Any one use the msd 7 or 8?

So this is my limited understanding of how it works.

The CPU reads data at 100 time per second. If the engine RPM spikes it will pull timing and reduce power.
That is per the MSD tech guy who says all the advanced timing functions will work with my MSD pro billet distributor.

I think what needs doing is you make a good pass and adjust the box?

It dose not require any wheel speed. Its what they call "slew timing"?

The MAP sensor will be attached to my 6-71 for boost retard. The crank trigger and cam position sensor are not required but will make tuning easier while providing a more stable ignition event.

Not sure if the box will i interface with my wide band but that would be slick.

From the little bit of reading i have done the box will provide more than i should ever need as a "street car".
