OK sorry i noticed its only the euro spec busa's have the o2 so sorry about that , kinda odd they didnt use one seeing as its alot more flexable and more controlable to the a/f ratio for both performance and reliability. Usually the fuel maps of like a car are for the a/f ratios at the given rpm and engine load based off the readings. Never really messed with the emissions equipment on my busa just assumed since its efi it would use an oxygen sensor. Learn something new everyday lol
