Announcing Gear Calcs in ForzaTune Premiere

17 Feb 2010
by Anthony Curtis


After receiving countless requests for gear tuning and researching the best way to make an easy-to-use gear calculator, we present the latest version of ForzaTune Premiere!

Two Apps in One

When you are racing within a class (such as B, A or S) your two biggest advantages are suspension and gear ratio tunes.  ForzaTune now includes tools to help you with both!

Gear Tuning Made Simple

Go ahead and try to find a single gear calculator that is both easy to use and requires minimal keypad input.  Several months of research and development brought together the best parts of every article and spreadsheet on gear tuning.  All you have to do is enter a few things about your car, a target top speed and you are guaranteed to have every gear soak up the powerband.

NOTE: if you have a car with a very low peak torque rpm (one of the inputs for the gearing app) you may get some crazy numbers…in that case just increase the peak torque rpm a few thousand rpm.

Thanks for the Continued Support and Feedback

These tunes are base tunes and will always benefit from your personal tweaks.  Likewise, the premium app continues to grow and evolve with your help–let us know how the app is working for you (email link is in the app).    Version 1.3 also includes updates to the suspension tune screen (to align with the game menus).  Drift and drag tunes are also in the works so check back often or sign up for our email list.

Download your copy now and enjoy the new features!

    Why is iTunes so damn slow?

    Will hopefully get a chance to test out the ratios this weekend.

    Just download the new update and the gear tune is rubbish. I used it set the app to the speed I wanted to reach and it made my car slower than than the defult setting

      If you set the target speed higher than the default speed then yes, the car will accelerate slower. That is the trade-off between gearing for acceleration vs. speed. If you set the target speed a lot lower than the default and you are drag racing then your issue may be traction. That is the trade-off between acceleration and tire grip. Gear tuning is still an art ;)

    Its Good gear tune ratios but its better if they made for all car classes

      They should work for all 6-speed racing transmissions…if the torque rpm is very low or it is a seven speed there may be some tweaking necessary…

      it made my datsun slower

    Thanks guys for adding the gear tune, I really appreciate it! I have one issue though. I think there should be a gear tune for 5 gears as well as 6. Most tracks in Forza don’t need all 6 gears. I used your gear tune and found myself having to shit too much. I Didn’t come close to beating my own ghost with 6 gears. would be a nice feature to add in the next update. Max out 5th gear to the track top speed.

      That fifth sentence made me laugh I didn’t have the heart to correct it…

      Anyway, if you want to max fifth gear out to the track’s top speed just slide the target control until the speed to the right of fifth gear is what you want. I tried to leave the freedom to tune/tweak like this. Tuning out gears may work out well for many folks.

    Something seems way off with the Gearing part, but maybe it’s just me misunderstanding something.

    Went to test it out with a MINI JCW and entered the settings (212 hp, max torque @ 1800RPM, redline @ 6500 [or there-about], ~2600lb curb weight and 215R45-17) and the maximum top speed that the slider would go to was ~531MPH… uhm? And the minimum top speed it would let me set was like ~235.

    Setting the max torque field to 6000 (max power, not max torque) got values much closer to reality.

      I will make an announcement to everyone but let me reply here too: some cars have very low peak torque rpms. This can create some insane numbers if the redline is high. I am recommending that you try to keep the torque rpm no more than 3500 rpm below the redline.

    Let me start off by saying I love your app. I have a huge garage and using your app has saved me a lot of time versus using the flash-based or spreadsheet tuners to tune my 200+ cars. I haven’t had a chance to try out the gear tuner but it seems to make sense. I do have a couple of suggestions, however:

    “Enter Data” page-
    Sliders are somewhat useless, remove to save space?
    Don’t know if it’s possible but on the keypad when you are inputting a number it would be nice to have a “next” button that takes you to the next box.

    “Get Tune” page-
    All the data from this page should be able to fit on a single, non-scrolling page, making it a bit easier to use. This is the biggest one for me and I imagine it would be easy to change.

    Thanks a bunch for such a useful app and keep updating!

    • SwBratcher on April 5, 2010 at 5:28 pm

      I agreed fully with Eric’s suggestions. I would add…

      It could help to see the aero considered for gearing since this is a direct impact on top speed.

      Also, the main gear setting never seems to change. Why is this?

  • Banto on March 13, 2010 at 12:04 pm

    have you planing develop an java(jar) version of this app? is so great but not all have iphone!

  • Steve on April 7, 2010 at 11:35 am


    I am a huge fan of this app and it has saved me a lot of time getting a base tune on a car that I can tweak from there. However I do have a couple of feature requests:

    1) Ability to save a tune to reference later. I have a lot of cars and I share tunes with other people a lot. It would be great to take the values that FT has generated and then mirror any adjustments made in the game from that point and also save it off on the device for reference later (SQLite Database maybe?) I don’t know how some people use the app, however I have found myself talking with someof the people that I race with about car tunes and the ability to pull up a tune that I have in the game would be awesome.

    2) iPad version: The extra screen real-estate in the iPad could really highlight some more advanced functionality (and the request mentioned above) I can provide a mockup of what I am envisioning if it helps. I would hope that the app would be a universal build however :-p

    it would be helpfull if you made a version so that you can switch from like lbs/in to Kgf/mm cause not everyone uses US system. thank you for a great app

  • James on June 29, 2010 at 5:34 pm

    Love your app, I’ve had it since it was only a test release. I have an issue and a question tho. After putting in the cars data and adjusting the Top Speed Target slider the 1st and 2nd gear ratios come out with the same number. Is this for five gear tranny’s or am I doing something wrong? If I skip the 2nd gear result and put in the 3rd gear result for the 2nd gear the gearing is nice and smooth. Not a huge problem but something I’ve wanted to figure out. Thanks for a great app.
