MTM Chips

While were on the subject of MTM chips i found this in a friends car, will open it up and see if the chips are the same. Odd thing is it came out of a standard S2

Yes,

Thanks. So that goes to my point that *original* MTM chips were supplied with an encryption board, at least at some point, e.g. 1998 as per the date on your chips.

It could be indeed the MTM chips were coming with daughter boards after a certain date. My Avant had a MTM treatment 1,5 months after it was first registered in Germany, not having a daughter board. I have the MTM bills and TUV registration all on papers. My Avant is from March 1993 btw.

Too bad I have sold the MTM chips ages ago, otherwise I could have made pics. My ECU has a green MTM label though.

I saw an ECU with red label with dates marked to 1994 and there were no encryption boards.

I am somewhat sceptical about the chips now, they dont have any handwritten labels, and if they did they have been covered up with yellow labels from a label maker, one says motor and the other says boost.

Think i shall just bin them, unless anyone has any other ideas that could help me ID them as Gen componants.


thanks

Do you have an EEPROM programmer? If so, dump their contents and send the bins to me. I can ID them.
