TEST EXAMPLE 1 - FIGURE 6
This test shows near optimum PID values, with some improvement still possible. The TargetPsi was
programmed for 14psi boost and was able to reach this value and regulate within about +/-1/2psi
of the target pressure. Note this was at very low RPM of about 3,600 rpm. As rpm increases the
turbo becomes much more efficient and easier to control. The PWM values stayed out of saturation
(40-159) range, but since the rising edge of the boost pressure was little below target, the D term
could be reduced slightly.
