PNPECU MaxxECU M50 VANOS 413/506 solution
This page refers to version 3 PNPECU M50 VANOS solution only. Make sure to check the adapter tag for your version.
19/4/20232 - Version 5 is latest.
PNPECU has developed the M50 solution to satisfy customer requests to allow the M50 engine to be fully controlled
Adapter extra connector information
• 8 pin Auxiliary connector part numbers
• Connector - https://www.te.com/usa-en/product-284869-1.html
• Terminals - https://www.te.com/usa-en/product-5-963716-1.html
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!

CAN BUS Compatibility
The E36/E34 the M50 originally came in did not communicate with the rest of the vehicle via CAN BUS. However, thanks to the MaxxECU it is possible to fit the engine into other BMWs 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 M50 can be fitted to thanks to that. Refer to this webpage for latest options and relevant information - https://maxxecu.com/webhelp/can-oem.html
