SIGAS 2.4+ is a sequential gas multipoint injection system appropriated for 3 and 4 cylinder engines.
The SIGAS 2.4+ unit reads the injection times calculated for the original control unit, applies the necessary corrections for the new fuel, CNG/LPG, and it activates the injectors. This feature makes the performance similar to the one programmed by the vehicle manufacturer. SIGAS 2.4+ is the only Auto Gas System that works on injection based strategy instead of MAP based strategy.
SIGAS 2.4+ controller is the most advanced computer unit controlling the sequential gas injection, in the ECU class with 32-pin link. This LPG/CNG controller is designed for vehicles with a simple and extensive indirect fuel injection systems. The innovatory algorithm of SIGAS 2.4+ controller, precisely adjusts the dose of gas to the operating conditions and engine load in the full range of his work, thus reducing gas consumption. The connection of a standard OBD interface gives installers the ability to collect OBD map Adaptation, injection time map of RPM and collector pressure and precise regulation of injection times, the RPM, collector pressure, temperature and gas pressure – it is a unique solution in this class of controllers.
