- - Setting the A/F ratio? (http://nissansilvia.co.uk//showthread.php?t=1974)

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?

The best way to alter the fueling, is to remap the ECU.

Alundra why don't you turn the boost up (if the turbo allows) and see if it reduces to say 11.5:1.

The reason why they run so rich is because they are mapped without an intercooler ie they make it rich to run safe

what make is that gauge mart.does it come with softwear.

it's a VEMS kit, you can get all the vems software free by download
