Returns

30-day returns

You have 30 days from delivery to send a unit back. No restocking fee.

Before you send anything back

Call or text 812-510-3163 with your order number. 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 first. If the unit does need to come back, we tell you exactly where to send it.

Defective, damaged in transit, 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. These returns are settled with a replacement, not a refund.

You ordered the wrong part or changed your mind

The unit must come back uninstalled and undamaged, and return shipping is yours. Once it arrives and we have checked it over, we refund the purchase price to the payment you used. Shipping charges, including a UPS upgrade, are not refunded. Allow a few business days for the refund to show on your statement.

Cancelling an order

You can cancel your order for a full refund any time before it ships. Once it has shipped, it can only come back as a return.

After 30 days

Returns close at 30 days, but the unit is still covered by our one-year warranty. 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, and 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.

VIN and programming mistakes

• If we programmed the wrong VIN or the wrong calibration, we fix it and pay the shipping both ways.
• If the VIN you gave us with your order was wrong, we reprogram the unit, but the round-trip shipping is yours.

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.
