I hacked the Skreem, the Skreemulator
It appears that your entire idea is theoretical. Your thread title is: "I hacked the Skreem..."' but this is misleading; people think this means you have a fix for their car.
You already have people thinking you have developed a solution. More accurately stated: You are, perhaps, close to a solution.

I don't have a product ready and this will take 6 to 12 month is because I have to make the develope in my spare time. I'm not a company who has many people work on this 8 to 10 hours a day.
But on the other hand I think my module will also be cheaper because I'm not a company who has go get back 2 years of development 😏
I did not say "I think" I said "it appears".
I do not mean to give you a hard time, but many have cars sitting now because they can't get SKREEMS.
DO NOT misunderstand, I WANT you to be successful.

Maybe I expressed it wrong, I don't mean that you have to buy a programmer, but that there are many who can program the PCM.
And it only needs to be programmed if somebody has a defective skreem, with all others no programming is necessary, my module runs plug & play with them.
And as i said, the person who sells my module in the us will be able to do the programming if necessary.

That is the only way I can say it, it scares me. HOWEVER, fact is, you have done what we all dreamed of - you have not just hacked the SKREEM, you have hacked the PROBLEM.
I shall leave the PCM programming to those who can do it - I do not yet understand the logistics it will take to get a car going, using your ideas and insights - but it has become apparent that this IS our way forward.
I believe that, for now, the rest of us must be patient and let this process and product evolve to where the product itself is finally readily available.
I DO see how that will take time.
Sorry, I am not a native English speaker, so I beg your forgiveness if I confuse such nuances.
Also, what I write may not always reflect what I mean, as translation problems can creep in.
Since I know how the Skreem works together with the PCM it is not theoretical for me. I admit to you that the proof stands out, but only because of lack of possibilities. Unfortunately I do not know of any Crossfire in Germany which has this problem.
And because in such a case the PCM has to be reprogrammed, help in the US (in this time) would only be possible if someone sends his PCM to me. When my module is ready, it will come with instructions on what to program, so that anyone who can describe EEPROMs can do this themselves or my partner in the US who will distribute my modules to you will also offer this service.

Oh,we have a translation issue. I sent you a PM just now.
Sorry, sir. I have been being too precise with my English.
Please accept my public apology!

Apology accepted.
Was meaning if was cost effective, to purchase and plug in as a preventative before I have a problem.
if I didn't drive so much I would be more than willing to help test, outwith how much driving I do, I would hate to get stranded 3 to 16 hours from my house.
if I worked local, then if something happened, I could just get a ride home and get my truck and a trailer and haul home.
But if I kept my skreem and my car and just had to plug back in, if it would even work, or if codes would be off and would have to get ECU work done for it to work again.

And yes if it gives a problem with my module you have always the possibility to swap the Skreem back in, you loose only some codes who are left in my module, they wouldn't work after you swap the Skreem back, you have to read out first new codes.
Yes of course more starts is better and the miles doesn't matter, was just mentioning it would suck if on ho home day states away and i go to start my car and nothing
lets see: seems to me that there are 2 ways we can use your module:
1-to plug it into the circuit so it replaces the stock immobilizer, and:
2-to keep as a spare in case the stock fails, so we can plug it in. sort of spare tire.
then, how this connection would be? (i imagine sort of connector hidden but easily reached)
what we have to do in advance to be prepared? (like what we have to open/cut/solder)
details?
i believe we all will benefit when learn this.
thanks

If the Crossfire starts it will running till you shut off the motor. After starting the Skreem has nothing to do. So for my test the distance you drive is not so important. If you start your car 10 times or more a day this would help more as if you start drive 100 miles, start again and drive back.

I am sure you could describe it very accurately in German and if we could get a technical translation from someone here we would get the information accurately.
sketch?
wonder if you (Andre), or somebody else with knowledge on the crossfire electronics, could draw sort of a sketch to show how the components connect-and influence- the whole performance of it?
which determines what other(s) will do whenever something happens...got my point? something that does not require great detail, and does not take much time to do.
simple, for us that dont have much knowledge on the subject.
like the ECU as the sun, and the others like planets-and some with satellites...but all interconnected (i hope am clear enough).

I think I have to buy all used Skreem modules... The advantage would be that I'd have also the right case, but I'd have to solder everything off and on... a lot of manual work.
I have got lost somewhere along the way reading this thread, I wonder if anyone on this forum could translate the basics of this module of yours accurately if you wrote the description in German. We are getting lost due to language problems, I admire your skills in English but describing technical information requires a special skill rather than a conversational skill.

If your Skreem already works this would the way to go.
Of course you can do it that way with my preprogrammed EEPROMs but then you have to let progamm your PCM so that it accept this codes.
That is the hardest thing I am working on. I found out, that the big plug is from TE Electronics but Daimler has there Hands on it and they can't give any Information about that. But this doesn't matter because you can buy them from Mercedes a little pricey but you get them. But the other side where you plug this in is a whole part of the skreem module and that you doesn't get to buy. Maybe someone here has connections to TE Elektronics, they have similar plugs listed and I buy also one set, but the Mercedes plug don't fit.

of course, this is for those who can solder-and are willing to do so. i wouldnt mind doing so. even provide the links for the connectors to fit.
then we may peel off the wires and solder a male/female adaptor of any kind we can get, in a "y" extension that fits whatever connector you have or can find and still leave the stock available.

I don't think this is the solution, there are many things that could go wrong if you put the wrong cables together and not everybody can solder.

as i said: "of course, this is for those who can solder-and are willing to do so " and also, have to be careful not to make mistakes.

Hello,
after more than 2 years of research and development and more than 1000€ of hardware costs i managed to understand how the immobilizer between engine control unit and skreem works.
And it was possible for me to find a way on which I want to replace the Skreem module. The first (and maybe most difficult) step is to unlock the immobilizer with my hardware and then start the car. This is done
The first prototype on a breadboard is finished and working.
See:
Youtube Video
The next steps are to build a second prototype on a perfboard and install it in my Crossfire to do a long term test.
At the same time I still have to find solutions for the remaining functions of the Skreem module like opening and closing the car, deactivating the alarm system etc.
The goal of the project is to replace the existing Skreem module 1:1 with my "Skreemulator".

That is a fantastic achievement! Congratulations - hope to be able to buy one. - one day :-)
