Warranty & Coverage

Strong protection. Clear rules. No headaches.

Every OmniFlash ECU is programmed, tested, and shipped with care. Our warranty is simple, transparent, and built to keep you protected without the usual dealership nonsense.

1-Year Standard Warranty (Included)

Every ECU automatically comes with a 1-year warranty.

If the unit fails due to a programming or hardware issue, we replace it — fast.

Covered under the 1-year warranty:

  • ECU hardware failure
  • Programming or calibration faults
  • VIN mismatch caused by our process
  • ECU-related no-start conditions

If the issue is on our end, we fix it. No delays.

5-Year Extended Warranty (Free With Core Return)

Send your old ECU back using the prepaid label in the box, and we upgrade your coverage to a full 5-year warranty at no extra cost.

Why the upgrade?

Your returned core helps us maintain a fresh inventory of OEM units — so we reward you with long-term protection.

Core return = 5 years of peace of mind.

What Our Warranty Doesn't Cover

We keep this honest and straightforward.

The warranty does not cover:

  • Installation errors
  • Shorted wiring harnesses or electrical issues in the vehicle
  • Damage from other failing components
  • Water intrusion or corrosion
  • Physical damage
  • Wrong VIN provided by customer
  • Tampered or modified ECUs

If the ECU isn't the cause, it isn't covered — but we'll always help diagnose the situation.

Fast Replacement Guarantee

If the ECU is confirmed faulty:

  • We program a new one
  • Bench-test it
  • Ship it within 24 hours
  • Free 2-day delivery

No long forms. No runaround. Just fast, professional support.
