So my next question, and this may be different between 930 and 965; does the frequency valve adjust fueling for part throttle accel if you're running open-loop? My understanding of the system is that the part-throttle accel enrichment is commanded by the O2 Unit briefly pulsing the frequency valve at 75%. Does anything else control or modulate the frequency valve if you're "unplugged"?
