AIRFLOW MODEL BASED CALCULATIONS
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.
InfinityTuner USER INTERFACE SOFTWARE
InfinityTuner is optimized for speed and performance. The software has the power to control a multitude of features found in today’s modern racecars and features an advanced tuning Wizard to reduce set up time. An ECU Setup Wizard takes complex calibration setup work and simplifies it through a smart interface that features tabs for quick set up of vital engine functions. Each tab includes a description of the function.
InfinityTuner software is highly flexible. It allows you to choose from multiple strategies for boost control, idle control, traction control, charge air temp blend, launch control and more.
All controls in the Infinity ECU are synched to logged data which allows users to edit calibration data during log playback to minimize tuning time. AEMdata, AEM’s advanced data logging analysis software is also included for reviewing data logs.
ULTRA-HIGH RESOLUTION FUEL CONTROL
The Infinity ECU calculates injector pulsewidth in units of 1/10th of a microsecond (0.0000001 seconds). Individual cylinder fuel trim is included and user-adjustable.
ACCURATE IGNITION TIMING UNDER ANY CONDITION
InfinityTuner software features a 3D ignition trim map (coolant and air temp based), and its back-end timing code is tested to 100,000 RPM. Individual cylinder ignition trim is included.
FLEX FUEL COMPENSATION
Flex-fuel compatibility is included, and the Infinity is able to make automatic adjustments for ethanol content in the fuel with the addition of an ethanol content sensor (sold separately).
The Infinity has the ability to run two separate fuel types simultaneously through staged fuel injection
DRIVE BY WIRE CAPABILITY
The Infinity Series 7 ECU can control two drive by wire throttle bodies and includes auto calibration for DBW sensors. It includes idle control, an optional drive by wire rev limiter (for use as a launch limiter, holding limiter or in conjunction with other rev limiters) and necessary failsafes based on redundant sensor inputs.
The Infinity ECU uses a coolant temp based idle control model. It includes an RPM vs. Engine Speed Rate idle decel feature that provides accurate control of the IAC and allows for adjustment of engine braking. The Infinity’s idle TPS offset provides smoother low idle operation when necessary, like driving in the pits or return lane following a pass.
MULTIPLE BOOST CONTROL STRATEGIES
Choose from time, gear, vehicle speed, switch-based or other boost control strategies. The Infinity’s boost control includes two 2D base duty tables and two 2D boost target tables. The second tables can be used as a trim, and users can choose from multiple strategies including IAT, MAP, Baro (kpa), throttle %, flex fuel content, boost target and more. Please visit our Forum for an in-depth review of the Infinity’s boost control capabilities.
The Infinity’s software allows you to run a single-stage wet or dry nitrous set up (four-stage available soon). This feature includes nitrous timing delay to account for nitrous bleed out and can be set up for water/methanol injection tuning. Four stage nitrous will be upgraded for free for existing Infinity users when it becomes available.
VARIABLE VALVE CAM CONTROL
Set base duty, limit and VVC cam target for up to four cams through the InfinityTuner Wizard. Users are able to achieve a VVC cam target by setting Cam 1 base timing and base duty cycle % in a 2D table, and the software features a 1D base duty % table that controls the base duty cycle for the VVC output, which is tunable based on the VVC target.
The Infinity includes up to four separate ignition maps, four separate Lambda maps and two separate VE maps with independent values. Using AEM’s 12 Position Trim Pot, this powerful feature delivers many valuable tuning options including:
- Multiple maps for multiple track conditions (practice map, rain map, qualifying map, FTW map)
- Change boost target
- Change Lambda target
- Change ignition target
- Tie boost, Lambda and ignition targets together and change them all
- Ideal for test mapping during tuning
- Change boost base duty
- Control PWM switches (like water/methanol injection)
- Choose between 2 VE tables for VVC or when restrictors are in place
- Blend between flex fuel ignition maps
- Blend by cam position and gear
Multiple engine protection strategies are incorporated into the Infinity ECU. Available strategies include:
- MAP (create limp mode using Assumed Pressure Ratio table to compensate for pressure if sensor fails)
- Overboost (boost fuel cut until boost/throttle decreases)
- Fuel pressure (injector flow compensated for variations in pressure, sensor required)
- Oil pressure (trigger light or limit RPM if pressure drops below set value, sensor required)
- RPM (rev limiter)
- Coolant temperature, Temp vs. RPM (fuel and ignition cut, sensor required)
- Knock control with feedback
- Lean protection (fuel and ignition cut)
REAL-TIME ADVANCED DIAGNOSTICS
The Infinity’s diagnostics software can be configured to constantly monitor signal and current quality to alert the user of a potential issue before it creates the potential for engine damage.
INTERNAL WIDEBAND CONTROLLER
Dual Bosch wideband controllers are built into Infinity-8/10 ECUs. This provides highly accurate closed-loop AFR targeting and enables the sensor diagnostics in the ECU to determine the operational condition of the sensor.
LIGHTNING-FAST DATA LOGGING
Infinity’s logging feature supports 2 different file systems. A custom file system option will support 100 channels at up to 1 KHz using a high-performance USB flash drive (sold separately). A standard FAT file system will support 10 channels at up to 1KHz, 20 channels at up to 500Hz or 100 channels at up to 200Hz. The Infinity includes a 4GB USB memory stick and the user can replace this with up to 64GB. Additionally, the user can also log directly to the PC at up to 500Hz when connected.
AEMdata DATA ANALYSIS SOFTWARE
AEMdataprovides an advanced interface for viewing the log files generated by the Infinity ECU.
DUAL KNOCK SENSING
Dual knock signal conditioning circuits allow for precise measurements of knock levels. The Infinity can utilize both Piezoelectric and Flat Response type knock sensors.
The Infinity ECU is constructed using automotive-rated components designed to withstand the harshest racing environments. Its enclosure and connectors are sealed to make it suitable for engine bay mounting. An advanced wear-leveling strategy for flash memory ensures a lifetime of reliable performance.
The Infinity ECU is able to transfer data via USB at up to 480 Mb/second. It features a fully-sealed IP67 communications connection system.

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.
