Frequently Asked Questions
Straightforward answers to the most common ECU questions.
No. Your ECU is VIN-flashed on the bench with the latest authorized calibration before it ships. Plug it in and start the truck. In rare cases where a security relearn is required, we'll provide simple instructions.
Match the full OEM part number on your original ECU to the part number listed on the product page, including the letter suffix (AA, AB, AC, etc.). If they match, fitment is guaranteed.
Close is not good enough for ECUs. The numbers and letter suffix have to match exactly. Use the search by part number tool above or contact us before ordering and we'll confirm the right unit for your vehicle.
Professionally remanufactured OEM hardware, updated with the latest authorized software, VIN-flashed, and bench-tested on a simulator. If a unit doesn't pass, it doesn't ship.
