## What is Tune It Yourself?

*Try it for free, full version requires a paid subscription*. Tune It Yourself makes use of the in game telemetry feed and advanced algorithms to tune each race car to the driver and circuit conditions. 

Using improved tuning formulas and a brand-new tuning technique, Tune It Yourself connects with Forza Motorsport 2023, Forza Motorsport 7, Forza Horizon 4 or Forza Horizon 5 and collects live data from your car as you race. This allows Tune It Yourself to automatically adjust your base tunes using the data gathered from your time on track to tailor the suspension and gearing setups for both the car and the track it is on.

The trial version of this app allows the user to tune the KTM X-Box GT4 on any track in Forza Motorsport 2023, the Radical SR8 on any track in Forza Motorsport 7, the 1993 Skyline GT-R VSPEC in Forza Horizon 4 or the 1992 Ford Escort RS Cosworth in Forza Horizon 5. To tune other cars, a Tune It Yourself subscription is required which can be purchased from within the app.

### 5/5 — Very handy

*2025-12-20, version 1.6.8*

This app works like a charm.  Want a good tune this app is the one you need

### 5/5 — tuning made simple

*2024-09-19, version 1.6.8*

This app is so easy to use and is just what I have been looking for. I love to drive but was never a fan of the tuning part as I always overthought everything and would only make it worse! this app just tells me what to change and it will make you faster from my experience.....Thanks for making this app!

### 2/5 — Time it yourself

*2024-07-09, version 1.6.8*

Not to happy trying to set up and when it says take car for 60 mph test run it does not connect I double check the out put numbers and they match

### 5/5 — drag racing idea

*2024-05-01, version 1.6.8*

would love to see a drag race type update expecially for gearing its a very solid app love using it when i have time to tune would live to see gearing for drag racing and mayby a setup

### 3/5 — Improved after recent update

*2024-03-11, version 1.6.6*

Overall greatly improved tuning flow after the most recent update. Could also improve:

Spring stiffness tuning (I may be wrong on this one) would be good to understand whether curbs impact the stiffness setting and if yes, eliminate them from telemetry data in test laps or adjust instructions for test laps to avoid spring stiffness becoming too high if it’s affected by the curbs. Eg: if the springs bottom out on curbs doesn’t mean they’ll do so during the normal conditions
Same goes for anti-roll bars - not sure if these are being affected by the curbs
Some sort of prompt on Differential balance adjustment to understand which will be affected: entry, mid or exit and a consideration for AWD cars

Would be good to have:

An option to adjust the final drive using a slider (in the final tune) and get updated ratios. 
Clear instructions before the test laps if the crashes or curbs may affect the final tune in tests which may be impacted by this

Overall, very positive changes with the recent update. Would be great to see more improvements to the tuning flow to make it more intuitive and more options to play around with the final tune adjustments

Original review (pre-2024):

Very unintuitive interface. Instructions lack clarity. Odd spring tension rates. Algorithm and formulas need updating. Was able to achieve much better results with a different app and even using calculations in an Excel spreadsheet, especially for gearing tuning. Not sure what’s the point of the app receiving telemetry data if it fails to use this data correctly. Waste of money but most importantly - waste of time.

### 5/5 — Sooo Fast

*2024-02-17*

Takes about an hour to go through tuning process and will make you way faster

### 4/5 — Pretty dang good!

*2024-02-15, version 1.6.5*

Love the app for RWD cars.  Could you please add FWD as an option?

### 5/5 — Love it!

*2024-02-04, version 1.6.5*

I’ve never been any good at tuning cars in Forza, until I found this app.

### 5/5 — Excellent

*2024-01-26, version 1.6.5*

Great app for tuning in the new Forza Motorsport, would recommend if your not to hot on tuning!

### 5/5 — Easy fun

*2023-12-13, version 1.6.3*

Great easy fun
