I found this site
http://ducatidiag.xooit.com/index.php The guy offers freeware with fuel maps etc for Ducati and Guzzi ECU systems, you just have to source the cables on e-bay or wherever. Has anyone used this system ? It seems almost the same as VDST except it's free

The site is in french so most postings take a bit to figure out, are ducati and Guzzi fuel injection systems the same? You have to register in order to get access but it seems there are maps for most current bikes as well as the ability to do everything the VDST will do. I'm just wondering if anyone else has used it....not sure I want to be the guinea pig!!!
