Viezu Technologies and Viezu Technical Academy return to Las Vegas and SEMA for 2026. Fit your training from leading experts around the show. Extend your SEMA Show networking with our Vegas training events that top and tail the show itself. Meet likeminded professionals and share knowledge.

The lead trainer for this diesel ECU tuning event is renowned UK-based tuner and tuning trainer Simon White – technical director and managing director of Viezu Technologies. This is expert practical training that goes beyond the theory – from real-world tuners.

This is an intensive course, pitched at Intermediate level. This course will take you from a basic WinOLS user level and build on that, to give you more confidence in your WinOLS diesel ECU tuning and diesel calibration, and higher level skills and techniques that you can use straight away to grow your tuning business.

This SEMA in-person event is not for WinOLS absolute beginners – to get the benefits and full value of this course, you do need some real-world experience of tuning with WinOLS, and a working knowledge of the software.

If you have already completed Basic level in-class WinOLS training with Viezu, or if you have completed the first 4 Viezu Training Academy online training modules for WinOLS diesel, then you have the knowledge needed for this SEMA in-person course.

If you need any Viezu training to help you prep for this SEMA course, then contact us on info@viezu.com or on +44 (0)1789 774444 – we can discuss your requirements and get you set up.

Group sizes are small on our courses, so we are able to tailor content to your needs. We encourage you to contact the lead trainer Simon White in advance to discuss any specific training topics you would like to cover. For example, if you work with particular vehicles or engines, we can include these in our example projects on the course.

By the end of this 3-day course, you will be able to: 

• Confidently navigate and modify diesel ECUs using WinOLS at an intermediate level
• Build and adapt mappacks, import previous calibration data and manage complex projects 
• Tune vehicles with stock hardware and upgraded hardware (large turbos and injectors) 
• Produce safe, coherent torque/boost/fuel strategies with strong drivability
• Use dyno/log feedback to refine your calibrations professionally 

Who this course is for:

• Tuners already using WinOLS actively in a professional diesel tuning environment
• File developers who want to extend their knowledge into diesel calibration services
• Tuning businesses looking to extend their diesel tuning and calibration offerings to higher levels

Pre-qualify yourself – is this course right for you?

• Have you completed beginner-level WinOLS diesel training – or do you have equivalent practical working experience of WinOLS diesel tuning?
• Are you currently tuning diesel vehicles using WinOLS with consistent success?
• Do you understand diesel map relationships, and the concepts and use of mappacks, projects, and project structures?
• Are you working on EDC16/EDC17/Siemens/Continental ECUs?

If the answer’s ‘yes’ to all the above – you’re ready. If not, reach out and let us help you pick the right entry point to develop your knowledge. You can email us or give us a call.
