Anyone following this thread and in the Dallas area that speaks German? I will need a German speaking person to use the developer mode in the Star DAS system. I also found a good site that allows me to cross reference parts and all the cars that used the same part. I am entering the numbers of all the various models to find out which V8 MB has the most simularity. This will be helpful when I have to decide what car to enter when I start programing. Selecting Crossfire is not an option and selecting R170 SLK isn't an option either since they never had a V8. No matter what I select I am bound to have some errors when I try to program the ECU but I am am hopefull these can be worked out in developer mode. The site I mentioned above is www.epc.startecinfo.com It is free for a year. If anyone wants to try it out, once you are in do not try to put in your VIN number but instead hit F11 and you can enter part numbers and it will show you what cars used that part. You can then select a chassis and see the parts diagram. BTW, there are no Chrysler part numbers on our various electronic modules. They are all MB part numbers and start with the letter A. I ran the part number of our stock ECU and it was used in just about every V6 MB made with the 112 V6 engine.
