I swear that I have read on here mulitple times that the LC-1 wideband has to be calibrated everytime its used... I was on there website today and it clearly states that it self calibrates. So my question is, does it self calibrate or do you have to calibrate between uses?

 

it does not self calibrate, it does not need to be calibrated more than a couple of times a year ( if that often), unless you road race.

it does have a button you can push to have it "self calibrate", however you need to make sure it is in normal air. that can mean several different things, either you pull it out of the exhaust or you do some things to make sure the air in the exhaust is fresh.
