This page contains resources related to Yamaha 16bit ECUs... Development work on the TDM900 would not have been possible without the initial discovery work and support of Samios Motorsport(http://www.ecu-flashing.com/) If you're interested in using the Flash Tool, you should first build the adaptor, try reading your ECU and get or develop the RomRaider definitions (I do not have any). Then if everything goes well, you can decide if you want to get a flash/erase license.All the OBD software on this page was designed for a KKL VAG-COM USB OBD cable equipped with a CH340 chipset. Cables that use the FTDI chipset are not recommended and may not work. Flash tool version 4.2 will now allow you to read the 512 bytes of NV Ram data directly from the ECU... Here's a list of the ECUs we've dumped with the Flash tool so far:2B0-8591A-00-5620 2B0-8591A-10-5630 5PS-8591A-00-1280 5PS-8591A-01-1281 5PS-8591A-01-1520
