ForzaShiftTone

Windows GUI application to provide a shift tone in Forza Motorsport and Forza Horizon 4/5.

TL;DR

• Per gear: Drive around on flat tarmac until you hear a double beep
  • Maintain fixed speed if it has trouble locking the gear ratio
• On a flat straight: Hold full throttle starting from low rpm until you hear a triple beep
  • Use a gear with low/no wheelspin but able to hit revlimit before the end of the straight
  • Try again if you hit the rev limiter for several consecutive seconds with no triple beep
• Be aware that false positives exist: not every beep is an upshift.

Enable Data Out in Forza Motorsport / Forza Horizon 4/5

To configure Data Out (remote telemetry) in supported Forza games on Steam for this application:

• Head to Settings -> Gameplay & HUD -> scroll down to the bottom (HUD and Gameplay in Forza Horizon 5)
• Set Data Out to On, enter 127.0.0.1 as Data out IP address and Data out IP port 12350. You may have to restart the game.
• The Data Out Packet Format should be set to 'Car Dash' for Forza Motorsport
• The Microsoft Store version may require a 3rd party Loopback Utility
• It is unknown whether the Data Out functions on the consoles at all
  • If it works, enter the IP address of your laptop instead of 127.0.0.1

Known issues

• Application will on rare occasions crash: related to the UI library and cannot be fixed
• Due to noise in the power curve it is not always possible to derive a correct peak power value in terms of rpm. It can be off by 100 rpm.
• Gear ratios may not reasonably match in-game values for AWD: Front/rear tires may have different sizes
• Probably more, will be added later.
