hello,
i am about to swap a 2.7t from an 01 a6, to my 01 a6 2.8. i have a donor car, so i have the harness, ecu, cluster, etc... my question is will i need to swap the ignition over also to avoid having it reprogrammed?

 

oh, and i will have some nice working 2.8 heads if anyone is interested in buying them. recently resealed cams, etc... make offer.
