OVERVIEW
The 30-3510 AEM Infinity Adapter Kit was designed for the 2001–2006 BMW E46 M3 with manual transmission. This is a true standalone system that eliminates the use of the factory BMW DME (ECU).
The use of this adapter makes the kit “plug and play” so no cutting or splicing wires is necessary. The base configuration files available for the Infinity EMS are starting points only and will need to be modified for every specific application. Included in these instructions are descriptions of important differences between using the factory BMW DME and using the AEM Infinity ECU.
The available AEM Infinity EMS part numbers for this adapter kit are:
30-7109 INFINITY-8
30-7105 INFINITY-10
NOTE: The Infinity-10 EMS has 2 extra ignition coil and injector outputs for a total of 10 each. These are sold separately from this adapter kit.
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.)

INFINITY ADAPTER HARNESS
Included with the BMW E46 M3 kit is an adapter harness. This is used to make the connection between the AEM Infinity EMS and the BMW wiring harness plug and play. This is depicted below with the 73-pin and 56-pin connectors and the BMW M3 header. There are also a few other integrated connectors within this harness described below.
The gray Deutsch 6P DTM “Lambda #1” and “Lambda #2” plugs are for connecting UEGO wideband
Bosch LSU4.2 sensors (AEM 30-2001). The UEGO extension harness (AEM 30-3600) mates the adapter harness to the sensor (1 required for each sensor used). Note: Even though the BMW S54 engine architecture is inline, the stock exhaust system pairs the cylinders (1,2,3 and 4,5,6) into 2 separate banks. For this case, 2 sensors are recommended. If a single turbocharger is used, 1 sensor is sufficient.
The gray Deutsch 4P DTM connector is used for “AEMNet”. AEMNet is an open architecture based on
CAN 2.0 which provides the ability for multiple enabled devices, such as dashboards, data loggers, etc., to easily communicate with one another through two twisted cables (CAN+/CAN-).
The black Delphi 2-pin “Flash Enable” connector is used for secondary hardware flashing. The included shunt connector jumps the 2 wires together. Once initially flashed, the EMS is normally upgraded in the software, not using this connector.

The gray Deutsch 12P DTM “Auxiliary” connector (shown below) is used to adapt many common ancillary inputs and outputs easily. Included in the kit are a
DTM 12P mating connector, 12 DTM terminals, and a DTM 12P wedgelock. If used, these components will need to be terminated by the installer or end user with 16
–
22awg wire (not included). Note: the pin numbering is molded into the connector, as shown.
Below is a description of each of the available input/output found in the BMW specific “Auxiliary” connector.

EXHAUST GAS TEMPERATURE SENSOR
The BMW M3 S54 engine uses an exhaust gas temperature sensor (EGT). This is a 0
–
5V resistive temperature device (RTD) that is input to the Infinity EMS. AEM has already done the work by calibrating and entering the EGT data (shown below) into the base session files. There is currently no fuel control, but this channel can be data logged for tuning purposes.

DRIVE-BY-WIRE THROTTLE CONTROL
The BMW M3 S54 engine uses 6 individual throttle bodies controlled via drive-by-wire (DBW). It is important to note that throttle control is a critical system which needs to be correct, and the BMW E46 throttle and intake system is a unique implementation with several details that require careful attention. The basic terms of drive-by-wire are as follows: the ‘gas pedal’ inside the passenger cabin is called the Accelerator Pedal
(DBW_APP1%), while the electronically controlled throttles in the engine bay are referenced as ‘Throttle’ (Throttle%, DBW1_TPSA%). Based on the measured Accelerator Pedal position, the ECU determines a desired DBW_Target position and moves the Throttle to that position.
As shown, there is a
Drive By Wire Wizard which must be used to calibrate accelerator pedal and throttle position sensors.
Although sensor calibration values from one vehicle may be close enough to work for another vehicle under some circumstances, it is absolutely necessary to run the Drive By Wire Wizard before running the engine for the first time. The wizard should be repeated if any components in the throttle control system are removed or replaced such as the throttle bodies, TPS sensors, throttle linkage, electronic throttle control motor, or accelerator pedal.
Please ensure the vehicle’s battery is fully charged (at least 12.5 Volts) before running the Drive By Wire
Wizard, as low battery voltage can result in abnormal sensor measurements. If a battery charger is available, it is preferable to connect the battery charger in 5A, 10A, or 20A mode and perform the Drive
By Wire Wizard while the battery voltage is near 13.5
–
14.0 Volts. When connected to the Infinity EMS with the engine OFF, go to Plug-in | Wizards | Drive By Wire Wizard. On the first page, be sure to check the ‘Calibrate Sensor Data Only’ checkbox before selecting ‘Start’. Follow the step-by-step instructions for each page.
The BMW E46 M3 SPORT button located in the center console (shown) still serves as a switch input to the
ECU. Contrary to some misinformed beliefs, this button never changed the maximum power output of the engine. This switch changes the accelerator-pedal to throttle-target relationship in the stock BMW DME.
These curves are configurable in the Infinity Tuner software using the DBW_ThrottleCurve1 /
DBW_ThrottleCurve2 tables, which allow the tuner to define the DBW throttle target based on
Accelerator Pedal Position and Engine Speed.

