Warranty

One-year warranty · 30-day returns

Every unit we sell is covered for one year from the day it is delivered. There is nothing to register and no form to fill in — your order number is your warranty record.

The first 30 days

You have 30 days from delivery to send a unit back, with no restocking fee.

Call or text us first. Most no-start problems after a computer swap turn out to be something else on the vehicle, and we will help you check the simple things before you box anything up.

If the unit is defective, arrives damaged, or we sent the wrong part, we send you a replacement with a prepaid return label in the box. Pack the unit you are returning in that box and send it back with the label — the shipping is on us.

If you ordered the wrong part or changed your mind, the unit must come back uninstalled and undamaged, and return shipping is yours. We refund the purchase price; shipping charges are not refunded. See our Returns page.

After 30 days: one full year

If the unit fails after the first 30 days but within one year of delivery, send it back to us for testing. Shipping it to us is yours. Testing and repair usually take two business days from the day it arrives. If it is faulty, we repair it or send you a replacement programmed to your VIN. We pay to ship it back to you either way — even if testing finds nothing wrong. Warranty claims are settled with a repair or a replacement, not a refund. Coverage continues on the repaired or replacement unit from your original delivery date — it does not start over — and it applies to the original purchaser and the vehicle the unit was programmed for.

Your old unit

There is no core charge and no deposit on any unit. For most engine computers, keep the old one or scrap it — we do not need it back.

Cummins diesel ECMs are the exception. To keep the one-year warranty on a Cummins ECM, your original ECM must come back to us within 30 days of delivery. A prepaid return label comes in the box with your new ECM. Ship your original back in that same box, with the same packing, so it arrives in one piece.

What is covered

  • Defects in the unit's components or in our workmanship
  • Internal failure of the unit in normal use
  • The unit not communicating with the vehicle it was programmed for
  • Our programming — if we programmed the wrong VIN or the wrong calibration, we fix it and pay the shipping both ways

What is not covered

  • Damage from installation — bent pins, forced or half-seated connectors, or the unit powered up with a plug not fully latched
  • Water, fluid or moisture inside the unit
  • Physical damage from impact or dropping, an opened case, or any repair or reflash attempt by anyone but us
  • Problems on the vehicle side — wiring shorts, bad grounds, failed sensors, a bad alternator, a dead battery, or aftermarket alarm and immobilizer trouble
  • A wrong VIN given to us with your order — we will reprogram the unit, but the round-trip shipping is yours
  • A unit installed in a vehicle other than the one it was programmed for

How a claim works

  1. Call or text 812-510-3163 with your order number and what the vehicle is doing. We go through it with you on the spot — often it is a ten-minute fix and nothing needs to ship.
  2. Within 30 days of delivery: if the unit is the problem, we ship a replacement programmed to your VIN, usually the next business day, with a prepaid return label in the box. Send the failed unit back in that box within 30 days of receiving the replacement.
  3. After 30 days: send the unit back to us for testing — we tell you exactly where to send it, and shipping it to us is yours. Testing and repair usually take two business days from the day it arrives. If it is faulty, we repair it or send you a replacement programmed to your VIN. We pay to ship it back to you either way — even if testing finds nothing wrong.

What the warranty does not pay for

The warranty covers the engine computer itself. It does not cover labor, towing, diagnostic charges, rental cars, or other parts on the vehicle.

Your legal rights

This warranty gives you specific legal rights, and you may have other rights that vary from state to state.
