AEM Infinity 8 708 Stand Alone EMS for Nissan 350Z G35 2003-2006 Manual without harness
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.
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).
The cruise control CANCEL button can be configured as a traction control enable or disable button through the InfinityTuner software. Users can define a specific slip target for traction control in the software and turn it on or off using this button, or set two slip targets and use it for a mild and aggressive traction control strategy.
User Definable DBW Throttle Response
Users can define throttle curves in the InfinityTuner DBW software and take full control of throttle response. Using an ancillary switch via the 12 pin auxiliary port, drivers can change throttle response rate on the fly via two DBW settings (ideal for setting rain mode throttle curves).
Communicates with Factory CAN bus
The Infinity ECU communicates with the 350Z/G35’s factory CAN bus system and retains full functionality of the tachometer, speedometer, coolant temp gauge, fuel economy meter, MIL light, coolant fan control and vehicle speed sensors. On 350Z/G35s using Nissan’s Vehicle Dynamic Control (VDC), the Infinity is able to log steering angle and brake pressure.
The Infinity EMS delivers high-end engine control for the racing masses at a fraction of the cost. Built around a latest-generation 200MHz automotive processor, the Infinity is capable of processing 400 MIPS (millions of instructions per second). 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.
The Infinity’s airflow-based tuning models simplify start up and speed up the tuning process by eliminating many of the lookup and trim tables (Correction Tables) necessary in previous generation ECUs.
