TECHNOLOGY 

The Infinity’s primary automotive MCU is a 200 MHz, 32 bit processor with a math co-processor. It is able to process 400 MIPS. It includes up to 12 peak and hold injector drivers and up to 12 ignition outputs. Infinity’s USB technology downloads up to 480 Mb/second. The enclosure and connectors are sealed and suitable for engine bay mounting. It features a fully-sealed IP67 rated connection system.  

AVAILABLE INFINITY ENGINE CONTROL SYSTEMS

The first release of AEM’s next-generation programmable engine management system includes the Infinity-6, Infinity-8, Infinity-10 and Infinity-12. Each system will have peak and hold injector drivers and ignition outputs equivalent to its name.  CLICK HERE for Infinity Specifications Chart 

UNIVERSAL AND PLUG & PLAY HARNESSES

Plug & Play applications include a vehicle specific jumper harness(sold separately) and an application specific base map.  CLICK HERE for plug & play applications that include a vehicle specific adapter harness

InfinityTuner USER INTERFACE SOFTWARE

InfinityTuner features custom layouts, an ECU Setup Wizard, and data logging playback mode where all controls are synched to the logged data. This allows you to edit calibration data exactly where you need to and minimize your tuning time. AEMdata data logging analysis software is also included.

AIRFLOW MODEL BASED CALCULATIONS

Infinity system base models are airflow based and feature various modes for calculating air flow. This eliminates many of the lookup and trim tables (Correction Tables) which are necessary in previous generation ECUs.

FUEL CONTROL & IGNITION TIMING

The Infinity EMS calculates injector pulsewidth in units of 1/10th of a microsecond (0.0000001 second) and has NO practical crank tooth resolution limit. The Infinity’s back-end timing code is tested to 100,000 RPM.

DATA LOGGING

Log 10 channels at up to 1KHz, 20 channels at up to 500Hz or 100 channels at up to 200Hz standard. Log 100 channels at up to 1 KHz using a high performance USB flash drive (not included). An included 4GB USB memory stick can be replaced with one up to 64GB. Users can also log direct to the PC at up to 500Hz.

DUAL INTERNAL WIDEBAND CONTROLLER

A built-in 2-channel Bosch wideband controller with automatic closed-loop heater control optimizes sensor performance and reliability. Full diagnostics software ensures reliable operation.

FLEX FUEL COMPENSATION

The Infinity’s core control model is designed for flex fuel compatibility. It makes automatic adjustments for ethanol content and applies them to fuel flow, ignition timing and boost target (ethanol content sensor is sold separately).

MULTI-FUEL CAPABLE

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

DUAL KNOCK SENSING

Dual knock signal conditioning circuits allow for precise measurements of knock levels. 

INTERNAL SIMULATOR

A powerful input simulator feature allows the user to simulate operating conditions. This allows users to validate tuning changes before running the engine.

REAL-TIME ADVANCED DIAGNOSTICS

The Infinity’s diagnostics software constantly monitors signal and current quality to alert the user of an issue before it creates the potential for engine damage.

INTEGRATED ENGINE PROTECTION STRATEGIES

Available strategies are based on boost fuel cut, fuel pressure (injector flow compensated for variations in pressure, sensor required), oil pressure, RPM (rev limiter), coolant temperature, knock control with feedback and lean protection.

NETWORK INTERFACES

Infinity is AEMnet enabled and will communicate with another AEMnet-equipped device and output to 3rd party dash/logger devices (not all 3rd party dash/logger devices may be supported).

INFINITY EMS ADVANCED TUNING PACKAGE

Certain Advanced Tuning functions, hardware outputs and sensor inputs (see “Advanced Tuning Package” below) for the Infinity Programmable EMS are sold separately. Please contact an AEM Authorized Infinity Retailer or call AEM Performance Electronics at (310) 484-2322 for more info.

I have been following the I-10 on a couple of forums & it seems like one of the next big things. I know that it's available for the Supra currently, but this is no info on when & what other vehicles it will be available for.

Okay, I just have to ask - what's this "airflow model based calculations" stuff mean? No VE table? Because that doesn't seem right.

Kenku,
The Infinity specs look a lot like the latest generation of GM ECUs. That being the case the "airflow model based calculations" are just more accurate interpretations of the VE table using real time calculations to establish the VE for a given condition based on a large number of coefficients.
How that is presented to the tuner in the software is the key to understanding and utilizing the system as a whole.

A quick Google search for "Virtial VE Tutorial" and "EFILive E38 E67 GM ECU" will shed some light on how this technique is tackled with OEM ECUs and aftermarket tuners.
