May 4, 15 - New feature

Earlier this year we added a new feature to the pro-calc section of the site. There is now an option for a pump saver or 2nd high speed bypass. We have been testing it over the last couple of months and it is working great!

If you'd like to give the pro-calc section a try, we offer a free 30 day trial.


Jan 16, 15 - A Question for Australian Users

The bulk of the tracks featured on this site are for US tracks and, therefore, use imperial measurements and fahrenheit temperatures. Would users outside the US get more use out of this site if there was an option to convert data into metric and centrigrade units?

If you have thoughts on this, please contact us. We appreciate your feedback!
