TECH DUO is a modern controller dedicated to 4-cylinder petrol engines with indirect fuel injection. It is built on a fast microprocessor and designed to meet the highest performance and functionality standards. Semiconductor petrol injector emulators ensure precise and reliable fuel switching and allow alternating petrol injections while operating on gas.

Mixture calibration can be done using a single slider, or — for advanced users — a full 3D map. The controller communicates with a digital RGB touch control unit, which can be freely programmed and customized to match the vehicle’s interior design.
