I'm in the middle of creating a timing table spreadsheet for the 7747 $42, so that I can look at all the settings at a glance and see their effect on the overall timing. I've gotten the thing to the point that it seems to work, but I'd really appreciate it if any more experienced tuners could look it over just quick and see if I've gotten everything right - some of the behaviors of the different constants and tables are kind of odd, and I'm not sure of their behavior. The thing is too large to attach (and not a valid file extension), so I've put it up on my little site in a .zip.

You should (hopefully) be able to download it at

While I'm not very familiar with the calibration you are working with (i'm only somewhat familiar with $8d and that's it), it looks like you've done a really nice job with your spreadsheet!!

It took me a moment to realize that you had the temp/PE/knock stuff on one of the pages, but it looks like that should all work.

looks good to me.
