Dealer vs. Professional Programming Why Pay More at the Dealer? Dealership ECM replacement typically costs $900–$1,975 and takes 3–7 business days — and many customers are surprised to learn the dealer rarely has the part on the shelf. Professional ECM programming delivers the same OEM-level precision at 50–70% less cost, with faster turnaround and no waiting room required.
