O2 Sensor,open/closed Loop

[avalonea]

When you turn it on hold the SET button from memory . or clr, should give you the version there

 

 

the 4 wire narrow band will be OK just for closeloop but any afr readings it gives will never be acurate, :hammer:

 

you can use any 2nd hand one as long as you can get the voltage map for it * so you can see wwhat voltage you get when its at stoich

Ok stoich means??????????

 

I was thinking the VL ones cause i think they are $ wire arent they or something similar

Ok stoich means??????????

 

stoichiometric, ie. 14.7:1 air/fuel ratio. theoretically the idea mixture ratio for cruise/economy conditions. pretty much what your narrow band o2 sensor does, is tell the computer if it is rich or lean and the mixtures are adjusted to suit in closed loop mode.

An o2 sensor is only required while tuning the vehicle. Factory vehicles use them to anylize the tune of motor because of changing climate conditions. What most people do is go to their tuning shop where the mechanic bolts a wideband o2 sensor onto the end of their exhaust (which has nothing to do with the wolf), and tunes the car on the road or dyno till it is spot on. He then removes his anylizer, charges you, and unless you further modify your car, or australia freezes over, your car will stay in perfect tune. You donot need to purchase an o2 sensor.
