What's New in Jetting for Dellorto VHSH PRO

2.3

October 10, 2026

Version 2.3 • Apple Watch, widgets and Live Activity: your main jet for right now on your wrist, on the lock screen and in the Dynamic Island all through the track day. • Track mode: the reference jetting large and high contrast, to read it in full sun with your helmet on. And dark mode throughout the app. • Alerts when the weather changes enough to change the main jet or the needle, using the hourly forecast too. • Fuel: 98 E5, E10, E15, ethanol-free, CIK-FIA or race fuel, and the jetting is corrected for it. • Carburettor icing warning, using the criterion of civil aviation. • 144 tracks in 22 countries, and when you check the weather the app detects which one you are at. • Setups and logbook synced through iCloud, and your jetting shared with your mechanic as a link, a file or a QR code. • Location no longer shows an error right after you grant permission, and it works on iPads without GPS. IN EARLIER VERSIONS • 2.2: five Vortex ROK engines with the Dellorto VHSH 30: GP Junior, GP, SV, SVR and Shifter. • 2.1: fuel and oil mix calculator. • 2.0: run logbook, track database with altitudes, jetting as an image card, needle comparison, fine tuning, and the TM KZ-R2 and KZ-R3, Vortex VTZ, Modena KK3 and IAME Screamer 4.

User reviews

Can’t customise?

The app will not allow me to edit carb parts or change measurement units. No access to changing settings. The App just shuts down when these options are selected. Not working as described. Using iOS 18.5

Response from developer

Thank you, and sorry for the trouble. The app was rebuilt for current iOS in August 2026 and the current version is 2.2: logbook, track database, six more engines (Screamer 4 and Vortex ROK GP among them) and a mix calculator. Please update; if editing carb parts or changing units still fails, use Help > Contact and we will look at it straight away.

Bien

Application qui bug un peu mais fonctionne dans l’ensemble vraiment pratique pour régler sa carburation

Response from developer

Merci ! L'application a été refaite pour les iOS actuels en août 2026 (version actuelle 2.2), avec un carnet de piste, une base de circuits et six moteurs de plus, dont le Vortex ROK GP. Si un bug persiste, écrivez-nous depuis Aide > Contact.

Appli qui bugue

L’appli quitte intempestivement quand on veut modifier la carburation ou quand on veut dupliquer une carburation existante. Dommage car l’appli semble intéressante.

Response from developer

Merci pour votre patience. L'application a été entièrement refaite pour les iOS actuels en août 2026 (version actuelle 2.2) : modifier une carburation ou la dupliquer ne devrait plus fermer l'application. Si cela arrive encore, écrivez-nous depuis Aide > Contact.

Keeps Crashing

It’s user friendly but keeps crashing. Only stops if you reset to factory, but after that the graphics seems to go crazy.

It’s also missing the fifth position on the needles adjustment.

If they fix this two points it would be a no brainer 5 stars.

Response from developer

Thank you for the details. The app was rebuilt for current iOS in August 2026 (current version 2.2), with a logbook and six more engines. If it still closes or the needle positions are not all available for your carb, tell us from Help > Contact and we will check it.

VHSH

It would be better if it covered all applications, from Rok GP to KZ , then it would be a tool you could work with. Still fun to see the changes you can try.

Response from developer

Thanks for the suggestion. The app now covers TM, Vortex, Modena, IAME (Screamer 1 to 4, Shifter), Maxter and, since version 2.2, the Vortex ROK GP on the VHSH. Update and pick your engine in the Engine screen.
