AEM Infinity 708 Stand-Alone Programmable Engine Management System for BMW E46 M3, Porsche 996 Turbo & Porsche 997.1

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 High Performance DTM-Style 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 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.
