Different applications with different sensors
Olddog If you have a heated o2 sensor the readings are almost perfect after 15 seconds of startup. Doesn't matter if it's a wide or norrow band sensor. If non heated, will take up to 5 minutes depending on location of the sensor and how cold it is out. Old sensor needed about 600f temp to start working correctly. The only problem is the sensor couldn't burn off the carbon verywell and the sensor become slow to respond. Wide band sensor are more for power adder motors because you need alot more fuel with a supercharger, turbo or NOS. The narrow ones are more for emmissions and fuel control. Trying to keep the motor running lean as possible and keeping the tail pipe clean also.
As far as respond to motor running, the one ones are so fast we have to use a snapshot to read the numbers from a scanner. They are as fast or slow as the speed of the computor they are hooked too. Rick L.
