thinking about getting a backup ECU where all 4 codes on the label match exactly ($80 +shipping at overseas wreckers).
just in case i get an ECU flash wrong (again!) or something else ECU related goes wrong, shouldn't happens anyways was thinkin
car is 07 facelift BPE outback with keyless entry and button start
is it possible to switch ECU's and reprogram the key ? or does the immobilizer system stuff up that scenario
