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 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!

M30 Motronic 1.3 OEM Sensors Usage

---

• AFM is not used and that includes therefor the stock air temp sensor, unless the AFM is left installed.
• Narrowband lambda sensor is not used
• Idle / Part throttle / WOT TPS switch is not used - must be replaced with a variable TPS and stock wiring not changed


• HT lead cylinder identification - used as camsync, not required though in case it´s broken
• Coolant temperature - used as OEM
• Vehicle Speed Sensor Rear Right - used for vehicle speed
• AC signals from vehicle - used as OEM

M30 Motronic 1.3 OEM Actuator Usage

---

• Ignition coil wiring
• Tachometer signal
• Fuel pump relay
• Idle control valve
• Check engine indicator
• Fuel rate output

CAN BUS Compatibility

---

The M30 Motronic 1.3 has no CANBUS and so the MaxxECU CAN BUS is provided in the 18-pin auxiliary connector

18/11/2022 -
• 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 M30 can be fitted to thanks to that. Refer to this webpage for latest options and relevant information - https://maxxecu.com/webhelp/can-oem.html
