    Great info. Do you know what the "interp: at" strings mean? Also, what year/model PCM this was?

    Re: Flash Protocol

    I just joined the forum this morning - maybe I can help? I've got an MSEE degree and 18 years of electronic product development experience, but I need to get myself up to speed on the nut you're trying to crack. Pointers to useful threads (besides this one) and other sources of info are most welcome!

    Gotta warn you, though, I'm a hardware guy. The last coding I did was in grad school.

    Okay, the Ease Programmer uses the GM SPS software to reprogram the PCM to stock conditions only. There is no software Yet to allow us to upload our own PCM edits. The serial datastream is not encrypted, and very possible to create a program to use your own stuff.. Very soon I am dropping my programmer off at my friends house and he is going to start to look into it for me.. Hope to have something very soon.... He owes me big time...
