AEM Infinity PNP Harness - 01-05 Porsche 996 Turbo M/T

Vendor: AEM


Full Drive-by-Wire and VarioCam Control
The Infinity ECU for the Porsche 996 provides two Drive-by-Wire profiles and complete control of the engines’ VarioCam variable valve timing system for optimizing mid-range torque. The factory Sport button is used to change DBW throttle curves. This adapter will not interface with the C4 model.

Full Engine Support for Mass Airflow Sensor and More
AEM’s Porsche 996 Infinity ECU supports the stock mass airflow (MAF) sensor and does not require the addition of a MAP sensor for operation. The factory boost solenoid for the 996 Turbo are also supported, as are the factory electronic bypass valves.

The Infinity ECU also provides full support for:

  • Stock charge pressure sensor
  • Engine compartment temp sensor
  • Engine blower fan
  • Stock fuel pumps
  • Dual stock UEGO sensors

Racing Enabled Functions via Configurable Cruise Control Buttons 
On the Porsche 996, the Infinity programmable ECU delivers the ability to enable racing functions through the Cruise Control buttons. Using InfinityTuner software, users can now select from 8 modes for boost control maps, fuel maps, timing maps, Lambda target and select maps on the fly using the factory cruise UP (+) and DOWN (-) buttons. AEM incorporated the Infinity’s map switching capability into the factory steering wheel 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 and traction control slip target can also be programmed.

Traction Control
The Porsche 996 Turbo come with wheel speed/ABS sensors from the factory, and the Infinity is able to use them for traction control via fuel cut, spark cut, spark retard or retracting DBW throttle response. 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 996 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.

  • 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
