Looking at getting one from OTTP one of the options is add LC1 WB controller ... what exactly is this? Something to do with a wideband?

 

mhm

WB= WideBand

i think? lol

it would make sense

 

Yes it is a wideband you could run to the interceptor if so desired to display your afr.

 

either you can get that and read your a/f ration on the interceptor. or get another gauge to just read wideband. either way works. it is up to you. personally i have a second gauge for wideband. that way i can monitor 2 other things on the interceptor.
