Good luck man, everyone here hated ZDyne due to the simple fact you have to convert to OBD0, if you are already OBD0. They also dont like the fact that there is only 8 tunable RPM's/points with OBD0. I think LHT John is the only one locally who can use/understand/tune ZDyne. Therefore, he runs a monopoly on it. Smart if you ask me but sucks to try to get a retune with him being so busy!
