I don't fully understand why twin spark maps are important/a benefit when in SD. Can anyone shed some light? How are these set up properly?

Without the custom os when you unplug the maf the PCM uses the Low octane table for spark. Most of us SD guys running 1 bar have copied the hihg octane table to the low cotane table. This takes away our protection from Knock and bad gass. The twin spark maps allow you to maintain high and low octane functionality in the absence of the MAF sensor
That makes sense, when I used to tune with edit, I always just copied the high to the low and called it good. I guess it is probably smart to use both tables now!
