1)  New Produce Released, Weather Wiz v1.1   We've released a new program, our Weather Wiz.  It lets you do all those weather calculations, and make jet predictions.

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.

At this time, we've got nothing for you to read.  By next newsletter, this major update should be released.
