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.

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.
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.
