Ok, so it´s not easy as I tough. Can I buy some sort of machine that can copy a eprom for me? Becaus I´m not so good with eproms. I have a friend that has 2 trim chip on his car, it´s basically a eprom telling the car to use more oxygen and do this ,bla bla bla. We have the same sorts of car modell and everything alike so I want to copy his trim chip becaus a new one cost 80 $. Could this be done without destroying his eprom?
