PNPECU MaxxECU M62tu ME5.2.1 solution
This page refers to version 2 PNPECU M62tu ME5.2.1 solution only. Make sure to check the adapter tag for your version.
10/11/2022 - Version 2 is latest.
PNPECU has developed the M62 solution to satisfy customer requests to allow the M62tu engine to be fully controlled, the ME5.2.1 is a 5 plug ECU while the ME5.2 is the single 88pin plug. It´s important before ordering that you are aware of what M62tu engine loom variant you have.

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!
