Hammered:
MS is working on a very sophistcated sequential system, even with ion sensing, but it's a ways off. MS is currently a batch system with two inj drivers that can be used either in an alternate or simultaneous mode. Sequential dosen't gain you anything, but slightly better very low rpm idle and slightly better emissions at low rpm. This is because at anything over idle the injector is open before, and as load increases, after the intake valve is closed. OEM uses this system for emission reasons only.
The new MegaSquirt II system features full ignition control and stepper motor idle air controllers (IAC), as well as having 12x12 tuning tables for fuel and ignition. Details? See link below:

I agree, wide band O2 is definately the way to go. I borrowed one for initial tuning and I'm saving my pennies for one of my own. This site in Australia has some good stuff.
