As I understand it Dave is working directly with HP Tuners to convert the factory ECU. As far as how they are doing that, I cant be of much help. That is outside my area of expertise. Dave at Werks has always been good about responding to any questions. Hit him up or give HP Tuners a call.Well opinions about what tuning software to run aside, I am still interested in learning about the process to convert the car to work with HP Tuners. Is it still the factory ECU or is it a entirely new ECU that is compatible with HPT?
