PNPECU MaxxECU M54 MS45.1 solution



This page refers to version 5 PNPECU M54 MS45.1 solution only. Make sure to check the adapter tag for your version.

21/5/2023 - Version 5 is latest.

PNPECU has developed the M54 solution to satisfy customer requests to allow the M54 engine to be fully controlled.


Adapter extra connector information



See bottom of this page for the pinouts of these auxiliary connectors

• 18 pin Auxiliary connector part numbers
  • Connector - https://www.te.com/usa-en/product-1-962692-2.html
  • Terminals - https://www.te.com/usa-en/product-5-963716-1.html

X6000-1 and X6000-5 terminals for spare functions (12V, GROUND, CANBUS HUB)

X6001 IS THE BLACK CONNECTOR

X6005 IS THE WHITE CONNECTOR

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



• MAF is not used - the signal is available in the adapter housing (X6003-27) if wanted.
• 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
• Coolant temperature - used as OEM
• Front bank pre-cat lambda sensor - used as OEM. Note this is a LSU4.2 sensor
• TPS sensor - used as OEM
• Vehicle Speed Sensor Rear Right - used for vehicle speed
• Knock sensors - used as OEM
• AC Compressor Enable - used as OEM via CANBUS
• AC Compressor Activate - used as OEM via CANBUS
• Clutch switch - used as OEM
• Oil temperature - used as OEM
• Steering wheel switches


M54 OEM Actuator Usage



• Ignition coil wiring
• Tachometer signal
• Fuel pump relay
• 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


Options at ordering



Not everyone is going to need or want the same thing with their ECU conversion.
