I think I found some errors in the Transmission Calibration->Cruise section. The min and max values seem to be reversed on a lot of the parameters. Max is 0 and min is 65536. Whenever you edit the value it automatically jumps it to 511.

Good catch! Thanks Phoenix for fixing!

If you are both happy and Phoenix's is the latest, please update the first post and remove my note sending users to the one later in the thread. I might save someone downloading the wrong one. Thanks

I'm pretty sure I found the parameter that causes the 10 second wait before you can unlock the PCM, but when I change it, the check sum doesn't get updated, so I haven't been able to test it yet.

Does anyone know how to get TunerPro to fix the checksums outside the calibration section?

You figure out the right checksum plugin, or you use universal patcher to fix it. https://universalpatcher.net/fix-checksums/

If you look in the xdf (as an xml file) down the bottom you see

Code: Select all

<XDFCHECKSUM uniqueid="0x76F5">
    <title>GM P01/P59 checksum plugin</title>
    <REGION>
      <pluginmoduleid>a8d1fdd7-d985-4b09-9979-2735b69cc9a6</pluginmoduleid>
      <datastart>0x0</datastart>
      <dataend>0x0</dataend>
      <storeaddress>0x0</storeaddress>
      <calculationmethod>0x0</calculationmethod>
    </REGION>
  </XDFCHECKSUM>

If you google a8d1fdd7-d985-4b09-9979-2735b69cc9a6 you land in https://github.com/joukoy/gm-checksum-p ... ecksum.xdf

If you step out a level, and guess its GM-P01-P59-checksum-plugin.dll in the same location and look at that dll in a hex editor you indeed see the matching GUID. So the plugin is https://github.com/joukoy/gm-checksum-p ... plugin.dll

Thanks for the info about the checksum stuff. Universal patcher sounded easier though, so I went with that.

I set the new time to 1 second, out of concern that setting it zero might lead to an off-by-one error somewhere - it probably won't, but I'm paranoid. Today I tested it in the car, and it worked. I did a full flash to get the OS blocks with the parameter change and the checksum change, and then was able to do two test writes with only a 1-second wait.

I wish I'd figured this out sooner, there's been days where I did 5-6 flashes working on my idle, and each of those is a whole minute of my life that I won't get back.

Nice one! https://xkcd.com/1205/

Oh no. I might not come out ahead on this one.

Ya think!

-Enjoy