The ModeSelect_DBW table is preconfigured to switch between the two different
DBW_ThrottleCurve tables, depending on the status of the
CAN_SPORTBUTTON signal. The
CAN_SPORTBUTTON toggles between 0 and 1 (2 and 3 are not used) when depressing the
SPORT button. States 0 and 1 are mapped to the
DBW_ThrottleCurve1 and
DBW_ThrottleCurve2 tables respectively. Both 2D tables use accelerator pedal position for the y-axis and RPM for the x-axis.
The values that are entered in the table are throttle position targets.
When accelerator pedal is pressed, idle valve sends m ore airflow into engine. Airflow increases w hen LS5_Duty is set to low values.
Between 0-10% accelerator pedal position, the idle valve supplies all airflow to the engine while the individual throttles remain fully closed. This behavior can be observed in the LS6_Duty table (which increases airflow through the idle valve when the accelerator pedal is pressed) and the
DBW_ThrottleCurve tables. If tuners desire to adjust the DBW_ThrottleCurve tables, the lower two rows must remain set to 0. Great care must be taken when adjusting the ThrottleCurve tables, poor choices here can result in undesirable engine response or drive-by-wire tracking errors.
If it is desired to mimic the OEM BMW throttle control strategy, set the target to 75% throttle below 5500
RPM when the Accel Pedal is 100% open and 90% throttle above 5500 RPM. NOTE: Do not enter
values above 95% in the throttle curve tables; this will force the throttles against the mechanical ‘full open’ stop which is not desirable and could cause failsafe actions to occur.
Tuning Tool Tip: Because the AEM base session files use TPS as the VE table y-axis, the throttle target tables can be used as a tuning aid. Simply set the DBW_APP1 100% row to Throttle target values that correspond to values which need attention in the VE tables. This enables each cell to be accessed easily by the tuner on a dynamometer for example.
The factory BMW traction control and rev limiter is controlled using the DBW, whereas many other applications use a fuel cut or, in some rare cases, an ignition cut or ignition retard. With the AEM
Infinity, these can be controlled by any or all of the aforementioned methods.
Note that there is also a
DBW Tuning section in the
Plug-in | Wizards | Setup
Wizard… However, most of these channels will already be set up properly in the
AEM base session file and should not be changed.

There are a few integrated DBW fail safes incorporated into the Infinity system. The ECU constantly monitors the accelerator pedal sensor voltage and throttle position sensor voltages to ensure the signals are not excessively high or low due to damaged sensors, short circuits, or broken wires. The ECU also performs self-diagnostics to ensure the electronic throttle is following desired DBW_Target properly, that the DBW throttle control motor is not using excessive energy to move the throttle, and watching to see that all the redundant sensors are working together as expected. If any of these conditions are determined to be abnormal or unsafe, the ECU can shut the engine down to prevent unintended engine acceleration. When the ECU shuts the engine off due to problems detected in the DBW system, the
AEM Infinity notifies the driver by illuminating the Engine Malfunction Lamp (EML) on the dashboard. This error will reset when the ignition key is cycled or if the problem is fixed.
CAN BUS
The AEM Infinity EMS for the BMW E46 M3 supports the majority of the OEM features including:
Tachometer, Oil Temperature Gauge, Coolant Temperature Gauge, A/C Request Button, and Fuel
Consumption (MPG).
When the EMS is connected to a PC and changes are being committed either through table values or the wizard, the CAN transmission may occasionally pause and the gauges will drop out one at a time until they all stop working. This does not happen during normal operation.
Cycling the ignition switch will reset everything back.
NOTE: If the vehicle is used on rollers such as a dynamometer where the front wheels and rear wheels are operating at completely different speeds, the DSC light, the TPMS (tire pressure monitoring system), and the BRAKE light will illuminate as usual. When the vehicle is driven conservatively on a road, these 3 lights will be OFF like normal. However, if the tires experience any slippage, these 3 lights will flash ON/
OFF, warning the driver of traction issues. If the tires are excessively spun, these 3 lights may stay ON replicating a dynamometer speed test. If this happens, a simple cycle of the ignition key will reset these lights back to OFF.
The DSC light is not controlled by the Infinity but by the BMW VDC/ABS controller. The BMW VDC system, when enabled, may apply brake pressure to one or more of the wheels to maintain vehicle stability during spirited driving; the DSC light may briefly illuminate or flash during these events. If excessive wheel slip is encountered then the DSC light may remain illuminated for the remainder of the current power cycle as the Infinity is not configured to reduce torque during

