Diagnostic cables can be purchased from James Portman (rovermems.com) for the Rovers MEMS ECU. These cables use a FTDI chip that converts the RS232 serial communications from the ECU into a low power USB serial communications suitable for PCs. A driver is required to be installed for these cables to be identified by and work properly in Windows.

James sells these directly from the website, secure payment taken via stripe.com and posts using Royal Mail with tracking, James will send you the tracking link once the postage has been arranged

Troubleshooting

It is important that the FTDI drivers are installed correctly. If installed correctly you should have new COM ports appear. On my PC it shows as COM5 and clicking on details shows it as a USB FTDI port.
