I'm looking at the whole multi Spark section of the ECM.

Is it safe to turn this on. Do we have tune from one of these ECM's that have multi spark enabled from the factory?

This is from a 2015 Z71.

Can provide Tune file.

I think (can't back this up) it was only for E85 in cold weather.

Hum.... I have a MSD Digital 6 on one of my trucks and I love it. Made a huge difference.

Was hoping this could be enabled safely.

I've seen this table and wondered the same thing.
What I would "assume" is that it would help at low RPM (similar to an MSD setup). Maybe with a cam? To help with idle.

I have not turned this on to see what it does. I'll have to mess with it the next cam'd LT1 I tune.
