Tokyo Xtreme Racer - Gear Ratio Cheat Sheet Quick Guide

a cheat sheet guide for gear ratios, designed for quick reference!

TL:DR

  • Moving Left = higher speed and less acceleration.
  • Moving Right = lower speed and more acceleration.
  • Set the Default Gear Ratio (it is highest speed + acceleration combo).
  • keep Final as it is, adjust each gear by moving it to the right to gain more acceleration which is needed in races.
  • move 6/5TH gear to the right and lose about 10km/h in speed.
  • move 4/3RD gear to the right and lose about 5km/h in speed
  • move 2/1ST gear to the right and lose about 3km/h in speed.
  • keep doing the above adjustment until you are satisfied with the accelearion.

Understanding Gear Ratios

I. Understanding Gear Ratios

  • Gear Ratio Number (e.g., 2.626, 0.767): Indicates how many times the engine turns for each wheel rotation in that gear.
    • Higher Ratio (e.g., 2.626 in 1st gear):
      • Engine turns more for each wheel rotation.
      • Stronger acceleration.
      • Lower top speed in that gear.
      • Good for starting and accelerating from low speeds.
    • Lower Ratio (e.g., 0.767 in 6th gear):
      • Engine turns less for each wheel rotation.
      • Weaker acceleration.
      • Higher top speed in that gear.
      • Good for cruising at high speeds.

Understanding the "Speed" Number (e.g., "75 km/h" for 1st gear)

This is likely the maximum speed you can reach in that specific gear.

  • It's the speed where the engine is at its limit (redline) or where shifting to the next gear is more efficient for further acceleration.

The "FINAL" Ratio (e.g., "4.385" slider)

  • Master Gear Adjustment: The "FINAL" ratio affects all gears (1st to 6th) equally.
  • Increasing "FINAL" Ratio (towards MAX, higher number):
    • Makes all* gears shorter.
    • Increases acceleration in all gears.
    • Reduces top speed in all gears and overall.
    • Engine revs higher at the same speed.
  • Decreasing "FINAL" Ratio (towards MIN, lower number):
    • Makes all* gears longer.
    • Decreases acceleration in all gears.
    • Increases top speed in all gears and overall.
    • Engine revs lower at the same speed.

Troubleshooting & Tuning

  • Problem: 6th gear takes too long to reach max speed.
    • Solution: Increase "FINAL" Ratio (or, if possible, increase 6th gear ratio directly).
    • Trade-off: Slightly reduces overall top speed (or top speed in 6th gear specifically).
  • Problem: Need more acceleration in all gears.
    • Solution: Increase "FINAL" Ratio.
    • Trade-off: Reduces overall top speed.
  • Problem: Want higher top speed overall.
    • Solution: Decrease "FINAL" Ratio.
    • Trade-off: Reduces acceleration in all gears.
  • Problem: Gears feel too short, hitting rev limiter too quickly.
    • Solution: Decrease "FINAL" Ratio (or, if possible, decrease ratios of lower gears).
    • Trade-off: May reduce acceleration.
  • Problem: Gears feel too long, sluggish acceleration.
    • Solution: Increase "FINAL" Ratio (or, if possible, increase ratios of lower gears).
    • Trade-off: May reduce top speed.

Key Takeaways for Optimal Settings

  • Track Dependent: The "optimal" setting is not universal. It depends heavily on the track layout (corners vs. straights).
  • Experiment! The best way to find the right setting is to test and feel how the car performs.
  • Small Adjustments: Make small changes to the sliders and test. Don't make drastic changes all at once.
  • Balance: Gear tuning is about finding the right balance between acceleration and top speed for your car and the track.
  • No Single "Perfect" Setting: It's about finding what works best for you and the specific conditions.
