Mine is scaled from 1600 to 7000 rpm. 20kpa - 230kpa.

16 on the lowest line, 15 in cruise sells, 13 at 100KPA 12 at 230KPA.

Fill in the blanks evenly.

These are pretty arbitrary, but they seem to work well:

lol. Motor likes fuel. Boosted cells stay rich till I get a new fuel pump and get spark dialed in. For safety, not optimal HP.

Might have to post mine, I'm sure it'll be the leanest of the bunch. :-) Works well though.

Thanks guys.

I had an idea of what it was supossed to look like, I got the AFR thing figured out (little different than what was posted) so I'm going to try a few different combinations and see what happens.

I was pretty convinced this helped my fuel economy a TON over the old settings... but it turned out just to be the freeway miles. Still a bit better, I'd say 20-22 in town, 25-27 freeway. It used to be quite a bit leaner off boost.

Yes. MS1 has 8x8 AFR tables, MS2 has 12x12.

The value of larger tables than this would be debatable, as you don't generally want sharp transitions in AFR.
