"(the VEC1 capability)...by giving you the ability to adjust fuel and timing
curves for different load conditions or engine modifications. "
That's totally possible on our systems and I have already experienced
several situations like this by playing around with the check valves during
the preliminary stages of the "MAP/Boost Bypass System".

Lets be clear on this - it does NOT change the A/F Ratio! What it changes
is
the signal that the PCM is getting from the MAP sensor. Nothing is changing
the signal from the oxygen sensor. It is still a 14.7 to 1 oxygen sensor.
The
PCMs main strategy (closed loop) is to hover around 14.7 to 1 Air/Fuel
ratio.
It will do this with or without the VEC1 being hooked up. I would love
someone
to be able to prove otherwise but only the high-doller aftermarket EFI
vendors
can actually allow you to dial in say a 12.5 to 1 A/F ratio and run around
in
closed-loop around 12.5 to 1 (best power).
