PNPECU MaxxECU Street M30 solution



This page refers to version 3 PNPECU MaxxECU Street M30 solution only. Make sure to check the adapter tag for your version.

18/11/2022 - Version 3 is latest.

PNPECU has developed the M30 solution to satisfy customer requests to allow the M30 engine to be fully controlled


Adaper extra connector information



• 8 pin Auxiliary connector part numbers

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 - not used - ignition box provides up to 6 ignition signals from the 14pin connector
• 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 8-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


Options at ordering



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

Ignition outputs
• Stock single ignition coil - as OEM
• IGBT Output box - usually for Bosch Wasted spark coil install
• VAG R8 coils and connectors - PNPECU supplied R8 coils and connectors, customer will install the coils and add their own wiring loom to coils


MaxxECU DCT Adapter loom

This is a selectable option so that the webstore doesn´t incorrectly calculate shipping cost

EGT Sensor

This is a selectable option so that the webstore doesn´t incorrectly calculate shipping cost

For Street direct wiring is not possible and a CAN BUS EGT box is recommended (not available from PNPECU)


• Single is for when you are planning to monitor pre turbine inlet temperature
• Dual is for when you are planning to monitor pre turbine inlet temperature on a twin setup or each side of the engine
• Six is for when you are planning to monitor individual cylinder temperatures

Injector

This is a selectable option so that the webstore doesn´t incorrectly calculate shipping cost
