How to make 01 5.7l vortec 0411 pcm to run 5.7 ls1

They go by many names, P01, P59, VPW, '0411 etc. Also covering E38 and newer here.

We thank ya sir!

So, does that involve removing just the OS xdfchecksum node,

Code: Select all

  <XDFCHECKSUM uniqueid="0x47C4">
    <title>1 - Operating System Checksum</title>
    <REGION>
      <pluginmoduleid>9a53f579-d1c9-40c6-8691-7a54fa789d3b</pluginmoduleid>
      <datastart>0x0</datastart>
      <dataend>0x7FFFD</dataend>
      <datasizebits>0x10</datasizebits>
      <storeaddress>0x500</storeaddress>
      <calculationmethod>0x0</calculationmethod>
    </REGION>
  </XDFCHECKSUM>
and that makes it not do the checksum for the OS which is not needed, because no code changes were done ...

That is correct, provided the other segments use the built in tunerpro algorithms (tunerpro default checksum plugin, twos compliment), which the XDFs I've seen do. They could use the same plugin as the OS segment and get the right result, but then you'd need the plugin for artificial reasons. If they do have a 3rd party plugin, setting it up as i've described and not changing the addresses will remove the dependency. The plugin is needed for the OS because tunerpro cant handle a non-contiguous segment like the OS segment natively. Calibration segments are contiguous and so are fine.

Sweet, Thank ya!

Gotcha on the each <xdfchecksum> node could have it's own <pluginmoduleid> node ...

I got a copy of an 01 camaro bin from a friends car that was stock. It's a different os but even with the right xdf it's doing the same. So I tested a 059 pcm by just deleting vats and saving it. Its does the same thing there too.

So the plugin should fix this ?

I really appreciate the help with this all.

Either install the plugin, or edit the xdf header in tunerpro and remove the operating system checksum.

Pcmhammer wont flash a file with a bad checksum, so there is a layer of validation there.

I wish we did have a better archive for XDFs but this is what I would use for 12212156. It does not require a plugin.

Thank you Antus. This worked great.

My issue ended up being TunerPro itself. I had to uninstall it and then reinstall to get it to work correctly.