these events as an OEM ECU might.
Rather than OBD2 diagnostics, the SES-Service Engine Soon light is now dedicated to the AEM
“MILOutput” feature. The AEM MILOutput activates if any 1 of the following inputs are in an error state: air temp, baro pressure, coolant temp, exhaust back pressure, fuel pressure, UEGO #1, UEGO #2, MAF analog, MAF digital, MAP, oil pressure, or throttle position. If any of these sensors are not used, they should be turned OFF in the Wizard to avoid any false readings. To activate the MILOutput feature, go to the Wizard and check “Enable MIL Output” in Diagnostics.
The red oil can light still illuminates if there is low engine oil pressure. However, it will no longer change to yellow when the engine oil level is low. But, if an aftermarket oil pressure sensor is installed, the oil can will illuminate yellow and beep if the AEM failsafe “OilPressProtectOut” is triggered. This feature needs to be activated in the Engine Protection section of the Wizard, as shown below left. Also, there is a corresponding RPM dependent “OilPressProtect” 1D Table that needs to be set up as well. When the oil pressure falls below this set value, the Oil Press Protect feature will be activated.
Rather than OBD2 diagnostics, the EML-Engine Malfunction Lamp on the dash warns the driver if the
“DBW_Error_Fatal” has been activated. If this happens, the engine will be shut down for safety and the error will reset when the ignition key is cycled and the condition that caused the error is no longer present.
The coolant temperature gauge’s red warning LED, located in the BMW gauge cluster, is programmable.
When the coolant exceeds the value entered in the channel “CoolantHighLEDLimit” the LED will illuminate (default = 100C).
The 4000
–
9000RPM red and yellow tachometer LEDs (shown) will now always match the current RPM limiter. For example, if the 2-step rev limiter is active and targeting 5000RPM, the tachometer LEDs will move the displayed “redline” to 5000RPM.
This happens even if the engine is idling and not actively banging against the 2-step limiter. If the 2-step rev limiter is
OFF, but the main rev limiter is set to 7000RPM, the LEDs will show the displayed “redline” at 7000RPM. If the 3-step rev limiter turns ON and changes the target rev limiter to 6500RPM, the LEDs will show the displayed “redline” at 6500RPM.
The main rev limiter is configurable in the setup wizard. The 2step and 3-step rev limiters are configurable in the setup wizard and in corresponding tables. Keep in mind, there are fuel cuts, spark cuts, ignition retards, and cut start windows. The tachometer LEDs are driven by the lower value between the fuel and spark cuts and ignores the ignition retard and cut start window RPMs.
The following channels on the BMW CAN bus are available for logging. The AEM traction control utilizes the CAN wheel speed sensors: CAN_FLWS [MPH], CAN_FRWS [MPH], CAN_RLWS [MPH],
CAN_RRWS [MPH]. The following steering channels are only for data logging: CAN_STEERANGLE
[deg].

The rate of fuel consumption (MPG) is calculated based on injector duty cycle, injector size, engine speed, etc. The output display will be close, but keep in mind there are many factors and variables. To customize and make completely accurate, there is a trim channel named “CAN_FUELFLOWSCALER”.

CRUISE CONTROL
Currently, a cruise control feature is not supported with the AEM Infinity. However, the multi-functional steering wheel buttons are run over the BMW MFL bus and are available for miscellaneous purposes described below. There are 4 buttons:
Enable, Resume Set, Accelerate+, and
Decelerate- (as shown).
The Enable button now engages the 3-step rev limiter channel “CAN_CCEnable”. A 3-step rev limiter is a simplified traction control based system that uses engine and vehicle speed or launch timer inputs to limit the RPM of the engine. To operate, first be sure the
3StepSwitch table is set to recognize the
“momentary” Enable button, as shown. Set the 3StepTargetFuel and/or the
3StepTargetSpark table’s first (0 MPH) cell to the desired launch RPM. When the Enable button is held down, the EMS will limit the engine’s corresponding RPM. Once the car is launched and the EMS begins to register vehicle speed, the RPM limit can then be tailored to prevent wheel spin using these tables.
The Resume Set button is used as an
AEM traction control switch. Note:
The DSC button is not available as it is a direct link to the VDC. The
BMW VDC system is disabled
when using the AEM Infinity. Instead, the latching Resume Set button changes the TC_SlipTargetTrim
1-axis lookup table (shown). Simultaneously, the Cruise Control icon on the dash is illuminated to inform the driver the status of the programmable AEM traction control. Normally this table is used with a multiple position switch. However, because the BMW Resume Set button is either OFF (0) or ON (1), only the first two cells of the table are used. Two possible traction scenarios, for example, could be ON/
OFF or aggressive/nonaggressive. To use this feature, it must be enabled in Infinity Tuner: Plug-Ins |
Wizard | Setup wizard | Traction Control | Traction Control Enable.

