Transmission compatibility
This is a complicated subject as at the time of writing there are solutions for external control of DCT, 6HP and 8HP transmissions out of BMWs, at the same time MaxxECU provides it´s standardized can bus output which multiple transmission controllers are able to make use of for just about any transmission out there.
There is no direct support for the original 4HP/6HP BMW TCU and is very unlikely it will ever exist.
For direct PNP communications with a stock BMW DCT transmission with a BMW TCU refer to this page - https://www.maxxecu.com/webhelp/advanced-bmw_dct.html
what this means is that the BMW TCU believes it´s listening and talking to an OEM BMW DME.
The MaxxECU is not directly controlling the transmission but sending and receiving signals that emulate the BMW DME.
MaxxECU is working on adding other BMW newer transmissions to the emulation compatibility list.
100% compatible with all manual gearboxes!
M54 OEM Sensors Usage

• VSS digital signal is not used - the signal is available in the adapter housing (X6003-40) if wanted
• Brake switch signal is not used - the signal is available in the adapter housing (X6003-41) if wanted
• Engine oil pressure switch - the signal is available in the adapter housing (X6003-24) if wanted
• Rear bank pre-cat - not used but available by adding external lambda controller. Note this is a LSU4.2 sensor
• Camshaft signals - used as OEM
• Radiator temperature - used as OEM

• Idle control valve
• Vanos control
• AC Compressor relay
• EVAP Solenoid
• DISA
• Electric fan
• MS54.1 uses BMW BSD protocol and the adapter has the MaxxECU BSD module. See below for the pinout.
CAN BUS Compatibility
The E46 the M54 originally came in did communicate with the rest of the vehicle via CAN BUS. Thanks to the MaxxECU it is possible to fit the engine into other BMWs also that require information via CAN BUS
5/11/2022 -
E46 - compatible with BMWs of similar vintage
E39 - compatible with BMWs of similar vintage
E9x - compatible with BMWs of similar vintage
MaxxECU provides OEM BMW CAN BUS output for the above BMW vehicles. It also supports a vast array of other cars which a M54 can be fitted to thanks to that. Refer to this webpage for latest options and relevant information - https://maxxecu.com/webhelp/can-oem.html
