Disc containing 1000's maps

[theflash]

Hi has anyone ever used one of those discs on ebay containing 1000's of maps for kess and other modules, if so do they work I can't see why not so long as the protocol and family match. I can't see a problem if you other please explain, if they do work has anyone got a download link

Thanks eanyone that can help

I wont be the 1st to say dont even think about it,
Hear nothing good about this Disk of untested tunes,
Theres a huge difference between amateur and Professional tune, and amateur tune Break a component on engime,
Maybe to much Torque, or Boost,
New Clutch, Dual mass, Turbo, etc,
is worh the Risk ?
