How to use:
1. Install the app and create a new engine profile, selecting IAME KZ1 or KZ2, carb type, fuel, and oil ratio.
2. Enable location to auto-fetch live weather or enter temperature, humidity, altitude, and pressure manually.
3. Tap Calculate to get recommended main jet, needle clip position, pilot circuit guidance, and air or mixture screw settings.
4. Apply the changes to your kart, run a few laps, then fine-tune using throttle response, plug color, or EGT readings if available.
5. Save the session with track name, conditions, and notes, then compare with previous setups to refine your baseline for future events.
