At least you can get one of them as a working solution from another junked crossfire; unlike a SKREEM unit. I'm also still not convinced that the PCM/ECU becomes inoperable after 30+ attempts, because I've seen so much conflicting information around it; and the only one's claiming that that is indeed the case seem to be dealerships that have proven to be incompetent otherwise, and would be more than happy to sell someone a unit they don't actually need.
Yes, the ECM is VIN coded and also has an immobilizer code between the SKREEM and ECM that must match to enable starting. When the common start-die issue happens, it is often sudden. Long before 30 attempts to start. Even if you have had 30+ attempts and the SKREEM is actually the fault, a new SKREEM installation will fix the problem.
