    I just tried to read with V1.05. When I click on "Identify PCM" I get an error message "Failed to Read Block10"
    Here is the .bin from that PCM read out with Tunercat. It is a 2007 PCM #12602801 with a 2004 calibration OSID #12587603

    Is the connection to the pcm ok, ignition power on? Thats what it'll say if it can talk to the avt but the pcm isnt replying (block 10 is the first thing it tries to read).

    I just got into work. I won't be able to check it for about 10 hrs. I will try it again tonight.

    V1.05 works great. The problem was on my end----Sorry about that. I did have a bad connection. A connector was not fully seated.

    Excellent, thanks for the report

    I think I might add a usability tweak and put an error about check your connections in, instead of just "failed to read block 10" which is not so clear.

    Since you got LB7 Diesel flash in there too now!

    Wonder if read write can be added for 96, 97 and 98-00 Vortec Black Box PCM?

    Well, the duramax just happened to work. You can try a black box PCM, but Its an early enough generation that I do not expect it to work. I wont say never for write support, but at this stage it will only be if the pcms happen to be compatible with the 0411. Register interest in this thread though.
