Why Buy AutoECMs?


Over 20 years of dedicated service to consumers like you who need quality remanufactured automotive electronic control modules (ECMs), also known as electronic control units (ECUs).


We stand by our parts and offer a 1-year warranty on most of our parts (see exceptions under Warranty Information). If you find that your part stops working within the first year of purchase, we will send you a free replacement electronic control unit (ECU) shipped Next Day Air.

Huge Inventory

We have over 400,000 units in stock. After time, dealerships discontinue producing parts for less popular, older vehicles and our inventory supports your need for a discontinued part. Chances are if we don’t have it, no one does. We have stock on rare and hard to find pieces.

Understood Urgency

We know that when your car is not working, that you want it back on the road as soon as possible. If you place your order by 3:30PM EST Monday - Friday for an item in stock, we will ship your part the same day.
