You're wrong there, I found it more accurate than I expected.Originally posted by Stefan
.... how much richer your not gonna tell unless you got a wide band sensor or its RR'd under load and boost.
This particular gauge is pretty good, you'll see the electronics behind it. They do the real-time interpolating and averaging and the results are pretty meaningful (if you know what to look for)
We don't use the std sensor to set up the engine, who said we do?I would never use the standard sensor to set up my engine.
The std sensor is used for troubleshooting and avoiding any nasty surprises
Setting up is done on a wide-band sensor on a DYNO - this goes without saying!
true, that's why it's important to have a fresh sensor.BTW as the sensors get older the "switching" gets slower and closed loop performance suffers.
Also if the car burns lots of oil (or dodgy additives) then the sensor may be contaminated pretty quickly.
