on track, FAST.

BTW, I did not use valves jets, but normal ones. Still good you got the check valves ones.
That saves the effort of compensating any initial delay.

The initial period was covered by extending the acceleration fueling duration for a fraction of a second. The AFR data logs allowed to see this tiny delay as did the knock gauge of the knock control system. With the right settings, no knock was detected independent on how fast you depressed the throttle. I used the WI extensively on track.
