I noticed as I was reading the rtek Manual it says it can do wide band monitoring
and it says that there might be slight discrepancies between a wide band gauge
and the rtek readings.

My question is can you run and view the reading directly off
the wide band sensor alone and still be accurate enough to tune?

Or Should you run it with a gauge as well?

This may save me some money on my current build fund but,
I want to do it right not just cheap out.

 

i am stuck with the same ****** dilemma, but unfortunately, you will need a controler (a gauge) before you can connect it to RTEK... otherwise your sensor is useless.

 

Please read the "What you think you know about widebands" sticky.

 

I'll say you do not need a gauge, but you do need a controller. I have a PLX wideband o2 sensor with controller, but no gauge and I log/read all of my WB AFR's on the Palm.

I do have a gauge hooked up to my Narrowband o2 just to see(visual) if a lean condition exists.

 

i ended up getting AEM uego, the whole thing. now i have an extra bosch sensor

 

I have the lc-1 and i run a gauge and also log it through my palm
