### 5/5 — Thanks

*2019-02-25, version 1.0*

Looks very usefull. Also I use version for EVO engines from this developer!

### 5/5 — Great app

*2019-02-19, version 1.0*

Took some fiddling around as jetting needed to be skewed quite a bit to match my setup, otherwise jetting now is very very consistent, a lot less guessing and fooling around with the engine.

### 5/5 — Big help

*2019-02-18, version 1.0*

Simple and easy to use. Good for beginners.

### 1/5 — App no good

*2020-11-22, version 2.0*

Paid $13 for an app to tell me that my kart that is leaning out too much with a 160 jet needs a 120 jet. That makes complete sense. Also the app doesn’t allow for changing the idle jet sizes. I run 60/30 idle jets and it only allows 60/60 or 30/30. If the app developers could refund my money that would be great. Thank you.

### 3/5 — Jetting Rotax max

*2021-02-17, version 2.1*

Температура ставится только до -10 , положение иглы вообще неменяется во fristaile

### 4/5 — Ошибка

*2023-08-06, version 2.2*

При выборе на вкладке Двигатель параметра — «3,6 g (idle jet = 30, idle emulsifier = B60) – best opinion with needle K98» на вкладке Результаты параметры остаются: idle jet — 60, idle emulsifier = B60.

Исправьте пожалуйста 🙏

### 5/5 — Здорово

*2019-04-05, version 1.1*

Пользуемся в основном не этим приложением, а версией для двигателей Ево, тоже от этого разработчика. Но для старых двигателей - используем эту программу. Понравилось, что есть история, что можно выбрать один из нескольких источников погоды, что можно вполне сносно работать и без интернета, программа умеет работать со встроенным в телефон барометром и высотомером.
Лямбду рисует вроде верно, проверяли по сравнению с Аимом, как они это рассчитывают - непонятно, но очень круто.

### 5/5 — Sehr gut

### 5/5 — Must have

*2019-04-02, version 1.1*
