DigiDash2 - SS
The DigiDash2-SS Standard System
The DD2-SS is a 240mm diameter F1 Style steering wheel display and Datalogger system. Programmable shift-lights, lap/split times, engine data, warning alarms, speed, rpm and engaged gear displays are positioned exactly where you want them making the DD2-SS ideal for single seat or sports car racing.
The system comes complete with speed, coolant temperature, oil temperature, oil pressure and fuel level sensors, infra-red lap timer receiver, wiring harnesses, 2-axis G-sensors (accelerometers) on-board and professional data analysis software (which includes Video Overlay).
The DD2-SS is fitted with a 3-bolt quick-release hub and spline and can include gear-shift paddles fitted during assembly at the factory for electronic gear-shift systems.
Consisting of a separate datalogger box and steering wheel display, this system is not just for visually displaying real-time information and recording temperatures, pressures, speeds and lap times, but provides the user with a comprehensive, easy to use DigiTools software package that enables you to analyse and improve your performance. You will be able to review your corner speeds, braking points, racing lines as well as monitoring your engine's performance over time. The DD2-SS provides real information that can be intelligently organised and analysed, immediately highlighting areas for improvement.
The system incorporates a host of features normally associated with high-end, expensive logging systems, previously only afforded by professional racing teams.

What can the DD2-SS do?
The SS Display (“SS” stands for single-seater) indicates real time information on all key vehicle parameters and is designed to replace all dashboard instrumentation with a Formula One style race steering wheel.
Programmable alarms allow you to preset alarm levels and leave the task of monitoring temperatures and pressures to the DD2 system, enabling you to get on with the job of driving the vehicle. Programmable shift lights ensure pinpoint gear changes, whilst for bike engines the display can be switched to show engaged gear with a dedicated Neutral input.
With lap information displays including lap number, total elapsed race time and up to 32 split times, the progress for each lap of the circuit is displayed in real time. Lap times are stored for immediate post-race recall on the display unit as well as with the logged data for full analysis using the DigiTools software (supplied as standard). In addition the lateral and longitudinal on-board G-sensors enable automatic plotting of the Track / Sprint /Hill Climb Maps for each individual lap, providing an immediate visual reference of data combined with actual track position. The standard DD2-SS Datalogger incorporates 17.3Mb of memory for recording data giving up to 6 hours recording time at a 10Hz sampling rate, which can be increased to 20Hz (samples per second) should the user so desire.
The Standard Datalogger incorporates 13 standard channels, namely:-
- Coolant Temp.
- Oil Temperature
- Oil Pressure
- Fuel Pressure
- Fuel Level
- Battery Voltage
- Lateral G
- Longitudinal G
- Distance (metres)
The on-board G-sensors show both lateral and longitudinal forces for evaluating driver performance. Data from the lateral accelerometers can also be used for: drawing the g-sensor derived track map; optimising vehicle cornering grip; determining tyre slip angles; shock and spring behaviour and understeer / oversteer characteristics. The longitudinal accelerometer can be used for: track mapping; measuring braking forces; showing when the driver is coasting; optimising gear/rear end selection and clutch performance.
The SS Display can be used in conjunction with the PRO+ datalogger which has larger memory capacity (64Mb) for up to 24 hours data recording and 4 additional 0-5v channels. A 5v module is supplied providing separate +5v supply and grounds should they be required to power each sensor independently, making installation very easy. These additional channels can be used to record data on any parameter, examples including throttle position, steering angle, exhaust gas temperature, tyre temperature and suspension travel to name but a few.
The DD2-SS Display unit incorporates dedicated displays for real time indication of these channels as follows:
- Turbo Boost
- Lambda (Air / Fuel Ratio)
- Front Brake Pressure
- Rear Brake Pressure
- Brake Bias
The DigiTools software has mathematical channels for calibration and display of all types of sensors that have a 0-5v output.
Expandable up to 16 extra analogue channels and 4 extra wheel speed inputs
The DD2-PRO+ is fully expandable should more channels be required using Sensor Expansion Modules. These modules are available separately and are fitted in-line on the CANbus link, each adding 8 analogue channels and 2 wheel speed inputs.
In addition to the large number of standard channels, 2 expansion modules can be added to the system providing up to 16 additional analogue channels and 4 extra wheel speed inputs.
Additional Software Tools included as Standard
The DigiTools software includes a facility for engine analysis. This presents a plot of engine power and torque similar to that which you would get from a rolling road session. These curves are calculated from the longitudinal G, speed and RPM data throughout the data session.
The maximum power and torque recorded is calculated at each RPM point and these maxima are plotted. So, only time spent at full throttle is relevant to this plot.Data plots can be plotted and overlaid for comparison enabling you to compare BHP and Torque curves pre and post modification or changes to the engine.
Sensor System Check
The Sensor System Check Tool can be used for checking the status of all connected sensors and their real-time values on one screen, as shown on the left.
Virtual Data Display (Dyno Mode)
Engine data can be viewed in real time when the DD2 Datalogger is connected to a Laptop computer, or a previously saved data file can be loaded and played back in the easily recognisable format of analogue dials.
Video Overlay (1)
The video overlay facility allows you to overlay your race data, track map, lap position and company logos onto the original video stream. The data can then be saved to a separate file for visual analysis, posting onto your website or for future reference.
Selecting an individual lap within the video allows you to select the track map and plot the vehicle position around that lap. The video can be advanced frame by frame and manually synchronised with the corresponding lap data.
Video Overlay (2)
A second video file can be loaded into the Video B section and the same process used for synchronising another data set to the video.
The videos can then be played together by clicking the play button in the Video A&B box at the bottom of the video window. You can then compare the video from two laps or video sources side by side.
Video Overlay (3)
The Display Mode box allows you to put a scaled version of the video into another window or monitor, or a saved video and data file can be played back using a windows compatible media player.
The Video overlay facility thus allows a visual reference for the comparison of lap times or drivers and is a very useful method of improving car or driver performance.
The video overlay software is included free with the DD2 system. All you need is a suitable, inexpensive video camera to record your progress around the circuit.
Please note that the processing required for some video codecs is very high and MPEG2 is recommended as the video source file type.
A 5Hz GPS receiver can be purchased separately and provides very accurate speed and positional data. This eliminates the need for a wheel speed sensor and as a result the system can be used effectively on cars, bikes and boats alike.
Highly accurate vehicle speed is generated and displayed using the GPS satellite data and enables very accurate track position data (approximately 3m resolution) so that individual lines through corners can be plotted and compared.
The GPS receiver also eliminates the requirement for a trackside infra-red beacon for lap timing and enables rally stage routes to be plotted and analysed.
In addition to the standard displays, using the GPS receiver provides information on the display unit including: latitude; longitude; altitude; GPS speed; heading and UTC date and time.
Factory Fit Options
The DD2-SS is fitted as standard with a 3-bolt pattern quick release hub and spline. Alternative 3-bolt hubs supplied by the customer can be fitted on request during factory assembly.
Quick-shift paddles (Pro-shift type) for use with electronic gear-shift systems can be fitted as required.
