Frequently Asked Questions

Orders placed before 4 PM ET on a business day ship the same day. Orders after that go out 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 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.

Currently, no. We ship within the continental US only. Hawaii, Alaska, and PR ship at the same UPS rates but transit time varies. International shipping is on our roadmap.

We've got you. Reach out and we file the UPS claim on our end. You get a replacement unit shipped right away, no waiting on the carrier investigation. Don't toss damaged packaging until we confirm the claim.

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.

Refurbished 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.

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 from delivery. Standard on every unit. Doesn't matter if you're a shop or a DIYer. Doesn't matter what you paid. Five years either way.

No. Warranty activates automatically the moment your package is delivered. No forms, no registration, no calling in to confirm. Your order number is your warranty record.

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 Policy for the details.

Email support@omniflash.com or call (223) 895-7182. We'll send a prepaid return label and ship a replacement same-day in most cases. No back-and-forth, no proof of fault required.

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. You pay for the ECU at checkout, that's it. No deposit held, no card on file for a future charge. We do appreciate getting your old unit back so we can refurb it for the next customer. We'll send you info on that after delivery.

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 or call (223) 895-7182 with your year, make, model, and OEM part number. There's a good chance we have it.

Primary focus: Dodge, Chrysler, Jeep, and RAM from the late 90s through the 2010s. We're expanding into Ford and GM platforms next. If you don't see your make, ask. We 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.
