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

Great app! Drift Tuning?

I love this app, makes a dialed track car out of anything u setup on your own. The four-star rating felt suitable because although I do really enjoy using it, there are definite improvements that could be made. For instance, explaining why the generic tunes (brake pressure) are used in almost all cars would be nice for beginners, and having a more detailed and visual interface would be a great improvement as well.

My biggest wish: We need an app that can do DRIFT SETUPS. I know this is a very new way of setting up cars but I think us nerds could come up with an easy algorithm or program to read the data for us just like this racing setup does now. Anyways those are my thoughts, just a friendly Forza nerd trying to improve the gaming experience for racing community!

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!!!

No option for drag tuning

I bought this app so I could make my drag times better, but it seems that it does not help it just makes them slower.

Developer Response ,

Drift and drag tunes are not supported right now by QuickTune H4 but may come with a future update.
