Works out the carburation of IAME kart engines — X30 Senior, X30 Junior, X30 Super 175, KA100 and Leopard RL — with a Tillotson or Tryton diaphragm carburettor, from the real temperature, humidity, pressure and altitude, and from the fuel you use.

WHY THIS APP
• Apple Watch app, widgets and Live Activity: your needles for right now on your wrist, on the lock screen and in the Dynamic Island.
• Track mode: your carburation large and high contrast, to read it in full sun with your helmet on.
• It alerts you when the weather changes enough to move the needles, using the hourly forecast too.
• Needles in turns and minutes and in fractions of a turn, the way they are said in the paddock.
• It takes your fuel into account: E10, E15, ethanol-free, CIK-FIA or race fuel.
• 144 tracks in 22 countries with the altitude of the track itself, and it detects which one you are at.
• A run logbook synced through iCloud, and your carburation shared with your mechanic as a link or a QR code, with no accounts.

RESULTS
The four numbers you adjust on a diaphragm carburettor: HIGH-SPEED NEEDLE opening, LOW-SPEED NEEDLE opening, POP-OFF pressure and EXHAUST LENGTH, on the engines where it can be adjusted. Plus air density and density altitude, and two fine adjustments, one per needle.

ENGINE AND CARBURETTOR
Leopard RL, X30 Senior, X30 Junior and X30 Super 175, with Tryton HB27 and Tillotson HW-27A, HB-10A and HL-334AB. The X30 Junior restrictor includes the 22.7 mm one, the current specification since 2021.

IAME KA100: Senior (also Master and KA3 Senior), Junior with the 22 mm SKUSA or Type 3 (KA3) restrictor, and 19 mm KA4, with the Tillotson HW-33A or the HL-398A on engines from before 2016. Stock 5% mix, and the help explains step by step how to set its carburettor.

FUEL
98 E5, E10, E15, ethanol-free, CIK-FIA, leaded race fuel, race E10, oxygenated, or your own with its stoichiometric ratio and density. The app tells you how many minutes the needle opens with yours.

FUEL MIX
Fuel and oil calculator: choose what you want to know — the oil, the fuel or the ratio — and the answer is shown large, in litres, millilitres, gallons and ounces, as a percentage and as 1:n.

CARBURETTOR ICING
From temperature, humidity and the chart civil aviation uses, the app warns you when there is a risk at full throttle, and Conditions tells you whether there is one at idle and on the grid.

TRACK MODE AND TRACK DAY
Your carburation full screen at maximum brightness, how much the density has changed since what you set, and how old the data is. During a track day the needles are 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.

CONDITIONS
From the nearest weather station or typed in by hand; it works the same without coverage.

LOGBOOK
Each run with its conditions and its carburation, what you actually set and how it went, lean, right or rich, low and high. It syncs through iCloud and exports to CSV.

SHARING
As an image card, as a link or as a QR code: your mechanic opens it in their app or, if they don't have it, in the browser.

UNITS
°C and °F, metres and feet, mb, hPa, mmHg and inHg, BAR and PSI, millimetres and inches.

Values are a guide and a starting point.
