    Default Opened up grill

    Just wondering, the people that opened up the grills on their cars (VXRD comes to mind), does the car even get close to normal temp at the mo in this weather? I know a few of the lads I know with FMICs are complaining about boost cut due to low temps and cars going into limp home mode etc....

    as I say, just curious

    Boost cut? If anything I'd have thought it would rise slightly in the cold weather - certainly that's what I notice on mine. On a cold evening especially (when the air is denser) I see the boost pressure rise a bit. Being a pre-facelift my grille is open as well.

    I wonder if their cars are going into limp mode because of increased boost and spiking at too high a pressure?

    The FMIC shouldn't make a difference to the engine temp though - it's just cooling the charged air. The engine temp (coolant temp) shouldn't be affected by a FMIC as that runs through the radiator.
