Narrowband O2 sensors?

[Bussey]

Are these completly useless? Looking at buying some gauges that are all matching and I think the AFR gauge is just the type that splices into the stock lambda feed, a few sites are saying that the readings on WOT are useless? I don't see how this can be true though surely.

Lambda is only used for certain rpm, cruising etc. then map sensor takes over. Thats what ive read before anyway

[gorganl2000]

yeah, they are just pretty lights

useless for tuning

you need a proper wide band sensor/kit if you want to do it properly

[Bussey]

Yeah I though just as much, would there be any way of wiring up an AFR gauge to a completely separate wideband lambda? Surely it would just be a case of changing the signal wire over? Sort of had my mind set on the gauges I want now.

For an air fuel ratio gauge u NEED a 5 wire bosch WIDEBAND sensor.

thats the only option.

However you can use a feed from the bosch wideband to power your cars standard single wire lambda feed to ECU.

but it gives a later signal as its further away than the bosch wideband by 40+ inches.

in my opinion only ever use the single wire standard lambda for the normal ecu feed and keep the wideband bosch totally seperate
