stalling issues
Correct me if I am wrong, but adding more advance in the 0-1000 RPM and 10-40 LOAD range will cause the idle to be a bit more "lopey" or "rough". From what I have read in the MIVEC TUNING thread and others you want to keep those values as close to 0 in order to keep a nice smooth idle - in that range at least.
Desired ISCV intial step position & Desired Idle rpm. Maybe a timing adjustment if needed.
Also driving style matters a lot too. Dont push the clutch in a 5K and just let the RPMs drop all that way. It will almost always stall when doing that, regardless of settings.

May I ask what timing adjustments you would recommend in the 0-40 load and 0-1000RPM BLOCK range? Would anything lower than 10* be too low, I am currently running 8 degrees in those high octane maps.
I understand that and I agree. I am just wondering if you need to add some additional timing/fuel in those load ranges also.
I've found that just the opposite is needed for smoother idle on MIVEC engines. You DO NOT want MIVEC messing with idle. When we rescale the rpm and loads it causes the MIVEC table to affect areas it normally wouldn't in stock form. Simply making the appropriate changes to the MIVEC table to not affect timing areas will greatly enhance your idle characteristics.
This was the better of the 2 explanations you gave, easy and concise. Any thoughts on my ranges above would be appreciated! Thank you for your help.

Looks like it should work out just fine. You can add a little more timing to smooth the idle out a little (make it not so lopey)
thanks for your timing trick it seemed a help a lot with the recovery however with that it would still stall especially when pushing the clutc in at 5K. Only after i changed mivec did the stalling stop entirely
