## What is Y?

■Brief Description
Y-TRAC is an application that collects and analyzes data through the 2015-2020 model YAMAHA YZF-R1 / R1M equipped with CCU. Ride analysis can be performed by matching position information with vehicle condition in real time.

■Detailed Description
Let's ride the circuit together! Improve your time by carefully analyzing ride characteristics and vehicle condition!
Y-TRAC is a log viewer application for viewing vehicle information collected in the CCU (* 1). Many kinds of vehicle information are displayed visually in an easy-to-understand graph, such as vehicle speed and engine speed, accelerator opening, banking angle and brake pressure, as well as various types of control effects. In addition to vehicle information, position information is recorded simultaneously in the log data stored in the CCU. Due to this synchronization of position information and vehicle condition, you can quickly pick up information such as braking point at corner entry, brake pressure, vehicle speed, line, banking angle at turn, and throttle condition at exit. Since the graph displays each lap, you can easily understand the characteristics of a good line. Find a way to improve your lap time through careful study of the app's features. 
* To record logs of laps to the CCU, it is necessary to dictate the record line to the CCU in advance.
* 1) Communication control unit (2015-2020 model year YAMAHA YZF-R1M equipped with data logger unit)

6) Split laps
When comparing different data, you can re-set the lap to fit in one record line.

### 5/5 — Au top

*2025-05-05, version 2.6.8*

J’utilise l’application depuis 2019 et je la trouve très simple à utiliser. Elle me permet d’avoir mes temps au tour ainsi que toute le télémétrie de la moto. Elle reste beaucoup plus lisible sur iPad mais je l’utilise aussi sur mon iPhone sans souci.

### 5/5 — App fantastica

*2021-03-13, version 2.6.3*

Peccato non ci sia per Windows, da telefono è un po’ piccolo e non mi pare il caso di comprare un tablet per una singola app

### 1/5 — Doesn’t communicate

*2020-09-12*

After recent update, unit will not download logs from CCU. Constantly says not connected and to check wifi connection when it is in fact connected.

### 5/5 — iPhone,iPad双方で使えて便利

*2020-09-09*

サーキットではスマホでデータを吸い上げて、家でiPadを使って解析ができて便利です。
トラックモードのデータの再生を1周だけでなく連続して何周も再生できると嬉しい。
2KS-85721-70のハーネスの単品販売がないのが残念。単品で入手できればもっと使用範囲が広がる。
汎用ファイル形式にエクスポートできるとなお良いと思います。
今後に期待しています。

### 1/5 — No conn

*2019-10-24*

Doesn’t connect to the CCU. Not working on iOS 13.   Y-settings works fine but y-trac doesn’t.  Can anyone help?

### 5/5 — Fonctionne très bien

*2019-06-01, version 2.4.2*

Les commentaires datent des anciennes versions de l’application.

### 1/5 — THE LATEST UPDATE BROKE THE APP ALL IT SAYS IS REGISTER CCU

*2019-04-14*

THIS APP IS TOTAL GARBAGE THE LATEST UPDATE BROKE THE  APP AND NOW IT TELLS ME TO REGISTER THE CCU . SERIOUSLY YAMAHA WY DID YOU EVEN UPDATE THE APP. IT WAS WORKING JUST FINE A COUPLE WEKS AGO. 
 It keeps telling me to update the ccu registration and i have done  that  already .i literally need the data log . I am seriously thinking about a lawsuit because the whole reason i got the bike was to use the data logger

### 1/5 — Bug

*2019-04-01, version 2.4.1*

Le téléchargement des données ne fonctionnent fonctionnent plus depuis la mise à jour. Le transfert iPad vers la moto (ligne d’arrivée du circuit) est ok mais pas l’inverse on ne peut pas récupérer les map

### 1/5 — Rovina le qualità della moto

*2018-09-18, version 2.4*

Una moto eccezionale con un’acquisizione che potrebbe renderla simile a una moto gp ma che funziona in modo terribile. 
La App spesso va in crash, non scarica correttamente i dati a volte li perde, insomma rovina qualcosa che potrebbe rendere la moto ancor più accattivante. 
Inoltre non è disponibile per iPhone.
Da rivedere rapidamente visto il costo dell’ acquisizione. 
Non a livello Yamaha

### 1/5 — Lame

*2018-08-18*

Not very good analysis features. You can export your data but not import it which is the definition of pointless. Don’t waste your money the CCU if you want data analysis.
