Yoshimura EMS
Controller is a stand alone unit that allows the
rider to adjust the OEM fuel and timing maps to optimize the engine
performance of their motorcycle. 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.
Maps developed by Yoshimura are supplied on the included CD-ROM.
Communication is via an easy to use software package utilizing a
graphical interface. All that is necessary to run the software is a PC
running Windows 95 or better and an open serial port. Installation on
the motorcycle requires only basic hand tools and about an hours worth
of time. Because we use OEM connectors to plug into the stock wiring
there is no cutting or splicing required. This also makes for a very
clean and professional looking installation.

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.

The amount of time that the fuel is cut can be
changed in the software. Typically the amount of time is in the 40-
60 millisecond range. The user can also set an rpm where the
system activates so that shifts at lower speeds will require the use of the
clutch.Normal shifts, using the clutch, can be executed while the system is
activated with no detrimental effect. This Accessory will also take
advantage of the GPSO to allow kill times to be set for each gear.
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.
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.
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 instantaneous.
Gear Dependent Map Offset
The Gear Dependent Map Offset, utilizing 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.
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. |
