i2 Data Analysis

Analysis Components


Graphs are a fundamental part of data analysis and an important tool for seeing changes in data over time or distance. i2's graph component is quick and easy to use. It features:

    • Time Variance Plot
      The Time Variance Plot provides a quick view of where time has been gained or lost between laps, making it easy to focus on areas of difference.
    • Overlapped and Tiled Graph Modes
      Any number of channels can be grouped together on the same scale or configured individually. Channels can be displayed in a simple tiled mode or overlapped for a more advanced view. A simple press of a key toggles between these modes.

    • Dual Cursor Support
      Differential measurements can be made by placing two independently controlled cursors on the one graph. i2 automatically calculates the difference in channel value between the two cursors, as well as the minimum, maximum, average and time or distance differential. Comparisons can also be made simultaneously across multiple overlays.

Multiple Overlay Support

An effective way of comparing multiple sets of data is displaying simultaneously two or more laps from previous outings, sessions or drivers in overlays.

This can be used for highlighting problematic areas or identifying the best performance through a section of track. When evaluating driver consistency it  is easy to see differences in braking points, throttle application and steering input.

Synchronised Video

Multiple video streams (e.g. from in-car cameras) can be linked with logged data for synchronised playback of footage alongside other analysis components. Multiple camera angles can be viewed concurrently and, when overlay data is selected, these views update to show a side by side comparison.

    • Automatic Synchronisation using a MoTeC V2
      Automated CAN Synchronisation of video and data is now available in i2 Standard when using a MoTeC V2. No extra modules or wiring are needed. The software places CAN messages in the video and data files and these are automatically matched up, so users simply download their video and open their logged data and the two are aligned. Currently supported for ADL2, ADL3, SDL3 and ACL.
    • Automatic Synchronisation using a non-MoTeC Camera System‡

      Video from any camera system can be automatically aligned with logged data by recording regular sync points onto the audio track of the video. i2 identifies which video belongs with which log file and automatically aligns the data. This requires the small VSM Video Sync Module connected to an auxiliary output of a MoTeC Dash Logger and to the audio input of the camera. Currently supported for ADL3 and SDL3.
    • Manual Synchronisation‡

      Video footage can also be manually synchronised with logged data, by aligning a specific site in both files. This requires a standard video capture device.


The various i2 reports provide simple to read statistical summaries in both tabular and graphical format.

    • Channel Reports
      Channel reports allow users to view statistical summaries across track sections (or laps) for any number of configured channels. Statistical functions include: minimum, maximum, average and standard deviation along with section start values, end values and their differences.
    • Time Reports
      Section time reports show split times along with gained or lost time for overlays. The report also includes the fastest rolling and eclectic lap times and consistency highlighting.
      Both section time reports and channel reports support export of data into CSV formats.
    • Track Reports
      Track reports present the same statistics as the channel reports but in a graphical format, making it easy to see where the events occurred. The track report also shows one or more channels as a colour gradient which is useful for identifying braking or accelerating areas, or for visualising any other channel. The colour gradients of two laps can also be compared side by side. In addition, i2’s cursor animation feature shows the relative track position at any time during two different laps.


Cursor and Zoom Linking

The graph zoom level and cursor position can be linked to other components such as histograms, scatter plots or other graphs. The displayed data and cursors will shift in accordance with the selection, updating all of the components consistently.

Data Gating

i2 supports advanced data gating, allowing regions of data to be excluded from histograms, scatter plots and other components according to a user specified maths condition.

Graphical Overlay Alignment

i2 provides a simple mechanism to graphically slide the overlay data into precise alignment.


The new i2 maths system provides fast, easy to use facilities.

Fast On-Demand Maths Processing

i2’s maths system uses an on-demand calculation mechanism to reduce data load times. Maths channels are only calculated as needed, so users are never left waiting for unnecessary calculations. This ensures fast access to the data when it counts.

Maths Equation Editor

The equation editor in i2 allows users to enter maths expressions in a simple and easy to read format. With an extensive set of built-in maths functions, new channels can be derived from logged and existing maths channels. Simple import and export facilities enable maths to be easily shared with others.

Predefined Maths Calculations

i2 includes a number of predefined maths calculations, tailored to suit each racing category. For example, circuit racing includes oversteer, pitch and roll calculations while drag racing includes calculations such as clutch slip, wheel lift correction, input shaft speed, and automatic start of run insertion.

Setup Sheets

Setup sheets allow vehicle setup parameters such as spring rates and gear ratios to be recorded for each log file. These values can then be used in maths to create vital analysis channels. The setup sheets are stored in a spreadsheet, giving users a great deal of flexibility in how they use the data.

Data Export

Channel data can be exported for the outing, lap or currently zoomed area. Available export file formats are MoTeC log files, comma separated variables (.CSV) and Matlab files.
When using the i2 API Feature Licence, data can be exported to any desired format.

Automatic Unit Conversion

Units can be automatically converted from, for example, metric to imperial to ensure channels are displayed in the preferred units.


User-defined Track Sections

Any number of sections may be defined for use in reports. This flexibility enables multiple reports to be based on different track sections.


Workbooks‡ and Worksheets

i2’s workbook and worksheet structure is a flexible and intuitive way to systematically organise data into logical screen layouts.

Each worksheet can contain any combination of analysis components like graphs, histograms and gauges, all of which may be individually customised. The software has worksheet templates that can be tailored to individual requirements.

Global Channels Settings

Many channel properties such as colour, display units and minimum and maximum scales can be changed globally to maintain consistency across all data components.

Video Generation‡

The VideoGen feature integrates i2 Pro with Trackvision to generate standalone video files with overlayed gauges. For more information and examples see www.trackvision.net/MoTeC_i2.shtml 

Drag Racing Template

i2’s drag racing support not only includes changes to the menus and terminology but also includes specialised maths functions.

To quickly and precisely align logged data against an actual run, simply enter time slip details and i2 automatically determines the start of the run in the data. Other important details such as lane, weather, split times and terminal speed can also be entered.

i2 Pro is required for these features - see Features
