[Diy_efi] wide band O2's

[Brian McMahan]

PLX widebands utilize the latest digital PID and DSP technologies to
maximize o2 sensor reaction time and accuracy without compromising
overshoot, and slow settling response time. This technology is coupled
with advanced self sensor calibration circuitry and sensor soft start to
both prolong the life of your oxygen sensor as well as eliminating any
user intervention for manual sensor calibration. PLX widebands may be
used and installed in your vehicle permanently.

This was taken directly from their website for further info pleas refer
to www.plxdevices.com <http://www.plxdevices.com/> 

As a matter of fact I'm going to call them today and see what they have
to say about the automatic calibration.

Yes, the 'free air' reference from another post. 

 

Brian, with sensor 'drift' a normal characteristic of WB sensors,

(especially in performance environments), I question the solution 

to the problem, when free air test shows sensor drift, and analog 

circuitry unable to provide for manual (re)calibration.

	You have a point. There's always an easy way to check though
just take 

	it out and let it sit then check what AFR it's reading.

	BTW, I was referring to digital processing, not necessarily the 

	display.  Another thing regarding the PLX; there is no 'in use' 

	manual calibrating.  It is my understanding, it relies strictly
on 

	the sensor's calibration resistor.  Again, I question the
accuracy, 

	especially after it has been in use for some (hours) time.
