Hi Mike

This should help

http://www.enginebasics.com/EFI%20Tu...%20Basics.html

But Narrow band sensors are only accurate right at 14.7:1 air/fuel ratio by weight. They are very inaccurate above and below that.

Wideband is highly regarded as best for tuning and for correct readings of AFR/fuelling etc.

Maybe due this mappers using Wideband for mapping the cars than Narrowband lambda sensors

Hope this help there

Narrow band basically reads rich or lean not by how much!
