    For the L120 Enclosed Logger the following upgrades are available:

    120 MB Logging
    The 120 MB Logging upgrade allows for the recording of input data (e.g. from sensors and ECUs) to the L120's internal 120 MB logging memory. It includes use of MoTeC's world class i2 data analysis software.

    Pro Analysis

    Provides access to advanced i2 Pro data analysis software with multiple graph overlays, X-Y plots, advanced maths functions, synchronised video (automatic alignment), and flexible layouts to accommodate virtually any user preference.

    Enables transmission of live data from the vehicle to the pit where it can be viewed in real time using the MoTeC Telemetry Monitor software. Requires radio modems or other means of transmission.

    17 I/O
    Provides additional input/output functionality consisting of: 
    • 6 extra analogue voltage inputs
    • 2 extra analogue temperature inputs
    • 4 extra auxiliary outputs


    MoTeC's fully updatable software is designed to quickly optimise the setup of your vehicle. It is user-friendly with an intuitive menu structure and extensive help screens. To access the newest features you can download the latest version at MoTeC.com.

    •  User-defined conditions to trigger alarms
    •  Calculations including laptimes, lap gain/loss, speed and distance, fuel prediction
    •  Monitor active channels—view all channels live through the Ethernet connection
    •  Sensor zeroing
    •  Details editor including event, venue and vehicle details
    •  Help screens

    i2 Data Analysis Software
    •  Analyzing logged data quickly and efficiently
    •  Viewing data, collected from the L120 internal log memory, numerically or graphically to evaluate the health and performance of the vehicle and to assess driving technique
    •  Monitoring various parameters in order to make improvements to performance and maintain vehicle reliability
    Use of i2 Standard data analysis software is included. In addition, the Pro Analysis upgrade is available which gives access to the i2 Pro version of the software.

    Telemetry Software
    •  Viewing data in real time
    •  Monitoring the engine and chassis from the pit while the vehicle is on track
    The Telemetry upgrade must be enabled to use Telemetry software.


    To complete your installation, MoTeC has a large range of products available, all designed and/or tested to ensure they work well with your data logger.

    Communication Cables
    To configure the L120, a communication cable is required to connect to a PC. An Ethernet cable should be used to connect to the Ethernet port on the PC.

    Lap Timing
    A MoTeC BR2 Beacon Receiver can be connected to the L120 for lap timing as well as calculation features for laptime gain/loss, fuel used per lap and fuel predictions.

    Lambda sensors, position sensors, force and motion sensors, pressure sensors, temperature sensors and speed sensors.

    Radio or GSM modems to send the logged data to a computer in the pit garage to view live in the pits while the vehicle is still on track.

    MoTeC's E888 or E816 Expanders can be connected to the C187 with full functionality.

    GPS units can be used with the L120 for speed, position, track mapping and lap timing, plus date, time and GPS statistics.


    MoTeC’s professional, race-grade electronics are sophisticated and therefore it is highly recommended that installation is performed by a professional installer.  It is NOT advised for the average installer.  An advanced understanding of electrical systems is necessary.  Fischer Motorsports will support all sales and also offers professional grade wiring harnesses and installation services for all applications.  We have 10+ years of professional race experience based upon MoTeC control and specialize in Power train, Chassis, Drivetrain, and Data programming both at our facilities, onsite customer dyno/track support, or even remote support.  Please remember that if you cannot find the time or finances to do the job right the first time, you will ultimately end up looking for time or funds to do it over again.  Select us or find a qualified installer, it will ultimately increase your results and minimize future expenses or downtime related to improper setup or installation.
