Not at WOT. The O2 sensor isn't used at WOT and a fixed table is
used for the frequency valve - 68% at high RPM. Current wisdom is
to set the duty cycle around 40% at idle, so this already gives
extra fuel at high boost and RPM... sounds like we need to do some
measurements of fuel delivered vs sensor plate position and frequency
valve duty cycle.
