Aem Infinity 8 + Pnp Harness For 2001-2006 Bmw E46 M3 Manual Transmission on 2040-parts.com

AEM Infinity PNP 01-06 BMW E46 Manual Transmission - Please note this includes PNP harness PN 30-3510 which is normally sold separately.

The Infinity ECU for the 2001-06 BMW E46 M3 (Infinity-8 PN 30-7109) includes an application-specific start-up calibration and connects to the E46 M3 via a Plug & Play harness that is designed to fit in the factory location. Begin by determining which Infinity ECU will best support the ancillary components in your manual transmission E46 M3 using the Infinity Specifications Chart in the "Specs" tab. The manual transmission 2001-06 BMW E46 M3 Plug & Play includes several unique features that incorporate the BMW’s factory CAN bus system (see "Features" tab).

A Complete Stand Alone ECU for the E46 M3 or S54 Swap
The Infinity ECU combines with the Plug & Play harness to replace the E46 M3’s factory ECU. It controls all of the engine functions including the VANOS variable cam control system and Drive by Wire (DBW) system.

Plug & Play Harness with Expansion Port
AEM’s sealed, weatherproof Plug & Play harness (sold separately) includes dual Lambda connectors, an AEMnet connector for communication with other AEMnet enabled devices and an auxiliary connector with a Deutsch DTM 12P connector for adding common aftermarket sensors including fuel pressure, air inlet temperature, MAP, boost control solenoid 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 auxiliary radiator fan, boost target and no-lift shift.

E46 M3 Plug & Play Harness with Expansion Port
Once you have determined which Infinity ECU will best support your E46 M3, you will need to purchase the E46 M3 Plug & Play adapter harness (PN 30-3510). AEM’s engineers have designed the Infinity ECU and harness to fit in the E46 M3’s factory ECU location to maintain overall weather resistance of the electronics and deliver a clean look in the engine compartment.

Below are several features that the Infinity is able to utilize via the E46 M3’s sophisticated CAN bus system. AEM’s engineers were able to incorporate several features directly into factory buttons on the steering wheel and console to eliminate the need for additional wiring. Please refer to the installation instructions for more information.

INFORMATION ON INFINITY ECUS USED ON 2005-06 BMW E46 M3’S EQUIPPED WITH FACTORY COMPETITION PACKAGE:
When the Infinity is used on 2005-06 model year E46 M3s the DSC lamp will remain illuminated when the key is in the “on” position. Certain CAN-bus features of the Infinity are not available via the steering wheel cruise control buttons, as these vehicles did not come with factory cruise control buttons (the features integrated through CAN-bus can be added using an ancillary trim position switch).

To ensure that drivers know which mode they are in when not connected to the Infinity ECU, when the vehicle is keyed ON the tachometer moves to a specific RPM point to indicate which map the Infinity is using (for example 3k RPM indicates Mode 3, 4k RPM indicates mode 4, etc.). When the driver changes maps while driving, the tachometer will temporarily change from revs to the RPM point that indicates the switched mode for one second and then resumes normal tachometer operation. Actual engine RPM will not be affected during this one second period.

Three-Step Rev Limiter
Users can configure the CRUISE ON/OFF (1/0) 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.

Definable Rev Limit on Tachometer
The E46 M3’s tachometer incorporates an LED ring around the outer perimeter to suggest rev limits, and the Infinity ECU uses these LEDs to indicate user defined active rev limits. For instance, if the Coolant Protect feature in InfinityTuner is set with a rev limit to 5k RPM when the engine is cold, the rev limit is indicated via the lights around the perimeter of the tachometer until defined coolant temps for normal operation are achieved. Whatever rev limits a user configures will always be displayed, with the lowest defined rev limit value taking precedence in the LEDs surrounding the tachometer. This feature applies to any protect features, the three step limiter, etc.

Traction Control
The E46 M3 comes with wheel speed/ABS sensors from the factory, and the Infinity is able to use them for traction control via fuel cut, spark cut or retracting DBW throttle response. This eliminates the need to install additional sensors for traction control.

The CRUISE SET/HOLD (speedometer icon) 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
Users can define throttle curves in the InfinityTuner DBW software and take full control of throttle response using the Sport button near the shifter. This allows users to change throttle response rate on the fly and is ideal for setting rain mode throttle curves.

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

• Airflow model based (VE) tuning
• ECU Set Up Wizard simplifies start up
• Flex fuel compatible
