A/F readout delay

On the racepak, how much delay from the RPM readout is the Air Fuel readout?

Marty,
On my Holley system it seems to be .4 second.

Thanks Bob! I was expecting something like that How did you determine that amount of delay?

About .2 of a second on the racepak. I look at engine rpm and my shift point vs biggest fluctuation of O2.

My delay is .2 second also. Each step on the graph is .5, not 1.0. I figured wrong.
