My idle is around the 50 MAP range @ 800 rpm (I like a little higher idle), so I was considering a change to the BLM boundries.
If a boundry or rather a block of cells defined by the boundries... If a "cell block" (for lack of a better term) contains cells in both the lower and upper VE tables, will this cause a problem.
E.g. boundries at 1000, 2000, 3000 rpm and 40, 60, 80 MAP. This devides the VE tables into nice sizes and puts my idle range into one cell block. But I'm worried that the range between 1000 to 2000 rpm has to work with both tables. Is that going to cause any problems?
Thanks

No takers on this question??? It must be either really hard to answer or a really lame question.
I'm not ashamed to admit that I don't know all this stuff so if it is lame just say so. I would rather ask a lame question than ASSUME.
In the 8D that I downloaded... It has one of the boundries at 1600 rpm which leads me to believe there may be a reason... since the lower VE table ends at 1600.
Is anyone running 8D with boundries that cross the break between lower and upper VE tables?
Thanks

I've been moving mine around to use the cells that are not in my combos range.
The stock RPM settings of 700, 1200, and 2000 did not seem to be good for me with an 850 RPM idle so I bumped them up to 1000, 1900, 2500 and the bottom cells now help with idle.
I think the span between 1K and 1900 gives me fits because my operating range is always above 2K when driving. My car doesn't like to go when not below 2K (Still may be a longstanding trans issue) but anyway I'll probably lower the 1900 to down to 1600 and then have the high one at 2200 for when I'm just cruising the highways. That will be my next testing session ideas.
As for the MAP side of things the stock 25, 50, and 80 have been upped to 40, 65 and 80.
My idle is at 55 Kpa so it help to gain the separation between overrun, idle and off idle cells. I may bump the top to 90 and see how that works too.
Still not conclusive evidence that the numbers I used will remain as they are but they did help move the operating range around.
Have to watch how you do it because at one RPM/load combo the correction is not consistent with later hits in the cell and the correction keeps changing.
Basically, Need to find a happy medium for the settings to coexist with your setup. Just my experience with it so far.
HTH.
