Defi Meter C vs QUAD

本アプリはDefi Smart Adapter WとBluetoothで接続して使用するアプリです。 Defi Smart Adapter WはADVANCE Control UnitやOBDと接続して使用する製品で、 ADVANCE Control Unitに取り込んでいる車両情報またはOBDの車両情報をBluetoothでiOS端末に送信するアダプターです。 Defi Webサイトに記載の注意点および使用方法を必ずお読みになってからダウンロードしてください。 必ずDefiにて動作確認が取れた携帯端末をご使用ください。 動作確認が取れている携帯端末につきましてはDefi Webサイトに記載しております。 Defi ADVANCEコントロールユニットまたはOBDに入力されているセンサーデータがメーターとして表示されます。 表示可能な機種は、車速、エンジン回転数、吸気圧、油圧、燃圧、油温、水温、排気温度、電圧、スロットル開度、吸気温度、ギアポジションです。 アナログメーター表示やデジタルメーター表示機種をタッチすると、切り替えできます。 本アプリはADVANCE CR/BFのデザインとマッチしたスタイルです。 アプリが正常に動作しない場合や、ご不明点等がありましたら、下記Defi Webサイトの問い合わせフォームよりご連絡ください。 　http://www.nippon-seiki.co.jp/defi/support/inquiry/

A GPS lap timer that works anywhere on Earth, and an integrated vehicle-dynamics G-force meter. Using nothing but your phone's sensors and GPS, it times laps and sectors while showing four-wheel weight transfer, G-forces and chassis attitude in real time. No extra sensors. ■ GPS lap timer Circuits, of course — but you can set a course anywhere in the world. Long-press the map to place start, finish and sector lines, and every crossing splits a lap and a sector automatically. Best lap, last lap and every sector time stay on the main screen, so you can see where you are finding time while you drive. Closed circuits and open point-to-point courses are both supported, so rally and hill-climb stages work too. Save as many courses as you like, set which direction counts as a crossing, and add as many sectors as you need. With no course set, the LAP button still times from where you stand. ■ One integrated meter Four-wheel load, the G-G diagram, yaw rate and roll/pitch on a single screen, right alongside the lap display. Everything you need while driving, in one place. ■ Four-wheel load monitoring Weight transfer is computed from G-forces and your vehicle specs, then shown at each corner as colour and numbers, so you can see whether you are using all of the tyre. Load falling shifts blue, load building shifts red. Delta/absolute and %/kgf are both switchable. ■ G-G diagram Lateral against longitudinal G, with the trail you actually drove and the envelope of the limit you reached. The envelope is where your car's grip runs out, drawn for you. ■ Understeer and oversteer alerts Measured yaw rate is compared against the theoretical neutral-steer reference to catch sharp yaw-rate changes in the transient, and the app calls them out by voice and colour. The axle that is losing cornering force is boxed, so you can tell instantly which end is going. Tune it with a scene (circuit / winding road) × sensitivity profile. ■ Data logger and viewer Record a session and review times, racing line and vehicle data afterwards. A track map coloured by speed, time-series charts of G, yaw rate and attitude, and the G-G diagram all follow one playhead. Understeer and oversteer segments are marked on the charts. Export to CSV to analyse the data in external tools. ■ Customisation Theme (dark / light) and accent colour, which channels appear in the readout column, the range of each meter, load display units, render rate and more. ■ Three steps to start 1. Enter your vehicle info (weight, CG height, wheelbase, track, weight distribution). It works on the defaults, but the more accurate you are, the closer the load readout gets to your real car. 2. Mount the phone rigidly, screen upright. 3. Run calibration once before you drive. No sensors handy? Settings has a "Play demo" mode that replays real recorded track data through every feature. ■ About the in-app purchase Lap timing, the data logger and viewer, understeer/oversteer alerts and UI customisation are Premium features, unlocked with a single payment. There is no subscription and nothing auto-renews. ■ Please read This app is a simulated monitor that estimates and displays vehicle attitude, load, G-forces and understeer/oversteer tendency from phone sensors and GPS. It is not a certified measuring instrument or a safety device. All values shown are approximate and are not guaranteed to be accurate real-world measurements. Load is not a load-cell reading; it is a computed estimate. Timing accuracy depends on your device's. This app is intended for competition use in closed environments such as race circuits. Watching the screen while driving is distracted driving and is illegal and punishable under applicable traffic laws. Never watch the screen while driving on public roads. If you use it on public roads you must comply with all applicable laws and do so entirely at your own risk.
