Thanks

The 3D map is created very simply (for the end user) by setting start and
full points according to EFI PW and Boost. So, 4 points, and the software
creates a 3D map from that.
Once the map is created, the end user can change the importance of the input
signals (EFI PW and Boost) from a 50/50 level to anything between 100/0 to
0/100, tweaking the map dramatically, but very quickly and easily.
The end user determines when the "Power mode" injection point starts vs. the
MPG mode nozzle, according to either boost or EFI pulse width. Basically,
you can set it up to have 2 injection curves: one for the smaller nozzle and
lighter loads, and one with both nozzles - and we are not just opening a
solenoid and continuing to increase pressure for the second nozzle, we are
modulating pump output so the flow delivery curve is very smooth when
kicking in the "power" nozzle.
Again - the standard stage 3 doesn't have an mpg mode vs. the power mode, it
only has one mode of injection. The MPG MAX adds injection capability in
lighter load states to help with fuel economy.
