i have a 2004 wrx, but have seen a 2002wrx ppp ecu for sale and was wondering if this would fit my car.
What perfomance would i get if this worked with my car and if i needed any other upgrades to have this ecu working?

any help would be much appricated

The ecu's are different and I would not recomm that you swap them over it will work, but not really woth it unless you got one from an 03 onwards car, ie same shape car...
