Telemetry Laps

ACC Tools provides the Telemetry Laps tool to help you view and manage the telemetry recorded for each lap you drive.

In addition to files it creates and maintains in your Documents folder, ACC makes data available via two programming interfaces (APIs). These interfaces allow applications like ACC Tools to connect to the game and read data.

While it is running ACC Tools is constantly checking to see if ACC is running. When it detects ACC is running ACC Tools connects to APIs and captures the data into a database.

The Status Bar at the bottom of ACC Tools indicates when it has detected ACC is running and when it is connected to the APIs. The indicators change to Green when connected.

Selections

The top section of the Telemetry Laps tool allows you to select a Track/Car combination. Each time you change either the Track or Car the laps for that combination will be loaded and displayed.

This section displays information about the Track and Car you select so you can be sure you have made the correct selection/s.

Laps

The lower section of the Telemetry Laps tool displays all laps that were recorded for the selected Track/Car combination. Laps are sorted by the time the were recorded in descending order, so you most recent laps are shown first.

Invalid laps are highlighted in red.

The table is organised in pages of 30 rows, meaning you have access to all laps via the paging controls at the bottom.

The table shows the following information:

• Track Name
• Car Name
• Lap Time
• Sector 1 Time
• Sector 2 Time
• Sector 3 Time

A Note About Times

At some point you may notice that the times shown in the Telemetry Laps tool do not match those shown in the Broadcast Session tool.

The Broadcast API that we use to capture Broadcast Sessions provides the lap and sector times that the game captures and shows. The Shared Memory API that we use to capture Telemetry does not provide lap or sector times. Instead we have to infer lap and sector times from other data and since we have to poll for this data a frequent intervals (we use 100 milliseconds) matching times is not easy and we chose not to try synching Broadcast and Telemetry lap times.

ACC Tools only captures the telemetry data to support the Lap Analyser so we felt having synchronised times was not important, since the few milliseconds difference would not make much difference when displaying the data points in a graph.

Deleting Laps

The primary function the Telemetry Laps tool provides is deleting unwanted laps. For example you may choose to delete invalid laps (highlighted in red).

Laps can be deleted using the Trash Can icon at the end of each row in the table. Activating this button deletes the lap without prompting for confirmation, so be sure you are deleting the correct row.
