so i'm wondering,

i'm going to be getting a safc neo and i need a wideband reader, should i get an lm1 cause i hear it's one of the best, or something simpler?

can someone quickly explain to me how the 2 work together?
so they connect to each other?

 

no they dont connect. its alot better to have both for easier tunning. and im selling my wideband.... 2 month old ngk afx. pm if intersted
