Möglichkeit M4 auslesen

Postby Golf1_16V on Fri Nov 11, 2022 6:22 am

Guten Abend,
Ich habe ein altes Motec M4 Steuergerät in meinem Golf. Es ist im Jahr 2001 programmiert worden. Besteht die Möglichkeit die Daten vom Steuergerät zu sichern und eventuell auf ein neueres M4 Steuergerät zu übertragen.
Es muss aber gesichert sein das die Daten auf dem älteren M4 erhalten und unverändert bleiben.?
Im voraus vielen Dank

Translated to English:
I have an old Motec M4 control unit in my Golf. It was programmed in 2001. Is it possible to save the data from the control unit and possibly transfer it to a newer M4 control unit.
But it must be ensured that the data on the older M4 is preserved and remains unchanged.?
Many thanks in advance

Hi Dirk,

As long as the new M4 uses the same or a more recent firmware, you will be able to migrate the file from the old M4 to the new one. If the Firmware version on the new M4 is an older version, you will need to upgrade the M4 Firmware to use the file as they are not backwards compatible.

Guten Morgen,
Vielen Dank für Ihre schnelle Hilfe.
Gibt es eventuell eine Anleitung zum Auslesen des älteren M4.
Im Auto ist eine serielle Schnittstelle dafür vorhanden.
Nur bin ich mit der Software nicht wirklich vertraut.

Good morning,
Thanks for your quick help.
Are there any instructions on how to read out the older M4.
There is a serial interface for this in the car.
But I'm not really familiar with the software.

Hi,

The M4 user manual linked below has information on connecting to the ECU.
