It's really kind of annoying that MB vehicles require the multiplexer to make it work. That thing costs a lot of money, but it's basically just a custom programmable bidirectional serial interface. The extra cables are simply there for compatibility purposes.
There's a lot of COTS hardware that could serve the same purpose without costing an arm and a leg.

Re: V8 Crossfire Conversion Diary
Well It now only two weeks until the swayp happens. I have been getting pretty nervous but hoping the engine will run so that i don't have to swap it back to V6. Karim (Kanzus) helped with the Key Gen which produces the DAS key that raises DAS to developer mode. I went through the process and just tested it Now when I first enter a car inDAS it gives me a warning in German which I assmume says "you are in developer mode so be carefull what you screw with. Developer mode enables you to change just about anything and is only in german as it was intended to be used in the factory to build prototypes and make adjustments to pre production cars. Eeric will be the intepreter while in Developer mode and he has also bought my other set of MB wheels for his SSB Crossfire.

Keep in mind that this hasn't been done in a Crossfire by anyone willing to talk about it so it is still pretty much therory. One thing that gives me hope is that Kanzus (search this thread) has done something very similar when he put a super charged V8 into a C240 V6 car and was successful using this approach. I remember Kanzus was getting an error for transmission over torque but I think he was able to resolve that. Developer mode is Grman only and is used by the factory to build prototypes and adjust pre-production cars. Every STAR system clones or otherwise has this feature but most mechanics have never used it. It is hard to find information since so few people use this mode. If you could get your hands on the Chysler system it may or may not have developer mode, but it would be pretty easy to program an unlocked SRT ECU to a n/a Crossfire. This was not an option for me since the Crossfire never had a V8.

Re: V8 Crossfire Conversion Diary
I'll have to watch your progress and think on this a bit more before I commit to the DAS. I really need to see how extensive it is (or not) as information on it is sketchy.
I see some benefits to your thinking but there is one problem with just switching to an srt tune. It will have too much spark throughout the map as it is for a lower compression motor. So I'd be looking at the DAS plus the AEM. In theory, I should be able to do what I need to do (as far as boost is concerned) with the AEM itself.
That said, depending on what it can change, the DAS might make what I have to do with the AEM and the stock ECU that much easier!
Here is the major question on my mind. Does it allow changes to individual settings or only to groups of settings via a .bin file from another vehicle?
If it is restricted to a .bin file per group (such as transmission) I am not as interested. If it will allow me to open the group "transmission" and give me access to edit shift points, torque converter lockup, and others (akin to my old Superchips Custom Tuning Software), I'm all over it!
If it can do all of that, then I'd be very curious why it wouldn't let you see the spark and fuel tables as well. Maybe it is a matter of finding them in the raw hex tables? So, I guess I'll wait until you get into it a little bit more and see if it makes sense. OR maybe I'll just pick it up and see for myself and sell it when I am done if it doesn't do what I want it to do...

This way you don't have to be dependent on someone else.

My goal is to just make the car operate as if it came stock with the V8. After that I would like to add a rear mounted turbo, or HPS supercharger or what ever I can get to fit to get the power up. I don't believe I will have room for the Rotrex or under hood turbo. When I get to that point I will be very interested in what you know. The STAR DAS ran me about $750 plus about $200 for a T30 IBM lap top computer. Or you can spend $30,000 for the same thing from Mercedes.

I believe I already posted this but this is the best explanation of DAS developer mode that I have found.

Re: V8 Crossfire Conversion Diary
How attainable is unlocking an ECU, SRT or otherwise, for the rest of us who aren't capable of getting our own copy of the DAS software? Assuming that this whole thing works will it benifit the many in any way? Oh and i wish the best of luck to you by the way cause a V8 converted crossifre would be lethal.
