Jetting TM Kart for KZ / ICC
TM KZ jetting and logbook
£8.99 · Designed for iPad. Not verified for macOS.
The easiest way to get the most performance out of your TM KZ kart engine. Plus a logbook that keeps a note of what worked.
Works out the jetting for TM kart engines with the Dell'Orto VHSH 30 carburettor, from real temperature, humidity, air pressure and altitude.
ENGINES
K9, K9B, K9C, KZ10, KZ10B, KZ10C, KZ-R1, KZ-R2 (CIK-FIA 2023 homologation) and KZ-R3 (2026 homologation).
RESULTS
Four recommended setups for the conditions and engine you have set. Each one gives the main jet, the emulsion tube, the needle and clip position, the idle diffuser and the idle jet, plus air density, density altitude and relative horsepower. Three ±10 % fine-tuning sliders for high, mid and low to suit your engine and how it is built.
CONDITIONS
Weather data from two places: the nearest public station, with its distance and the time of the reading, or typed in. It works the same with no coverage.
ENGINE
Engine type, floats and their height, oil ratio and track type. Pick the track from the list and the type is derived from the track length, with the altitude filled in for you.
FUEL MIX
A fuel and oil calculator. You choose what you want to know — the oil, the fuel or the ratio — set the other two with your finger, and the answer is shown large, in litres, millilitres, US or UK gallons and fluid ounces. The ratio is shown as a percentage and as 1:n at the same time, and one button sets it in the jetting calculation.
LOGBOOK
Save every run with its conditions and jetting, then note what you actually fitted and how it went: lean, good or rich, separately for low, mid and high. Laps, best lap and maximum RPM too.
Everything stays on your device. The logbook exports to CSV with the difference between what you fitted and what was recommended, run by run.
TRACKS
112 KZ tracks with their altitude, taken from the track itself rather than the town, which are usually different. Search by the track name or by the town.
SHARING
Jetting can be shared as an image card, with the track and the date. The logbook exports to CSV, saves as a backup, and can be imported from another phone.
UNITS
°C and °F, metres and feet, mb, hPa, mmHg and inHg, and litres, millilitres, US and UK gallons and fluid ounces.
Ratings & Reviews
- This app’s overall rating was recently reset.
Version 2.2
FUEL MIX CALCULATOR
• New. You choose what to work out — the oil, the fuel or the ratio — set the other two with your finger, and the answer is shown large.
• In litres, millilitres, US and UK gallons and fluid ounces, with the ratio shown as a percentage and as 1:n at once.
• One button sets it in Engine, and from there it goes into the calculation.
SETUP LOGBOOK
• A new tab. Save every run with its conditions and the recommended jetting, then note what you actually fitted.
• The rating is given separately for low, mid and high: a setup can be lean at the top and rich at the bottom at the same time, and each is corrected with a different part.
• Laps, best lap and maximum RPM too, so you can compare two runs.
• Export to CSV, backup, and import from another phone.
CONDITIONS
• GPS is no longer a separate tab: querying the weather station now sits at the top of Conditions, next to the values you type in. They were two screens for the same job.
TRACKS
• 112 KZ tracks with their altitude, taken from the track itself rather than the town. Picking one fills in the altitude and the track type. Search by the track name or by the town.
SHARING
• Jetting can be shared as an image card, with the track and the date.
ALSO
• A new option to report a problem from the help screen, with your app details already filled in and shown before you send them.
• The help has been rewritten from scratch.
• New launch screen.
• Fixes a display problem on the first screen.
