What's New in Jetting for Rotax Max EVO Kart

2.4

August 19, 2026

The track logbook, auto calibration and six more languages. • Track logbook: save every session with the circuit, the conditions, the jet you actually fitted, how it felt, the laps and the best time. Exports to CSV. • Auto calibration: with several sessions saved, the app spots whether your engine systematically asks for more or less than the recommendation, and offers to set it as your default fine tuning. • Share the setup as an image, to send it to the team group. • The recommended jet now shows both neighbours, in green when the choice is clear and in amber when the real value sits halfway between two. • Fine tuning works in steps of 0.5 and tells you what each step achieves, instead of moving an abstract number. • Oil type: you can record whether you run XPS Castor, synthetic or something else. It is stored with your setup and in every logbook session. • Micro MAX and Mini MAX are now identified by specification rather than year of manufacture: the MY20 kit can be retrofitted, so a 2018 engine that has been updated is MY20. • Weather and GPS were the same task split across two screens: they are now a single Conditions screen, showing when the reading was taken and warning you if it is more than 30 minutes old. • The interface has been rebuilt: dark mode, system text size, VoiceOver, rotation and a proper iPad layout. • Six new languages: Catalan, Danish, Dutch, Norwegian, Swedish and Traditional Chinese. The app is now available in thirteen languages. • The help on every screen has been rewritten and brought up to date. The calculation model is unchanged: for the same conditions and the same setup, the recommended values are exactly those of the previous version. Oil type does not change it either, because what drives the calculation is the percentage, not the base of the lubricant.

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 😪
