What do I need to start open source tuning? You need Windows XP, Windows Vista, or Windows 7 operating system on a laptop. They both replace the ROM file inside the ecu.
There is no difference between a Accessport map and a open source map. Also discrepancies in tuning have been reported by tuners to find new variables inside the ecu that may go undefined. It is often more powerful than other tuning methods because the maps and definitions are updated by the community. There are also a large number of tuners around the country that will tune via open source. There are off the shelf maps available from businesses such as XPT Tuning or Torqued Performance. It is a cost effective method of tuning your car. De difference is that you use your own laptop and a Tactrix cable to flash the maps on your ECU. Open source tuning works exactly like Accessport Tuning.
I decided to put together, all in one place everything you need to go open source.
