Race Engineer lets you compare two laps directly. You can compare two of your own laps, or compare your lap against a GO Setups Pro Driver or a friend to see exactly what faster drivers do differently.
How lap comparison works
Select any two laps in the Race Engineer interface. The comparison view overlays both laps on the same graph across all available channels: delta, driving line, speed, throttle, brake, steering, and gear. This gives you a complete picture of what is happening at every point on the circuit for both laps.
Start with the delta
The delta trace is your starting point. It shows the cumulative time difference between the two laps as it evolves around the circuit. Look for the sections where the delta swings the most, as these are the areas where the biggest time gains or losses are happening.
Evaluate the reference lap
Once you identify where you are losing time on the delta, switch to the other channels to understand why. Check what the reference lap is doing differently at that point. This could be a tighter or wider driving line through the corner, earlier or more progressive throttle application, a later braking point, or higher minimum speed through the apex. The driving line in particular often reveals positioning differences that are hard to feel in the car but make a significant difference to lap time.
Practical approach
Focus on one or two corners where the delta shows the biggest losses. Study what the reference lap does through those sections across all channels, then work on replicating it in your next session. Tackling corners one at a time is more effective than trying to change everything at once.
