Something to consider;

I have been playing with using secondary table (or table switching, both do the same thing bus through different mechanisms) with speed density effectively creating a VE table with 16x32 bins of resolution.

My primary table goes from 35 kpa to 80kpa and my secondary table from 80-101kpa.

The amount of resolution this affords means that I can have individual rows for 85-101kpa giving me all the control I want and need. With my engine basically everything happens from about 84-100kpa and being able to precisely control the fueling for each step in kpa has meant that I don’t need to use ITB mode or Alpha-N.

Just food for thought.
