Hey guys, I used to be able to do the idle relearn before, but all of a sudden it stopped working. I did this on my 2002 Nissan Maxima. I unplugged the TB, so I wanted to make sure the idle was okay. Also, do we need to update the software? Can you direct me to how if we do? Thanks in advance, Roger

How do I figure my Pin code for my 02 Nissan Maxima
