Hi, I'm just getting into ls droid and looking to learn about tuning for ls swaps. Any and all help is appreciated. Thanks

Ok so I got everything in order. I hope. But I cant seem to find a xdf file that will work with what I have. My pcm type is po1, and the numbers I get from ls droid are pcm os 9373372. Ok with that outa the way. All the videos I've seen they get a os # with 8 digits I only have 7. Am I missing something? 1999 gmc 5.3

Digging this back up because I am in the same situation as the OP. I have a 03 LM7 DBW I am using for a swap. At the moment I only need to do the basics to the PCM to get it in the car. I have connected to PCM hammer and got the serial number and OS from it. I have not been able to locate a XDF for the OS#. How do I change the OS to a more common one with an XDF available?
