For the free data transfer you must send us your old ECU to allow us to sync the data to the new unit. We aim to dispatch this within 2 working days, but please check with us first for turnaround times.

Please note: Unless you specifically request otherwise, we will not return your original ECU with your replacement. For some ECU's, due to the nature of the data transfer job, we will not be able to return the replacement.

Note, parts from 1998 and up vehicles are complicated and anti-theft systems have further complicated installation of used or new modules. Replacing an ECM in most cases require re-programming by a qualified Technician or high tech automotive locksmith. In most makes and models dealerships tools are locked by the manufacturer to prevent installation of used modules into a vehicle. Please verify installation procedures before purchase. We are not able to answer any questions related to installation. Buyers need to qualify the reprogrammers of the ECM to make sure they have the required tools or knowledge for each vehicle applications. If they are unable to program they will condemn the ECU as defective. Buyer hereby acknowledges that the sellers' liability is limited to the price of the item sold. We will not be liable for any damage or injury that results from any use of used auto parts or any other item sold on on our website.
