Frequently asked questions

What if you do not have the computer that I need in stock?

If you order a vehicle’s computer module and we do not have one in stock, we will locate one immediately and notify you of the expected delivery time. This usually takes 1–2 days. It is very rare that we will not have your part in stock.

Can I return my computer if it doesn't work?

Yes. The part may be returned within 30 days of delivery as long as it is in its original condition. Returns are subject to shipping charges and a 25% restocking fee. It is the responsibility of you and your mechanic to properly diagnose your vehicle before ordering. No returns are accepted after 30 days.

What happens if I do not return my old computer?

Exchanges are required for all purchases unless otherwise directed. If you do not return your old engine computer module, you may be charged a core fee and your warranty may be voided. If you wish to keep your old part, please call us before ordering to review your options.

How soon will I receive my computer once I have placed the order?

We ship Monday through Friday. Ground shipping takes 1–6 business days, depending on location, while air shipping is 1–2 business days. Orders placed before 3:00 PM Eastern may ship the same day. Most orders ship within 24–72 hours.

Do I need to have any additional programming done once I receive my part?

Most powertrain control modules and electronic control modules we sell are plug-and-play. All Chrysler products are pre-programmed. Some Ford and Honda models may require a locksmith to calibrate the ignition after installation.

Where can I find my VIN?

Your Vehicle Identification Number (VIN) can usually be found:

On the dashboard near the windshield
Inside the driver-side door frame
On your vehicle registration or insurance documents

What is a VIN number?

A VIN (Vehicle Identification Number) is a unique 17-character code that identifies your vehicle. It includes details about the manufacturer, model, engine type, and production year.

What does plug-and-play mean?

Plug-and-play means the engine computer module is pre-programmed and ready to install. Once installed, it will function properly without any additional setup.
