Hey guys, have anyone tried replacing the stock O2 sensor with just the Bosch LSU4.2 5-wire, wide-band O2 sensor from the LM1 to the Datalogit box? if so which do I connect it to and will it run just like it had the stock O2 sensor? will it run better? as far as PFC fuel sampling? or does the PFC even do fuel sample? I sure it does to adjust AFR.

 

A wideband o2 sensor REQUIRES a control unit...you can't do what you're proposing.
