You also should enter information about race track is clockwise or anti-clockwise, current weather and race-track conditions (automatic weather detection via the Internet is available). All elements are taking into consideration for calculations - Pressure analysis: you have to inform about the hot and cold pressures of each tyre, matherial of wheels (aluminium or magnesium), target tyre temperature, current weather and race-track conditions - Temperature analysis: you have to set in this screen the information about hot tyre temperatures in the inside, middle and outside of the patch of each tyre, matherial of wheels (aluminium or magnesium), target tyre temperature, current weather and race-track conditions - Temperature: you can set in this screen the information about hot tyre temperatures in the inside, middle and outside of the working surface Then click on the "Analysis" button and application will show you some recommendations related on which adjustments you can do to solve any problem in the chassis setup that you can be suffering.

Fuel calculator, for perfect fuel mixing. Weight and balance to get the perfect go-kart weight distribution. Air density and density altitude for carburetor setup (JETTING). And much more. The app let you use different measure units: ºC y ºF for temperatures, PSI and BAR for pressures, lb and kg for weights, millimeters and inches for length, mb, hPa, mmHg, inHg for atmospheric pressure, meters and foots for altitude, gallons, oz, ml and liters for volume.
