Ok ok...got that part...
Without the wideband...how will ube able to properly read the EGT gauge. If you have to compare readings with the wideband, and the EGT..in order to properly read the EGT? Not everyone uses or needs a wideband..And im not talkin about tuning..im just talkin about for monitoring. IM talkin about without the wideband..you cant compare a narrow band to a waideband.
