify subroutines, even add them in blank areas of EEPROM. This will remain the developers property I'm sure (and im sure I recall one competing tuning company in distant past getting into a bit of hot water over it)
I'm also not totally convinced of a clearcut case of copyright/piracy infringement by an original tuner, afterall the remap comes off a car, goes back on the original customers ecu in a modified form, it's very private and software redistribution hasn't occured as the beneficiary is the person who bought the ecu (and as such a license to use software). Even if there is issue to be raised it's on a different level to open and free distribution of said work., and the laws have been so far very kind to people taking copies of things they are entitled to and in some cases even modifying them so im not totally convinced what a genuine tuner does is a sticking point
The discussion of this topic can get very complex very fast, therefore I've always kept it simple - basically 'is what I'm offering my own work'.
If no then you shouldn't.
It's also worth noting an increasing number of remap companies hold patents in tech improvements used on what gets written to the car.
Remaps are the same,its changing some numbers
You think this because what you've seen is limited to exactly this. I change numbers, what numbers and by how much? Fancy doing some math?
I did a Leon yesterday with very decent antituning protection, unlocked the ecu manually and the tuning procedure was a very involved process.
Anyway, opinions will always be divided - though I am surprised it seems a debatable subject when publishing someone elses work is so blatantly wrong.
