You'll see this unit in our trailer. We use it. You have to in order to track performance changes in the air.
This All-in-one digital portable weather station includes all of the great features of the original RaceAir with the new programs for dial-in, throttle stop, run completer (very important tool), carb and fuel injection jetting, chassis setup, test and tune, and an internal fan for more accurate readings.
Digital sensors provide consistent air readings for exceptional dial-in prediction. We suggest you keep it in a cool dry place away from wind and heat sources. Look at it prior to each run and after each run and map the density in your logbook. You'll be surprised at how much you learn from this unit and how important it is to your program.
