This is a used diagnostics tool for Vespa and Piaggio fuel injected scooters. I bought it from ScooterWest this past summer to diagnose an issue and no longer need it. Just plug it into the diagnostic port on the Scooter, then the battery, and then connect the other end into your computer. It includes the card that shows you where to download the software. It worked great to read the error codes, check temperature, and test fans. I also used it to check the idle. See the description below from when I bought it. Asking $200 with Paypal. I'll pay fees and shipping in the continental US.
