The Infinity ECU delivers state-of-the-art electronic fuel injection (EFI) control technology which provides durability, flexibility and capabilities typically found only at upper echelons of Motorsports. We have now made this technology affordable for both professional race teams and amateur racers. Built around a latest-generation 200MHz automotive processor, the Infinity ECU is capable of processing 400 MIPS (millions of instructions per second) and is perhaps the fastest ECU available today.

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.

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.

ULTRA-HIGH RESOLUTION FUEL CONTROL

The Infinity ECU calculates injector pulsewidth in units of 1/10th of a microsecond (0.0000001 second). Individual cylinder fuel trim is included and user adjustable vs. engine RPM.

ACCURATE IGNITION TIMING UNDER ANY CONDITION

InfinityTuner software features several 3D ignition trim maps (coolant and air temp based), and its back-end timing code is tested to 100,000 RPM. Individual cylinder ignition trim is included and is user adjustable vs. engine RPM.

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 ECU can control one or two drive by wire throttle bodies and includes auto calibration for DBW sensors

IDLE CONTROL

The Infinity ECU uses a coolant temp based idle control model

MULTIPLE BOOST CONTROL STRATEGIES

Choose from time, gear, vehicle speed, switch based or other boost control strategies

NITROUS CONTROL

The Infinity's software allows you to run a single-stage wet or dry nitrous set up (four-stage available soon)

VARIABLE VALVE CONTROL

Set base duty, limit and VVC cam target for up to four cams through the InfinityTuner Wizard

MAP SWITCHING

The Infinity includes up to four separate ignition maps, four separate Lambda target 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:

INTEGRATED ENGINE PROTECTION STRATEGIES

Multiple engine protection strategies are incorporated into the Infinity ECU

REAL-TIME 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.

DUAL INTERNAL WIDEBAND CONTROLLER

A 2-channel Bosch wideband controller is built into the Infinity ECU for twin turbo or individual bank exhaust gas measurement. On board control of the sensors ensures reliable sensor operation and intelligent control of closed-loop feedback.

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/channel using an included high performance USB flash drive

AEMdata DATA ANALYSIS SOFTWARE

AEMdata provides 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.

RELIABILITY

The Infinity ECU is constructed using automotive-rated components designed to withstand the harshest racing environments

COMMUNICATIONS

The Infinity ECU is able to transfer data via industry-leading High Speed USB at up to 480 Mb/second. It features a fully-sealed IP67 communications connection system.

NETWORK INTERFACES

Infinity is AEMnet enabled and will soon communicate with all AEMnet-equipped devices. It is able to output to many 3rd party dash/logger devices (not all 3rd party dash/logger devices may be supported). Call AEM technical support at (310) 484-2322 for more information.

INTERNAL SIMULATOR

A powerful input simulator feature is included that allows the user to simulate input channels to the Infinity EMS. By simulating operating conditions users can validate tuning changes before running the engine.

MANUFACTURING TECHNOLOGY

Infinity uses the latest printed circuit board (PCB) manufacturing processes for Ball Grid Array (BGA) and Quad Flat No-Lead (QFN) components. Its PCB size is roughly 5.5" x 5.5".
