Great description GDC-SRT. As you can see it is quit the system.

Only thing I would add is:

1. Your skeem can accept up to 8 different keys.
2. SKEEM comes from the factory with the Vin encoded. I know this because the first one I received had to be sent back because it had the wrong VIN.

So I assume that if I take a SKEEM module from one car and put it in another car it will not work.

3. It would be interesting to know if the MB system can program the SKEEM's correct VIN without going to Chrysler.

When I was having problems with my panic button, I did get to listen in on a conversation with the Chrysler engineer (Person who was the orginal Chrysler person on the Xfire electrical system.) who was talking with a German engineer at Garmin (sp) so we could translate the problem/fix to our tech locally. Needless to say it was a super conversation. He was retired and was brought back as a consultant on the Xfire. He was very impressed with the German technolgy and I got the impression that Chrysler was waiting for the last Xfire warranty to expire to have a party. In my mind, Chrysler simply does not have the capabilty like Mercedes has to support their cars.

You may find this amazing. I had a A service done on my 2007 C350 4Matic at 24,000 miles. The next service is a B service at 36,000. That is 12,000 miles on the oil and filter and that is their warranty service. They only use Mobil 0-40 and fleece filters for that reason. Just checked yesterday and computer says 9000 till next service. I get to wondering so I do the oil and filter at 6000 miles between services by Mercedes. Old habits die hard.

 

The VIN number is encoded is just about every module. When you get a new module from a Mercedes dealer they need your VIN to get it and it comes with the VIN already encoded. With my V8 conversion, I got the donar ECU unlocked and coded it to the car in Developer Mode on the Mercedes STAR Diagnostic system. The repair techs at the dealership do not have developer mode but with this mode you can code control modules as long as you can speak german. There are some other interesting things you can do in developer mode like remove the speed limiter, and all kinds of other funky things like make your brakes lights strobe under panic braking.

Anyone know the part number of the SKREEM in a crossfire? I have tried to get into the anti-theft system with the MB STAR DAS system as various cars but but the SKREEM module keeps coming back as version unknown. If I have the part number I ran run it through EPC NET and find out if it was used in any other MB car. It it was I can enter DAS as that vehicle and interogate the module.

Just an FYI, I ran the stock part number of my na Crossfire ECU and it was very common to just about every 3.2L V6 Mercedes made. I did the same thing with a SRT ECU part number and got no matches at all. This seemed kind of strange considering the C32 and SLK32 and means the SRT had some different engine programming than the Mercedes with the same engine and could be the reason the SRT was rated at a lower HP.
