AEM has expanded its Porsche 997.1 Infinity ECU to include the 2005-’08 Carrera, Targa and GT3 in addition to the 2007-’09 Turbo and GT2 models. The Infinity ECU part number is PN 30-7109, and the new Infinity Plug & Play Adapter Harness for 997 Porsches is PN 30-3905. When combined with AEM’s Plug & Play Adapter Harness, the Infinity completely replaces the factory Porsche 997.1 ECU and does not require any additional accessories, sensors or modules for proper operation. Installation can be completed in about an hour when using all of the factory sensors.
Full Drive-by-Wire and VarioCam Plus Control
The Infinity ECU for Porsche 997.1 models provides two Drive-by-Wire profiles and complete control of the engines’ VarioCam Plus variable valve timing system for optimizing mid-range torque. The factory Sport button can be used to change DBW throttle curves.
Full Engine Support for Mass Airflow Sensors, Wastegate-less Turbos and More
AEM’s Porsche 997.1 Infinity ECU supports stock mass airflow (MAF) sensors and does not require the addition of a MAP sensor for operation. The factory wastegate-less variable turbine geometry turbos used in the 997 Turbo and GT2 are also supported, as are the factory electronic bypass valves.
The Infinity ECU also provides full support for:
Stock charge pressure sensor (Turbo models)
Engine compartment temp sensor
Engine blower fan
Electronic water pump (Turbo models)
Dual stock fuel pumps
Dual stock EGT sensors (Turbo models)
Dual stock wideband air/fuel sensors
Plug & Play Harness with Expansion Port
AEM’s sealed, weatherproof Plug & Play harness (PN 30-3905, sold separately) includes an AEMnet port for communication with other AEMnet enabled devices and CAN integration of the factory inputs for brake switch, clutch switches, cruise buttons, wheel speed sensors, sport button, coolant fans and A/C. The factory dash remains functional on all Porsche 997.1 models (coolant temp, oil temp, oil pressure, tachometer, dash lights/notifications, boost pressure readout on Turbo models, etc.).
An expansion port with a Deutsch DTM 12P connector is included in the Plug & Play Adapter Harness for adding common aftermarket sensors including fuel pressure, air inlet temperature, MAP, boost control solenoid (on Turbo models) and ethanol content. The expansion port also includes a sensor ground, 5v reference, power from relay and high side output for activating a solenoid, and switched inputs for boost target, no-lift shift, etc.
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 Infinity Tuner 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.
Traction Control
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.
Enhanced Security
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.

The Infinity ECU makes state-of-the-art ECU technology affordable for both professional teams and amateur racers. Built around a latest-generation 32 bit floating point 200MHz automotive processor and Real Time Operating System (RTOS), the Infinity is capable of processing 400 MIPS (millions of instructions per second). To our knowledge, the Infinity ECU currently has the fastest processing speed of any aftermarket Motorsports ECU available. This processing speed combined with a RTOS provides more accurate ignition timing for increased power, more responsiveness to truly custom tailor the driving experience to the driver, allows the Infinity to perform more computational features without a sacrifice in processing performance, and enables tuning of features and sub strategies without affecting other features and sub strategies. It allows you to do more, faster, in a more stable programming environment.
