What's New in Jetting for Rotax Max EVO Kart

2.6

October 4, 2026

Version 2.6 • Apple Watch, widgets and Live Activity: your main jet for right now on your wrist, on the lock screen and in the Dynamic Island throughout your track day. • Track mode: your jetting large and high contrast, to read it in full sun with your helmet on. • Alerts when the weather changes enough to change the main jet or the needle: "Air density has risen by 1.6 % since your last calculation. The main jet stays at 125; the needle goes to clip 4". • Fuel: 98 E5, E10, ethanol-free or race fuel, and the jetting is corrected for it. • Carburettor icing warning, using the criterion of civil aviation. • 144 tracks, and when you fetch the weather the app detects which one you are at. • Logbook synced through iCloud, and your jetting shared with your mechanic as a link or a QR code. • Location also works on iPad without GPS and indoors, and reporting a problem is one tap away from Results. The calculation coefficients do not change: with 98 E5, the usual fuel, the result is the same as before. IN EARLIER VERSIONS • 2.5: fuel and oil mix calculator, and a refreshed icon. • 2.4: track logbook with self-calibration; Micro and Mini by spec (MY20) instead of by year; the two neighbouring jets; sharing as an image; Conditions on a single screen; new interface with dark mode and six more languages. • 2.3: the app renewed for iOS 26, with engine years up to the current one and 0 °C no longer read as 25.

Response from developer

Merci pour votre retour. La version 2.5 (août 2026) est une mise à jour complète : catégories Micro, Mini, Junior, Senior, DD2 et Masters, gicleur principal, position d'aiguille et bougie, calculateur de mélange et carnet de piste. Si un réglage vous semble faux, envoyez-nous la catégorie, la météo et le gicleur monté depuis le menu Aide : nous vérifions chaque cas.

Très peu d’info

Ne tiens pas compte du style de carburant, ne donne pas d’info sur la hauteur de l’aiguille, pas d’info sur la vis d’air. Malgré un bulletin de Rotax sur les 2024 de fonctionnement avec gicleur plus gros… aucun changement si on change l’année. Des dollars gaspillés pour une application vraiment pas terrible

Great app for racers

This app has boosted the performance of my son’s engine. More rpm at top-end and better mid-range.

Main Jet Size

Is the calculated main jet size the number stamped on the jet or the diameter measured with a pin gauge?

Altitude MILES out

App was ok now has a glitch on the altitude, it’s approx 1000 Mtrs out so the gps data is useless, reloading app, trying on different device gives same results, emails sent no reply 😪
