Le Mans Track Map
The Le Mans track map can be found under WEC/Le Mans in the Track Item. There are a number of options for configuring the main track map display that are specific to Le Mans which are accessible form the main ribbon bar control as shown in the example below:
- Map colored by slow zones rather than normal 3 sectors
- Corner numbers and main sector labels can be hidden
- Slow zone and marshal posts can be shown
Active slow zones will flash yellow when they are active in the track map.
There are 2 different options you have when connecting to the Al Kamel feed in Le Mans. This section describes each option and the implications of using each. We have prepared pre-configured “championships” for each of these options that you can download and import directly into HH Timing to define the connection type, these can be downloaded below:

To import a championship into your project, use the Import button in the Components tab.
If HH Timing Will Not Connect to Feed
If you can not successfully connect to the feed there are two likely causes:
- Your computer can not access the timing server. This will likely be caused be an issue with your team network. If you can not "ping" the IP address of the timing server this means your computer can not access to the the timing data.
- You have exceeded the number of connections allowed by Al Kamel
If you can not successfully connect to the feed and get the message in the lower left corner of the software " Max Number of Connections Reached" this indicates you have exceeded the number of connections allocated to you from Al Kamel.
Normally for Le Mans, Al Kamel give each team one timing connection per car, although you can pay extra for more. If you are getting the Max Number of Connections Reached message and you believe you are not exceeding your connection limit it is best to speak to Al Kamel in person. You can generally find them in the timing and scoring office which is at the pit-in end of the main pit lane building.
Timing Feed Protocols
Al Kamel V2
The Al Kamel V2 protocol is the Al Kamel JSON protocol. The main advantage of the V2 protocol from the user’s perspective is the inclusion of GPS position data in the feed. This allows the following extra features:
- The position of the cars on the Track Map can be defined by their GPS coordinates
- The path (driving lines/position) of cars can be compared
- The speed traces of cars are calculated from the position data and can be plotted
- In addition to the normal 3 sectors, the Porsche Curves, Ford Chicane and T1 and T2 acceleration sectors on the start/finish straight are also included in this feed.
- You must obtain a user name and password from Al Kamel to be able to access this data. This information needs to be entered in the “Additional Options” area of the Championship Configuration in HH Timing.
- There is an option, "GPS" to record rgps (value = rgps), gps (value = gps) or nothing (value = no) from GPS data. rgps is the real value, gps an estimated value. We recommend to set this field to rgps.
- You can choose to record GPS messages in the database if you set "true" as value for Record GPS. As it will only be useful for replays, we recommend keeping the default value, false.
GPS Track Map
For the software to render the cars on the main track map by GPS data rather than the normal interpolation method this must be specified in the main track map ribbon bar control as shown below.
Al Kamel V2 Double Feed
In Le Mans there are a number of additional “timing loops” that are accessible by teams. Al Kamel supply the timing data from these additional timing loops via a separate data feed which means HH Timing connects to two separate data sources and merges them together automatically:
- Al Kamel V2 Feed
- Secondary timing loops
If you select this protocol you need to enter two hosts and two port numbers – one for each feed. You can connect to the Double Feed with a single timing feed connection, there is no need to pay for a second connection.
Note the Al Kamel Double Feed V2 uses the Al Kamel V2 for the primary feed. This means in addition to the normal 3 sectors the Porsche Curves, Ford Chicane and T1 and T2 acceleration sectors on the start/finish straight are also included in addition to the custom sectors that are defined.
By default, HH Timing does not show all the data from the additional loops, the user can define their own custom sectors using the timing loops from both feeds, using the following names:
Create Custom Sectors
With the double feed the user can define custom sectors in the “Additional Options” grid of the Championship Configuration.
The sector name (chosen by the user) is defined in the first column, and the second column defines the start line and the end line for the sector, separated by a ; character (example: S9-1;A11-1 will give you the time between these two lines).
A custom sector can also be defined by the addition of several sub-sectors using the following syntax: StartLine1;EndLine1;StartLine2;EndLine2;StartLine3;EndLine3 ...etc. In that case you can easily sum non-consecutive sectors.
Any pair of loops can be used to define a custom sector, only the start(s) and end(s) loop need to be defined, the loops do not need to be consecutive.
- The name of any of the additional sectors can not be the same as any of the sectors in the main feed which are: S1, S2, S3, PORSCHE, FORD, T1, T2.
- If you make a change to the definition of the custom sectors, for these to be shown in the software the data needs to be re-processed.
- Graphs that are made that include custom sector data may need to be remade if the custom sector definition is changed.
- If CONNECTED LIVE: You will need to disconnect, replay the session you were just connected to, re-connect to the live session (do not clear scoreboard). The data that was sent while you were disconnected will not be recorded by the software. For this reason it is better to stay connected to the live session and only replay to re-process the data once the session finishes if you do not need this additional data during the session.
- If NOT CONNECTED LIVE: Just replay the session with the new sectors definition active and the new sectors will appear.
Speed Traps for Custom Sectors
HH Timing can create speed traps for any of the custom sectors that are defined in the championship configuration. A third argument can be entered after the START and END loops that define the custom sector, which is the distance between the timing loops separated by a semi-colon. An example is shown below in the hypothetical case that custom sector AA4 has 30.7 meters between the two timing loops that define it.
Suggested Race Settings
Options considered critical for the software to operate as intended during the race are summarized below.
Session Settings in Backstage Options
Track Map Options
Select Le Mans track contour
Define the max number of laps for your class of interest. See the Track Item section for a detailed explanation of how these values are applied.
Define the average lap time in seconds of the cars/classes of interest. This is optional and only needs to be used is you prefer to have control over this, otherwise the software will use the average of the best 3 laps in the last 5 for each car as the lap time for forward projections.
Check these are correct:
- Championship Filter
- Tyres and Fuel in parallel
See the Car Following section to make sure everything set to your preferences.
The way HH Timing defines if a lap was under caution/slow zone/SC
- Each of the three safety cars has a number that is locked to it, either 1,2 or 3. This can be thought of in the same way as any other car number, the number is associated with the transponder physically fitted to the car.
- Please review how the Championship Filter is intended to be used if you are unfamiliar with it and make sure it is set correctly to avoid issues with data being blocked or support race data being included in your project.
- There can be cases when a slow zone is removed and the track goes green, however the message is not sent by the time keepers. In this case, there is no way for the software to know that the slow zone has ended. In this case the user can force the track status back to green using the green flag symbol in the lower right corner of the window.
- If you need to restart HH Timing during a session and especially during the race, follow the procedure to get back your old data :
- Right click on the session and use "Recover"
- Wait to get back your old data.
- Connect again without clearing the scoreboard.
