EXCHANGE SERVICE
If you choose the exchange service, we will send you a Rebuilt ECU/DME from our stock. Once you receive our rebuilt ECU/DME, then send back your defective ECU/DME core.
WHAT'S THE "CORE CHARGE"?
The CORE CHARGE is a deposit that we collect to ensure that the exchange is completed. When we receive your ECU/DME core at our office, we refund the core charge back to your credit card.
Your old ECU/DME must be returned within 5 days of the delivered date in order to receive the refund of the core deposit. You may be subject to additional charges, in addition to a canceled warranty, if you do not return your old ECU/DME within 5 days of receiving your new rebuilt ECU/DME.
ECU/DME's returned in NON-REBUILDABLE condition, such as HEAVY WATER DAMAGE, FIRE DAMAGE or MANIPULATED ECU/DME'S; may receive a partial refund, or no refund at all.
*FOR INTERNATIONAL SHIPMENTS ONLY* There is an additional $ 100 Core included in the shipping charges which count towards the core charge deposit. Once we receive the ECU core back, you will be refunded the original core charge plus the additional $ 100.
