I fully agree with you that it is better to solve problems than just disabling codes.
However, if you read up on "tuning for a stall", you will see that disabling codes is a common practice.
BTW - Congrats on getting HP Tuners. I get tremendous enjoyment out of tuning and change something nearly every day; I constantly log with my laptop. (Of course, I been an electronics/computer nerd since age 6, 52 years ago.)
Hopefully we can help you solve your trans problem.

True true, in my never ending search of what these symptoms mean I have come across deleting that a lot.
Thanks! I've been wanting to get a copy for years. I figure I've done all the work on this car myself besides, the trans rebuild, I should be able to figure out how to tune and do diagnostics. I'm an electrical engineer by trade and a programmer so hopefully that will help out some. from what I am seeing the next thing I need for that though is to get a quality wideband setup.

Nice, I've been doing a bit of research on those. I'm not sure which one will work best for me. Where did you mount yours in the exhaust? I haven't really found anything conclusive on where is the proper location to mount a wideband.
I also found some threads detailing a way to use the old egr wires into the pcm as a way to data log with HPTuners std which will be really nice.

I have headers and mounted the O2 sensors in my collector after the headers. The must be at least 10 degrees up from horizontal. You might have to adjust the position and angle according to where you have room. This picture shows where I mounted:
I have a stock O2 sensor on one side and the AEM wideband on the other side. You can even set the AEM system to "simulate" a stock narrow band, but then cannot log the wideband values. When convenient I will install another stock one near my wideband in case I ever want to try going closed-loop.

Is it effective to tune using the wide band only on one bank though? Or is the merge just too far down stream to get good readings without introducing too much latency?

The LS PCM don't let you tune individual banks (and certainly not individual cylinders), so I assume that checking one bank is enough. I also log the narrow band and when my wide-band is in range, the other bank's narrow band pretty much agrees.
I would try to avoid latency as it confuses interpretation of the logs.
