X-Weight is a cross-weight calculator for 4-wheeled vehicles. I wrote it during my kart racing days to help with properly setting up weigh distribution. It is a fairly simple program where you enter the measured weight at each of the four wheels and it calculates each all of the relevant (Front/Rear, Left/Right, Diagonal, etc...) sums and percentages.
X-Weight will also maintain 4 separate measurements, on different pages, so you can easily switch back and forth to compare different measurements. Having 4 pages also allows you to test what-if scenarios with different wheel weights.
For more information on setting up corner weights, here is a good article from Grassroots Motorsports magazine: http://www.grmotorsports.com/news/012005/understanding-corner-weights.php
The source code for X-Weight is also available on request. Just send me an email and I will send the source to you.
Please send feedback if you successfully ran X-Weight on Palm OS 5.x
