hi guys i have recently bought a 97 forester but i cant get any of my diagnostic software to work on it , i have tried elm327, freessm, proscan,to name but a few but none will comunicate with my ecu. i have read that freessm only works with 99on models so was wondering would a straight swap with a 99 ecu work on my car as is or is there any software out there that works with this model. thanks in advance any help will be apreciated.
