ALEX IDEA controller

ALEX IDEA is a sequential gas injection in the vapor phase for petrol engines with direct fuel injection.

Modern solutions used in the ALEX IDEA controller enable the conversion of popular engines with direct fuel injection – the system can be adapted to most cars equipped with electromagnetic injectors. It stands out for above average fuel economy used for cooling and lubricating injectors petrol. The specially developed IDEA control algorithm consumes only about 5-15% of gasoline, while other installations of this type available on the market require about 20-30% of fuel to be injected.

The ALEX IDEA System is the Product of the Year 2018 according to autoEXPERT magazine.
