New: jetting for a track you have not reached yet. Name the circuit and the hour you will run, and the calculator works out the jets for there and then.
KartGarage is the all-in-one garage for kart racers. Keep every kart, setup, part and maintenance job organized, dial in carburettor jetting from live weather in seconds, and import a session from your lap timer to see where the time actually went.
YOUR WHOLE GARAGE, ORGANIZED
• Manage multiple karts with engine, chassis, and category details
• See live status and history for each kart at a glance
• Add photos so every kart is easy to identify
• Export a kart as a backup or a readable report, and import it on another device
A SETUP FOR EVERY CONDITION
• Save dry, damp, and wet setup presets
• Switch the active setup in a single tap
• Track how setups perform over time
DIAL IN JETTING IN SECONDS
• Weather-based recommendations for main jet, clip position, and air screw
• Uses temperature, humidity, pressure, and altitude
• Pull conditions where you are, or name any circuit — search it or drop a pin — and the hour you will run
• Send the result to whoever holds the spanner, conditions and all
• Richer and leaner alternatives when you want a safety margin
• An hourly forecast showing the exact hour your jet needs to change
• A spark plug heat range for the same conditions, from your engine's own ladder
SEE WHERE THE LAP TIME WENT
• Import a session from AiM XRK, Unipro UNI/TSV, RaceBox CSV or GPX
• Every lap timed from GPS, with best lap, consistency, top speed, max RPM and head temp
• Place the start line and the splits on the track map, then read sector times off it
• Save a track once and everything you log there stays comparable
• Compare two laps and see exactly which stretch cost you the time
• Draw speed, RPM, head temp, cornering g, braking g or altitude along the lap
• Every session keeps the setup that was on the kart and the weather it ran in
QUICK MATHS FOR THE PADDOCK
• Sprockets and speed: ratio, rollout, top speed and the curve, per engine
• Chain length: links for a sprocket pair at your real centre distance
• Sprocket equivalence: match a ratio using only the sprockets you own
• Fuel mix: oil for a tank at your ratio
• Measure your rear tyre once and every speed on screen follows it
CATCH WEAR BEFORE IT FAILS
• Track part life by engine hours
• Manage a parts warehouse and know what's fresh
• Log tyre sets and keep an eye on their condition
ARRIVE RACE-READY
• Time- and usage-based maintenance reminders
• Plan race day events with a packing checklist built from your warehouse
• See what's due across every kart before a race weekend
• Build shopping lists per kart so nothing is forgotten
• Search for a part online from the list, and keep a link to the listing you chose
• Share the list, or only the lines you pick, as plain text
KEEP YOUR GEAR LEGAL
• Track helmets, suits, gloves, boots, and rib protectors
• Store the homologation standard, number, and validity dates
• Get warned before anything expires
BUILT FOR THE PADDOCK
• A guide you can open and search any time, with step-by-step help for the jobs that cross several screens
• Fast, clean light and dark themes, both readable in daylight
• Works fully offline, so your data lives on your device
• Available in eight languages

JETTING FOR A TRACK YOU HAVE NOT REACHED YET
The calculator only ever asked what the weather is here, now. Name the circuit instead — search it, or drop a pin on the map — and the hour you will be on track, and it works the jetting out for there and then. Useful the night before, when the van is half packed and the meeting is three hours away.
ONE ANSWER INSTEAD OF TWO CARDS
The main jet and the spark plug come out of the same air, so they are one block now rather than two cards a screen apart, with the conditions they assume printed beside them and the confidence figure above. Apply to Setup says what it is about to overwrite before you tap it.
THE SAFETY NOTICE STAYS
The jetting notice could be dismissed permanently, and nothing anywhere brought it back. It is part of the screen now, on every tab, and it opens the full text along with the two warnings that used to be buried — lean running, and what too hot a plug does to a piston. There is also a copy in Settings under Legal.
SEND THE RESULT
Share on the jetting result sends the fitment to whoever is holding the spanner: engine, carb, jet, plug, needle and clip, with the conditions it was worked out for. Plain text, so it lands readable in any chat, and the safety line travels with it.
HOME SHORTCUTS YOU ARRANGE
The shortcuts are squares now, each showing the one figure worth a glance — days to the next race, parts overdue, lines still to buy. Telemetry leads. Drag them into the order you want from the Customise tile.
TELEMETRY AND SETUP
Sector times sit in columns under S1, S2 and S3, and the fastest sector of the session is purple the way a timing screen has always said it. On the gearing graph, the same ratio on the next front sprocket up or down is spelled out, with a way straight into the equivalence tool.
SHOPPING
Share sends what you are looking at to whoever is ordering; tap Select on a group heading to send only part of it. A line can hold a link to the listing you chose. The In warehouse group starts folded, and the free limit counts only what you still have to buy.
NOW IN EIGHT LANGUAGES
KartGarage is translated into Italian, French, Spanish, Portuguese, German and Dutch, alongside English and Polish. It follows your phone, or you can pick a language of your own in Settings.
FIXES
• Rotax DD2 Pre-EVO: any carb build other than the default was given the leanest main jet in the range, and a clip three positions lean with it. Corrected. If you run a DD2 Pre-EVO, check the numbers against what you were given before.
• A named place now brings its altitude with it, instead of leaving your own.
• The keyboard no longer covers the field you are typing in on the place, engine, carburettor and part pickers.
• Photos taken in landscape are no longer squashed into a square.
• Backing out of a screen opened from Home animates instead of jumping.
• Tapping a card's ⋮ on Lists no longer pages the hub to the next tab.
• Polish: the preset summary and the overdue count are translated rather than printed as stored English.
