STAR MAX – OBD CAN II Is a microprocessor based gas injection controller. It is mainly destined for modern cars, which have technologically advanced OBD II system with possibility of communication through digital serial CAN bus. It gives possibility of diagnosing OBD of original car's petrol ECU from the level of LPG controller's software. Besides signals from original's petrol injectors controller uses additionally information from car's OBD system (like vacuum, signals from both lambda probes, short and long term fuel trims) to determine amount of gas needed in the particular moment. Controller reads the parameters of mixture's correctors mentioned above and adjusts gas injectors opening times, to make the „Short Time Fuel Trim” and „Long Time Fuel Trim” values oscillate between values expected by the car's manufacturer. Thanks to its modern construction and highly efficient CPU it gives possibilities to fulfill strict emission exhaust norms, keeping the driving dynamic and performance identically as on petrol. In STAR MAX OBD CAN II controller the unique algorithms of controlling LPG injectors has been used. Injection opening time for each gas injector is being calculated individually, in real time, basing on injection opening time of petrol injector corresponding to it. Thanks to that solution efficiency and dynamics of driving on gas are practically identical like on petrol. Another advantage of that solution is the fact that controllers works without any problems with car's engines like HEMI (part of cylinders are being temporarily turned off during work), Valvetronik (constant value of vacuum in the inlet manifold) and cars which are having opening time differences between individual injectors (Subaru). STAR MAX OBD II can work with wide range of injectors: RAILGAS, RAIL, REG, MATRIX, MAGIC JET, VALTEK, PLANIJET, H***0, KEIHIN of impendency from 1 up to 6 Ohm. It is the smallest device on the market of sequential injection gas system, which can control up to 8 cylinders. **0% waterproof aluminum case dimensions are: **0 (length) x **0 mm (width) x *8 mm (thickness). Thanks to the anti-sustention protection devices build on the printed circuit board and latest technology of manufacturing with usage of the highest class of elements the system is completely non-failure. Controller, harness, switch, and pressure and temperature sensors are being tested twice carefully before they will leave the factory and warehouse. In effect we the customer and installer is happy due to trouble less, fine working for long time car gas installation. Software makes possible to adjust parameters of fuel supply system in very large scale. Besides the correction due the vacuum in the intake manifold, installer can adjust gas dosage regarding to RPM level. It is also possible to adjust mixture dosage for each cylinder separately and possibility of preheating the gas injectors before changeover.
