i have a Jaw wide band for sale 90$ shipped with a used sensor. <1500 miles on the sensor still getting single digits on the cal. the last one I did was a 4. the unit works great just not with eCtune due to data logging voltage offset issue. if you are wanting a cheap yet reliable wide band here it is
