I want to edit my own software for a OBD II DME E.C.U. I've only been able to find software from http://www.bonnevillemotorwerks.com/ to edit an M3 computer. ANyone know of anyone else? I would like to be able to run this software on a laptop and use a special connector kinda like the shark injector to connect to the car to load and backup the software, first is this possible? Second where can I get this kinda connector? Third can I modify a shark injector to load my own software? If I can't do this through the engine port where can I get an EPROM programmer with chips and accessories? Hopefully someone can help.
