About ECU Maverick — Expert ECU Repair & Programming Services

ECU Maverick specializes in component-level ECU repair and programming for European, domestic, and specialty vehicles. Based in Fort Myers, Florida, we serve independent repair shops, dealerships, and vehicle owners nationwide.

Where most shops rely on reprogram-and-replace methods, we take a different approach. Our technicians diagnose and repair individual circuits at the board level, restoring modules that others write off as failures. This expertise comes from years of reverse engineering and bench testing across thousands of control units.

Vehicles We Service

We specialize in European automotive electronics, including BMW, Mercedes-Benz, Audi, Porsche, Land Rover, Bentley, Ferrari, Lamborghini, Maserati, and Aston Martin ECU repair. We also service domestic vehicles, heavy equipment control modules, and marine electronics systems.

Plug-and-Play Ready — Every module leaves fully programmed and coded to your vehicle. No dealer visit required.

Direct Communication — Text or call us and speak with a real technician. No ticket queues, no waiting.

6-Month Unlimited Mileage Warranty — Drive with confidence. Our warranty covers you regardless of how many miles you put on.

Our Commitment

We exist to keep your vehicle out of the dealership and back on the road—with reliable repairs, transparent pricing, and expert support from start to finish. Every job receives the same attention we'd give our own vehicle.
