Unleash the BEAST

Your technical partner behind the workshop. We help automotive businesses deliver ECU tuning with programming tools, practical training, tailored tune files and ongoing technical support.

– TUNING PARTNERS –
– RETAIL & SPECIALIST –
Need help with your own vehicle or an unusual tuning job? We also take on selected retail and specialist projects.

Partners work with a team that has over 20 years of software programming experience behind every tune file.
You keep your customer base, bookings and pricing. We work discreetly in the background.
Our File Service works with a range of ECU programming tools, and we can help you change tools as you grow.
Screen sharing and a WhatsApp group in the early stages, so photos and videos are quick to share.
Read the ECU at your workshop, upload the file, and download the finished tune file.
Tell us about your business, vehicles and existing tools.
Get set up with suitable tools, guidance and file-service access.
Submit the original ECU file, vehicle information and requirements.
Work with our technical team on supported requests and next steps.
Two doors, a low seat and a Toyota 86 waiting outside. Sometimes that’s enough to improve your plans for the afternoon.
Owning a car you enjoy can turn an ordinary trip into something you actually look forward to. No elaborate excuse required.
If you’re considering a tune, tell us how you’d like yours to feel—and what you already love about it. We’re interested in your version of a good drive.

A Hiace can be a surprisingly personal space.
You know which pocket holds the receipts, which shelf the useful stuff lives on, and exactly who borrowed the thing that isn’t there anymore.
When you spend that much time with a van, the way it drives matters too. Tell us about your routes, your usual load and what you’d like from yours. We’re happy to get into the details.
What’s the one thing that always travels in your Hiace?
