## What is Jetting for Vortex KZ Kart?

Works out the jetting for Vortex kart engines with the DellOrto PHBE 30 and VHSH 30 carburettors, from real temperature, humidity, air pressure and altitude.

ENGINES
RVS with DellOrto PHBE 30, RVS with VHSH 30, RVXX, RVX, RVZ, RKZ, RSZ, RTZ and VTZ, both stock and tuned. For ICC, KZ1 and KZ2 karts.

RESULTS
The recommended setup for the conditions and engine you have set: main jet, emulsion tube, needle and clip position, idle diffuser —on the engines that have one— and idle jet, plus air density, density altitude and relative horsepower. Two ±10 % fine-tuning sliders, high and mid, to suit your engine and how it is built.

CONDITIONS
Weather data from two places: the nearest public station, with its distance and how long ago the reading was taken, 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.

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 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, and mb, hPa, mmHg and inHg.

### 1/5 — Da evitare

*2021-07-14, version 1.1*

7 euro buttati via, fornisce carburazioni completamente sballate (magre)

### 1/5 — App inutile e dati incompleti, risultati errati.

*2017-05-11, version 1.0*

Premesso che a differenza di altre app dello stesso sviluppatore, in questa viene fornito un unico setup anziché quattro come nelle altre. I dati da inserire sono incompleti in quanto non tiene conto né della valvola gas, ne dei giri aria del carburatore. Impostando i dati di carburazione ed i dati di temperatura, Il risultato è assolutamente errato, in quanto propone sempre una carburazione iper grassa. Soldi spesi malissimo

## Version history (last 4 releases)

### 1.3 — 2026-08-20

Version 1.3

SETUP LOGBOOK
• New tab. Save every run with its conditions and the recommended jetting, then note what you actually fitted.
• Rating is separate for low, mid and high: jetting can be lean at the top and rich at the bottom at the same time, and each is fixed with a different part.
• Laps, best lap and maximum RPM too, to compare two runs.
• CSV export, 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.
• Altitude is always stated, including when it could not be obtained.

TRACKS
• 112 tracks with their altitude, taken from the track itself rather than the town. Picking one fills in the altitude and the track type.

SHARING
• Jetting and each run can be shared as an image card.

FIXES
• 0 degrees was being calculated as 25, and 0 % humidity as 50.
• The position screen never worked: the system had stopped reporting the position years ago, and the altitude was stuck at 50 m.
• On the RVS, RVXX and RVX an idle diffuser that does not exist as a part was sometimes recommended. Now it recommends the smallest one that does.
• Fine tuning on one setup leaked into the other three.
• The floats list always ticked the same option, whichever one you picked.
• The app was drawn cropped on modern iPhones.
• Catalan and Russian.

### 1.2 — 2023-11-08

### 1.1 — 2020-10-02

RVS,RVX,RVXX,RVZ,RKZ,RSZ & RTZ engines available
