rb25det series II o2 sensor - where to get?

[paulr33]

seems ok, only done about 60ks since its been done. will let you all know when i refill the tank. anyone know how to configure the apexi auto timer to show the a/f i checked the manual and the bit i dont get is: it says

select a/f and press right then set the a/f to the value from above table according to what the o2 sensor voltage is. and the o2 voltage gets displayed for a quick second. so i set it based on what the o2 value is, about 11.0 so i set a/f to 950

then it says to set o2 value

select o2 and press right, then set the o2 to the value from the above table according to what the a/f value is. and the a/f gets displayinf for a brief second 950 and goes back to showing the o2 which is 11.0

i dont get how that works, so if i set the o2 voltage to 20 then the a/f is wrong and if i set the a/f wrong the o2 is wrong, it seems incorrect. wouldnt the o2 come from the ECU ? and be static and then a/f be set based on what the o2 reads?

seems strange that i set and calibrate both based on each other, as they depend on each other

ive got 1/4 of a tank left and ive done 244 k's. the o2 sensor was changed when i had half a tank

350kms to a full tank. seems more realistic now. previously i was getting 250km's to a full tank. 100km difference thanks to the busted o2s sensor. my old one is my desk and when i shake it, it rattles. the thing thats annoyed me the most, is that ive had it serviced every 10,000 and its never been found as a problem., ie: its never been checked / replaced. its supposed to be done every 40,000 and ive had the car more than 40,000k's. sucks that ive had to find and fix this myself, this is what car dudes are paid for with each service.

oh well

if your fuel economy sucks check your o2 sensor
