ECU SWOP?
 

if swoping a ecu from a std wrx to a ecu tek'd wrx ecu do the keys still need coding? i assume they will.... but just checking first, dont want plug the new ecu in and find not work then the old wont work as lost the key coding?

cheers in advance:thumb:

i would think so mate, as each key is programmed to it own ecu. i tried a swap with two sti's ecu's and it didnt happen, however one of the ecu's was a import so something to do with the immobiliser.
