As above really. Put the programme on an old WinXP laptop, bought a £9.95 lead off FleaBay, and it all connected fine. Interesting to be able to check the operation of various components. As far as throttle body adjustment is concerned, the display showed 640hPa on cylinders 1 and 3 and 620hPa on cylinder 2. I'm not convinced that this is sufficiently significant to worry about....... unless any of you would advise differently?
Aha! Just seen on the TuneEcu site that difference should not be more than 10hPa. Looks like I may have to try tweaking.....
