Hi , what would the ecu code number be for an 260 ps ecu .I know that a z4 is one but that is for the early impreza and mine is a p reg 1996 facelift wrx wagon import with 3 plugs going in to my ecu.
many thank Russ

 

p reg should be after facelift .z4 is 4 plug.. you said yours was 3 plug (after 96). ive put a z4 in mine and more boost but is 112mph limited... think youd be better of geting yurs chipped and mapped to suit yur car!!
