  The terminal device 4 is a general-purpose computer and includes an input unit 4a such as a keyboard and a display unit 4b such as a display. As described above, the terminal device 4 is connected to the server device 5 via the Internet 51.

  The server device 5 is connected to and accessed from the plurality of terminal devices 4 via the Internet 51. The server device 5 has a memory 100 as storage means. The memory 100 stores a recommended air-fuel ratio map a in which the air-fuel ratio is set for each race course, and a recommended ignition timing map b in which the engine ignition timing is set for each race course. Each recommended air-fuel ratio map a and each recommended ignition timing map b are individually created for each predetermined weather condition and temperature condition set in advance. In this embodiment, two types of weather conditions, weather 1 and weather 2, and three types of temperature conditions, temperature 1, temperature 2, and temperature 3, are set in advance.

  4A is a tree diagram showing the classification of the recommended air-fuel ratio map a stored in the memory 100 (see FIG. 1), and FIG. 4B is stored in the memory 100 (see FIG. 1). It is a tree diagram which shows the classification | category of the recommended ignition timing map b. Note that the recommended air-fuel ratio map suitable for course 1 is map a1, the map suitable for course 2 and course 3 are map a2 and map a3, respectively, and the recommended ignition timing map suitable for course 1 is map b1 and similarly. Those suitable for the course 2 and the course 3 will be described as a map b2 and a map b3, respectively.

  As shown in FIG. 4A, the recommended air-fuel ratio map a1 suitable for the course 1 is individually created for each weather and temperature, and the memory 100 (see FIG. 1) has a total of six types of a11 to a16. A recommended air-fuel ratio map a1 is stored. Similarly, the recommended air-fuel ratio map a2 suitable for the course 2 and the recommended air-fuel ratio map a3 suitable for the course 3 are also created individually for each weather and temperature, and in the memory 100 (see FIG. 1), a21 to A total of six types of recommended air-fuel ratio maps a2 and a3, a26 and a31 to a36, are stored.

  On the other hand, as shown in FIG. 4B, recommended ignition timing maps b1, b2, and b3 suitable for the course 1 are similarly created for each weather and temperature, and b11 is stored in the memory 100 (see FIG. 1). A total of six types of recommended ignition timing maps b1, b2, and b3 of b16, b21 to b26, and b31 to b36 are stored.

  As shown in FIG. 5, the recommended air-fuel ratio maps a11 to a16, a21 to a26, a31 to a36 and the recommended ignition timing maps b11 to b16, b21 to b26, b31 to b36 have the same conditions (the same course, the same Weather conditions and the same temperature conditions) are associated with each other and stored in the memory 100 as a map set. For example, the recommended air-fuel ratio map a11 and the recommended ignition timing map b11 suitable for the conditions of course 1, weather 1, and temperature 1 are stored as a map set M11, and are suitable for the conditions of course 1, weather 1, and temperature 2. The recommended air-fuel ratio map a12 and the recommended ignition timing map b12 are stored as a map set M12. In this way, the memory 100 stores the map sets M11 to M16, M21 to M26, and M31 to M36 of the recommended air-fuel ratio map a and the recommended ignition timing map b that are associated with each condition.

  The server device 5 also stores the initial air-fuel ratio map A and the initial ignition timing map B stored in the ECU 3 of the racing straddle-type vehicle 2, the recommended air-fuel ratio map a and the recommended ignition timing for any race course. A program P for rewriting the map b is stored.

  6A shows a recommended air-fuel ratio map a11 suitable for the course 1, weather 1, and temperature 1, as an example of the recommended air-fuel ratio map a, and FIG. 6B shows the course 2, weather 1, A recommended air-fuel ratio map a21 suitable for a temperature of 1 is shown. In the maps a11 and a21, suitable air-fuel ratios are set for each engine speed and each throttle opening. Here, it is assumed that course 1 is a course with a long straight and course 2 is a course with a short straight. In such a case, the air-fuel ratio X1 under the condition of the engine speed 2500 (rpm) and the throttle opening 10 (°) in the map a11 is lower than the air-fuel ratio X2 under the same conditions in the map a2 ( The fuel ratio is set to be high). Further, even when the course 1 is a course with a steep slope and the course 2 is a course with a gentle slope, X1 is similarly set to be lower than X2 (the fuel ratio becomes higher).

  FIG. 7A shows a recommended ignition timing map b11 suitable for the course 1, weather 1, and temperature 1, as an example of the course-specific ignition timing map b, and FIG. 7B shows the course 2, weather 1 1 shows a recommended ignition timing map b21 suitable for the case where the temperature is 1. In the maps b11 and b21, suitable engine ignition timing is set for each engine speed and each throttle opening. Here, as in the case described above, if course 1 is a course with a long straight and course 2 is a course with a short straight, engine speed 2500 (rpm) and throttle opening 10 in recommended ignition timing map b11. The ignition timing Y1 under the condition (°) is set to be later than the ignition timing Y2 under the same condition in the map b21. When course 1 is a course with a steep slope and course 2 is a course with a gentle slope, Y1 is set to be earlier than Y2.