P/N 30-3510
The steering wheel’s Accelerate+ and Deceleratemomentary buttons increment and decrement the map switching function “CAN_MapValueNV”. This feature is extremely flexible as it can be used to switch VE tables, ignition maps, lambda targets, and boost levels.
When the Accelerate+ or Decelerate- button is depressed (or when KeyOn occurs) the tachometer displays 1k, 2K, 3K, 4K, 5K, 6K, 7K, or 8K momentarily representing the currently selected value of ModeSwitch. Because of the BMW E46 M3 tachometer range, 1–8 are the only valid values (9–12 are not used for this application).
For safety precautions, the AEM base session files come standard with the VE tables, ignition maps, lambda targets, and boost tables all set the same because the Accelerate+ or Decelerate- button could be mistakenly bumped.
In order to use this feature, care must be taken into account when setting up the tables and tuning. Enter the number of the table into the corresponding mode selection table for each feature (VE tables, ignition maps, lambda targets, and boost levels).
Key Off Commit must be enabled for map position selections, as selected via the cruise control buttons, to be saved across power cycles. If Key Off Commit is disabled then the map position will reset to its default position after a power cycle.

Step 15
As shown, use a pick to unlock this tab.
Pull the connector downwards to release it from the inner plastic “skeleton”.
Step 16
The internal plastic “skeleton” should now be able to be removed.
To allow space for the AEM EMS kit, the top portion (that the DME was secured to) will have to be cut into 2 pieces.
Using a band saw (or similar) cut the
“skeleton” along the dotted line as pictured.
© 2015 AEM Performance Electronics
Step 17
The pictured piece can be discarded.
Reinstall the other part of the plastic
“skeleton”. Reconnect the relays and white plastic connector from the previous steps.
Connect the AEM jumper box and the
90-degree locking comms cable to the
AEM Infinity EMS.
Insert the Infinity in a vertical position where the DME was mounted previously.
The 2 large Infinity connector cables should be facing upwards. Note: Infinity blue connector towards front and gray connector towards rear of vehicle.
Step 18
Connect the AEM jumper box to the 5 factory BMW DME connectors in reverse order (1-2-3-4-5). Place the jumper box on top of the AEM Infinity
EMS, as shown.
Connect the UEGO extension harness(s) to the “Lambda1” (and/or
“Lambda2”) 6-pin DTM connector(s). If using any AEMNet components, such as an AEM AQ-1 Datalogger, use the 4pin Deutsch DTM “AEMNET” connector.
Evaluate which ancillary sensors, inputs, and/or outputs will be required to run the vehicle. Using the aux pin-out information, wire the components into the included 12P connector. Plug this into the adapter harness connector labeled “AUX”.

Step 19
Before reinstalling the E-Box cover, cut half-circle slot(s) along the edge, shown in yellow. This will allow the comms and miscellaneous cables to exit the E-Box.
This kit requires a MAP sensor. Use the aux connector pinout to wire in a sensor and route the wires through the E-Box cover.
Using a 7/8” wrench, install the optional
AEM UEGO sensor(s) in the exhaust at least 36” from the turbo (if applicable).
Connect the UEGO extension harness(s) to the sensor(s).
Position everything being cautious not to pinch any of the cables. Secure the E-
Box cover with the factory fasteners.
This will be a very tight fit.
Step 20
To remove the cowl, disengage the 3 quarter-turn fasteners and remove the interior ventilation filter cover and micro filter element.
Unclip the 4 tabs for the cable duct in front of the cowl and separate the two long pieces. Make sure the engine is cool and pull the large cables out of the plastic retaining seats and gently lay them down on the engine.
Unscrew the four T30 Torx bolts and remove the lower section of the micro filter housing by pulling towards the front of the vehicle.

Step 21
Towards the back of the vacuum rail there is a barbed nipple (shown). There is a short 90-degree rubber hose (not shown) and corresponding hard plastic tube (shown) that connects the vacuum rail to the fuel pressure regulator under the vehicle.
Pull the short rubber hose off the vacuum rail. Be careful not to lose the hard plastic tube which will be zip-tied in place by BMW.
Step 22
Using the barbed TEE and rubber vacuum hose included with the kit, install the MAP sensor’s vacuum source, as shown.
Find a location to remotely mount the
MAP sensor. Be sure to keep the vacuum hose and electrical cables away from hot exhaust gas areas or moving parts.
Connect the MAP sensor to the auxiliary connector.
The electrical and mechanical installation of the BMW E46 M3 Infinity
EMS PnP kit is now complete.
