Calculations

Speed-Wiz has calculations in the areas of general, conditions, fuels, engine calculations, engine simulation, fuel injection, turbochargers, chassis, aerodynamics, electrical, suspension, steering, brakes, tires, performance, reference, costs, maintenance, and race strategy. It calculates hundreds of different values. It also has graphs for the same areas. In addition are unit conversions, performance optimizations, a lap timer, and some fun stuff too.

User Interface

The user interface has many features to maximize your productivity and enjoyment. Point at an item and a tool tips tells you what it does. Shortcut calculation links let you quickly calculate data inputs. Range tips for all inputs in all calculation windows. Mix calculations, graphs, reports, and help on the screen any way you want. There's a docking/floating tool bar and a status bar with detailed menu hints, status indicators, and a measure control.


Speed-Wiz has full-size calculation windows with a row of tabs along the top that allow you to view and select windows. Here you see Strategy, A-arm travel, Viewer, Compressor map, Help, and Convert windows are open, with the compressor map visible.

You can also use the MDI mode with windows that you can cascade and tile.

In the tabbed mode, you can create side-by-side groups of tabs. This allows you to view calculation windows simultaneously while still enjoying the benefits of the tabbed window system. Here we have a data log viewer on the left and an acceleration plot on the right.

Speed-Wiz offers skins to allow you to instantly change the entire look of the application to a scheme of your choice.
