Frequently Asked Questions

Orders with a confirmed VIN placed before 4 PM ET on a business day ship the same day. Anything after that ships the next business day. Every order ships Free UPS 2nd Day Air, so most units land within 2 business days of shipping.

Yes. UPS Next Day Air is a flat $40 on any order, any size. Select it at checkout. Same 4 PM ET cutoff applies for same-day shipping.

You'll get a tracking email and text within 30 minutes of the label being printed. If you don't see it, check your spam folder. Still nothing? Email support@omniflash.com with your order number.

We ship to the 48 contiguous United States only. We don't currently ship to Alaska, Hawaii, Puerto Rico, US territories, APO/FPO addresses, or international destinations. UPS needs a physical street address, so no PO boxes.

Reach out with your order number and we'll take it from there. If it arrived damaged, photograph the package and contents first and hold onto all the packaging until the claim is confirmed. If tracking shows delivered but you don't have it, contact us within 3 business days. Either way, we file the carrier claim on your behalf and work with you toward a resolution.

Modern ECUs are tied to your vehicle's VIN. Before we ship, we flash your specific VIN into the unit so it talks to your truck's CAN bus, security module, immobilizer, and dash exactly like the original ECU did. No relearns, no dealer trips.

Yes. There's a VIN field at checkout. We can't program a unit without it. If you forget, we'll email you to grab it before we ship.

If it hasn't shipped yet, no problem. Email us the correct one. If it's already shipped, send it back and we'll re-flash it under warranty at no charge.

Yes. Every unit runs on our ECU simulator before it gets boxed. We verify proper power-up, communication with the simulated CAN bus, correct input/output behavior, and a clean code scan. If it doesn't pass, it doesn't ship.

Remanufactured OEM units. Every unit is teardown-inspected, components replaced as needed, flashed with the latest factory calibration, bench-tested, and VIN-programmed to your vehicle. Same hardware as the dealer, same calibration, fraction of the price.

Yes. Disconnect battery, swap the unit, reconnect. No scan tool, no key relearn, no dealer visit. Because your VIN is already flashed in before it ships. In rare cases a security relearn is required, and we'll walk you through the simple steps.

No. The unit is fully flashed and VIN-locked to your truck before it leaves us. You don't need an SRS-capable scanner, OBD2 programmer, or dealer tool to make it run.

Yes. Your existing keys, fobs, and immobilizer data are unaffected. The new ECU is programmed to recognize your truck, not to wipe its security.

It shouldn't. Every unit is bench-scanned for codes before it ships. If you do see a code after install, it's almost always a sensor or wiring issue unrelated to the ECU itself. Hit us up before you assume it's the unit.

Usually 15 to 30 minutes, depending on your vehicle and where the ECU lives. Most are under the hood or behind a kick panel. If you can swap a battery, you can do this.

5 years, activated by returning your old core. Whether you're a shop or a DIYer, doesn't matter what you paid, it's five years either way. Send your old core back within 30 days of delivery using the provided shipping label. You're covered the moment you ship it.

No forms or registration. Your warranty activates when you return your old core within 30 days of delivery using the provided shipping label. A prepaid return label is already in the box, and any sturdy box works for sending the core back. You're covered the moment you ship it. Your order number is your warranty record. The old unit gets recycled on our end, so tell your installer to set it aside instead of scrapping it during the swap. If you can't return your core, contact us and we'll work with you.

Any internal defect or failure of the ECU itself. Component failures, communication issues, programming corruption, no power-up, anything ECU-related.

• Not covered: physical damage from external causes (water, fire, accident), modifications to the unit, or failure caused by a separate vehicle problem like a shorted harness.

See the full Warranty Coverage page for the details.

It depends on timing. Within the first 60 days, it's handled as a return: email support@omniflash.com with your order number, no diagnosis needed, and you get a full refund or replacement, your choice. After 60 days it's a warranty claim: send us your order number and a certified mechanic's diagnosis confirming the ECU as the failure point, and approved claims ship a replacement in 1 to 2 business days.

60 days for a full refund. Change your mind, ordered the wrong part, fixed the issue another way, whatever. As long as it's within 60 days of delivery, return it. No restocking fees. See Return Policy for the steps.

No core charge or deposit. You pay for the ECU at checkout, that's it. No money held, no card on file for a future charge. We do need your old core back though, since returning it within 30 days is what activates your 5-year warranty, and we recycle the old units. A prepaid return label is included, and any sturdy box works. If you can't return your core, contact us and we'll work with you.

Match the OEM part number printed on your existing ECU to the part number on our listing. Numbers match, it fits. Year, make, and model are just reference points. The OEM part number is the only thing that matters.

On the sticker label of your existing ECU. Usually a 8 to 10 character alphanumeric like P56041606AC or 56040365. Pop the hood, find the ECU, write down the number. If you can't see the sticker clearly, snap a photo and email it to us.

You're good. The year ranges listed are for reference. The OEM part number is the authoritative match. If yours matches ours, it fits regardless of what year shows up in the title.

We've got more inventory in the warehouse than what's listed online. Email support@omniflash.com with your year, make, model, and OEM part number. There's a good chance we have it.

Dodge, Chrysler, Jeep, and RAM from the late 90s through the 2010s. If you don't see your vehicle listed, ask. We've often got more in the warehouse than what's online and can usually source it.

If it hasn't shipped yet, yes. Email support@omniflash.com fast. We process orders quickly to hit the same-day ship cutoff, so the window is usually tight.

Before ship: yes, full refund, no questions. After ship: it falls under our 60-day return policy. Ship it back and you get a full refund.
