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.

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 second). 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-8/10 ECU can control one drive by wire throttle bodies 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. Traction control via drive by wire will be added in the future at no additional cost for existing Infinity ECU owners.

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 Forumfor 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
