WinOLS Advanced Heavy Diesel In-person Course – 3-Day Training

Build advanced skills with WinOLS Advanced Heavy Diesel In-person Course

The WinOLS Advanced Heavy Diesel In-person Course gives experienced tuners practical skills to tackle complex heavy-duty ECU calibration with greater confidence. Join Simon White, Technical Director at VIEZU Technologies, at VIEZU USA headquarters in Salt Lake City, Utah, from March 21–23, 2027.

Train on real ECUs and explore platforms from Bosch, Delphi, Cummins, Volvo and CAT. You’ll strengthen your understanding of DTC logic, torque supervision and emissions-system strategies, then apply a structured workflow to building repeatable, commercial-grade solution files. The result: techniques you can bring back to your tuning business and use across trucks, agricultural machinery and construction equipment.

Course highlights

• Hands-on training across six heavy diesel ECU platforms
• Advanced WinOLS methods for diagnosing and modifying DTC logic
• Practical guidance on torque models and complex control strategies
• Coverage of EGR, DPF and SCR systems for applications where permitted by law
• Continued technical guidance from VIEZU after the course

This advanced training is designed for professional tuners who already know WinOLS and have hands-on tuning experience. It is not suitable for beginners. Any emissions-related work must comply with local regulations and is intended only for applications where permitted.

Take the next step in your heavy diesel specialization and return with practical skills to put to work. Reserve your place and make the most of three focused days with an experienced technical instructor.
