Info

THE SERIES 5 PLATFORM

The Infinity 506 and Infinity 508 ECUs are affordable state-of-the-art engine control units designed for four- and six-cylinder racing engines (typically Infinity 506), and racing engines with up to 8 cylinders that are using high-impedance injectors (Infinity 508). A Powersports version is available for Polaris RZR 900, 1000 and XP Turbo applications (PN 30-7112). The Series 5 features a smaller footprint than the Infinity Series 7 at 5.855” x 5.55” x 1.8”, and has a single, weatherproof 80-pin connector.

Infinity 506

The Infinity 506 is designed for racing engines with up to 6 cylinders.

Infinity 508

The Infinity 508 is designed for high-performance V8 crate engines and race engines using high impedance injectors with up to 8 cylinders. A special Powersports version is available for Polaris RZR 900, 1000 and XP Turbo applications using Plug & Play Adapter Wiring Harnesses specific to each application.

SELECTING THE RIGHT INFINITY ECU

Infinity ECU modules are designed for maximum flexibility across many types of applications. ECU modules and harnesses are sold separately for both Supported and Plug & Play applications. Choose the ideal Infinity ECU based on your application’s ignition and fuel injector output requirements using the Infinity Specifications Chart, and then choose between our available Plug & Play or Universal harnesses to create the Infinity solution that suits your specific needs.

SUPPORTED vs. PLUG & PLAY APPLICATIONS

The Infinity ECU delivers comparable tuning functionality regardless of application type. It is available for a wide variety of applications in two distinct forms:

Supported Applications

  • Infinity Supported applications refer to an engine family or cam/crank pattern for which the Infinity ECU has been tested and validated to run. However, certain ancillary vehicle systems (such as factory instrument clusters, automatic transmissions, and certain drive by wire throttles), may not be supported.
  • The setup Wizard included with the InfinityTuner user interface software dramatically simplifies initial tuning configuration to help ensure successful initial startup for Supported applications.
  • Wiring is required for Supported applications. AEM offers Universal wiring harnesses in several iterations and detailed application-specific wiring instructions/schematics.

Plug & Play Applications

Infinity Plug & Play applications are available for select vehicles. Plug & Play applications support a vehicle’s engine and most other ancillary vehicle systems, and include application-specific start up calibrations. The Infinity Plug & Play harness (sold separately) connects directly into the vehicle’s factory ECU harness and requires no additional wiring.

200MHz Processor and Real-Time Operating System

Late-model vehicle ECU’s all run on faster processors. The Infinity ECU is built around a latest-generation 32-bit floating point 200MHz automotive processor and Real-Time Operating System (RTOS), which is capable of processing 400 MIPS (millions of instructions per second). By comparison, common competitive systems typically use 20MHz to 50MHz processors. To our knowledge, the Infinity ECU currently has the fastest processing speed of any aftermarket Motorsports ECU available. This allows the Infinity to do more, faster, in a more stable programming environment.

  • The Infinity’s 200MHz processor and RTOS makes the Infinity more responsive, for a better driving experience
  • The Infinity’s 200MHz processor and RTOS allows for more accurate ignition timing, which enables an engine to create more power
  • The Infinity’s faster processor allows it to perform more computational features with no sacrifice in processing performance
  • The Infinity’s RTOS ensures strategic processing with optimized load balancing. This means that tuning one feature will not affect the performance of another feature

All Infinity ECU’s 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.

**This model: AEM 30-7112 fits Polaris 2011-2014 RZR 900 & 2014-2015 RZR 1000 and 2016 RZR XP Turbo

Notes

The Infinity Series 5 include all of the advanced features found in the Infinity Series 7 including the latest generation 200 MHz automotive processor that can process 400 MIPS. Airflow model-based (VE) tuning eliminates lookup of many correction tables needed in previous generation ECUs. Flex-fuel and multi-fuel capability, on-board wideband air/fuel control, map switching and knock control are included. Engine protection strategies include coolant temp, oil temp, AFR vs. MAP, intake air temp, knock and fuel pressure. Programmable drive-by-wire, variable cam timing, boost control, nitrous control, and 2-wheel speed-based traction control are included. Data logging up to 64 GB via a removable USB drive is standard with logging rates up to 1 KHz per channel. The Infinity Series 5 is able to communicate with 3rd party dashes and loggers and is AEMnet enabled. All maps can be password protected.

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. (SHOW IMAGE OF WIZARD). 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, wheel speed-based 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).

MULTI-FUEL CAPABLE

The Infinity has the ability to run two separate fuel types simultaneously through staged fuel injection

DRIVE-BY WIRE CAPABILITY

The Infinity Series 5 ECU can control one drive by wire throttle body 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.

IDLE CONTROL

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.

NITROUS CONTROL

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.

MAP SWITCHING

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

ENGINE PROTECTION

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

A Bosch wideband controller is built into the Infinity ECU. 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.
