Computer Program to make Weather Calculations which affect Engine, Carburetor Fuel Metering and Vehicle Performance for Drag Racing, Circle Track Racing, Road Racing, Dyno Tuning, and Street Tuning
Our new Weather Wiz lets you easily make all those weather related calculations like Density Altitude, Relative Air Density, Dyno Correction Factor and more. It lets you specify the inputs you want to use for entering barometric pressure, humidity and air temperature. It also "talks" to our Weather Station for instant updates of critical data.
Unlike most programs, you don't have to use the same types of inputs for the comparison. For example, your baseline condition may use a barometer instrument, and your comparison may use an altimeter. Or your baseline condition may use wet and dry bulb temperature for humidity, but a dew point reading for your comparison conditions.
It also lets you specify the air temperature at the engine (which is the critical temperature) different than where the humidity was measured. For example, your relative humidity instrument (or wet and dry bulb instrument) may be in your trailer or dyno control room. However, the air going to the engine may be considerably warmer. This definitely has an effect on engine performance and carb jetting.
Options for Reading Weather Station
|Can read our DataMite "Stand Alone" Weather Station (see picture above of screen options and picture below for actual hardware). It measure Barometric Pressure, Air Temperature, and Humidity and has a recirculating fan for fast response to weather changes. It needs only a USB cable for communications and power, and Weather Wiz software to read it. 4.25 x 3.00 x 1.38 inches (108 x 76 x 35 mm)|

|Save, save as (to a new name), delete, and open your sets of conditions to either the Baseline Side or Comparison Side of the screen.|
|Copy conditions from one side to the other, or swap conditions with one click buttons.|
|Print your results.|
|Lets you do side by side comparison of all jets for your carb(s), 2 barrel, 4 barrel, three 2 barrels, two 4 barrels, etc.|
|Lets you correct for the size power valve you are running, or perhaps there is no power valve restrictor.|
|See how much richer or leaner your engine will run with out rejetting, or see what the Weather Wiz would recommend for rejetting.|
|Lets you copy weather readings from our DataMite data logger software for doing additional weather analysis, like jet recommendations.|
