Setup Optimiser is a feature inside GO Fast that helps you improve your car setup through a guided feedback process. Instead of guessing which setup changes to make, you describe the handling issues you are experiencing and Setup Optimiser suggests specific adjustments based on your input.
How it works
Setup Optimiser uses a four step process where you provide feedback about how the car feels on track. You do not need to interpret telemetry data yourself. The app guides you through each step and generates setup changes based on your answers.
- Choose the problem. Select the handling issue you are experiencing, such as understeer, oversteer, or instability over kerbs.
- Pick where it happens. Identify the corner phase where the issue occurs: entry, mid corner, or exit.
- Set the speed range. Specify whether the issue happens at low, medium, or high speed corners.
- Rate the severity. Use a scale from 1 to 5 to indicate how serious the problem is.
Once you complete these steps, Setup Optimiser suggests specific setup parameter changes. In ACC, the adjustments stay within recommended limits set by professional sim drivers, so the car remains balanced and drivable.
Applying changes
How changes are applied depends on the sim you are using. In ACC and LMU, Setup Optimiser can apply the suggested changes to your setup automatically. In iRacing, setup files are encrypted by the game, so you will need to apply the changes manually in the garage.
Getting started
To use Setup Optimiser, drive a few laps and focus on how the car feels. Then open Setup Optimiser in GO Fast, and select the setup you want to optimise. You can choose one of your own setups or a setup from the GO Setups library. If you are in an active session, the car and track are detected automatically.
Testing and refining
After applying the suggested changes, go back on track and drive at least three laps to test the result. Then return to Setup Optimiser and choose one of the following options:
- Problem solved. The issue is gone and you can move on or address a different problem.
- Same problem. The issue persists. You can adjust the severity rating and get updated suggestions.
- Different problem. The original issue is resolved but a new one has appeared. Start a new feedback flow for the new issue.
- Wrong direction. The change made things worse. Undo the adjustment and restart with different input.
This feedback loop lets you refine the setup step by step until the car handles the way you want.
