SDI – Characteristics (1) What’s common with Sequent family product? LPG Injection in the manifold (Port Fuel Injection) vapour phase phased sequential injection Up to 6 cylinder naturally aspirated and supercharged engines Sequential change-over (BRC patented) Petrol injectors cutting and emulation integrated in gas ECU ECU programming and system diagnostic with notebook OEM characteristics for gas components Integrated diagnostic to allow an easy check of the system

SDI – Characteristics (2) What’s new compared with others Sequent family products? New gas ECU specially designed for petrol direct injection engines. New strategies to create a perfect integration with the petrol engine management and diagnostic. Petrol injectors cutting and reading though three wires. Petrol rail pressure reading in gas mode. Now available for stoichiometric engines Possibility to use petrol during gas mode to optimize the integration with petrol management and diagnostic and to avoid problems with petrol injectors

SDI – The Components LPG tank and Europa 2 multivalve ET98 solenoid valve Pressure regulators: Genius MB – Genius Max Vapour phase filter FJ1 HE BRC injectors SDI dedicated gas ECU SDI dedicated harness Gas injector rail with gas temperature sensor Gas pressure sensor New change-over switch

SDI – Diagnostic on PC Correlated data Suggested actions Error erase Errors calibration Automatic report Errors reading

SDI-Installation 4 e 6 cylinders dedicated kits Dedicated instructions and calibrations available in BRC web site
