I doubt they do much of anything, but are there any chinkshit clones of these with ripped roms or any public maps + tools to flash them? I mostly just want to try it because my shift points are terrible and I plan on doing custom exhaust (factory is log manifolds merged into one 4in pipe with one massive cat, sounds like soykaf, and is rusting out anyway). I'm not paying the price of a modern cellphone for a tool artificially limited to one vehicle.
