Jetting for KTM 2T Dirt Bikes

Version 2.2 FUEL • New: choose your fuel — pump petrol, E10, E15, ethanol-free, race or motocross — and the jetting is corrected with its stoichiometric ratio and density. CARBURETTOR ICING • New: an icing warning from the temperature and humidity. On enduro bikes (EXC, XC-W and MXC) it also warns at higher temperatures. TRACK MODE AND TRACK DAY • Your jetting full screen, large and high contrast, to read it in full sun with your helmet on. • A 12-hour track day: the main jet on the lock screen, in the Dynamic Island and on the Apple Watch. • The app follows the phone's dark mode. WIDGETS AND APPLE WATCH • Home and lock screen widgets and an Apple Watch app with complications. ALERTS • If the weather changes enough to change the main jet, it tells you. ICLOUD AND SHARING • The logbook and settings sync through iCloud between your devices. • Share your jetting with your mechanic as a link, a file or a QR code. AND ALSO • Location now works on iPads without GPS and indoors. • Report a problem from Results and from Help. • The distance to the station no longer shows as "0.0 km", and "More apps" looks better. IN PREVIOUS VERSIONS • 2.1: a fuel and oil mix calculator, and a new icon. • 2.0: a ride logbook, the weather station inside Conditions, a new launch screen, rewritten help and seven new model and year combinations.

It works out the jetting of your two-stroke KTM motocross or enduro bike (SX, SXS, EXC, XC and MXC models, 2005 to 2027) from the temperature, altitude, humidity, pressure, oil ratio and the fuel you use. Every recommendation starts from the reference setup for that model and year and is corrected by the air density of your conditions: a starting point worked out for the day in front of you, not a rule of thumb from a forum. WHY THIS APP • Two-stroke KTMs up to 2027, every year and model in the list below. • Track mode: your jetting large and high contrast, to read it in full sun with your helmet on. • Widgets, lock screen, Dynamic Island and an Apple Watch app: your main jet for right now, always at hand. • It alerts you when the weather changes enough to change the main jet, using the hourly forecast too. • It takes your fuel into account: pump petrol, E10, E15, ethanol-free or race fuel. • Carburettor icing warning, with a stricter criterion for enduro. • A ride logbook synced through iCloud. • Share your jetting with your mechanic as a link or a QR code, with no accounts. • No ads, no tracking, no account. WHAT IT INCLUDES • Main jet, needle and clip, pilot jet and air screw for your conditions, with fine tuning. • Weather from the nearest station in one tap, or typed in by hand with no coverage; altitude from the GPS. • Air density and density altitude, always on screen. • Fuel: 95/98 E5, E10, E15, ethanol-free, leaded race fuel, race E10, oxygenated, motocross, or your own with its stoichiometric ratio and density. With E10 the main jet goes up by about 1 %. • Carburettor icing: using the chart civil aviation uses, it warns on motocross bikes in cold, humid air and, on enduro bikes (EXC, XC-W and MXC), at higher temperatures too. • A 12-hour track day: the main jet on the lock screen, the Dynamic Island and the Apple Watch, with alerts when conditions change. • Ride logbook: what the app recommended, what you fitted and how it went at low, mid and high. Synced through iCloud and exported to CSV. • Fuel and oil mix calculator, in litres, millilitres, gallons and ounces, as a percentage and as 1:n. • Share with your mechanic: link, file or QR code. • Dark mode. UNITS ºC and ºF, metres and feet, mb, hPa, mmHg and inHg, and kg/m³, lb/ft³ and lb/gal (US) for air density.
