Nationwide mail-in service

ECU repair by mail for customers in every state.

Choose your state to find the diagnostic-first mail-in process for ECU repair, testing, cloning and programming.

One real service location, nationwide access.

ECU REPAIR operates from Humble, Texas. State pages explain how customers elsewhere can start an intake, ship a module for inspection and approve the final service only after diagnosis. They do not represent local storefronts outside Texas.

Why the diagnostic step matters.

ECU faults can resemble wiring, power, ground, immobilizer, programming and vehicle-side issues. The $150 diagnostic checkout begins the intake and inspection process before a final repair or cloning invoice is issued.
