i did datalogging on my sti on my car and i have question about my afr im getting 14.1 on idle and 11.7 on wot is it normal? or im getting almost 1600 on my egt gauge and im getting 100% on my fuel pump my mod is catted downpipe and 3 inch catback and accessport stage 2w/hwg

How are you getting the AFRs? 14.1 at idle is richer than it should be, 11.7 is what I usually tune for but if you are logging the stock O2 sensor then neither of those values are correct. Idle should be at 14.7 though.

when you idle, give it time, does it come back up to 14.7? maybe after 1-3 minutes?

its stay in 14.1 in long time. i think my o2 sensor is bad cause im getting .05-.06v instead of .02-.04v in idle.

not necessarily...the value you read is calculated from the voltage....but the car could really be doing it.

with constant throttle input(idle or crusing) mine always runs rich and then intime will lean out to the target...have not figured it out yet. my trims aren't changing at the time either...so go figure.

what is your egt temp.?^^
