STRAIGHT ANSWERS

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.

Orders with a confirmed VIN placed before 4 PM ET ship the same business day. Free UPS 2nd Day Air on every order. UPS Next Day Air is available at checkout for $40 flat.

Standard on every unit, no registration required. Coverage activates the day your ECU is delivered. If your unit fails within 5 years, contact us with your order number and a certified mechanic's diagnosis. Approved claims ship a replacement in 1 to 2 business days.

No. We don't charge a core fee or hold a deposit at checkout. You pay for the part, you get the part. No money held hostage waiting on a return.

Contact our support team first so we can help verify wiring, grounds, and diagnostics. If the ECU isn't the fix, you have 60 days to return it. No restocking fees, free return shipping.
