Saw this and thought it was worth my first post! Really great idea I wish my motor was quick enough for me to be interested in how much G I was pulling
I was just thinking, could you pull some of the data directly from the car itself (i.e. from the ECU) via the OBD port which a Subaru must have, then you could measure air temp, fuel mix, knock, loads of things without any external sensors?
Just a thought love the project though.
