downloadable car tuning software
Download the .exe file below to your computer and you will be able to do a read and upload the modified file to your car using the Peter James Tuning handheld device. Without this software the unit will not work so you need to download it before it will work.
IMPORTANT: This is a Windows-based software package, as ECUs don't communicate with Macs. So you will need to have a Windows-based computer (Windows 7+). We have heard it will work on Mac simulated Windows, but we can't guarantee it. It will only need to be used for the send and receive - once the Powergate or Bluefin are programmed, there's no need to worry about it again.
