Well I followed your directions for 'engine' and B and C I got nothing. Will double check. Also checked for 'trans' on the square plug, and B and D got the same outcome as B and C

Ok, so with the digital unit it helped a lot. My input I'm getting 4.85. Output, was .17. Max I can get adjusting is .71. 17% per your instructions is .8245.

After seeing this post, I went out and adjusted mine on my 90 xj.
Did it the way the video suggests, no difference. so I pulled it out one click to loosen it a bit, it was actually keeping me from getting FULL throttle by small amount.
took it for a test drive, made a hell of a difference. probably the opposite result that you want but it raised my shift points a bit, it feels more normal. But I also have oversized tires. the motor doesn't feel as overworked anymore.
plus before I had to let off a bit for it to shift sometimes, now it just shifts. even at WOT.

Well, the adjustment to the TPS didn't effect the shifting. I picked a new one up from AZ, but not sure if I should go ahead and install, or look elsewhere for answers
