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 "hp/kw" and "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. 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

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.
