1. Safety Information
Thank you for purchasing the Ascher Racing F64-SC V3 steering wheel. Please read the manual carefully
before installing and using the product.
1.1. Intended Use
The steering wheel is designed to be used in a competitive sim racing environment for indoor use only
and connects wirelessly to a Simucube.
Please note the following general safety aspects:
 The device must not be exposed to rain or humidity to avoid the risk of fire and electric shock.
 Do not operate or store the device outside of room temperature, 15°C to 35°C
 We strongly advise you not to drive a vehicle immediately after driving a racing simulation.
 This product is not intended for children under the age of 15 years.
 Contains small pieces – danger of swallowing!
 Extended periods of driving a simulation may cause health risks. Take a break of 5 minutes
every 20 minutes and do not exceed 2 hours of total driving time per day.
 Keep hair, clothing and jewelry away from the product when in use.
 Only one person may use the product at any given time. Keep other persons away from the
product when in use.
 Do not disassemble the product beyond what is described in this product manual.
 Do not apply excessive force, bend or pull on the wireless antenna.
 Make sure the steering wheel is mounted securely to your wheel base and screws are
tightened properly before use.
 Do not leave the device exposed to a heat source or in a high-temperature location, such as in
the sun in an unattended vehicle. To prevent the possibility of damage, remove the device
from the vehicle or store it out of direct sunlight.
1.2. Battery Warnings
A rechargeable lithium polymer battery is used in this device. If these guidelines are not followed,
batteries may experience a shortened life span or may present a risk of damage to the device, fire,
chemical burn, electrolyte leak, and/ or injury.

5. Quick Release Mounting Options
The steering wheel offers a standard M5 threaded, 70mm bolt pattern in order to mount a Quick
Release or steering column. There are several possible mounting options for all common QRs shown
below. Adapters or QRs are not part of the scope of supply and have to be purchased separately.
5.1. SC2 SQR WHEEL SIDE – Simucube Adapter
5.2. SC2 SQR WHEEL SIDE – Ascher Racing SQR Adapter
5.3. 70mm bolt pattern Quick Release – outside mounting
Standard 70mm bolt pattern Quick Releases with non-threaded through holes (e.g. Q1R 70mm wheel
side) can be mounted as follows. QRs with threaded through holes can be mounted similarly by using
captive screws (section with a reduced shaft diameter) instead.

5.4. 70mm bolt pattern Quick Release – inside mounting
QRs with either M5 threaded blind holes or other features preventing from conventional mounting
can be attached from the inside of the wheel casing. Captive screws are required to bypass the thread
of the casing.
First open the steering wheel by removing all (7) M4 screws on the frontplate. Unplug paddle shifters
and clutches in order to separate the casing from the frontplate assembly. Screw-in (5) captive screws
into the casing from the inside completely past their thread engagement. Then mount the QR by
turning each captive screw for only half a turn in a circular pattern until both opposing surfaces are
touching. Plug-in cables, reassemble the steering wheel and make sure to not squeeze any cables.

6. Getting Started
6.1. First Wireless Connection – Pairing
The steering wheel can only be paired (or connected manually) during the first 11s after being switched
on. During this time, the left green LED blinks quickly – a successful connection is visualized by 3 slow
green blinks.
1. open True Drive / Wireless Wheels Tab
2. (Automatic connection mode: Connect to previously connected wheel)
3. switch ON steering wheel
4. double click Ascher Racing F64 V3

6.2. Normal Operation
First switch ON the Simucube wheel base and then the wireless wheel. If step 2 (automatic connection
mode) is enabled the wheel will connect automatically.
A successful connection is indicated by:
 green connection LED blinks 3 times
 Simucube plays a beep sound (if audible notifications are enabled)
 steering wheel shows up in the True Drive overview tab
The wheel can also be connected by using the paddle shifters in case it’s already switched ON:
 pull both shifters to connect immediately
 pull both shifters for 5s to disconnect
Automatic disconnect: The wheel will disconnect automatically after 1h of inactivity to safe energy in
sleep mode. Activity is monitored by the following conditions:
 turning the wheel for more than 10°
 FFB effects in use
 pushing any button on the wireless wheel
6.3. Configure Analog Inputs
Both analog paddles can be either set-up as individual axis (e.g. throttle and brake) or as combined
axis, called dual clutch. This mode compares the output of both axis and uses the momentarily greater
value. Additionally, one clutch is defined as master (m) - the other one as slave (s) with scaled down
output.
 master: 100% physical movement = 100% output
 slave: 100% physical movement = bite-point setting, e.g. 50% output
If the bite-point is set to 100%, both clutches can be used equally.
Dual clutch functionality offers several advantages; the desired bite-point can be reached:
 immediately, within milli seconds (by letting go the master and keeping the slave clutch pulled)
 precisely, adjust the value up to 0.1% precision
 repeatedly, the exact same value every single time
