I'm glad I could contribute and hopefully it will earn me some help when it comes time to tune my 6.0 ls3 topend in a few years when I'm ready.

Quick fix to AC Minimum Off Time should be 0x1F890 instead of 0x1F891
Also "PID Jump Table" and "Supported physical OBD message modes" should be in Hex digits

In this 7603 XDF I see the RPM Drop Ratio table. From what I can find and understand, it controls reported shift time or it is the main timing mechanism for the entire shift after the initial shift command is sent. It seems to help control shift performance particularly when a higher stall converter is used. What I do not see are the shift torque management ramp in/out tables. Referencing the dumpster dive .csv from NSFW's github the tables start at 1C314. Has anyone looked at these? Based on the descriptions I presume one of the axis's is the actual shifts 1-2, 2-3, 3-4, but I do not know what the other axis would be. My guesses are normal/perf/hot, shift torque(meaning delivered torque recorded at the start of the shift, per available patent info), TPS, or trans temp.
Also curious if anyone has defined the thresholds for adapts and torque management. Referencing the dumpster dive .csv again, it looks like there are min/max parameters based on torque.
Very green to all this but just wanted to bring those tables up for discussion and see if anyone has tried to mess with them.

Thank you Bubba. I've fixed and uploaded the new file.

Anyone run a Camaro with a 7603?

You would have to swap the PCM to a P59.

I think I found some errors in the Transmission Calibration->Cruise section. The min and max values seem to be reversed on a lot of the parameters. Max is 0 and min is 65536. Whenever you edit the value it automatically jumps it to 511.

I think the version below should have that corrected.
EDIT 8/31/22: Added most up to date XDF version.
