Version 1.6 • Apple Watch, widgets and Live Activity: your main jet for right now on your wrist, on the lock screen and in the Dynamic Island throughout your track day. • Track mode: your jetting large and high contrast, to read it in full sun with your helmet on, with the conditions it is worked out from. And dark mode throughout. • Alerts when the weather changes enough to change the main jet: "Air density has dropped by 1.8 % since your last calculation". • Fuel: 98 E5, E10, E15, ethanol-free, CIK-FIA or race fuel, and the jetting is corrected for it. • Carburettor icing warning, using the criterion of civil aviation. • Fuel and oil mix calculator. • When you fetch the weather, the app detects the track you are at. 144 tracks in 22 countries, now including the United States. • Logbook synced through iCloud, and your jetting shared with your mechanic as a link or a QR code. • Location also works on iPad without GPS and indoors. • Report a problem and rate the app, from Results and from Help. IN EARLIER VERSIONS • 1.5: KK3 engine (2023-2025 homologation); setup logbook with ratings for low, mid and high; track database with the altitude of the track itself; the weather station inside Conditions; your jetting as an image card. • 1.4: KK1R calculation model adjusted after dyno testing.

Version 1.5 NEW ENGINE • KK3, 2023-2025 homologation. Modena's current flagship in KZ, with its own jetting: it shares neither top end nor crankcase with the KK2. 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 corrected 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 is now at the top of Conditions, next to the values you type in. They were two screens for one job. • The altitude is always stated, including when it could not be obtained. TRACKS • 112 tracks with their altitude, taken from the track itself and not from 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 calculated as 25, and 0 % humidity as 50. • The location screen never worked: the system had stopped reporting the position years ago. • Fine tuning on one setup leaked into the other three. • Rating the app took you to another app's page. • The app was drawn scaled up from a smaller canvas instead of at the phone's real resolution. • Temperature, pressure and humidity were clipped against the edge of the screen. • GPS altitude was discarded at sea-level tracks, and silently lost when applying the station data. • Long station names arrived truncated.
