Seeking a stock compatible compare file please and thank you

Greetings old (and new) friends. I am SO delighted to be back after so very long. I woke up to the first beautiful and heavy snow this morning at our new location. Back on topic:

I am seeking a stock compatible compare file please and thank you. Just took over sorting a co-worker / supervisor's personal truck and there are some very basic and minor changes I need to make to it. But first I'd like to see how this current mystery file differs from stock. It starts / idles / drives - just not very well. We've gone over mechanicals and I'm ready to fix idle, takeoff and shifting hiccups. This will be a great way for me to jump back in and get in the boss' good graces at my new job too haha. Thanks and I hope all are doing outstanding, best wishes for '25 !!!!
:cheers:

(please see files attached)

ECM Operating System 12630501

Dunno what engine your working with but here is a 12630501 OS for a LC9 and L92.

Car and truck TCM tunes with OS 24249179

Couple more i found

Thank you! It's a 5.3 essentially I just need a compare to see the mods to the cal. I think you can only compare same OS, am I correct? I could always do it manually. And for the record it does NOT have a good or locked tune in it. I can do way way better, just haven't done this in a decade LOL! Thanks for the replies and the help !!!

With V8 you can compare anything you want. It doesnt have to be the same OS.

Glad to help!
Your file is from a newer version of V8 so i cant open it on what i have.

So I need a compare file of a USA based 5.3 liter "3" motor (8th digit) with a 6 speed transmission (T43). All I'm finding online so far are Australian "Y" motors.

RPO code "LC9"

Looks great, thanks much! Even though it's a 2011 to a 2009 and thus newer calibration version, I am sure the hardware is the same. I was successfully able to compare both sets of files which was the goal. Awesome, now I just need to figure out which differences are manufacturer updates and vehicle differences, and which are actually aftermarket tuning modifications. Good deal, I appreciate it!
