Can’t customise?
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

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
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 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
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.
