Used My HP Tuners For The First Time Today

I bought a used HP Tuners 2.24 kit off of e-Bay and used it for the first time today. I downloaded the latest software & drivers and installed them on my laptop, hooked up the benchtop tuning harness I built and did it on the kitchen table. Everything worked flawlessly. I performed a "Read Entire" on the VCM from the 2001 Silverado 5.3 engine I just bought, saved the file & made a copy of it to edit. I only edited the VATS, rear 02 sensors, and emissions for now just to get a feel for how the software worked. I Saved the file and did a "Write Calibration Only" back to the VCM with no problems. I then performed another "Read Entire" and all of my changes were there. I felt pretty good for my first try at it....

Here is a picture of the benchtop harness I built and the way it was setup as I tuned it.
