Setting the A/F ratio?

[30psi]

If it dont have a wideband lambda its almost useless.

What does it show on boost?

As I said, 14.4 14.5 area at idle go to 10 at full throttle.

Don't remember that car which have lambda sensor narrow are sufficent for stock engine management specially with MAF, it isn't so useless like our security dump security valve.

I'll take a video

a narrow band sensor works completely different to a wideband. your gauge is lying to you

Alundra, what the guys are say is that the stock lambda sensor will be fine for you ECU and general running of the car, but when connected to the A/F meter it will give you a false reading.

you prolly are getting a reading on the gauge of 10 on boost, but that figure will be false.

Ok! Thanks sideways
But I don't know why?
So added oil gauges are false too?
I don't know the term in electronic in english but the A/F meter was fitted "en parallèle" not "en série".
That means it can't perturb the reading of ECU of the lambda.
So video is useless.

P.S: Finally if I understood! Be reading some stuff on net narrow sensor is useless for monitoring! Perhaps i run stoechio or lean and i don't see it!!! Sorry guys i misundertood you, to be clear adding gauge on a narrow sensor only show you that your ECU adding or not some fuel, but you can't see if the mix after it is stoechio or not.

Wideband sensor + gauge for reading it is very expensive!

Can a wideband sensor can be fit on a narrow sensor gauge?

So SAFC without wideband is useless...

Back from the start of topic: Anyone have a gauge for detonation monitoring on our car?
