AEM Infinity 708 Stand-Alone Programmable Engine Management System for Nissan 350Z/G35

AEM has released its Infinity Plug & Play programmable ECU for the 2003-’06 Nissan 350Z/Infiniti G35 equipped with a manual transmission (Infinity-8 PN 30-7110 and Infinity-10 PN 30-7107). The Infinity ECU for the 350Z/G35 includes an application-specific start-up calibration and connects via a Plug & Play harness that is sold separately (PN 30-3520). It is designed to fit in the factory location (requires AEM bracket on G35 models, PN 30-5936).

Complete Stand Alone Engine Control
The Infinity ECU combines with the Plug & Play harness to replace the 350Z/G35’s factory ECU. It controls all of the engine functions including up to four cam variable cam control (VQ35DE-RU) and the Drive by Wire (DBW) system. An AEM MAP sensor (sold separately) is required for proper operation of the Infinity ECU on this application.

Plug & Play Harness with Expansion Port
AEM’s sealed, weatherproof Plug & Play harness (sold separately) includes dual Lambda connectors, an AEMnet connector for communication with other AEMnet enabled devices and an auxiliary connector with a High Performance DTM-Style 12P connector for adding common aftermarket sensors including fuel pressure, air inlet temperature, MAP, oil temperature and ethanol content sensor. The expansion port also includes a sensor ground, 5v reference, 12v power from relay and high side output for activating a relay solenoid, a low side output for boost control and analog inputs for mode switch and no-lift shift.

Uses Factory Wideband Sensors
On 2004.5-up VQ35DE and VQ35DE-RU 350Z/G35 models, the Infinity is able to use the factory wideband air/fuel ratio sensors, eliminating the need for additional sensors and cables. A fuse and relay for battery positive is integrated into the adapter harness for models that require ancillary wideband sensors.

Map Switching via Cruise Control Buttons
For 350Z/G35s equipped with cruise control, AEM incorporated the Infinity’s map switching capability into the factory cruise control buttons on the steering wheel, eliminating the need to wire in and mount an ancillary position switch. Using InfinityTuner software, users can now select from 8 modes for boost control maps, fuel maps, timing maps and Lambda target, and select maps on the fly using the factory cruise UP (ACCEL/RES) and DOWN (COAST/SET) toggle button.

To ensure that drivers know which mode they are in when not connected to the Infinity ECU, when the vehicle is keyed ON the tachometer moves to a specific RPM point to indicate which map the Infinity is using (for example 3k RPM indicates Mode 3, 4k RPM indicates mode 4, etc.). When the driver changes maps while driving, the tachometer will momentarily change from revs to the RPM point that indicates the switched mode and then resume normal tachometer operation. Actual engine RPM will not be affected during this brief period.

Three-Step Rev Limiter
Users can configure the 350Z/G35’s CRUISE ON/OFF as a temporary three step limiter switch through the InfinityTuner software (vehicle speed or time after launch dependent), and can set rev limits at specific rpm by points or set a flat limiter and use it as an RPM hold for launches.

Traction Control
The Infinity is able to use the 350Z/G35’s factory wheel speed/ABS sensors for traction control via fuel cut, spark cut, spark retard or retracting DBW throttle response in 350Z/G35s equipped with factory cruise control, eliminating the need to install additional sensors for traction control (in applications without cruise control, these functions can be incorporated through the 12 pin auxiliary port on the plug & play harness with a trim position switch).
