DataZones can be displayed in any color(s), and you can automatically select a gradient range between beginning and ending colors.

Graph Reticle Synchronized With Vehicle/Data: Selected ProRacing Simulations have moveable reticle lines on graphs that is synchronized with underlying data. By moving the reticle over the graph, the corresponding data or vehicle movement will be displayed. This feature is very helpful in analyzing complex vehicle telemetry or engine performance data at any point during the simulation.

High-Resolution Testing: A ProTools™ feature in FastLapSim that includes additional mathematical routines that perform a more in-depth analysis of every corner, braking point, all suspension movement and forces applied to the test vehicle. This calculation-intensive analysis, when activated by the user, predicts lap times and vehicle performance data with high accuracy (additional calc time is required). If you need the highest accuracy possible, High-Resolution Testing will help you achieve your goals.

Iterative Spring/Damper Testing™: This powerful FastLapSim ProTool™ will help you select the most appropriate shock absorber for any spring rate. The Iterator tests dampers with the current spring, performing a spring/shock dyno simulation and selecting a combination that effectively dampens the spring (without overdamping). Iterative Spring/Damper testing is an indispensable tool for zeroing-in on the best shock combinations.

Multi-Page Test Reports: Simulation analysis is printed in color on several pages, depending on the simulation package. Component selections, custom data (like cylinder head flow, power curves, etc.), graphic analysis, and data tables comprise some of the pages. For even more-enhanced printing, see ProPrinting.™

On-Graph Comparisons: Compare any four "open" simulations (see Test Multiple Engines/Vehicles) on any of the graphic displays. Comparisons can consist of any of the displayable simulation variables, like horsepower, torque, engine pressures, vehicle speed, engine rpm, acceleration (longitudinal and lateral), and much more.

One-Click Iterative Testing™: Iterative™ testing, an exclusive feature of ProRacing Sim software, is an automated method of performing multiple tests and locating optimum component combinations. One-Click Iterative Testing is a feature of the QuickIterator™ incorporated in several ProRacingSim simulations. By simply clicking a single button, the simulation will begin a series of tests and display the best result, all without user intervention (also see ProIterator™).

One-Click Quick-Compare™: A time-saving feature that allows you to instantly establish a baseline engine and perform a side-by-side comparison with a single mouse click. This is the fastest way to test component changes and view how they alter engine or vehicle performance.

Optimized High-Speed Simulation: Simulation code written in C++ for super-fast execution. Substantially shortens data analysis during Iterative™ testing.

PopUp Time Slip™ and PopUp LapTime Slip™: These "Pop-Up" or floating data windows provide an easy-to-read overview of the performance statistics for the currently simulated vehicle. They can be thought of as the electronic counterpart to the paper "time slip" presented to the driver after a race. They show the basic, essential performance data to determine vehicle performance, such as overall elapsed time, current weather conditions, driving style, and user selections.

ProData™ Graphic Displays And Tables: This is a professional feature available in the ProTools kit for many simulations. Includes the calculation and display of additional simulation data, often needed by professional racers and/or engine developers. The ProData Tables display extensive additional data in an easy-to-read format, and are available in addition to the standard graphs and data tables provided in the simulation.

ProIterator™: Iterative™ testing, an exclusive feature of ProRacing Sim software, is an automated method of performing multiple tests and locating optimum component combinations. The ProIterator, a ProTool feature, provides maximum flexibility in selecting components and setting up the desired testing criterion. Search for optimum power/torque/acceleration, or locate the component combination that produces maximum "area-under-the-curve" for horsepower, torque, acceleration, or other variables. Once you have established the testing criterion, the ProIterator will begin a series of tests and display the best 10 results, all without user intervention (also see One-Click Iterative Testing™).

ProPrinting™: This is a professional feature available in the ProTools kit for many simulations (exclusive feature of ProRacing Sim). ProPrinting produces custom, full-color, multi-page test reports, including cover pages, tables of contents, your name and/or company name and logo, and even an optional glossary. ProPrinting produces an easy-to-read, comprehensive, professional printed test reports that you will be proud to display, present to customers, or keep for a lifetime.

Real-Time Results Displays: Most ProRacing Sims are designed to show the components on the left and the results on the right of the main program screen. This allows you to inspect all the components that comprise the simulation, easily modify any components, and instantly see the results in graphs or tables. This exclusive design sets the standard for "What If" testing.

Real-Time Simulation Dialog: A unique feature in the Advanced and ProTools versions of FastLapSim. Allows you to view the simulation process realtime, observe an extensive data display, watch the simulation zero-in on the best braking points and corner speeds, see suspension movement, G-forces, and more!

SimData™ Window: This is a "Pop-Up" or floating data window that provides a detailed look at the "telemetry" for the vehicle (or engine) throughout the testlap (or dyno run). The data displayed in the SimData window is synchronized to the position of a moveable reticle line on the data graphs (see Graph Reticle). This display, along with graph reticles, makes it much easier to analyze complex vehicle telemetry or engine performance data at any point during the simulation.

Test Multiple Engines/Vehicles: A powerful feature that allows testing multiple engines or vehicles at once. Each "open" simulation is available for analysis, and can be brought into focus by simply clicking a tab located at the bottom of the screen. This professional feature saves time, eliminates opening-and-closing multiple simulation files, and permits rapid side-by-side comparisons.

Track-Segment Data Analysis: A ProTool available in FastLapSim that defines portions of the track as "segments." Segments can be used to analyze vehicle entrance and exit speeds, average speeds, and other vehicle "acquisition" data. Unique colors can be applied to each segment, making visual identification easier. Up to 30 segments can be defined for each track.

U.S./Metric Units: Allows rapid display of either U.S. or Metric units. Switching between units system is seamless and instantaneous.
