Infinity-708 Stand-Alone Programmable Engine Management System

The AEM Infinity-708 Stand-Alone Programmable EMS is an engine control solution for manual transmission 2003-2006 Nissan 350Z and Infiniti G35 models. The Infinity-708 utilizes an airflow model-based (volumetric efficiency) system for efficient and real-time engine management, reducing the need for extensive lookup and trim tables common in older ECUs. It boasts an ECU Setup Wizard for simplified calibration and features a powerful input simulator for validating tuning changes before engine startup. The system supports tuning and logging via IP-67 rated weatherproof connection cables (PC cable sold separately). Advanced tuning functions include no-lift shift, 4-wheel speed traction control, 3-step launch control, and drive-by-wire capabilities. The system can leverage factory wideband sensors on 2004.5-up VQ35DE and VQ35DE-RU models and integrates map switching into the factory cruise control buttons for on-the-fly adjustments to boost, fuel, and timing maps. For Infiniti G35 MT owners, a custom bracket (PN 30-3596) is required to fit the Infinity in the factory ECU location; this bracket is not necessary for the 350Z. The sealed, weatherproof Plug & Play harness is sold separately and includes an expansion port for additional aftermarket sensors.
