Thread: intercooler budget build shortstack

Do those wideband have to be open air calibrated?

im not entirely sure? probably and I never did it

that would be a cheap and easy fix lol I always just thought that having the key in the on positon would be an open air calibration though as long as the engine was off because its technically open air in the exaust during that time

You can't calibrate with it in the exhaust because there will always be exhaust fumes that remain in the pipes. You have to pull it out and go through the calibration process in the link. I mean, double check your model number. Some sensors like my AEM don't not require it.
