INTRODUCTION
Dear Customer,
We would like to thank you for choosing our product and we wish to provide you with some information about
this entirely unique and exclusive product, the FAST Box.
In over 50 years of operation, the Sito Group has achieved a series of goals and advances that have con-
tributed towards building a position of leadership in the aftermarket motorcycle exhaust system sector.
The most recent advance is called LeoVince Electronic Systems, a completely new department reporting to
LeoVince’s Research and Development Department. LeoVince Electronic Systems was created for the develop-
ment of electronic control units (ECUs) for engine management, to be used, initially, in conjunction with our own
LeoVince X3 (off-road) systems.
The goal of LeoVince electronic Systems is to create a unique and optimized “system”, i.e. producing an exhaust
system and an ECU, the latter being configured for use with both the exhaust and the motorcycle.
For the initial offering of the FAST Box, motorcycles designed for motocross, enduro and supermotard have been
chosen, ones specifically using a 4-stroke single cylinder engine with carburetor, so the FAST Box can be used
in conjunction with the LeoVince X3 line of exhaust systems.
In this case, the ECU replaces the existing OEM ECU and is not used in tandem with the original, as it is pos-
sible to do on scooters and street bikes with fuel injection.
The LeoVince Electronic Systems engineers have designed and produced the FAST Box entirely within the com-
pany in close collaboration with the technicians who produce our exhaust systems, thereby obtaining a highly
focused and integrated product.
The ECU operates in extremely demanding mechanical, thermal and environmental conditions therefore TÜV
Italia has carried out all the inspection tests, guaranteeing its reliability.
After passing the bench tests, the definitive prototypes were handed over to users and professional riders to
carry out a series of tests “in the field”. Then, after some final adjustments, the commercial product was final-
ized and production begun.
This product represents the first steps in a diversified project, with the development program already looking
towards scooters, single and multi-cylinder fuel injected motorcycles.
Welcome to the FAST age!

2. WARNINGS
This manual has been written by SITO GRUPPO INDUSTRIALE S.p.A. for use by qualified personnel. Obviously, it would
not be possible, in a single manual, to provide complete mechanical training. It therefore goes without saying that any-
one who uses this text to carry out installation and work on the FAST ECU, must have the knowledge and the basic tech-
niques needed for working on motor vehicles. If this condition is not met and if all the information in the manual is not
adhered to, any attempt to use FAST products on the motorcycle may make the product unfit for use and/or dangerous.
SITO GRUPPO INDUSTRIALE S.p.A. is constantly seeking to improve all its products. Modifications or significant changes
made will be brought to the attention of all the SITO Authorized Retailers and, where applicable, will be inserted into fur-
ther editions of this manual.
NOTE: The drawings and the specifications are subject to change without prior notice.
SITO GRUPPO INDUSTRIALE S.p.A. is not responsible for any damage arising from attempts to tamper with the FAST ECU
or from improper use of it.
The FAST ECU has been designed and produced for motorcycle competitions and its use on the public road is not per-
mitted.
Carry out installation of the FAST ECU with the engine switched off, and if the battery is installed, disconnect it.
Pay particular attention when attaching the ECU, be sure to find an adequate support point.
Pay particular attention, when positioning the wiring, avoiding contact with excessively hot parts, avoiding excessively
tight bends, and avoiding critical points where there could be rubbing or abrasion of the cables.
BEFORE BEGINNING INSTALLATION READ THIS MANUAL CAREFULLY

4. IMPORTANT INFORMAITON
Information in this manual that is of critical importance is marked with the following symbols:
A danger symbol means BE CAREFUL! YOUR SAFETY IS AT RISK!
Failure to observe the instructions that follow this symbol could cause serious injury, if not
the death of the rider, people nearby, or people engaged in repairing the motorcycle.
This indicates special precautions that must be observed to avoid damage to the
motorcycle.
A NOTE provides key information aimed at facilitating installation instructions or making
them clearer.
5. PREPARING TO INSTALL
Before installing the FAST ECU, follow some simple recommendations in order to carry out a better job and optimize instal-
lation time:
1) Only start work when the motorcycle is cold;
2) Remove every trace of dirt, mud, dust and debris before starting to remove or dismantle parts;
3) Use clean tools and equipment;
4) When removing parts, clean them and put them on a tray, keeping them in the order in which they were removed. This
allows you to save time when re-assembling and to install all the parts correctly;

6. WIRING OUT
The following are some guidelines for cable and wiring layout.
1) A loose wire or cable can be a safety risk. After attaching them, check all wires to make sure they are properly secure.
2) Do not squeeze wires against the soldering iron or the end of the clamp when soldering clamps are being used.
3) Secure wires and cabling to the frame with straps. Tighten the straps so that only the insulated surfaces come into con-
tact with wires and wiring.
4) Arrange the wiring so that it is neither excessively tight or loose.
5) Arrange the wiring so as to avoid sharp edges or corners. Also avoid protruding heads of bolts or screws.
6) Protect wires and wiring with electrical tape or ducts if they come into contact with sharp edges or corners. Clean the
surface thoroughly before applying the tape.
7) Do not use wires or cables with broken insulation. Repair them with electrical tape or replace them.
8) Keep wiring away from exhaust pipes or other high temperature areas.
9) After attaching the connectors, check each piece of wiring to make sure it does not interfere with any moving or slid-
ing part.
10) Check that the wiring positioned along the handlebars is neither too tight, too loose or pinched and must not inter-
fere with adjoining or surrounding parts in all steering positions.
11) After completing the layout check that the wiring is not twisted or bent.
12) Check electric wires and the connection elements for any stains, rust, dampness, etc. If there are traces of dampness
dry with a fan. If there are rust/stains, connect and disconnect the parts several times.
13) Clean the connectors thoroughly before attaching the FAST wiring.

9. REMOVING THE FUEL TANK
Before removing the fuel tank make sure the tap is in the OFF position, then disconnect the fuel hose from the engine
(Position 1, Figure 3) and remove the nut that keeps the tap fastened to the frame (Position 2, Figure 3). Next remove the
nut that attaches the fuel tank to the frame (Position 1, Figure 3a) and any rubber fastening bands.
During this operation a small quantity of fuel may come out.
NOTE:Before removing the hose, place some rags under the removal point in order to dry up any fuel leakage.
Once the tank is removed place it on a flat surface in the upright position.

10. REMOVING THE ORIGINAL WIRING
Disconnect the original Yamaha connectors positioned under the side panels and under the fuel tank that have just been
removed, as shown in Figure 4 and Figure 4a.
NOTE: check the electric wires and the connection elements, checking for the presence of stains, rust, dampness etc. If
there are traces of dampness, dry with a fan. Where there are rust/stains, connect and disconnect the connectors sever-
al times. If the battery is present disconnect it before carrying out the operations to remove the original wiring.
Disconnect and remove the original ECU, positioned above the front fender as shown in Figure.
NOTE:Thoroughly clean the connectors removing traces of dust, mud or debris.
