Built on experience.
Driven by enthusiasts.

Automotive electronics is our work. The cars, the builds and the people behind them are why we do it.

Relentless Motorsports TX

Hands-on experience.
Personal attention.

Founded by Josh Beaumont, Relentless draws on more than 20 years in the automotive world, including 11 years in automotive technology and electronics.

We assess supported ECUs, instrument clusters and selected electronic modules for vehicle owners and repair shops. Mail-in service connects that work with customers around the world.

Our approach is straightforward: understand the reported fault, review the diagnostic work, inspect the electronics and explain the available options. Every module deserves an individual assessment.
