im not entirely sure what the 3 bar means in to conjunction with the o2 readings
but from what i was told is that "its ridiculously accurate wide band,it has a much broader range than many others on the market. its a 3 bar to put in better terms" "what like a maf sensor?" yeah but for your exhaust"
reese,not a problem man just glad we could help. lemme know if you need anything else.