  The above is the configuration of the engine setting system 1. Next, the operation of the engine setting system 1 will be described.

  First, a user who knows the type of race course, weather conditions, and temperature conditions at the site (for example, a race venue) inputs these condition data into the input means 4 a of the terminal device 4. In the present embodiment, the following description will be made assuming that the condition 1, the course 1, the weather 1, and the temperature condition 1, is input.

  The terminal device 4 transmits a designation signal designating the condition 1 to the server device 5 via the Internet 51. The server device 5 searches the memory 100 for a map set M11 (a set of the recommended air-fuel ratio map a11 and the recommended ignition timing map b11) suitable for the condition 1 from the memory 100 and transmits it to the terminal device 4.

  Further, when the terminal device 4 does not store the program P for rewriting the initial air-fuel ratio map A and the initial ignition timing map B stored in the ECU 3 to the recommended air-fuel ratio map a11 and the recommended ignition timing map b11 of the map set M11, the user Inputs a command requesting the program P to the terminal device 4. The terminal device 4 receives the instruction and transmits a request signal to the server device 5. In response to the signal, the server device 5 transmits the program P stored in the memory 100 to the terminal device 4.

  The terminal device 4 receives the initial air-fuel ratio map A and the initial ignition timing map B stored in the ECU 3 based on the program P acquired this time or the previous time, and the recommended air-fuel ratio map a11 and recommended ignition received from the server device 5. A rewrite signal for rewriting the time map b11 is transmitted to the ECU 3. When the ECU 3 receives the rewrite signal from the terminal device 4, the ECU 3 rewrites the initial air-fuel ratio map A and the initial ignition timing map B into the recommended air-fuel ratio map a11 and the recommended ignition timing map b11 of the map set M11.

  As described above, according to the engine setting system 1, the user can easily obtain the recommended air-fuel ratio map a11 and the recommended ignition timing map b11 suitable for the course, weather, and temperature conditions in the field. It becomes. Further, the user can rewrite the initial air-fuel ratio map A and the initial ignition timing map B stored in advance in the ECU 3 to the recommended air-fuel ratio map a11 and the recommended ignition timing map b11 by a simple operation. Therefore, according to the engine setting system 1, a suitable engine setting corresponding to the race course, weather, temperature, and the like can be easily performed in the saddle riding type vehicle 2 for racing even by a person with little experience.

  Further, according to the engine setting system 1, the rewriting program P can be quickly acquired via the Internet 51 by a simple operation using the terminal device 4. Therefore, it is not necessary for the user to prepare the rewriting program P in the terminal device 4 in advance, and the user can obtain it at a race venue or the like. Therefore, according to the engine setting system 1, in the saddle riding type vehicle 2, a suitable engine setting corresponding to the race course can be easily and quickly performed even by a person with little experience.

  Further, the memory 100 of the server device 5 stores a recommended air-fuel ratio map a11 and a recommended ignition timing map b11 in association with each other as a map set M11. A map set M1 suitable for condition 1 is transmitted to the terminal device 4 by a designation signal indicating condition 1 from the terminal device 4, and the initial air-fuel ratio map A and the initial ignition timing map B stored in the ECU 3 are map sets. The M1 recommended air-fuel ratio map a11 and the recommended ignition timing map b11 are rewritten. Thus, the user can easily change the settings in the air-fuel ratio control and the engine ignition timing control of the ECU 3 only by designating each condition (course, weather, temperature, etc.). Therefore, according to the engine setting system 1, even an inexperienced person can change the engine setting of the saddle riding type vehicle 2 by a simple operation.

  In the engine setting system 1, the server device 5 is provided with various maps on the condition of course, weather, temperature, etc., thereby performing engine setting of the saddle riding type vehicle 2 for racing. However, the types of maps are not limited to these. Therefore, a recommended map suitable for the other conditions may be created and the existing map may be rewritten. It is also possible to provide various maps only for the course, and make engine settings suitable for each race course regardless of the weather, temperature, etc.

  In the engine setting system 1, the initial air-fuel ratio map A and the initial ignition timing map B are rewritten to the recommended air-fuel ratio map a and the recommended ignition timing map b corresponding to each condition. However, the map that can be rewritten to perform the engine setting is not limited to this. Therefore, for example, a map such as the fuel injection amount and the intake air amount may be rewritten.

  The engine setting system 1 can be applied not only to the motocrosser ECU 3 but also to other types of motorcycles 3 (including motorbikes, scooters, etc.). Further, the race straddle-type vehicle 2 according to the present invention is not limited to a motorcycle, and may be, for example, an ATV such as a four-wheel buggy.

  Further, the terminal device 4 in the engine setting system 1 may not be a general-purpose computer. For example, a mobile phone capable of data communication using the Internet 51 may be used as the terminal device 4.

  As described above, the present invention is useful for an engine setting system.
