INFINITY 308

The Infinity 308 (PN 30-7113) features two different injector types and two different coil outputs that support three different types of fuel and ignition configurations.

For throttle-body-injected (TBI) and GM multi-port fuel-injected V8s, the Infinity 308 includes a single direct-drive ignition coil output to work with a distributor and a single-coil, and 2 peak & hold injector drivers that can drive up to four high-impedance injectors each. Other port injected and single-coil distributed V8 engines like the Ford Windsor can be controlled using the Infinity 308’s 8 high impedance injector drivers and single direct-drive coil output.

For the Chevy LS, the Infinity 308 has 8 high impedance injector drivers and 8 “smart” coil outputs to drive a coil-near-plug ignition system.

INFINITY 358

The Infinity 358 (PN 30-7114) is designed to control 2V and 4V Ford Modular engines, late-model Dodge Hemi engines, and other late-model, individual direct-drive “dumb” coil V8 engines with port injection using 8 high impedance injectors.

Optional Accessories

The Series 3 Infinity ECUs do not include an on-board Lambda sensor controller for wideband air/fuel ratio. If you do not have a wideband air/fuel controller we recommend our X-Series Wideband Controllers (Inline or Gauge).

The Infinity Series 3 ECUs include a basic engine history feature. If you require robust data logging capability we recommend our AQ-1 Data Logger, which can be connected to the Infinity through a simple AEMnet CAN bus connection.

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

  • Fuel Injection control via airflow model-based (VE) tuning
  • Full ignition control
  • Closed-loop AFR feedback
  • ECU Set Up Wizard simplifies startup
  • Flex-fuel compatible
  • Multiple boost control strategies
  • Nitrous control
  • Map switching
  • Dual knock sensing circuits
  • Engine history
  • Outputs to 3rd party dashes and data loggers
  • Integrated engine protection strategies
  • Sealed enclosure and IP67 rated comms ports

Notes

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).

MULTI-FUEL CAPABLE

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

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.

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.

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.

CLOSED-LOOP AFR FEEDBACK CONTROL

Infinity Series 3 users have the ability to add up to two external wideband air/fuel ratio (AFR) sensor controllers via analog inputs or through AEMnet CANbus using AEM's X-Series Wideband AFR Controllers for closed-loop wideband AFR feedback control.

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. 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.

COMMUNICATIONS

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.
