Try this link, from JP's site. http://jpl250rs.perso.sfr.fr/download.php
I've downloaded and ordered the cables off fleabay. You need a usb to ODB2 VAG KKL cable, (don't ask me what it means!!!) and the ODB2 to fiat/alfa/lancia cable. Yhis is for the 5AM and 59M ECU's. There's different software for the older ECU's
You install the software, connect to the ecu and copy the ECU info, and send it to the user forum, then JP sends you the licence enableing the TPS reset function.
I haven't done any service yet, have other work to do on the bike first. You can also download a map edit software, and purchase a licence to reflash your ECU, but this is a different ballgame.
