IMSA

Live Data Connection

Information

3 type of connections will be available:

Both Al Kamel V2 connections will perform the same and use the exact same protocol.

To connect live to an IMSA event, you need to setup your championship configuration depending of the protocol.

Micro-Sectors

Micro-Sectors are available in IMSA SportsCar Championship using Alkamel v2 feed.

List of loops Per Track

Information

On all tracks, PitIn and PitOut are also available.
You can use these loops to create additional sectors, for example:
InLap: FL;PitIn

Daytona: FL,IM1,T4,T5,T6,T7,IM2,T9,TA,TB,TC,TD

These timing loops can be used to create custom sectors, in the additional options of the championship configuration before connecting. Here is the list of micro-sectors per track for the IMSA SportsCar Championship:

TrackMicro-sectors
DaytonaFL,IM1;IM1,T4;T4,T5;T5,T6;T6,T7;T7,IM2;IM2,T9;T9,TA;TA,TB;TB,TC;TC,TD;TD,FL

You can choose the name you want but the value should always be: Loop1;Loop2

You can only define additional sectors on a computer directly connected to Alkamel V2 North America Protocol (server). Client computers connected via the server mode will receive automatically the same sectors than the server.

tip

Starting from the Daytona tests in November 2025 and for the 2026 season, defining a speed trap is possible (only with the Alkamel V2 protocol): To do that, define it it in the additional options with the following format for the value: Entry Timeline;Exit Timeline;Distance in meters

For example at Daytona, it will be: TC;TD;36.576

Championship configurations examples

Information

Find Below some examples of championship configurations (Daytona):

IMSA Enhanced RMon Timing connection

ProtocolIMSA Enhanced RMon Timing
Host192.168.74.12
Port10030

Additional Option

It happens that some wrong best lap time correction message get send on the IMSA Enhanced RMon Timing protocol. This can lead to laps not being displayed when replaying/activating a session. If this is the case the option can be set to True. By default, the option is at False.

Additional Sectors

In the Additional Options, you can now create your own sectors, using the timing lines names. For example, at Daytona, timelines names are: On Track:T1,T3,T4 In Pits: P5,P1,P2

You can choose the name you want, but the value should be Entry Timeline;Exit Timeline. For example if you want to create a sector from SF Line to Pit Entry, you will need to enter T1;P5 as value:

Championship Regulations

The championship regulations should be set as follow:

Track Maps

The track maps for each events needs to be selected in the IMSA Folder:

tip

The most recent track map is the one without a year attached to it. Previous year tracks, if different would have the year added at the end. For example:

Daytona_3SectorsCurrent Track (used since 2022)

Post Session Replays

Normally, on Tuesday at 12:00PM EST following an event, replays with all the sectors are made available at results.imsa.com/.

The replays are available in the "CSV and Replay" section:

After downloading the files and unzipping the file you should find two files:

  • .txt which is the replay of the session.
  • .csv which is explain below.

Post Session CSVs Data Import

2 types of CSVs can be imported in HH Timing using the Import T&S Data function.

Alkamel "Time cards"

This file can be download directly following a session on results.imsa.com/ inside a specific session. This files only contains the 3 sectors information.

This file can be imported using the Al Kamel North America file format and using the appropriate Timed or Race option.

IMSA CSVs

The IMSA CSVs replays are available in the "CSV and Replay" section normally, on Tuesday at 12:00PM EST following an event. Those files contains all sectors available on track:

This file can be imported using the IMSA Timing file format and using the appropriate Timed or Race option:

IMSA IWSC GTP telemetry

HH Timing can now record and display IMSA telemetry data provided by IMSA GTP telemetry website: https://www.imsa.com/gtp-telemetry/.

Add the Enable Telemetry Reading parameter to the championship config from either IMSA Enhanced RMon Timing protocol (IMSA Timing) or Al Kamel V2 North America protocol to enable the recording.

Enable Telemetry Reading

Recorded from the telemetry, the following columns will be available on the main scoreboard:

  • Energy Rem
  • Energy % consumed Last Lap
  • Energy Refill Time

Main scoreboard columns

Those metrics can be plotted using lap numeric tag graphs.

Lap Numeric Tag Graphs

The Y-Axis can be selected using the Configure Graph option:

Y-Axis Option

Here is an example for the energy remaining:

The Energy Refill Time can also be used directly as an input for the custom ghost using the Incl GTP Refill Time option in the custom ghosts.

Data Fidelity

The intention of IMSA is to provide an immersive experience and insight of the race strategy for fans, TV and radio commentators. Therefore the data is unofficial and may not reflect the reality. The website provides 1 Hz filtered and rounded data.
