Hello, I have an immobilizer issue and nobody can fix it so far. Is this device for sale already?

Thanks.

 

It depends on how many people really need help and what they expect for processing quality.
The module as I have installed in my Crossfire now is already able to help someone. He would only have to reprogramm his PCM.
But it would look like the one on the photos above.
Until a "presentable" product is reached, I think 6-12 months will pass.

 

Ah, OK. Thank you very much.

 

i think many will not care much if it looks like that, as long as it performs as needed.
and it does not look bad...

 

Ok but I had to solder all by hand, that takes a lot of time (I don't have) so I would do this only if someone needs his Crossfire and have no other option to solve this problem.

 

I don't want to take anything away from Viper-666 and his post, he knows a lot that I do not and I'm sure we will be using his parts in the future. However, we can confirm whether or not you actually need a replacement part. If not, we can reprogram it so it works again. Don't let your sweet ride sit waiting for parts it may not even need.

If it does need a new SKREEM, we have a few left over from previous jobs that we can reprogram for your VIN. However, we have had them for a long time because we rarely need them to fix a Crossfire no-start condition.

 

Essentially NONE of us can do that. Looks like this "sosxfire" guy, and Rob at Needswings, continue to be our only hope.

 

but, what about just eliminating the immobilizer? getting rid of it? bypassing it?
this would solve the problem.
i think Andre is considering this a second way and also working on it?
right, Andre?

 

no, wait a minute: reading his 1st post, he said:

" it was possible for me to find a way on which I want to replace the Skreem module "
so seems he is trying to REPLACE it, not eliminate it! using another instead. o well...
or there is a chance to do that?

 

Diesel trucks have spark plugs now? Or do you mean 'Glow-plugs?

I have also someone in the US who want to help me with my collective order and are able to program the PCM and of course sosxfire, needwings, Mobile Diagnostics and Programming and all other who are able to repair and program a Mercedes PCM could do that. I will make a detailed manual what to do, when you have the right programmer and are able to use it, this is not a big deal.

 

Yes, and when you DON'T have the right programmer, it IS a big deal.

 

I think the simplest solution is too get rid of the SKREEM altogether, toss it out the window. It being replaced with a gizmo that cares nothing about key codes, chips and halos etc. It just connects all the systems to get the car running. A simple kill switch hidden away and the car unlocked manually with just a key with no fob. The pump in the trunk just unlocking all of the locks at once. No lights fading away seconds after locking the car. Back to basics.
What I say above may be harder than I think but .....
I guess it is OK for me to say this as I do have a spare SKREEM, two keys and too many years on my time clock. Which reminds me I have to take the mandatory driving licence test for old geezers in a month. So if a SRT comes up for sale you’ll know why. 🙄

 

Don't worry Dave, my FIL turned 80 last year and passed the mandatory DL test. If he can pass it, anybody can.

 

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.

 

By the time I do my test my cataracts should be fixed, and when they tell you to draw a clock I’ll ask them if they want red or green numbers. 😉
My buddy said it was a doddle, they asked him why it said he needed glasses to drive and he told them his eyes had been fixed.

 

So if we are running now and no problems, then it will not need to be programmed and be a plug and play.

So this could be a mandatory preventative maintenance.
all depending on the cost.
but completly understand on wanting to get the finish product completely done before you figure the price and let us know.
I am sure several are curious about what price range you are shooting for.
If it would be cost effective enough for a preventative maintenance, or be more in the range of holding off till it is needed.

Sounds like what you have a generation 1 atm
And in the 6-12 months a gen 2

Definitely time consuming soldering all the wires, once you have your board set up how you want and can etch it and much less wires to solder

Unless you have a electronics college close and have the class practice there soldering skills

TY for your work.

 

I wouldn't worry about a kill switch, what these fancy keys are for.
If I was, I would add a aftermarket alarm.

Like, who cares at this point if the dash is coded and matches.
would be nice if the ecu just ran the car without all the security.
But with our 1/4 million $$ cars would need the security lol
but even the work it would take to rewrite the coding in the ecu so it does use all of the security would be a nightmare.
if there was something to plug in the line going to the ecu tricking ti that all the security is good, but if that were that easy, I am sure it would have been done years ago.

 

Exacly!

If you mean you can buy the Skreemulator and put it away like a spare Skreem, no this wouldn't work plug & play. You have to buy the Skreemulator for defective Skreems and when your Skreem dies you have first to program the PCM for the Skreemulator.
But you can do it in the other way, read out as many codes (max 4000) from your Skreem. Let the Skreemulator in the Crossfire put the original Skreem away and if you want to go back, maybee because you want to sell the Crossfire in original shape, put the Skreem back in and the Crossfire works. You maybee only loose some codes who are stored on the Skreemulator and aren't used.

That's right. Because I have to know what components I finally need and what they will cost.

Not exactly. It would get a gen 2 with a amount of 5 pieces for a beta test. One for me and four for them who are willing to test the Skreemulator and use the Crossfire as a daily drive,
Than it gives a Version 2.1 or 3 depending if there are any problems.

The Gen 2 and the final product will be make by a professional company. The prototype I made is only to verify if all works like expected. It is a cheap and fast way to do that.

Hopefully you don't need that. If all gets like I planed my Skreemulator works like the original Skreem, with the benefit that it doubles the codes your skreem has left and can used with my preprogrammed EEPROMS (where you have to program your PCM) ever and ever again.
Means only the way you unlock your car and the immobilizer changes from RF and Transponder to RFDI tags. Wo are cheap and I would send 10 pieces with a Skreemulator. So don't have to be worry if you loose one

Sorry, this wouldn't happen with my solution, because you have to find a way to disable the immobilizer in the PCM. I have an idea how something like this could work but I have to test it myself first and it would mean that something has to be changed on the hardware of the PCM and you still need some kind of a Skreememulator but it would have to send the same code all the time.
But the advantage of doing this once will be, it works forever.
But this is only a theoretical concept at the moment.

 

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.
