Description
The only jetting app that brings together TM, Vortex, ROK, IAME, Modena and Maxter: 38 engines with a Dellorto VHSH 30. It simulates every setup from the real temperature, humidity, pressure and altitude, and from your fuel, and compares it with the one that worked for you.
WHY THIS APP
• 38 engines from 5 makes, up to the TM KZ-R3, Vortex VTZ, IAME Screamer 4 and Modena KK3.
• A graph compares your setups with the reference one across the whole throttle range.
• Apple Watch app, widgets and Live Activity: your main jet for right now on your wrist, on the lock screen and in the Dynamic Island.
• Track mode: your jetting large and high contrast, to read it in full sun with your helmet on.
• It alerts you when the weather changes enough to change the main jet or the needle.
• It takes your fuel into account: E10, E15, ethanol-free, CIK-FIA or race fuel.
• Carburettor icing warning, using the criterion of civil aviation.
• 144 tracks in 22 countries with their altitude, and it detects which one you are at.
• Synced through iCloud, and your jetting shared with your mechanic as a link or a QR code, with no accounts.
ENGINES
• TM: K9, K9B, K9C, KZ10, KZ10B, KZ10C, KZ-R1, KZ-R2 and KZ-R3.
• Vortex: RVS, RVX, RVXX, RVZ, RKZ, RSZ, RTZ and VTZ.
• Vortex ROK: GP Junior, GP, SV, SVR and Shifter.
• IAME: Screamer, Screamer 2, 3 and 4, Shifter and Super Shifter 175.
• Modena: KK1, KK1R, MKZ, KK2 and KK3.
• Maxter: MXO, MXV, MXE, MXS and MXS2.
SIMULATION
Each setup keeps the engine, the carburettor, the weather and the track. The main screen plots how each one runs, lean at the top and rich at the bottom, against the reference: you see what a jet or needle change does, or what to fit to match the reference in today's weather.
RECOMMENDED SETUP
Pick make and model and the app suggests where to start: main jet, needle and clip, atomizer, diffuser and idle jet. With fine tuning on high, mid and low, remembered for each engine.
FUEL
98 E5, E10, E15, ethanol-free, CIK-FIA, leaded race fuel, race E10, oxygenated, or your own with its stoichiometric ratio. With E10 the main jet goes up by a little over 1 % compared with 98.
CARBURETTOR ICING
From temperature and humidity, the app warns you when there is a risk at full throttle, and Weather tells you whether there is one at idle and on the grid.
TRACK MODE AND TRACK DAY
The reference jetting full screen, how much the density has changed and how old the data is. When you start a track day, for 12 hours the main jet is on the lock screen, in the Dynamic Island and on your Apple Watch, and the app keeps an eye on the weather for you. Dark mode throughout.
WEATHER AND TRACKS
From the nearest weather station or typed in by hand. 144 tracks with the altitude of the track itself; if you are at one, the app detects it and asks you whether that is the one.
LOGBOOK
Each run with what you fitted, what the app recommended, laps, best lap, the weather and your notes. It syncs through iCloud across your devices and exports to CSV.
NEEDLE COMPARISON
Overlays the profiles of two Dellorto needles and shows, at every height, how much passage area one gains or loses against the other.
FUEL MIX CALCULATOR
Oil, fuel or ratio: pick which one you want to know and set the other two. In litres, millilitres, gallons or ounces, as a percentage and as 1:n.
SHARING
As an image card, as a link or as a QR code: your mechanic opens it in their app or, without it, in the browser.
HOW TO USE IT
1. Start from the setup the app recommends and fine-tune it on track.
2. When it works, mark it as the reference with that day's weather, engine and track.
3. Create alternatives and compare them with it. What matters most is full throttle, where you spend most of the lap.
