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!

M50 VANOS OEM Sensors Usage

---

• MAF is not used - the signal is available in the adapter housing (X6003-27) if wanted.
• Lambda sensors are not used
• Air temp sensor is not used - new fast sensor is supplied through stock wiring in PNPECU ECU kits not adapters - fit BMW 13622243946 (M12 threads) to have a fast-acting sensor in the intake, otherwise fit an extension to the air temp sensor and fit the new sensor in the intercooler piping.
• Knock sensors - not available in the MaxxECU Sport


• Camshaft signal - used as OEM
• Coolant temperature - used as OEM
• TPS sensor - used as OEM
• Vehicle Speed Sensor Rear Right - used for vehicle speed
• AC signals from vehicle - used as OEM

• AC Compressor Enable - used as OEM
• AC Compressor Activate - used as OEM

M50 VANOS OEM Actuator Usage

---

• Ignition coil wiring
• Tachometer signal
• Fuel pump relay
• Idle control valve
• Vanos advance
• Check engine indicator
• AC Compressor relay
• Fuel consumption output
• EVAP Solenoid

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
