    Default Old T42 tune to new T42 requires updated operating system, segment swap?

    Hi all! Its been a while. I was chasing electrical buggaboes for years only to find my computer was bad. I was running an old holden tune and purchased a newer E38 and T42. The old tune was "segment swapped" and changed to work for the new computer.

    Unfortunately, he did not also update the T42. So I have a T42 with a stock tune that shifts very poorly. I would like to take the old TCM tune and put it into the new TCM. Obviously the operating systems prevent a comparison and update.

    The first tune is the old one I wish to use.

    The second tune is the new operating system with the tune I wish to over write (Tranny tune from fort Myers).

    Thanks in advance for any suggestions. The changes may be very simple but I cannot see what is different by comparison.
