Hey, on a side note, does your ecm have a built in map sensor? Mine does, which I thought would be for a turbo model, but my brother has a turbo 1.8 and a turbo 2.2 and neither one has a map sensor.
Im pretty sure thats not a MAP sensor.
(manifold absolute pressure sensor)
But a BARO sensor.
(barometric pressure sensor)
A map would have to have a vacuum hose coming from the manifold and plugged into the ECU.
I have never seen a stock subaru with a vacuum line, however i have seen them with a hole that looks like a BARO sensor.
