The GPS enabled DL2 data logger features integrated accelerometers and many input/output options, making it individually a very capable data/testing system. Alternatively, it can be incorporated into a more complex system with our SPEEDBOX products.
The DL2's powerful processing allows real-time calculations on live data e.g. comparing all 4 wheel speeds to show spin and braking lockup. These calculations can be displayed live on a DASH4PRO display or logged for later analysis.
The DL2 industrial data logger is designed as the perfect partner to the SPEEDBOX MINI range of testing products. The stackable cases and aligned data ports allow for simple connections and easy mounting for the system.
The D-type data connections allow for reliable connections that are quick and easy to populate without the specialist tools associated with micro miniature connector systems. Connections maintained by the secure thumb screws ensure robust connections.

Increades speed and position accuracy, with higher GPS resolution. Download corrections from the internet with advanced PPP mode.
The 20Hz GPS option for the DL2 is quite simply the best and most accurate available of any competitor data logging system. The GPS makes a unique calculation of position and speed 20 times a second with no interpolation or other “tricks”.
The unique GPS technology has been developed in house by our engineers and tested in the most challenging racing environments – the accuracy is nothing short of a break though at this price point and in this respect there really isn’t any competition.
6g accelerometers are recommended for applications that use large aerodynamic aids.
The drift option uses a built in gyro for measuring vehicle drift (yaw).
GoPro HD Video Synchronisation
Synchronised DL2 data with HD video using the GoPro control option. Included software licence enables HD video by data analysis, and data overlaid video exports from the Analysis software. Control the GoPro using the control cable (compatible with hero, hero 2 and hero 3 white). *GoPro camera not included.
Low Side Drivers and 4 Extra Analogue Channels
Low side output drivers and 4 extra analogue inputs is the option you will require if you want to switch on/off external systems automatically using your DL2. This control can be simple or based on a complicated custom equation between various channel data. This option also enables the 4 additional analogue channels, making a total of 12.
High Accuracy Export
If you intend to use your data in an external application (not just the analysis software) you will need an export licence to output the 20Hz data at full accuracy. The licence enables increased output resolution on GPS latitude, longitude, raw velocity, position, heading, gradient, speed and distance.
2nd Serial Port
A second serial port is ideal for combining multiple input and output modules for complex systems, or driving a low speed telemetry channel on one port and a high speed output for video overlay on the second. Serial port 2 is for receiving data only, serial port 1 can both transmit and receive data.
Built-in ECU Interface
The DL2 can be used to decode serial data directly from an ECU without the need for a separate interface cable. This feature allows a simpler, neater installation, and allows the decoding of more channels than with a separate interface. Enable and disable any channels for a completely bespoke set up, logging as much or as little data as is required. Record raw serial data at 4800, 9600 and 115200 baud rates, which can be useful for fault diagnosis and development.
CAN reception (15 channel license):
With this option the unit can decode any CAN data from either the vehicles main CAN stream or CAN based aftermarket ECU. This data can be mapped to any RT channels for saving or sending to serial port. Up to 105 CAN receive channels per unit, in multiples of 15 (one £100 license gets you 15 channels). Messages loadable using .dbc files. Data rates of up to 1Mbit and 11 or 29 bit addressing.
With this option the unit can transmit any of the internal data channels on the CAN bus at a rate determined by the configuration. A .DBC file is provided with the default channel data and decoding information to make use with third party CAN reception systems much easier. Data for transmission on the CAN bus could be from the internal sensors (GPS, accelerometer, gyro, analogue channels, etc.) or from the serial input from an ECU interface or other unit attached to the serial port. The transmission rate for each channel can be individually configured at rates of up to 100Hz. Transmission can use 29bit or 11bit addressing at a number of different baud rates.
CAN transmit and receive can both be specified on the same port. Each port must run at the same baud rate, if separate rates are required we advise using the second CAN port for this.
RAW CAN reception
Receive and log the vehicle's entire CAN bus data, irrespective of whether it is 11 bit or 29 bit address. Decode it in the Analysis software using DBC files. No need to pre-configure the data logger, just log and decode easily in the software. Perfect for reverse engineering CAN data and using on multiple vehicles. If used with the 1000Hz logging option it can log raw CAN at up to 1000Hz.
Second CAN port
Add a second CAN port to transmit or receive more CAN data. Receive CAN data from another source, ideal for integrating external equipment with a CAN output and synchronising it with the rest of the data.
PWM Output Controller + Advanced Frequency Input
The PWM (Pulse Width Modulation) output controller allows the unit to control an external system with a graduated signal. Meaning it can be "on" anywhere between 1 and 100%. This is ideal for water injection systems etc. This option also enables the advanced frequency inputs, enabling: Pulse counting, pulse high time, pulse low time, pulse position, duty cycle and mark space ratio.
100Hz Live Speed Enhancement
The DL2 is available with optional output of live speed. This option takes the data from the GPS-system and the built-in-accelerometers and combines them using a kalman filter to provide a real time output of speed with is updated at up to 100 Hz and which is resistant to brief GPS outages such as bridges or buildings.
1000Hz Data Logging Enhancement
Measure rapid changes with the 1000Hz sample rate on sensor channels. Essential for accurate suspension analysis, where the high sample rates allow calculation of shock rates as well as measurement of suspension position. If used with the raw CAN option it enables logging of CAN channels at up to 1000Hz.
