T.A SIGAS 2.4+ controller


SIGAS 2.4+ is the first Argentinan LPG/CNG system which meets the requirements of stringent EURO 6 emissions standards.

TA 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 TA 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.
