Beyond Super 8d bins ??

Are there any available bin files/and or hacks that allow even more flexibility using the Super 8d in a 727/730 ecm ?
Currently my tune is fine and can't complain (128/127-129 int. and pretty much 128/128 under 1600) and have spent much time developing all areas of the tune including AE, MATvs MAT, WOT, etc. etc.
However, as all who have worked these bins knows that there are areas that fall between the "cracks", both in ve tables and timing. Is there, or are there any bins available that split the upper ve in 100 rpm increments (or least better than 400 rpm), as well as the upper MAP kpa (split like the lower ve table)?
Additionally, are there any timing tables w/greater flexibility,that would allow adjustability every 100 rpm instead of the 200 rpm currently in the tables ? TIA, M7

Re: Beyond S28d bins ??

It depends on the engine. All that I have played with are OK with the stock resolution. Some needed more dynamic range.

What kind of engine do you have that would benefit from more resolution?

Re: Beyond S28d bins ??

the current is a 355 (mods in sig.) ,
I understand, and I have made it work very well, however, there are areas in which one needs to be creative w/a combination of timing and fuel to achieve the those results.
On my new build (434ci.) I would like to have more room in the upper tables (IE. 35, 45, 55, MAP kpa), and the timing table above 1600 rpm to include more scaling instead of every 400 rpm.

So no-one has added additional hacks or reworked the $8d ???
