    Just curious guys what's to be gained by changing the OS on the A40's other than a TCM swap I thought all 3 years pretty much shifted similar? Sure would be nice to be to flash one of these OS'sin the old TCM's (01-05) but wishful thinking LOL.

    I have a "Magic TCM" file, A40 like the early 2001 OS was.

    You mean one that has dumber learning and shifts a lot better? I think I might know which one you're referring to.

    Welcome to the misery of being at the mercy of the OEM, Ben it looks like the TCM sent back a couple of bad bytes which threw everything out of whack. The read routine in the A40 is really quite appalling.
    Sorry to say but you'll just have to try it again.
