Himawari CIRCUIT vs G

Himawari Circuit turns a day at the track into something you can look back on. It times your laps with GPS and records your driving line, speed and G-force together. After the session you can see, on the map, where you were quick and where you lost time. AUTOMATIC LAP TIMING Every time you cross the control line, a lap is recorded, along with sector times, top speed and average speed. Each lap time is announced out loud, so you never have to look at the screen while you drive. DRIVING LINES YOU CAN COMPARE Your line is drawn on the map, colored by speed or by G-force, so you can see where you are on the power and where you are not turning. Lay your own earlier runs over it, or line up runs from friends in the same group. In replay, up to four cars move at once, so you can watch the gap open up. SESSION VIDEO Record with your phone as you drive and play it back with your telemetry over it. Only your best lap is kept, and it never leaves your phone. YOUR SESSIONS ARE KEPT FOR YOU Sessions upload automatically when you finish. With no signal they stay on your phone and go up once you are back online. VEHICLES AND TIRES Record sessions per vehicle, with maintenance records and tire details, so you can trace how a setup changed your times. WITH YOUR FRIENDS Create a group to share sessions and leaderboards with its members. Live timing shows where your friends are on track, and their lap times, as they drive. EXTERNAL GPS RECEIVERS Works with RaceBox, DigSpice IV and the self-built Himawari GPS. A phone's built-in GPS updates about once per second; an external receiver updates far more often, which makes lines worth comparing.

WHERE YOU LOSE TIME — A G-BOX SIGNATURE FEATURE Open a lap and G-Box shows on the map which corners cost you time and how many tenths. No digging through telemetry graphs: it's fully automatic, right on your iPhone. Works with G-Box recordings and sessions from RaceChrono, AiM, MoTeC, TraqMate or Race Navigator. The benchmark is your own car on your own tires: the best pass through each corner from that car's fast laps (within 3.5% of the best) on the same track that day — not someone else's record. Tap a marker for the cause in plain words (braking too early, a slow exit) and what to do on the next lap. "Compare with lap N" puts the faster lap on the graph and map in one tap. Created by a professional racing driver and instructor. VIDEO WORTH SHARING Record with iPhone cameras or connect a GoPro. G-Box overlays lap time, speed, G-forces, track map and RPM on your video. Pick a race-car style dash or a vertical layout for social media. On supported iPhones, film both cameras at once: the road and the driver. ALL ON ONE IPHONE 25 Hz Fusion combines the iPhone's GPS and motion sensors to calculate a smooth driving line between GPS fixes, with no external receiver. These are calculated positions, not 25 Hz satellite measurements; results depend on GPS reception and phone mounting. Add a compatible OBD adapter, such as OBDLink MX+, for RPM, estimated gear and power, or an external GPS receiver: G-Box, RaceBox Mini, Mini S and Micro, and selected Dragy models. COMPARE YOUR LAPS • Automatic lap timing, live delta, sectors and predicted lap time • Every corner in one table: this lap, the day's best pass and the difference in braking, turn-in, apex and exit speed • Speed, G-forces, RPM and delta on synchronized graphs and map, against any lap from any session on the same track • Friction Circle and a theoretical best lap from your strongest sectors • Car class from power-to-weight and tire grip: performance points, SPORT to GT4, and leaderboards by track • Session replay on 2D and 3D maps YOUR DATA, YOUR WAY Import sessions from RaceChrono, Harry's LapTimer, VBOX, Race Navigator, MoTeC, AiM and TraqMate. Export to GBO, CSV, VBO, GPX and NMEA. TRY IT BEFORE YOUR TRACK DAY Open the included Nürburgring Nordschleife demo lap (8:06) to explore maps, graphs and lap timing before your first session.
