im wondering ive already repinned my bg5a TT legacy loom to suit 3plug v3/4 was wondering if it would be easy to convert to the earlyer 4 plug wrx ecu.
reason being is being able to get a chipped 4 plug ecu to get rid of speed cut
raise rev limiter and boost cut. a much cheaper option than spending 2grand to install and get a link.
i cant seem to find ecu chips to fit v3/4 ecu's and everyone says just get a possum or g4 link lol.
