They work fine. The download kit is nice, just wish the cable was longer ( you can get a longer one just not from them ).

PerformAIRE weather stations are the only patented system that has a Density Altitude calculation specific for determining horse power in an internal combustion engine. It is critical to measure the amount of oxygen and the amount of water in a sample of air in order to determine correctly how it will effect the change in horsepower.

Systems that are designed for hiking, aviation, sailing, etc that are not licensed by Altronics can only calculate "text book" Density that will not always correctly relate to horsepower changes. Although it may seem ok under minimal or similar changes in atmosphere it will prove inaccurate as conditions change.

We win or lose now days by +/-0.01 seconds or less!!

How do you measure Oxygen do you have a sensor? I have used a Oxygen Meter since 1985. % of oxygen has a big affect on performance! a change from 19.8% to 19.5 is big!
