The power of QuickTune is now available for Forza Horizon for the first time!

QuickTune H4 - the successor of the highly acclaimed QuickTune 7 Tuning Calculator for Forza 7 - is now available with full support for Forza Horizon 4!

QuickTune H4 calculates ready-made general purpose tunes for any car in Forza Horizon 4*.

Simply provide following input data:
- manufacturer & car model
- power
- weight & weight distribution
- drivetrain
- suspension (springs and dampers)
- chassis reinforcement
- transmission
- tire compound
- tire width (front and rear)
- installed aero kits
- aero settings (front and rear)

Based on the provided data a tune is calculated for that specific car. ARBs and spring rates are provided with 3 fraction digit precision, set the in-game values to nearest value.

Use the "lb/kg" toggle to switch between imperial and metric unit input.

The "Auto Aero" tuning option can be used to let the app automatically adjust aero levels based on car weight and drivetrain. Automatic aero settings are recommended for all tracks except high-speed tracks.

+ Calculates ready-made balanced and competitive tunes, no tweaking necessary!
+ Supports any car in FH4 with any drivetrain swap
+ Supports non-adjustable stock suspension, race and rally suspension tuning
+ Supports imperial and metric units
+ Automatically keeps track of 100 most recent tuned cars
+ "Auto-Aero" feature for automatic adjustment of aero levels
+ Includes transmission tuning

NOTE: for some cars that have been carried over from Forza 7 available tire and aero upgrades might not be correct. If you encounter any deviation in terms of available tire or aero upgrades drop me a mail at fb@fiftyinch.com and it will be fixed as soon as possible.

Lowkey needed this for a while

I’m horrible at tuning. The descriptions for the tuning in game are too long. This made my car godly!!!

Developer Response ,

Thank you!

Be a lot better if it had different categories for instance drag tunes, drift tunes, etc...
It’s just basically out of the shop tunes that aren’t really good.
