Begin by determining which Infinity ECU will best support the ancillary components in your manual transmission 2001-06 E46 M3 using the Infinity Specifications Chart. The manual transmission 2001-06 BMW E46 M3 Plug & Play includes several unique features that incorporate the BMW’s factory CAN bus system (listed below), and have unique part numbers (30-7105 for Infinity-10 and 30-7109 for Infinity-8).

Map Switching
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. Using InfinityTuner software, users can now select from 8 modes for boost control maps, fuel maps, timing maps, Lambda target maps and more and select maps on the fly using the factory cruise UP (+) and DOWN (-) buttons.

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.
