SEMA 2025: Viezu's Tools, Training and Tuning in Front of the World
At this year's SEMA Show, the Las Vegas Convention Center turned into a worldwide showcase for the aftermarket tuning industry. Viezu Technologies set up at Booth 24643 and attracted tuners, tool suppliers and enthusiasts from around the globe. With the UK head office and Viezu USA both on hand, the stand became a center of live demos, hands-on training conversations and real business.
A McLaren, a Crowd and a Message
Training and tuning support are at the heart of what Viezu does, but presence matters too. The McLaren on our stand quietly signaled the caliber of vehicle platforms our dealer network supports. It wasn't the point of the booth, but the message landed: Viezu is in the game wherever performance counts.
Booth 24643: The Whole Tuning Ecosystem
This was more than tools in a display case. Visitors saw complete workflows, from the first ECU read through ECM Titanium or WinOLS to file creation and flashing. They met the people behind the software and left knowing more than when they arrived. Having Viezu UK and Viezu USA working shoulder to shoulder showed our reach and our readiness to support tuners anywhere.


Live Demos, Genuine Conversations
Demonstrations turned into two-way sessions. Tuners asked technical questions, tried the interfaces and got practical answers right there. Our ECM Titanium webinars and StageX masterclasses from earlier in the year came to life on the stand, giving confidence to visitors ready to take the next step.
From Questions to Kits: Sales on the Stand
The engagement spoke for itself. Several visitors bought KESS3 and AutoTuner tools at the booth, some adding training on the spot. They could see the whole package (the tool, the training and the support) ready to go, with no sales pressure.
UK Tuners Abroad
SEMA may be in Las Vegas, but it felt like an international meetup. UK tuners, including Alan and Mark from Central Garage in Paulton near Bath, dropped by for a chat.

Good Company: AutoTuner and MAGIC Motorsport
We had our own hub, but the show was also a perfect chance to see our tool partners in person. We visited the AutoTuner and MAGIC Motorsport booths to film informal updates and strengthen our working relationships, which underpin the service we provide and keep our community ahead of the curve.
Stars, Screens and the Scene
SEMA always draws star power, and this year was no exception. Jay Leno and Fast & Furious actor Sung Kang were in the hall, with Kang presenting at the SEMA Industry Honors and showing his AE86 from the upcoming film "Drifter." It all confirmed what we already knew: tuning culture isn't niche anymore, it's mainstream, and Viezu is right in the middle of it.
Part of a Wider Tuning Group
Viezu doesn't stand alone. It's part of a group that includes Paramount Performance, known worldwide for Jaguar tuning and high-end mechanical upgrades. Together, the brands serve everyone from classic car collectors to performance shops wanting to add remapping to their services.
Training That Goes Where You Are
Many visitors were impressed by how flexible our training is. Between in-person Viezu Technical Academy courses in the US and our online platform Remap101, tuners can learn wherever and whenever suits them, and that accessibility has helped our network grow into more than 80 countries. We weren't only in Las Vegas for the show, either: 15 tuning professionals joined Technical Director Simon White before and after SEMA for in-person EVC WinOLS Diesel and Gasoline courses, and we're already planning more for 2026.
Filmed, Edited and On the Way
We filmed the whole week: interviews, tool walkthroughs, crowd moments and testimonials. Catch it all on our YouTube channel, starting with our new release, "Which tuning tool should I buy – Viezu at SEMA 2025," which is live now.
From Las Vegas to Your Shop
SEMA 2025 was more than a trade show. It proved tuning is a serious global business and that Viezu is one of the few offering a complete solution: tools, training, support and experience for tuners who want to grow. If that's you, we're ready when you are.
See You at SEMA 2026!
We're already booked for SEMA 2026 and will be exhibiting again, with our world-leading WinOLS Diesel and WinOLS Gasoline training before and after the show. We'll announce details in summer 2026, so check back for more on our plans.
