Laptiming
Description
At 2D modules, laptimes can be created in many ways, e.g. using GPS coordinates or TransponderX2 messages as lap trigger signals to display the lap time live at the track on 2D dashboards or in 2D Analyzer.

Respective manuals can be found at our website: www.2D-Datarecording.com/manuals/
Beside these two live functionalities it is also possible to create and analyse the laptimes in post-processing in Analyzer.
Even the GAP time function can be readjusted in the Analyzer in post-processing (see here).

Attention
If no laptriggers are created by clicking on <OK> please check the Timeout settings MinLapLength and MinLapTime in Race.ini in application data directory (WinARace shortcut <CTRL> + <ALT> + <D>)
Via Analyzer tab Functions (or shortcut <ALT> + <L>) the laptime overview can be opened
Section Time
When laptriggers are created in Analyzer via tab Functions the Section table can be opened.
Open Section time table via Analyzer tab Functions or pressing <ALT>+<S>
Attention
If no section triggers are already existing, the software ask to insert sections. The software always adds three default sections with same size by using lapmeters!
Section time table (best sections are highlighted in green)
Important
Via Delta button in lower left corner of the sectimes table, the dispayling can be switched to “delta-to-fastest-section”-mode.
Ideal time
The in section time table shown Ideal time is created by all best sections of the current measurement.
Create via Lapmeter
Attention
If no section triggers are already existing, the software ask to insert sections. The software always adds three default sections with same size by using lapmeters!
Section triggers can be created in multiple ways.
In this section it is described how to create section triggers by lapmeters.
Edit default entries
When section triggers are created by lapmeters, by right-clicking on sectimes table, the sections can be edited.

Attention
If more section triggers should be added to list press Close and repeat step 2 & 3 for every desired section trigger again.
If all desired section triggers are added to list press on Create triggers in area Complete section list (user) to create GPS sections

Post-processing Time/Distance channels
Important
A measurement of the BMW M1000RR in Hockenheim was used as an example
Preparation
Open REFERENCE measurement in Analyzer
Navigate to reference lap (e.g. fastest lap) and adjust zoom and view that only reference lap is shown in moving window
Fastest lap in reference measurement
Important
The shown dropdown menu can be used to navigate to fastest lap!
Navigate to fastest lap via dropdown menu
Load comparison lap of same measurement (e.g. via dropdown menu) or lap from other measurement
Load lap icons
Switch x-axis unit from time [V(t)] to distance [V(s)]
Switch from time to distance distance plot
Important
When comparing laps, it is better to use the distance as x-axis, as the lapmeters do not vary as much even with different lap times.
Align measurements that both start triggers are overlapping
Important
By using <page-up> and <page-down> keys it can be jumped between the same positions of different laps in measurment!
When reference and comparison lap are aligned, link the two measurements by pressing the marked button or key <v>
Link shown measurements
Activating channels
Open the channel list by pressing the marked button or using shortcut <ALT> + <u>
Open channel list
Select filter for virtual channels
Select virtual channels in channel list
Important
For all channels different colors and scalings can be freely chosen!

Examples
Time diff
Channel Time diff in measurement overlay
As a result of braking 25 m later in comparison lap, the rider effectively wins 0.51 sec time in compared to reference lap (Time diff from -0.27 +0.24) at acceleration, but because of the higher velocity at the straight, the rider misses the brake point, and loses time again. The gap of about 0.16 seconds hardly changes during Parabolika.
At the end of the comparison lap the rider has lost in total 0.66 sec (Time diff -0.66 sec) seconds compared to reference lap.
Win change
Channels Time diff & Win change in measurement overlay
The time gain because of later braking in comparison lap described above can be better read from the channel Win change, because if this is in the positive value, there is a time gain because of better acceleration phase. Also missing the brake point at the end of the straight becomes obvious due to the rapid change to a negative value of Win change.
TDiff Window
Channel TDiff window in measurement overlay
In order to anlyse only desired sections of a lap the TDiff window channel is used and the position of the moving window is changed, e.g. that Parabolika is at the beginning of moving window, as this channel always calculates the time difference from the current position of the moving window.
This very quickly reveals significant positions where the driver loses or wins time in different sections of the comparison lap.
Analyzer Settings
Via Analyzer options, which can be opened by pressing <F9>, it can be set, that when a second measurement is loaded, that channels Time diff and TDiff window are activated automatically and distance plot is activated.
