Default Stack AFR Gauge

A couple of quick questions for those who have one:

1) Do you have to calibrate the sensor in free air?
2) Do the AFR readings fluctuate significantly when driving on/off boost or idling?

Thanks.

1) No
2) No not significantly, just as you would expect if the fueling/timing etc is constantly changing as it goes up or down the maps

When driving along (constant 40mph for example) the readings are never still and will fluctuate between 13.4 and 14.5.

To be honest, the reading never stabilises, even when idiling.

What spec/chip is it

Do the readings not even stabilise when you are just cruising and maintaining the same speed.

I should have stated that the gauge is fitted in a Renault 5 GT.

Also, the readings are never stable when cruising at a steady speed.
