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:

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.

Component

Wiring

Fuel Press

This is used for monitoring fuel pressure input to the Infinity. It can also be used to increase or decrease injector fuel pulse to compensate for a failing fuel pump.

Typical electronic fuel injection fuel pressure varies 30–100psi.

AEM carries 0–5V fuel pressure sensors (sold separately).

This w ire goes directly to the signal wire of the pressure sensor.

Air Temp

Air temperature is typically used for fuel and ignition timing correction.

The S54 comes standard with a MAF sensor which has an integrated intake air temperature sensor. This w ire is run in parallel with the stock sensor. This means if an aftermarket sensor is to be wired using this pin, the factory MAF sensor must be disconnected or else the signal will be skewed drastically.

AEM carries air temperature sensors (sold separately). How ever, the Infinity can accept any thermistor sensor and can be calibrated in the Infinity Tuner software.

Intake air temp sensors have two wires with no polarity.

Sensor Ground

Isolated ground for inputs.

This is not the same as a power ground or chassis ground.

This is shared for the Fuel Press, Air

Temp, MAP (Manifold Press), Ethanol Sensor,

etc.

This should be wired to the ground pin of the following: Fuel

Press, Air Temp, MAP, and Ethanol Sensor.

5V Reference

5 volt supply for the following aux inputs.

When measured with a voltmeter, it is normal to not measure exactly 5V.

This is shared for the Fuel Press,

MAP (Manifold

Press)

Manifold pressure is used for speed density fuel calculation, ignition timing correction, 02 feedback, boost control, variable valve control, ancillary outputs, etc.

Electronic fuel injection is calculated in absolute pressure not gauge pressure.

AEM carries MAP sensors (sold separately). How ever, the Infinity can accept any 0– 5V pressure sensor and can be calibrated in the Infinity Tuner software.

This should be wired directly to the MAP sensor's signal pin.

Ethanol Sensor

This is used for customers who are converting their vehicle to utilize ethanol fuels such as E85 or E98.

This digital input can be used for other functions as w ell.

The GM Fuel Composition Sensor (FCS) is the most commonly used for converting a vehicle to flex fuel.

This pin needs to be wired directly to the signal pin of the fuel composition sensor.

Boost Control

Solenoid

This is used to operate a 12V PWM solenoid.

Boost control solenoids can be normally open (NO) or normally closed (NC). This w ill change the duty cycle strategy but is also depends upon how the wastegate is plumbed with hoses.

AEM carries boost control solenoids (sold separately). How ever, the Infinity can control most factory boost control solenoids.

Solenoids have two wires and have no polarity.

Power from

Relay

Can be used for many things, however, this 12V source was implemented to be paired with the Boost Control Solenoid.

This 12V is coming through the vehicle's main relay.

Because of using shared power, this should only be used for low current electronics.

Cutting fuel and/or cutting spark and/or retarding ignition timing when shifting gears w ithout releasing the throttle pedal.

Cut time is typically 200300mS. Ignition retard is typically 20degree with a 50mS ramp-in time after the fuel cut. Ignition cut is not commonly used.

AEM 12 Position Universal Trim Pot (or typical potentiometer). Can also be used with any simple ON/OFF sw itch.

This w ire should be routed to the signal output of the component. If used with a simple ON/OFF sw itch, route the opposite terminal to an Infinity sensor ground.

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.

P/N 30-3510

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.

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.

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

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.

2001–2006 BMW E46 M3

When accelerator pedal is pressed, idle valve sends more airflow into

engine. Airflow increases w hen LS5_Duty is set to low values.

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.

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.

P/N 30-3510

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.

2001–2006 BMW E46 M3

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].

P/N 30-3510

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”. The default value is 9.6.

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).

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.

2001–2006 BMW E46 M3

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

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

be mistakenly bumped.

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

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).

INFINITY EMS INSTALLATION

Open the trunk and disconnect the battery.

Open the hood and locate the E-Box on the left side near the firewall. This is where the factory ECU (Digital Motor Electronics or DME) resides.

Remove the four screws using a T25 Torx wrench (late models) or 5mm Allen wrench (early models). Simultaneously pull up and rotate the E-Box cover to release it from the vehicle. This will be reused.

There are 5 DME connectors. These must be removed in a sequence from the left to the right (as pictured) or connector 5-4-3-2-1.

First remove connector 5 using your thumb by squeezing the release tab. Hold down and pull upwards.

Step 1

2001–2006 BMW E46 M3

Step 2

Connectors 4, 3 and 2 all have a swinging latch. First press the “button” and then rotate the swing latch downwards towards the DME.

Note: When reinserting connectors into the header, the swing latch must be open for initial engagement.

The connector will automatically push itself away from the DME connector’s header.

After removing connectors 4, 3, and 2, remove connector 1 the same way as connector 5 using your thumb.

Step 3

Step 4

P/N 30-3510

Step 5

To remove the DME (stock ECU) from the internal plastic “skeleton”, push the two tabs away from the bottom side of the DME, as shown.

Simultaneously unlock the plastic tabs and pull the DME up and out of the engine bay.

The stock DME will NOT be reused.

Step 6

2001–2006 BMW E46 M3

Next, there will need to be room made for the AEM Infinity EMS and jumper box to fit within the E-Box compartment.

Note: Some of the instructions below may slightly differ from vehicle to vehicle.

Unplug the 2 white connectors (shown) by squeezing each connector’s locking tabs.

Note: These two connections will be reconnected later.

Using a flat blade, such as a screwdriver, unlock the black fuse block’s tab, as shown, and lift upwards.

Step 10

2001–2006 BMW E46 M3

Carefully pull the internal plastic mount upwards a few inches to unlock it from the base.

Cut the factory cable zip-ties to release the BMW wiring harness from the internal plastic mount using a pair of long-reach dikes.

Cut the zip-tie shown.

Step 11

Step 12

P/N 30-3510

Step 13

There should be 2 cable ties to cut in the area shown.

Pull the internal plastic mount further away from the vehicle and cut the zip-tie shown.

Step 14

2001–2006 BMW E46 M3

As shown, use a pick to unlock this tab. Pull the connector downwards to release it from the inner plastic “skeleton”.

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.

Step 15

Step 16

P/N 30-3510

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.

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”.

2001–2006 BMW E46 M3

Step 18

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 EBox cover with the factory fasteners. This will be a very tight fit.

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 19

P/N 30-3510

Step 20

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.

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.
