An EASIER way ??

I read alot of places about recalibrating the wideband. Normally requires the process of jacking up vehicle, getting under the vehicle, unbolting(removing) the O2 from the bung, letting it hang in free-air, then run recalibrate process. Another option....? After vehicle has been sitting overnite. Before starting vehicle next day. Remove a spark plug, make sure on exhaust stroke and exhaust valve open. Then grab air hose from compressor, grab blow nozzle with rubber tip, press rubber tip into spark plug hole, blow air while recalibrating.

i did it on my personal car just by recalibrating after it had been sitting a few days, its not like a pipe with no flow is starved form oxygen, and its spot on with my narrow bands. But just dont do it right after the car has been running lol

Yep. Right after vehicle stopped would not be free
air, lol

The luck ive had with bosch sensors on my aem unit it does not need a calibration. Id really recommend doing it the correct way or leave it alone.

yea for custumer cars or alike just do it correctly.. im using the inovate LC2 digital signal type, that one also requires to be unscrewed to get a propper calibration. but yo just need to know what "good enugh" is for you

We honestly dont know how accurate some of these cheap widebands are to begin with. Ive noticed some of the counterfeit aem units will read richer when rich and leaner when lean.

Do you always use lambda?
