CNG Sequent fastness with BRC injectors and Zenith reducer

USEFUL
REFERENCES
For further information on
“SEQUENT FASTNESS” system, it
is recommended to refer to the
other handbooks and informative
documents published by BRC.
• Installer’s handbook.
It is the easiest way to obtain
fundamental, general information regarding the installation of
the SEQUENT FASTNESS
equipment.
Inside that, it is moreover
possible to find:
- knowledge about the working
principle and the structure of the
system,
- a detailed description of the
components which the system is
made up,
- indications about the assembly
of the mechanical part and electrical connections.
Modular Common Rail system for gas
• Software handbook.
It is the indispensable guide for
who wants to learn managing
the system by means of a
personal computer, realizing
mappings , programming the
ECUs, making diagnosys,
modifying the working parameters. It describes the working of
the “SEQUENT FASTNESS”
software, which runs on
Personal Computers, by driving
the user in the various steps of
each function.

electro-assisted valve
• 1 gauge with CNG resistive
pressure sensor
• 1 bag containing screws, nuts
and various fittings.
The present handbook results
particularly useful to the installer
when he decides to convert a
vehicle for which BRC has not
marketed the specific kits yet.
In this case it is therefore very
important that the installer knows
how to choose a basic kit and a
standard kit suitable to the vehicle
that is being converted, depending
on the number of its cylinders and
their location, the type of engine
(aspirated and supercharged) and
the power.
Zenith pressure reducer is
supplied with a Delta p (∆p) adjustment equal to about 2000 mbar.
If necessary, this value can be
changed between 1600 and 2500
mbar by the technician by acting on
the suitable screw.
As already referred to in
Chapter 1 of the Installer ’s
Handbook, we are herebelow
reporting for your convenience the
GENERAL composition of the basic
and the standard kits.
For an easy research, this
guide lists all the fed powers and
∆p values. Please note that the
guide only refers to CNG
Fastness Sequent System with
BRC injectors and Zenith
reducer.
The CNG Sequent Fastness
basic kit contains:
• 1 FLY SF ECU without cartography,
• 1 harness (BRC Injectors),
• 1 roll of copper or steel pipe,
• 8x15 Water pipe
• 1 ZENITH SEQUENT CNG
pressure reducer with gas
temperature sensor,
• 1 MAP CNG pressure sensor,
• 1 VM A3 /E “WP” Classic CNG
The CNG Sequent Fastness
standard kit contains:
• 3 (or 4, 5 or 6, depending on
the number of cylinders) BRC
gas injectors with respective
calibrated nozzles,
• 1 BRC injectors connection
rail, with fittings attached,
• 10x17 12x19 Gas pipe,
• 5x10,5 Gas pipe to be used on
the injectors and on the
pressure points,
• A bag containing: idling nozzle,
nylon Y piece, nuts, junctions
and “click” clamps for 5x10,5,
and 12x19 gas pipes, “click”
clamps for the pressure points.
It is obvious that both the basic
and the standard kits are available
in various configurations.
Listing the complete description
of all basic and standard kits
devised by BRC will be superfluous
and prolix. But, in the following
mechanical diagrams, referring to
the type of vehicle to be converted,
we indicate the necessary basic
and standard kits, inside which the
installer will find the suitable and
essential products for the conversion.
For the general electrical
connections it will be sufficient to
follow the wiring diagrams indicated
on each mechanical diagram.
Please remark that the representation of the products on the
mechanical diagrams is purely
indicative. The main products
present inside the standard kits are
distinguishable by GREY colour,
while the main products present
inside the basic kits are distinguishable with WHITE colour.

Application field
The “Open-collector” crankshaft sensor adapter is used on the vehicles converted with the SEQUENT
system that have a crankshaft sensor supplied with 5V and an amplified outlet referred to the ground,
only if it is necessary to activate the Timing advance processor inside the FLY SF ECU.
This particular type of crankshaft sensor of the vehicle is recognisable by the “square” output signal (the
traditional ones reproduce a sinusoid) that disappears when the wire connecting the sensor to the petrol
injection ECU is cut.
These sensors are generally assembled on all cars of the Volkswagen group (Audi, Seat, Skoda).
