Jim, just saw a PM reading "go look at this thread." Just hadn't noticed it. I've done the TM install on my bike and one other now. Only through the basic setup procedured on both and a bit more tinkering on mine after the fact. But not a lot.
May not be able to offer a lot of insight or support but glad to help if I can. So if there's a question still unanswered offer it up again. Will either dazzle with brilliance or make up some chit involving martians and left handed spanners.
Thanks 2L! Go ahead and dazzle me with your brilliance regarding Martians and left handed spanners then! :-) Hope you've read right through the thread, because the guys have come up with a few beverage-spew posts that are worth reading!

Here are the unanswered questions:
Well, in the absence of any other suggestions except Jacques', I went with map 377.
Went very easily after that, uploaded the base map, and let it do the IAC, and that was that.
Would someone who's done this be kind enough to answer a couple of simple questions?
1) After the IAC has been autocorrected, the instructions tell you to manually align the blocks before and after the autocorrected ones, to make them a straight line to the first, and after the last, autocorrected blocks. Mine seemed fine already, not needing touched (although that screen, and hence the dots, is
very small so it's hard to tell!) - is that normal, and acceptable?
2) I assume that's it, and (having checked that it's all set to closed loop) I just ride and let it tune? If map 377 was far enough off though, I assume that it will take a few miles to get things right, because of the 5% (session) learning, but the 20% (max) learning will get it there in the end?
Jim
