The Infinity ECU delivers state-of-the-art programmable EFI control capabilities typically found only at upper echelons of Motorsports. Through the Infinity ECU, AEM makes this technology affordable for both professional race teams and amateur racers.

Each Infinity ECU includes ignition coil outputs and injector drivers equivalent to its name. The Infinity's airflow-based tuning models simplify startup and speed up the tuning process by eliminating many of the lookup and trim tables (Correction Tables) necessary in previous generation ECUs. For a limited time, all Infinity systems come fully enabled without the need for feature add-on purchases. Combined with AEM's industry-leading after-purchase support system, including free technical support, the Infinity is the ultimate engine control solution for both professional race teams and weekend track cars.

Infinity's airflow model-based systems greatly reduce the amount of time it takes to set up and tune an engine by eliminating many of the lookup and trim tables (correction tables) necessary in previous generation ECUs. The Infinity's airflow based, or volumetric efficiency (VE) based models calculate an engine's requirements in real time based on an advanced algorithm that has various modes for calculating air flow. Once the user inputs an engine's basic parameters (displacement, cylinders, ignition type, and firing order) and methods of calculation for airflow and ignition they can begin setting the engine's VE table in the software.
