PWTS Manual & Quick guide UPDATE
Apparantly the first units of the PWTS come without a quick guide so it will be hard for you to figure out how to set it up.
Sorry for this but to print the manual would have delayed the shipment.
The full manual will follow next week. In the meantime you can check the PWGT3RS manual how the TUNING works.
In the attached document who can see how to connect the RF dongle to the wheel in order to make it work. You can also see how to calibrate the shifters or the wheel center.
