USEFUL REFERENCES
For further information on “SEQUENT” 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 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” software, which runs on Personal Computers, by driving the user in the various steps of each function.

PRESENTATION
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. 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. The LPG basic kit contains: • 1 FLY SF ECU without cartography, • 1 harness, • 1 roll of ø 6 or ø 8 copper pipe, • 16x23 Water pipe • 1 GENIUS SEQUENT LPG pressure reducer with thermistor gas temperature sensor, • 1 cartridge filter for gas “FJ1” • 1 P1 - MAP or P1 - MAP Turbo pressure sensor, • 1 LPG “ET98 FLY – INJ WP” solenoid valve, • 1 bag containing screws, nuts and various fittings. The CNG basic kit contains: • 1 FLY SF ECU without cartography, • 1 harness, • 1 auxiliary harness, • 1 roll of copper or steel pipe, • 8x15 Water pipe
• 1 GENIUS SEQUENT CNG pressure reducer with thermistor gas temperature sensor, • 1 cartridge filter for gas “FJ1”, • 1P1 - MAP CNG 2,5-4 bar pressure sensor, • 1 VM A3 /E “WP” Classic CNG electro-assisted valve • 1 gauge with CNG resistive pressure sensor • 1 bag containing screws, nuts and various fittings. The standard kit contains: • 4 (or 3, or 6, depending on the number of cylinders) gas injectors with respective calibrated nozzles, • 1 injectors connection rail, with fittings attached, • 10x17 Gas pipe, • 4x10 Gas pipe to be used on the injectors, • 4x10 Gas pipe to be used on the pressure points, • A bag containing: idling nozzle, nylon Y piece, nuts, junctions and “click” clamps for 4x10 and 10x17 gas pipes, “click” clamps for the pressure points, M8x1 cap for any RAIL closure. It is obvious that both the basic and the standard kits are available in various configurations. In the first case we have devised in fact basic kits, that can have a 800 or 1200 or 1500 mbar Genius reducer, the P1MAP or P1 Map Turbo sensor, the Normal or Super solenoid valve etc. In the case of the standard kits we have conceived packagings in which the number of injectors and the shape of the Rail varies depending on the number and the typology of the cylinders of the vehicle, etc. 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 3
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.
