After Nissan stopped development of the 300ZX, they left those in the US high and dry without a fun sports car offering. After about 8 years of no great options from Nissan, enthusiasts rejoiced with the introduction of the Nissan 350Z. With its 3.5L dual overhead cam engine and RWD layout it quickly became a popular choice for a sports car. Today the prices for 350Zs have dropped significantly allowing almost everyone the chance to own a fun RWD sports car from Nissan again. With the popularity of the 350Z lots of manufacturers developed aftermarket options for the car. Lot of those options require a capable engine management system to make sure the engine is still running safely. Enter the AEM Infinity Series 7 EMS. When you pair an AEM Infinity 708 (30-7110) or AEM Infinity 710 (30-7107) EMS to the AEM Infinity Series 7 Plug and Play Adapter harness for the 2003-2006 Nissan 350Z and Infiniti G35 you’ll have a plug and play solution for a motorsports level engine management system utilizing the stock ECU plug. This adapter harness will only work for manual transmission vehicles.
AEM’s sealed, weatherproof Plug & Play harness includes 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. It includes a Wideband O2 connector for use with a Bosch 4.2 LSU UEGO air/fuel ratio sensor (30-2001) and for an easy install we recommended that you purchase a Wideband Extension Cable (30-3600).
The AEM Infinity EMS and the Plug and Play adapter harness allows full control of 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.
Nissan 350Z/Infiniti G35 Plug & Play Harness with Expansion Port
Once you have determined which Infinity ECU will best support your Nissan 350Z/G35, you will need to purchase the Nissan 350Z/G35 Plug & Play adapter harness (PN 30-3520). AEM’s engineers have designed the Infinity ECU and harness to fit in the Nissan 350Z/G35 factory ECU location to maintain overall weather resistance of the electronics and deliver a clean look in the engine compartment.
PLEASE NOTE: Infiniti G35 MT owners will require a custom bracket that will allow the Infinity to fit in the factory ECU location. AEM manufactures this bracket and the part number is 30-3596. This bracket is not required for the Infinity to fit in the 350Z factory ECU location.
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.
