Just trying to fit in with some sort of gauge in my vent and since I don't have a turbo, I went with an air fuel ratio meter. I think it fits in nicely with the A4's lightint scheme. Opinions welcome.

How much did that run?
I've heard really bad things about a lot of the cheaper gauges(under ~$300) were it was displaying rich but really was running lean).

Cheaper (narrow band) A/F gauges don't have a very good reaction time. I am currently running one and all it is really good for is sustained WOT. If I am really on the gas for a while, I want to see it in the RICH - but it really is not good at all for tuning.

This is all moot since it's basically bling on a V6 [;)] - but hey - it's little more than bling on a 1.8 unless its a wideband...

well since you're not turbo, and it doesn't matter much, enjoy the light show!

Narrow or wide band setup?

It was cheap and it's a narrow band setup and I'll agree that it's not a very useful tool. But, I am aquiring some of Mance's intake parts and wanted to watch things before and after I install them

well in that case it wont be much of a light show anyway since the NA cars will just tend to run at 14.7:1 at wot. Not exactly worth doing in a NA unless the car doesn't come with a Maf.


jbrentd - adding a intake isn't going to change the AFR on your car, the ecu will adjust for the change in maf readings and IAT's. Bolt on parts only change the AFR on a car like a honda that doesn't use a maf to adjust fuel maps.

haha true...on a N/A car, the tuning for more power phase is the only time you really need to see a/f.

When did the oem sensors change to wideband?
