You were able to change from 7000 to 5500 so you should be able to start your first row at 500 if you want and adjust the others accordingly. At least that's the way MS1 tables work. I can enter any rpm I want in the RPM row.

You're right I probably won't see much action North of 5000 rpms unless I get some bigger valves. Will try a little more advance around 2000 as well. Thanks.

I have a cranking advance set at 400 rpm and 9 degrees advance.

Next is an idle advance of 700 rpm at 12-15 degrees

My 3rd line is 1200 rpm but my advance is all fubar-ed at the moment due to problems with the new engine.

Once you get over 3000 rpm your advance won't change much so you can go at 1000 or more rpm jumps.

Tune the idle to 3000 rpm with as many lines as possible.

Try something like...

400 700 1200 1500 1800 2100 2500 3000 4000 5500

Then fill in your advance settings.

Every change just do a save-as to name it something for the new tune. You can then go back to an old tune if something doesn't work out right.
