The PMW control had done distinct advantages depending on how it is configured. Basically, you can reduce the duty cycle at low fuel demand periods. This of course allows for a pump that is not driven as hard and cooler fuel. Also, you could possibly use different pressures to allow for a longer injector duty cycle at idle and raise the pressure at WOT to reduce duty cycle for high rpm.
So, basically, the fuel pressure becomes part of the tune. Now I really expect all this is to facilitate a dead headed fuel system for this efi system.
The O2 sensor is a handy tuning tool. Every engine seems to like something different, but at least you have a bench mark to tune from. Check out 14point7.com. I use a setup from them for my megasquirt.
And speaking of megasquirt, even a cheap ms box can data log and with a wireless bluetooth adapter, can send logs out to a virtual dash with any gauges you want to a smartphone or tablet. Heck, you could even stick with a carb and gain ignition timing control. Lots of possibilities. I am sure other systems can perform in a similar fashion, just not sure of the cost.

Reason: Pump is not spelled P-I-M-P!
