3. Tank Capacity in Litres

  • Input the maximum fuel tank capacity of your car in litres.​

4. Refuel Rate in Litres per Second

  • Enter the refuel rate in litres per second.

    • This is the speed at which your car is refueled during a pit stop, helping you calculate the total time needed for refueling.

5. Fuel Consumption Formation Lap in litres

  • Estimate the amount of fuel needed for the formation lap.

    • Typically, this is less than 50% of the normal fuel consumption during a full-speed lap. Input this value accordingly.

6. Time for Tyre Change Only in Seconds

  • Enter the time in seconds required to change all four tyres during a pit stop.

    • Note that tyre changes and refueling occur sequentially, not simultaneously, so the total pit stop time is cumulative.

7. Pit Stop Delta Full Service in Seconds

  • Input the total time loss during a full service pit stop (maximum refueling and all four tyres changed).

    • This value is crucial for calculating the overall impact of pit stops on your race time.

8. Fuel Delta in Seconds per Litre

  • Enter the time loss per litre of fuel carried.

    • Typically, a car loses about 0.3 seconds per 10 litres of fuel, but this can vary based on the car and track.

    • Uae the FuelDelta calculator on the right hand side.

Personal Tyre Data 2/3

13. +/- Seconds per Lap

  • Adds or subtracts time from each lap time.

    • Add time for average time loss in traffic​.

    • Lower lap times when there will be more grip in the race.

14. Smooth Laps

  • Smooths out variations by incorporating lap times into a mathematical model, ensuring consistent analysis of raw tyre performance.

    • Average stint time will be the same. so you should have already filtered out mistakes manually, or with clear warnings.

15. Tyre Wear Multiplier

  • Input the tyre wear multiplier used during your stint,

    • Doing double or triple stints on a higher tyre wear rate can save a lot of time.

    • Independent from fuel multiplier used during the stint.

16. Estimate Further Laps

  • Enter the number of further laps you want to estimate

    • Uses a mathematical model to predict the performance of further laps based on your input data.

    • The more data you provide, the more accurate the predictions will be.

17. Adjust Fuel Saving Laps

  • Adjusts lap times for fuel-saving laps to reflect what they would have been if driven at full speed.

    • Input the maximum fuel consumption per lap without saving fuel (full push) for accurate adjustments.

18. Fuel Consumption Full Push (in Litres)

  • Enter the maximum fuel consumption per lap without saving fuel.

    • This value will be used as your average fuel consumption for race calculations.

Race Strategy

20. Average Fuel Consumption in Litres

  • Calculated from the Latest Tyre Data:
    This value reflects the fuel consumption rate based on the most recent tyre data you've inputted. It can be either an average consumption rate or the full push consumption, depending on your settings. Adjust this value, if your latest stint was done on a static fuel load.

21. Fuel Consumption Multiplier Race

  • Simulate a Race with a Fuel Consumption Multiplier:
    Adjust this multiplier to account for different fuel consumption rates and see how it affects your overall strategy.

Fuel Delta Calculator

Run Two Full Push Laps

  • Perform a full push lap with the maximum fuel load your car can carry.

  • Perform another full push lap, this time with the minimum fuel load possible.

  • Ensure all other conditions (tyre wear, track temperature, driving style) remain consistent for accuracy.

 

Calculate Fuel Delta

  • The difference in lap times, divided by the difference in fuel loads, will give you the exact time loss per litre of fuel.

Confirm Fuel Delta

  • Confirm the calculated fuel delta to update the Strategy Calculator.

Calculate Fuel Delta

Personal Tyre Data 1/3

The calculator evaluates raw tyre performance based on your input. You can load up to three different tyre compounds and input detailed stint data to optimize your race strategy.

9. Stint Data Input

  • Lap Time and Fuel Load:
    Enter lap times and corresponding fuel loads into the stint data input field. Each row represents a lap.. The data can include pit stops, when double or triple stinting.

  • Load Example:
    Use the "Load Example" button to view a sample of the correct data format, ensuring your input is accurate.

  • Adding Laps:
    Add laps manually using the "Add Lap" button, or copy and paste your statistics sheet from MoTeC into the field.

    Here you wil get the MoTeC workspace.

  • Clear Driving Errors:
    Adjust lap times directly in the input field to correct for any driving errors before importing the data.

10. Including In Lap

  • Filters out the in-lap data when copying and pasting from MoTeC. If you've added laps manually, uncheck this option to include your last lap.

11. Including Out Lap

  • Filters out the out lap. Since the out lap is a push lap on fresh tyres but typically has a slower lap time, checking this option will replace the first lap with the next lap.

12. Clear Warnings

  • Automatically adjusts lap times if significant errors are detected, such as a lap time that is more than 1 second slower than the previous lap. This setting also filters out pit stops during the stint.

19. Import Tyre Data

  • Import the Data:
    Import the stint data from the stint input field, and the full stint will be displayed. Every lap shown here will be used in the strategy calculation.

  • Experiment with Settings:
    Use different settings to see how they affect the results.

  • Select Tyre:
    The strategy calculator provides three slots for tyres: Soft, Medium, and Hard. You can compare three different compounds or test different approaches in how aggressively you push a specific tyre compound.

  • Clear Selected Tyre Data:
    Clears the displayed stint data for the selected tyre, allowing you to reset and input new data if needed.

 

26. Top Stints

  • Shows the Top Stints:
    Displays the stints with the best average lap times, including the corresponding pit stops. This feature helps you identify the most efficient stints based on lap times and pit stop performance, enabling you to optimize your race strategy.

 

27. Best Strategies

  • Shows the Top 10 Strategies:
    Displays the top 10 race strategies. This list helps you quickly identify the most effective strategies for your race.

  • Theoretical Best Strategy:
    The calculator will show the best race strategy in theory for minimizing race time in clean air. For example, underfueling might be slightly faster in theory, but if you end up stuck in traffic, it might not be the best approach.

  • Use as a Baseline:
    Treat this strategy as a baseline. Orient your decisions around it, but be prepared to make adjustments based on the actual race situation. Flexibility is key—adapt your strategy to the dynamics of the race as needed to achieve the best possible outcome.

 

29. Race Plan

  • Review the Full Race Plan:
    Examine the complete race plan, including start fuel and pit stop information. If you are very close to the race length and anticipate an improvement in pace during the race, consider adding an extra lap of fuel to your plan. This precaution helps ensure you have sufficient fuel to adapt to any changes in race conditions.
