STAG-4 Q-BOX BASIC is the first of our new-generation controllers for sequential autogas injection in vehicles powered by four-cylinder engines with multiple fuel injection.
The unit design is based on a modern, high-performance 32-bit microprocessor enabling very precise control of autogas feeding, rapid response to varying engine parameters and measurement of petrol injection time.
The hardware platform offers a range of useful functions, including the possibility of change (to) the injection sequence, support for wireless Bluetooth communication and reading of engine rpm on the basis of petrol injection signals. The design allows for the addition of new functions and extensions of the QBOX series.
The compact, light and robust housing with its ergonomic arrangement of functional elements allows faster and easier wiring up as well as installation in any position within the engine compartment. The high-quality plastic material used for the housing has been examined as required, with the use of mechanical strength, climatic and thermal shock tests. It demonstrates a high resistance to applied forces and weather conditions. A housing base plate made of stainless steel guarantees a high corrosion resistance and emphasizes the unique look of the housing.

STAG-4 Q-BOX BASIC is manufactured on the basis of the latest technology and top quality components tested in laboratories at the AC Research and Development Center in line with automotive standards. The ideal selection of components and the innovative 32-bit signal processor for autogas injection control guarantees precise and instant fuel dosage and improve the economics of driving on autogas. STAG 4 QBOX BASIC is an optimal solution for modern engines, ensuring their long life, failure-free operation, safety and comfort.
