Success. Tested it today and it was right on. Here's what I did. Change the BCM module (726-45-01) as per the spreadsheet and calculator. Next I had to run the initialize PCM module. Just go into the PCM module and there is a line for reinitialization. It took me a while to find this. I went thru the Forscan tweaks and then went to forscan.org forums to find anything I could about speedometer. Then I found out about the initialization. I couldn't find any detail about it, so I just went into the module and there it was. By the way, the calculator was right on. Hope this helps other newbies. I'm done with the two things I wanted to change. I'll have to scan the files again to see if there is anything else that looks interesting.
