limiter cut sequence?

Any of the stock ecu gurus know the cut sequence of the stock ECU for the limiter and 2-step?

What I'm looking for is on each cycle or revolution, how many and which cylinders are cut? anyone know?

All cylinders are fuel-cut simultaneously.

Yes I would think it starts with whatever cyl is about to be fired and go on from there

I know with the standalones anyways, (also running ignition cut) you can set things to keep the engine spinning at the set rpm.. so you can fire a cylinder or two each revolution to keep it spinning and build boost.. if you cut the fuel to all of them at the same time, it would make me think the engine would just stop turning..

or do you mean the stock ecu cuts everything at the limiter rpm, then restarts at say, 150rpm less then comes back up to the limiter and cuts fuel to everything again....
