the title of my thread is wrong sorry guys. i have an sf3 and im using the livelink datalogging software. another question i have is; is you spark supossed to retard when you step on the pedal for a sec then advance? because when im cruising at a constant speed then step on the gas somewhat my spart retards before it advances?? is that correct. and also could someone inform me about the long term and short term fuel. also how influential are the rear o2 sensors. because my bank 2 rear sensor isn't reading anything. could it be burned out due to my smashed cat??? sorry for the long post im just trying to learn about this ish.
