In response to demand for specialist training in tuning diesel-engined heavy trucks, tractors and agricultural machinery, and heavy construction equipment, VIEZU Technologies and VIEZU Technical Academy are pleased to announce these extra training dates in Miami, Florida, in August 2026.
If you are in North America, this is a rare chance to access in-person heavy diesel ECU tuning training from the leading European experts.
This training will address the key questions about large diesels that come to us frequently, including diagnosing and fixing problems with emissions control equipment, and advanced emissions solutions.
The lead trainer for this heavy 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-Advanced level. If you are already using WinOLS, and maybe also using it with heavy diesels, this course will build on and extend those skills, and give you specialist knowledge and higher level skills and techniques that you can use straight away for a range of heavy truck, tractor, agricultural machinery, and construction equipment tuning jobs.
This USA in-person event is not for WinOLS absolute beginners. To get the benefits and full value of this course, you do need some real 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 basic knowledge needed as a starting point for this in-person course.
If you need any VIEZU training to help you prep for this heavy diesel tuning 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 can 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.

Hear what students from a recent course had to say
You need to bring a laptop with genuine up-to-date EVC WinOLS software installed and running smoothly. You will need the full version of WinOLS, as the demo version does not have all the features you need for the training.
You can purchase full version WinOLs software on the Viezu Technologies website.
Who this course is for:
- Tuners already using WinOLS actively in a professional environment
- File developers who want to extend their knowledge into heavy diesel calibration services
- Tuning businesses looking to extend their diesel tuning and calibration offerings to heavy trucks, agricultural machinery, and construction equipment
- Diesel specialists who want practical, in-person training on commercial-grade emissions and diagnostic logic solutions
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, DTC logic, torque modelling, and the concepts and use of mappacks, projects, and project structures?
- Are you working, or planning to work, on heavy truck, tractor, agricultural machinery, or construction equipment 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.
