Newbie to LS swaps

Hello and I’m excited to be here. I’m building a 1968 chevy K10 and plan on LS swapping it. I have all the important things like the truck and the drive train. I even have a donor for the LS equipment. My current issue is the pcm from the truck is a 9373372 I believe. And it doesn’t appear to have an XDF file for tuner pro. I’m wondering how I can go about changing the OS to one with an XDF file. Thanks and I appreciate any help that can be offered.

Hello,

What PCM? What engine and transmission?

What PCM info ru looking for exactly? And it’s the matching 5.3L and a 1968 gm 4 speed.

Is it a 512k byte P01 PCM or a 1 megabyte P59 PCM?
