Getting Started

Submit Your Work Order

Fill out our simple work order form to get your unique tracking number. We'll email you shipping instructions immediately. Ship your module to us using any carrier (USPS, FedEx, UPS) or drop it off at our Fort Myers facility. Include your work order number with your shipment.

What's Covered

Thorough Bench Testing

Every module is tested before and after repair to ensure full functionality. If your unit tests fine, shows no issues, or is deemed non-repairable, a bench fee applies. We'll contact you before charging anything beyond the base service fee.

What to Expect

Turnaround & Warranty

✓ Turnaround: 2-3 business days (complex jobs may take longer)

✓ Warranty: 6 months on repairs we perform

✓ Programming: Not required—plug and drive

Who We Are

ECU Maverick isn't just another ECU repair shop, we're electronics nerds who happen to love cars. We've been reverse-engineering, bench-testing, and fixing control modules that other shops call "unfixable." While most places only reprogram or swap ICs hoping to solve the problem, we go deeper: component-level repair. That means we can actually diagnose and replace individual circuits on your module's board, not just clone data and hope for the best.


We're based in Fort Myers, Florida, and we work with repair shops, dealerships, and vehicle owners across the country. Our specialty? European brands like BMW, Mercedes, Maserati, Ferrari, Aston Martin, Audi, Porsche, and Land Rover — but we also handle domestic vehicles, heavy equipment, and marine electronics. If it has a control module, we've probably fixed it.

What Makes Us Different

Speed. Most jobs ship back within 2-3 business days. Need it faster? Same-day rush service available.

Plug-and-Play. Every module we repair or program is ready to install — no dealer visit, no extra coding. Just plug it in and drive.

Real People. Text us right now and you'll get a reply from an actual human in minutes. No chatbots, no ticket systems, no "please hold."

Honest Expertise. We've invested years into research and reverse engineering. We don't promise miracles — but when others can't solve it, we often can.

Our Mission

Keep you out of the dealership. Save you time and money. Get your vehicle back on the road — fast, reliable, and backed by our 6+ month warranty. Whether you're a professional shop or a vehicle owner, we treat every job like it's our own car on the line.
