Yoshimura EMS controller

    
 
Yoshimura EMS controller is a stand alone unit that enables quick and simple adjustment to the OEM fuel and timing maps to optimise engine performance, for race and road bikes. Adjustments can be made to over 200 different points on the fuel and timing tables based on throttle position and RPM. The controller also stores 3 separate fuel and timing tables on board, allowing the ultimate in tunability and flexibility.

Installation requires only about an hours worth of time and because we use OEM connectors to plug into the stock wiring, there is no cutting or splicing required.
  
  Yoshimura produce a range of optional accessories to compliment and enhance the EMS controller.  
  Clutchless Shifter
The Clutchless Shifter allows the rider to make up-shifts without the use of the clutch and without the need to roll off the throttle. The system senses when the rider initiates an upshift and cuts fuel delivery to allow the transmission to slide into the next gear.
 
  3-Way Map Switch
The 3-Way Map Switch allows the user to switch between any of the three stored fuel and timing tables in the EMS controller. This can be done while the bike is running. There is no need to shut down the motorcycle. The map files that are provided by Yoshimura R&D of America are formatted so that Table 1 is the base map, Table 2 is 5% richer, and Table 3 is 5% leaner. instantaneous. However, the user can format them any way they please. For example Table 1 can be the base map, Table 2 can be the track map, and Table 3 can be a nitrous oxide map. The switch from one table to the next is 		 

Extension Cable
The Extension Cable Kit allows the rider to mount the EMS communications port to the exterior of the motorcycle. This means that there is no longer a need to open the rear storage compartment to plug the communications cable in. All that is necessary is to unscrew the watertight cap and plug in. This kit is ideal for racers using aftermarket, racing bodywork that may not provide easy access to the EMS. This accessory does require drilling.

Shift Light
The Shift Light is a high-intensity LED that is mounted to the instrument cluster via a carbon fiber or aluminum bracket that is designed for each motorcycle model. The software allows the user to set precisely the RPM that the light will come on. The light also has a 2 stage feature that includes a flashing warning that can also be set by the user for a specific RPM.

Accessory Hub
The EMS Accessory Hub allows the EMS to control and communicate with the optional EMS Accessories. It is required for any of the above accessories.

  
       
 

Gear Dependent Map Offset
The Gear Dependent Map Offset, utilising the OEM gear position sensor, allows the user to trim the base map to suit each gear. The user can add or subtract fuel and advance or retard the timing for each gear and for each of the 3 stored map tables. For example the user can retard the timing 5 degrees and add 5% more fuel to 6th gear in fuel and timing table 1. At the same time fuel and timing table 2 and table 3 can be left unmodified
