KartGarage: Jetting & Setup

Built for racers who run their own karts: jetting from the day's air, gearing worked out before you touch a sprocket, and your data logger's laps laid out on the track map. No account needed.

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 at any circuit and hour
• Send the result to your mechanic, conditions and all
• Richer and leaner alternatives for a safety margin
• An hourly forecast showing when 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 — or straight off a MyChron 5 over its Wi-Fi
• Every lap timed from GPS, with best lap, consistency, top speed, max RPM and head temp
• Place the start line and splits on the map and read sector times
• Save a track once and everything you log there stays comparable
• See which corners each lap lost time in, why, and what to try next time
• Compare two laps corner by corner, at the same places on the track
• 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

A SETUP FOR EVERY CONDITION
• Record the whole kart: carburetor, gearing, tire pressures hot and cold, caster, camber, toe and ride height
• Save dry, damp and wet presets and switch between them in a tap
• Put two presets side by side and see only what differs
• Type a pressure straight off your gauge, in metric or imperial

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

CATCH WEAR BEFORE IT FAILS
• Track part life by engine hours
• Manage a parts warehouse and know what's fresh
• Log tyre sets and their condition

ARRIVE RACE-READY
• Maintenance reminders on time or engine hours, across every kart
• Your mechanic's checklist by trigger, ticked kart by kart
• Plan race day events with a packing checklist built from your warehouse
• Build shopping lists per kart
• Search for a part online and keep a link to the listing you chose

YOUR WHOLE GARAGE, ORGANIZED
• Manage multiple karts with engine, chassis, and category details
• Back up the whole garage in one file and restore it on your next phone
• Export a kart as a file or a readable report

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 searchable guide, with step-by-step help for jobs that span several screens
• Works fully offline, so your data lives on your device
• Available in nine languages
