narrow band a/f gauge

can i tune my safc 2 with a digital narrow band A/F gauge, not the one with the blinky lights, this one shows the voltage. if so what are some good numbers i read .88v-.92v, is .88 to lean? and the leaner, the hotter, but more power?
thanks

mmm....never heard of that being done....you will get the best results with using a wideband

The narrowband o2 sensor voltage should be used as a very rough source of data only In other words, just use it to make sure everything is in check and that you're not completely off the map. Don't use it solely to do any actual tuning, though. .88v-.92 is definitely on the map, so you have no worries. FWIW, I hardly pay the narrowband front o2 any attention at all when I'm tuning. Just use it to make sure you're in the ballpark :)

See www.posracing.net/afr.html for my thoughts on narrowband O2 sensors. While the digital readout is more useful than the blinkylights, it is still only as accurate as the sensor itself.
