Mapecu3 [portable] | Extended ⚡ |

Newer versions of the hardware support flex-fuel tuning, adjusting engine parameters based on the ethanol content of the fuel.

As technology progresses from mechanical linkages to fly-by-wire and finally to AI-driven predictive engine management, the legacy of MAPECU3 remains: precise, reliable, and real-time control of the air-fuel equation. mapecu3

The MAPECU3 acts as a secondary injector driver. It can control up to 16 injectors (8 primary, 8 secondary). This is particularly useful for high-horsepower builds where the factory injectors are maxed out. You can add a secondary set of injectors (or replace the primaries with massive units) and let the MAPECU3 handle the fueling, while the factory ECU simply believes it is still running the stock setup.
