AEM has released the Infinity Programmable Engine Management System for race vehicles.
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. Supported timing patterns, technical specs and features for each Infinity EMS are on www.aemelectronics.com/infinity/specs.
UNIVERSAL AND PLUG & PLAY HARNESSES
Visit www.aemelectronics.com for a list of Plug and Play applications and supported timing patterns for Universal applications.
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).
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.
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.
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).
