Just curious how many of you guys are using the factory narrow bands to tune idle and light cruising with Short and Long term fuel trims Vs Using a Wideband in Lambda with EQ ratio?
To me the wideband seems like the better way to go for idle and light cruising as opposed to the narrow bands.
Is there a specific reason to use the narrow bands?
Obviously only a wideband can be used for Power Enrichment as the narrow bands cant.
