Rotax Jet Tune makes jetting your kart engine to the weather conditions easy.

This one click application automatically retrieves the current local weather conditions from the nearest weather station and quickly informs you of the best jet to use at that time.

Often between races is a hectic busy time getting ready for the next race or worse, fixing mechanical problems. Rotax Jet Tune takes the hassle out of jetting your Kart quickly and easily so that you can focus your attention on other things in preparation for the next heat/race.

Using the data from the familiar Rotax Jetting chart, the apps provides the most accurate jetting setting for your engine.

The app has many great features including the ability to fine tune the calculations to you particular engine using the TRIM function, thus allowing the perfect jet everytime.

Rotax Jet Tune Features include:

- Retrieval of current weather conditions from nearest weather station
- Calculation of the best jet for the conditions based on the Rotax Jetting Chart formulas.
- Granular Single digit jet numbers given - even more accurate than the Rotax Jet Chart.
- Absolute Pressure and Air Density Calculations based on altitude for greater accuracy
- Customisable display values:
- Celsius or Fahrenheit
- Hpa or inHG
- Metres or Feet
- TRIM function allowing fine tuning of the app to your particular engine.
- Own weather data can be used if you have your own weather station

Rotax Jet Tune is the easiest way to Jet your Kart engine.

PLEASE NOTE: This product is for traditional Rotax 125 engines only and is not compatible with the new Rotax EVO engines. Once further information is provided by Rotax of the new EVO engines, an updated version will be forthcoming.

Latest reviews of Rotax Jet Tune app for iPhone and iPad

Working fine - wish it included needle settings
Ive been using this app for a while now over the course of a few track sessions, and it seems to be working correctly - the suggested jet settings all seems reasonable and have worked well for me. My only suggestion would be the addition of needle clip settings - Im never sure when to move the clip from 2 to 3 or 4. Other than that well worth the purchase. Thanks!
Good, simple app!
Seems pretty accurate, may have to adjust trim slightly. Would like to see a needle clip position as well.
