Segment swap for DBC

[tweaker47]

Hopefully this is an easy question for someone to solve. I'm trying to piece together segments for a tune.

I'm starting with an '03 Caddy LQ9/4L60E/DBW 12576106 1mb pcm with 12593058 OS.

I would like to swap in the 4L80E and DBC engine segments. I have already found the 4L80E segments under the 12593058 OS but I can't find the DBC Engine segments. The 03 Express van does have DBC and the V8 but I can only find it under an older revision of the 12593058 OS (12579405)...

Question 1: Can I segment swap in the DBC Engine and Engine Diagnostic segements from the older revision of 12593058? I know the OS #'s dont match but curious if its still possible with a revision.

Question 2: Does anyone have an 03 Express Van tune with the 12593058 OS?

Thanks!

Well for future reference if anyone happens to find this thread in a search, I just used my J2534 tool and TIS2WEB ($55 for 2 days) to load the most recent calibration on my caddy PCM. I found a VIN off autotrader for a 03 3500 express van (DBC LQ4 and 4l80E) and just used that to get the base calibration. I dont need to segment swap anything now... 4 credits later I have a 3 bar OS on a 1mb pcm.
