Tire compliance and proper gearing are crucial for maximizing your car’s performance in Forza Horizon 4. Understanding how adjustments to these settings impact your car’s behavior is the key to successful tuning. Leveraging Forza’s built-in telemetry data provides invaluable insights to fine-tune your ride and dominate the competition.
Unleashing Telemetry Data
Before diving into tuning specifics, enable the telemetry feature in Forza Horizon 4. Navigate to Settings > Controls and select “Telemetry” instead of “Anna.” Once activated, access real-time performance data by pressing and holding down on the D-pad while racing. Use the left and right D-pad buttons to cycle through different telemetry screens. This data will be crucial for identifying areas for improvement.
Tire Pressure: Finding the Sweet Spot
Tire pressure directly impacts the contact patch, which is the area of the tire in contact with the road surface. While often overlooked, maintaining optimal tire pressure is essential for grip and handling. In Forza, aim for an operating tire pressure around 32 psi.
Start with the default 30 psi and observe the telemetry data during a race. As tires heat up, their pressure increases. If pressures exceed 33 psi or fall below 31 psi at operating temperature, adjust accordingly. Prioritize equalizing pressure differences between front and rear tires. For example, if front tires reach 33.5 psi and rear tires are at 32.2 psi, reduce front tire pressure by 1.5 psi.
Gearing: Optimizing for Acceleration and Top Speed
Gearing determines how your car’s engine power translates into acceleration and speed. Shorter gears prioritize acceleration, requiring frequent shifting, while longer gears favor top speed with less shifting. The ideal gearing setup depends on your car’s traction, weight, and power output.
Fine-Tuning First Gear and Final Drive
Begin by tuning the final drive to achieve redline in your highest gear at top speed. For instance, if your car has a 6-speed transmission and a 7,000 RPM redline, ensure the tachometer needle touches 7,000 RPM in 6th gear when reaching maximum velocity. Test this on a long straight, such as a highway.
Next, adjust the first gear to maximize acceleration from a standstill without experiencing bogging down (engine RPM dropping significantly) or excessive wheelspin. If the car struggles to launch, the first gear is too long. Conversely, if the wheels spin excessively, the first gear is too short.
After fine-tuning first gear, adjust the remaining gears sequentially, as changes to one gear impact subsequent gears.
Gear Count Considerations
The optimal number of gears also depends on your car’s engine characteristics. Cars with lower torque output, such as four-cylinder engines or smaller V8s, benefit from more gears (up to 6 in Forza). High-torque engines, like large displacement V8s, often perform better with fewer gears (4 or 5) and longer gear ratios to leverage their torque advantage.
Conclusion
Mastering car tuning in Forza Horizon 4 involves understanding the interplay between tire pressure and gearing. Utilizing telemetry data allows for informed adjustments, leading to optimal performance. Fine-tuning these settings based on your car’s characteristics will unlock its full potential on the track.
