From time to time, you might see a car that doesn’t allow you to upgrade or add more power, which means Forza Motorsport and Horizon will not show a power/torque graph. If you use the gearing calculator in ForzaTune this can leave you wondering where to find the RPM for peak torque.
Not to worry! You can always go for a test drive.
A ForzaTune fan, Theodore, wrote this great summary. Here’s how he gets solid data for gearing when the game’s graph is missing or hard to read…
- After upgrades and before applying ForzaTune, take a test drive at the 1-mile Test Track drag strip in Motorsport or highway in Horizon.
- Launch in a high gear (3rd or 4th)
- Show telemetry and use the first screen to show power, torque and RPM.
- Knowing the max torque from the Forza specs, watch for the first drop in torque during acceleration and make note of the RPM. To be sure, repeat several times.
- For redline, accelerate until the valves float and chatter, deducting 100-200 RPM from the telemetry indications.
- This approach takes a little longer, but removes the guesswork when graphs are missing or too flat to read.
You can also make use of the replay feature in Forza Motorsport as another user, Chris, commented:
Run a short race where you are accelerating, then quit and go to View Replay. Pull up the telemetry and use the brakes and acceleration buttons to slow down or increase the speed of the replay. Do this while telemetry is showing and what results is an RPM for accurate torque measurement without having to immediately divert your eyes from one part of the screen to the other.
