AiM Infotech BMW 1 Series (E87), 5 Series (E60) OBDII+ECU Connection Release 1.02 This tutorial explains how to connect BMW cars to AiM devices. 1 Car models and years Supported car models and years are: • • BMW 1 Series (E87) BMW 5 Series (E60) 2004-2006 2003-2010 2 Available connections These car models can be connected to AiM devices through the OBDII plug or going to the car ECU. 2.1 OBDII Connection These BMW cars feature a bus communication protocol based on K line on the OBDII plug placed on the car driver side, left of the footrest. 1 Connector pinout as well as connection table are shown here below OBDII connector pin Pin function AiM cable 7 K Line K line Please note: if you choose this connection we recommend you to use AiM cables to connect AiM devices. Their part number are: • • • ECU Bridge with OBDII plug EVO4 cable (to be plugged in EVO4 connector labelled RPM) SoloDL cable with OBDII plug • • MXG MXL2 X90BGCK12MA V02563050 V02569010 (2m length) or V02569090 (1,2m length) 37 pins standard cable 37 pins standard cable 2.2 ECU Connection These BMW cars feature a bus communication protocol based on CAN on the car ECU. Regardless of the stock ECU installed on your car, colours of the cables are always the same, they are twisted and here below they are indicated. Pin function BMW ECU cable colour AiM cable label CAN High Blue/Red CAN+ CAN Low Red CAN- 2 In alternative they can be as below. Pin function BMW ECU cable colour AiM cable label CAN High Black CAN+ CAN Low Yellow CAN- 3 AiM device configuration Before connecting the ECU to AiM device set this up using AiM Race Studio software. The parameters to select in the device configuration are: • • ECU manufacturer “OBDII” and ECU Model "ISO9141_2" if you are using the OBDII plug ECU manufacturer "BMW" and ECU Model "BMW_PT6" if you are using the car ECU 3 4 Available channels Channels received by AiM devices changes according to the selected protocol. 4.1 Channels available with "ISO9141_2" protocol Channels received by AiM devices connected to "OBDII" "ISO9141_2" protocol are: ID CHANNEL NAME FUNCTION ECU_1 OBDII_RPM RPM ECU_2 OBDII_SPEED Speed ECU_3 OBDII_ECT Engine coolant temperature ECU_4 OBDII_TPS Throttle position sensor ECU_5 OBDII_IAT Intake air temperature ECU_6 OBDII_MAP Manifold air pressure ECU_7 OBDII_MAF Manifold air flow ECU_8 OBDII_FUEL_LEV Fuel level ECU_9 OBDII_PPS Pedal position sensor Please note: channels listed above are those polled by AiM devices. They may or may not come across in the data stream depending on models. RPM, TPS,ECT and speed are generally available. 4 4.2 Channels available with "BMW_PT6" protocol Channels received by AiM devices connected to "BMW" "BMW_PT6" protocol are: ID CHANNEL NAME FUNCTION ECU_1 RPM RPM ECU_2 PEDAL_POSITION Throttle request ECU_3 SPEED_BMW Speed ECU_4 SPEED2_BMW Speed 2 ECU_5 WHEEL_SPD_FR_LF Front left wheel speed ECU_6 WHEEL_SPD_FR_RH Front right wheel speed ECU_7 WHEEL_SPD_RR_LF Rear left wheel speed ECU_8 WHEEL_SPD_RR_RH Rear right wheel speed ECU_9 STEER_ANGLE Steering angle position ECU_10 CLUTCH_SWITCH Clutch switch ECU_11 BRAKE_SWITCH Brake switch ECU_12 BRAKE_PRESS Brake pressure sensor ECU_13 BRAKE_PR_FR_LF Front left wheel brake pressure sensor ECU_14 BRAKE_PR_FR_RH Front right wheel brake pressure sensor ECU_15 BRAKE_PR_RR_LF Rear left wheel brake pressure sensor ECU_16 BRAKE_PR_RR_RH Rear right wheel brake pressure sensor ECU_17 WATER_TEMP Engine coolant temperature ECU_18 OIL_TEMP Oil temperature ECU_19 TEMP_OUTSIDE Intake air temperature ECU_20 MAP Manifold pressure ECU_21 GEAR Engaged gear ECU_22 ACC_LONG Longitudinal acceleration ECU_23 ACC_LAT Lateral acceleration ECU_24 GYRO Gyroscope ECU_25 DISTANCE_KM Distance 5 ECU_26 FUEL Fuel level ECU_27 BATTERY Battery level ECU_28 FUEL INJ Fuel injection ECU_29 ABS_STATUS ABS status ECU_30 MIL Malfunctioning indication lamp ECU_31 DSC_STATUS Dynamic stability control status ECU_32 ENG_TRQ Engine torque ECU_33 TPS Throttle position sensor ECU_34 DCT_TMP Dual Clutch Transmissions temperature ECU_35 DRIVE_MODE Drive mode Technical note: not all data channels outlined in the ECU template are validated for each manufacturer model or variant; some of the outlined channels are model and year specific, and therefore may not be applicable. 6
