One thing I've noticed this week using CrewChief as my spotter is the threewide calls. With the iRacing spotter, the spotter will immediately tell you when you are going from two wide to three wide or three wide to two wide. CrewChief will only seem to update you at the interval that you have set in the settings.
It is really important to know immediately whether you are three wide or two wide. Is it possible to update CrewChief so that it immediately tells you when you go from two wide to three wide or three wide to two wide? The same way it tells you when you are clear immediately.
