The Infinity ECU also provides full support for:
Racing Enabled Functions via Configurable Cruise Control Buttons
The Infinity programmable ECU delivers the ability to enable racing functions through the Cruise Control buttons on all Porsche 997.1 models. Using InfinityTuner software, users can now select from 8 modes for fuel maps, timing maps, Lambda target and more, and select maps on the fly using the factory cruise UP (+) and DOWN (-) buttons, eliminating the need to wire in and mount an ancillary position switch.
Users can configure the CRUISE CANCEL as a temporary three step limiter switch through the InfinityTuner software (vehicle speed or time after launch dependent), and can set rev limits at specific rpm by points or set a flat limiter and use it as an RPM hold for launches.
Launch anti lag, traction control slip target and rolling launch can also be programmed.
The Infinity is able to use the factory wheel speed/ABS sensors for traction control via fuel cut, spark cut, spark retard or retracting DBW throttle response on all 997 models. This eliminates the need to install additional sensors for traction control.
The CRUISE SET/HOLD can be configured as a traction control enable or disable button through the InfinityTuner software. Users can define a specific slip target for traction control in the software and turn it on or off using this button, or set two slip targets and use it for a mild and aggressive traction control strategy.
User Definable DBW Throttle Response
Using the Sport button, users can define throttle curves in the InfinityTuner DBW software and take full control of throttle response. This allows users to change throttle response rate on the fly and is ideal for setting rain mode throttle curves.
Fits In Factory ECU Location
AEM’s engineers have designed the Infinity ECU and harness to fit in the factory ECU location under the shelf to maintain overall weather resistance of the electronics.
Users can configure a number of analog, digital or CAN inputs to enable starting when using the Porsche 997.1 Infinity ECU and Plug & Play Harness. The supplied base calibration is configured to allow factory like starting with the clutch switch, or by pressing the cruise control enable button to effectively bypass the clutch switch. For added security, users can install a hidden switch to enable starting, and can fully disable the 2D Start Enable table and password protect it, preventing starting until the table is unlocked and re-enabled through password input.
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.
Infinity ECU Features for Porsche 997.1 Turbo and N/A Models:
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).
The Infinity has the ability to run two separate fuel types simultaneously through staged fuel injection
DRIVE BY WIRE CAPABILITY
The Infinity Series 7 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.
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.
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.
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 engine protection strategies are incorporated into the Infinity ECU. Available strategies include:
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.
INTERNAL WIDEBAND CONTROLLER
Dual Bosch wideband controllers are built into Infinity Series 7 ECUs. This provides highly accurate closed-loop AFR targeting and enables the sensor diagnostics in the ECU to determine the operational condition of the sensor.
LIGHTNING-FAST DATA LOGGING
