Getting Started
Start a request
Open a request in MavConnect, our customer portal, and tell us the vehicle, the module and what it's doing. A technician reviews it and sends your Technical Review — the price and the shipping instructions — in writing. Accept it, ship the module with any carrier (USPS, FedEx or UPS), and write your request number on the box.
WHAT'S COVERED
A technician looks first
Every request starts with a $195 Technical Review: a technician checks your part number, codes and photos against this service and confirms it's the right call before you ship anything. Go ahead with it and the $195 comes off your price. Want the module measured on the bench before we work on it? Add bench evaluation when you submit — $195 per hour, and you'll know the hours before we start.
WHAT TO EXPECT
Turnaround & warranty
✓ Turnaround: stated in your Technical Review and counted from the day your module reaches our bench.
✓ Warranty: six months on rebuilds and programmed replacements, when installed by a licensed shop.
✓ Programming: your module comes back with its own programming — plug in and drive. Programmed to your VIN — plug in and drive"
About ECU Maverick — ECU Repair, Rebuilding & Programming Specialists
ECU Maverick rebuilds, programs and clones control modules for European, domestic and specialty vehicles. Based in Fort Myers, Florida, we work with independent shops, dealerships and vehicle owners nationwide — by mail.
Where most shops replace and reprogram, we work at the board level: our technicians rebuild the circuits that fail, bringing back modules others write off. That comes from years of reverse engineering and bench work across thousands of control units.
Vehicles We Service
We specialize in European automotive electronics — BMW, Mercedes-Benz, Audi, Porsche, Land Rover, Bentley, Ferrari, Lamborghini, Maserati and Aston Martin — and also service domestic vehicles, heavy-equipment control modules and marine electronics.
Why Shops and Owners Choose Us
Price in writing first — Your Technical Review gives you the exact price before you ship. No surprises, and the $195 comes off your price when you go ahead.
Plug-and-play ready — Rebuilt modules keep their programming; replacements are programmed to your VIN. No dealer visit.
A technician, in writing — Every answer comes from the technician who has your file, on your request in MavConnect. You can read it twice, share it with your shop, and come back to it a year later.
Six-month warranty — On rebuilds and programmed replacements, when installed by a licensed shop. Full terms on your request.
Our Commitment
We exist to keep your vehicle out of the dealership and back on the road — a technician's honest answer, a price in writing, and the same care we'd give our own car, from the first message to the day the module is back in your hands.
