About Us
At Auto Attic, we're a family-owned business with a simple mission: get the right module to the right vehicle, the first time.
We specialize in quality-tested, used OEM ECUs and control modules — engine computers, transmission controllers, airbag modules, ABS units, body control modules, and more. Every unit in our inventory is bench-tested and verified before it's ever listed for sale, so you can order with confidence.
What We Sell
We carry over 4,800 OEM control modules spanning 800+ makes and models. Whether you're a DIY mechanic, an independent shop, or just trying to get your daily driver back on the road without a dealer markup, we've got you covered.
Please note: Most ECUs and control modules require programming or relearning after installation. This is normal for used OEM units. Reprogramming is typically performed by a dealership or qualified automotive locksmith using the VIN of your specific vehicle. If you have questions about programming requirements for a specific unit, feel free to reach out before ordering — we're happy to help.

- Bench Tested — Every unit is verified functional before listing
- 90-Day Warranty — Coverage on every module we sell
- Fast Shipping — Same-day shipping on orders placed before 2 PM
- Easy Returns — Hassle-free 30-day return policy

Why Auto Attic?
We've been selling on eBay with a 98.6% positive feedback rating, and we bring that same commitment to every order. We know how frustrating it is to wait on a part, get the wrong fit, or deal with a module that doesn't work. That's why we verify fitment carefully, test every unit, and back everything with a real warranty.
Thanks for shopping with us. If you have any questions, don't hesitate to contact us.
