As the mechanic level will be terminated soon: normally at monday 18-05-09, I will start level 2 of my CLK V6 to V8 55K project conversion which is electronics.
I have many idears and 3 possibilities to approach the problem:
1- simply use DAS Developper mode to encode the ECM and EGS ECUs;
2- swap EEPROMs from ECM to another;
3- make ECM virgin and recode it within normal DAS Module;
I tried DAS training module to see how developper mode works, and it's very interesting, espacially it is possible to recode ECU without SCN number which is only can be provided by MB itself.
My Goal is to start the car first, I hope it will start from the first possibility (DAS Dev). At a second time I will test the others and provide community a how to do manual : HOW TO HACK MERCEDES-BENZ ELECTRONICS
.
I found an interesting software to virgin the ECM, but have to desolder EPROM reprogram then re-solder it.
How do you think about my approach?

My understanding from the guys I am working with is to unlock you computer which gets rid of IMMO data and then use the Star Diagnotic system to re-associate the ECM to your car. Be careful becuase an unlocked ECM will re-lock the third time the key is turned. I think developer mode can be useful to reslove other issues if needed such as gear ratios in the trans and diff. Again this is information from the smartest guys I could find over here but they have not attemped a V6 - V8 engine swap so they can't be 100% sure it will all work until we try it. They have warned me that there is a possibility that I could end up with a V6 back in the car. I wish I could play with the system myself and see what is possible. But I am hoping that you will have information that I can share with my tuner so that the V6 does not end up back in the car.
One thing that all the pictures confirmed to me is that it is all done with standard MB electronic hardware which has been programmed, which leads me to believe the better you can use the Star system the more likely you are to succeed. You may want to consider sending your donor ECM to Beckman and have them unlock it. Their business is built on allowing mechanics to offer reconditioned ECM's to customers at a much better price than having to buy a brand new one costing thousands.
