Just bought it for an upcoming enduro so giving it a test to get used to it - think I didn't get the track learning for the alternate layout quite right in this race but it seems better on the GP layout that was already on the device Another driver at the track showed me how to set it up for rentals, this is what you need: - Mychron ball head attachment: ebay.co.uk/itm/404758270392 (screws onto the back of the Mychron) - Mount shaft: ebay.co.uk/itm/143619524034 (attaches to the ball head at the back of the Mychron) - 1" Ball threaded post: ebay.co.uk/itm/134424449996 (screws into the clamp & connects to the mount shaft) - Steering wheel clamp: ebay.co.uk/itm/403223055780 (clamps onto the steering wheel) - Back up tether if clamp fails: ebay.co.uk/itm/334860734994 (need to use a keyring loop that's less than 1" on the Mychron ball head attachment with the tether looped through it) It works without the RPM lead plugged in but apparently you want to enter Debug/Demo mode and follow these settings first: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Uzzb8wbxNZY.html. I've left them both set to on and it all works as i'd hoped. You can see the mount a little better on the wheel here: imgur.com/a/7Xg4R48
