Wintax 4 User Manual Guide

WinTAX4 is a professional motorsport data analysis platform developed by Magneti Marelli. This guide summarizes the essential steps for installing, configuring, and using the software based on official documentation from Racing Tech and Peugeot Sport/Citroën Racing guidelines. 1. Installation and Activation

To use the 4.23 or 4.80 versions, follow these steps to secure a license and install:

System Compatibility: Run WinTAX4 in Windows 7 Compatibility Mode and as an Administrator. Obtaining a Password: Launch the software to find your unique ID.

Email this ID along with proof of payment to the official racing shop (e.g., racingshop@mpsa.com). Enter the provided password to unlock the software. 2. User Configuration

A "User" in WinTAX4 is a specific layout and configuration file (usually a .zss file) tailored to your car model.

Import Snapshot: Place your car's .zss file into the C:\Wintax4\Export folder.

Apply Layout: In WinTAX, navigate to Setup > Users > Import User SnapShot. Select the file and the software will restart with the correct dashboard. 3. Data Connection (Ethernet)

The computer communicates with the car via an Ethernet cable (standard for most Peugeot/Citroën racing systems).

IP Configuration: You must manually set your computer's IP address to match the car's network subnet to enable data downloading.

Download: Once connected, use the Data Downloading function to transfer logged runs from the car to your PC. 4. Key Analysis Features

WinTAX4 uses "Layouts" to organize different data visualization windows: wintax 4 user manual

Analysis Windows: Includes multi-channel time/distance graphs, 2D/3D scatter plots, and histograms.

Linked Displays: All windows are linked; moving the cursor in one window updates the point of interest in all others.

Global Parameters: You can set global scales, colors, and alarms for each data channel through the Channel Parameters menu.

Overlay Functions: Allows you to compare multiple laps or even sync data with on-board footage or Google Earth tracks. 5. Advanced Customization

Keyboard Shortcuts: User-configurable "accelerator keys" allow for fast navigation during live pit-wall sessions.

External Modules: The software supports external DLLs for custom functions and mathematical calculations.

Unlocking Performance: A Deep Dive into the WinTAX4 User Manual

Whether you’re a professional race engineer or just starting your journey in data analysis, Marelli WinTAX4 is arguably one of the most powerful tools in your arsenal. This comprehensive data acquisition and analysis suite has been a staple in top-tier motorsport for over 20 years, supporting teams in everything from F1 and WRC to MotoGP. WinTAX4 is a professional motorsport data analysis platform

But a tool is only as good as the person wielding it. This post breaks down the essential sections of the WinTAX4 User Manual to help you get up to speed quickly. 1. Getting Started: Installation & Configuration

The manual starts with the fundamentals to ensure your system is track-ready.

Licensing: WinTAX4 comes in four levels: Junior, User, Team, and Pro. For the "User" level, you’ll typically need to provide your unique ID to Marelli technical support to receive a password.

Importing User Layouts: Each car model often has a specific "User" layout (a .zss file). The manual instructs you to paste this into your C:/Wintax4/Export folder and use the Import User SnapShot tool under the Setup menu.

IP Configuration: Since the car and computer communicate via Ethernet, ensuring your IP address matches the vehicle’s protocol is critical for successful data downloading. 2. Exploiting the Data: Visualization Tools

Once your data is downloaded, WinTAX4 offers a massive variety of windows to visualize it.

Graph Windows: View telemetry as waveforms against time or distance. You can easily overlay laps to compare performance or use the "difference" mode to see exactly where time is being gained or lost.

Google Earth Integration: One of the most useful features is the ability to plot GPS trajectories directly onto satellite imagery. This helps identify specific corners where a driver might be missing an apex or braking too early.

Specialized Displays: The manual covers advanced visual aids like GG acceleration diagrams (for lateral/longitudinal forces), histograms for parameter distribution, and customizable gauges for a cockpit-like view. 3. Advanced Analysis: Maths & Events

For those looking to go beyond raw data, the manual provides a deep dive into customization. Diagnostic Check Click Check Return (or F6 )

Virtual Channels (VCH): You can create your own mathematical channels using a graphical editor. This allows you to calculate "on-the-fly" metrics like aero balance or wheel slip using built-in trigonometric and algebraic functions.

Events & Alarms: You can set up automated "Events" to flag specific conditions—like an engine over-rev or a gear change—which will then appear as icons on your graphs for quick navigation. 4. Connectivity & Third-Party Support

WinTAX4 isn't a closed box. The manual outlines how to bridge your data with other professional software:

Excel & Matlab: Exporting data is as simple as a right-click, and the software supports two-way communication with Matlab and Simulink for advanced modeling.

Video Synchronization: You can link multiple video streams (like on-board footage) with your logged data for nanosecond-precise visual confirmation of what the telemetry is showing.

Diagnostic Check

Click Check Return (or F6) to run error/warning checks.
Results appear in Diagnostic Panel:

Errors – Must fix before filing
Warnings – Advisory, can be overridden with notes
Info – Informational messages

10. Troubleshooting

| Issue | Likely Solution | |-------|----------------| | Software won’t open | Run as Administrator; reinstall .NET 6.0 runtime. | | Calculation is zero | Ensure tax year is set correctly; check that filing status and SSN are present. | | E‑file rejected: Duplicate SSN | Another return already filed with same primary SSN. File an amended return instead. | | State return missing | Go to Return Navigator → State → Add State. | | PDF generation fails | Free up disk space; disable “Print as image” in PDF settings. |

E-File Preparation

Click Validate and Create E-File. The software generates a .txf (Tax Exchange Format) or .efr (Electronic Filing Return) file.
For test filings: Use Environment > Test (MeF ATS) before switching to Production.
