How to tell what kind of Siemens ECU I have?

Postby Knightmare69 » Thu May 29, 2014 4:00 pm

I'm trying to find tuning info on my wifes' 2010 MB w204 C200 CGi (i4 turbo) I've been told that it is a Siemens ECU and is locked which is why no tuners want to deal with it. That itself led me to this site and I am hoping to get some more information and to hopefully find a way to properly tune our car. Having said that, how do I read the info on the label of the ECU to even confirm that it is a Siemens? Thank you.

Hi!
You have SIM271. This is Siemens (Continental).

Great thanks, is this ecu unbackable? That's the response I've been getting from all the major Benz tuners. Thank you.
