bit of a queery on gen 1 codes

[Skidmarx]

hi guys and gals :)),

recently acquired my boost by smith interface, and have been fiddling around, since finally getting it setup (nightmare in itself) iv managed to flash it with a very basic tune, now my FI light is on, i checked codes and its showing up with C44, now after having a look around, thats supposed to be a gen2 02 sensor code.............. anyone have any ideas on this?

all help greatly appreciated :)

cheers ash
