The AEM sensor's are $70 new. SO $170 for essentially a new wideband isn't bad IMO
No, its not bad, but its not good either. You can get em for $10 more brand new. I would just buy a better controller if I were to get a used one, AEM may be the cheapest but they just dont seem as accurate to me, and arent exactly full featured.
