We will send instructions on how to complete this. During chekcout, be sure to put your VIN in the "notes to seller" field, otherwise we'll message after the purchase for your VIN.

A crankshaft and throttle relearn are also recommended when replacing the ECU. A scan tool is required to complete the crank and throttle relearn. Your vehicle may not run properly if these are not completed. Be sure your mechanic is capable of completing these before purchasing.
