In response to demand for specialist training in tuning diesel-engined heavy trucks, tractors and agricultural machinery, and heavy plant – VIEZU Technologies and VIEZU Technical Academy are pleased to announce these extra training dates at VIEZU USA in Salt Lake City in April.
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.
You will get time on the dyno in the Viezu USA / Adrenaline Dyno fully equipped workshop.
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 plant 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.

Prerequisites and what you need to bring with you
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 – 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.
We are always happy to talk with you and discuss your individual training needs, to help you build your tuning skills and grow your tuning and calibration business.
