Newb needs help with ram dump

[G-Body]

I was trying to use the Ram dump feature to locate some of the inputs on a P59 PCM. (I wanted to swap the input for the A/C request and the extended brake travel switch, among other things). I assumed that If I dumped the ram then put voltage to the input I would be able to see where that input was stored in the PCM. When I try doing back to back ram dumps there is a significant amount of ram that is different, it was 620 bytes different. I didn`t really expect there to be that much difference in the ram dump when I did it back to back, am I getting bad data or does the ram change that much within a few seconds with no changes to the inputs in the PCM?

It changes that much. All of the runtime state is there, all of the analog reads, any timers or counters etc. Especially the analog world is noisy and imperfect so sensor values, will have change, and then anything the pcm is calculating from those values and storing will change. You'll need to repeat your test a few times, and then maybe write a quick app to look at the bins and look for the value that is always higher or lower following your change to the input and that should rule out most of them and hopefully only what you want will get through the filter.

What OS i have ram info for P01 and P59 controllers

I realize this is an old message but if you have information about which RAM addresses hold which values for 12587603, I'd love to see it.
