Blended Tables Questions

[R100RT]

Question for those who have ventured into blended Alpha N and S.D. tables, I'd like to run A.N. at low rpm's, and S.D. upper. I've seen recomendations for having it this way, and as well inverted the other way, with reference to lumpy cams, and turbo'd bikes - in my case it is a turbo'd bike and here is what I'd like to try:
Alpha N with its table configured for really low throttle positions like 3%/6%/9%/12%/18%25% and rpms at 800/1000/1200/1400/1800/2500 (seems the 6x6 table is all there is for A.N.), shift points set for around 1200rpm and 2500rpm, and the S.D. table starting at 1200rpm, and so on.
Not sure this is how it can be operated, using Micro Squirt @ V2.886 etc. The object is to phase out of A.N. rather quickly as rpms and loads increase, any comments welcomed. Been studying the archives and posts and haven't really been able to glean the answer that fashion.
Thanks, Lorne.

Hi, I don't know if you've seen this thread, and the bit that might help you is copied below.

In one blend mode if rpm is < Rpm1, you use SD, if above Rpm2 you use alphaN, if in between Rpm1 and Rpm2 you use a blend of the two. That means you calculate VE both ways and then weight the 2 results based on how far you are from Rpm1.
(If you were in the middle it would average the 2 numbers. )The other blend mode reverses this, so you use alphaN at low rpm and alphaN at high rpm. So the process can be made as smooth as you want by picking a large gap between Rpm1 and Rpm2.

Do not reverse the Rpms, there is a switch under one of the fuel menus - I thought in the same place as Rpm1 and Rpm2.

The internal auto mixture control should work in this mode, but I really wouldn't use it until you are able to tune it manually.

Just to add to this, it may be that the words describing whether alphaN is used at low or high rpms is wrong (reversed) in the ini file. If you find that that seems to be the case, just flip the option bit and ignore the wording.

Thanks guys, will check if the rpm is flipping on me, as what I felt should happen didn't at all when I tried running the two blends.
I have read that post earlier, probably will re-read it as I continue to absorb this blended alpha N/ SD approach, but the link is much appreciated.
I'm continuing to develop my speed density only table as an aside to seeking overal solid performance, and have found some improvements there since "twinning" my map hose feeds to both inlet tracts.
On that chapter I hope to have solved a lingering lean phase that waits on a significant decel to show up, to just when throttle is cracked open again - kind of confuses me by the length of time it hangs in there (and causing surging and bucking) till relenting back into a reasonable AFR, all the while VE bins holding firm, and other variables seeming to not be intransit. I know a frequent recomendation is to view the data logs, but I have not been able to glean the solution from that either. However, on my next road test I will increase the bins just below idle all along the rpm range in my table to see if that holds the key to the uber lean state. (perhaps a misleading aspect of that has been that extreme decel hasn't gone into lean but hung up around the 12's, just when you walk on it that it dives past 18 - probably a wild goose chase I haven't clued into properly) I suspect this is a similarity that many have faced during a new project?
If I don't get the results I'm seeking soon up here, I'll be parking the bike till next season and going at it again then (our winter rains and occasional snow don't justify having year round insurance, sigh - probably a couple of weeks of Indian summer now till she's all done.)
However, this winter will be a time to finish small fabrication details I couldn't anticipate, like suitable heat sheilding over the ceramic coatings, relocation of the M.S. ecu into a more ergonomic rear knick knack tray under my bikes seat that is totally weather proof, and creation of a hidden wiring harness that includes all the reset protective shielded cables that ended up as necessary to quiet function.

Can't complain, but do find the programing much more challenging than the fabrication and production was (and that is rather a strange twist) but equally, these systems are quite new and unique.
My objective, to repost as much useful feedback (once obtained) so as to help others moving through the process.
