A/F install questions
I bought a A/F gauge today and I have searched and searched for a right up for an S4 and have not found one.:scratch:
Any suggestions on how to wire it to (or which) O2 sensor and the ECU wire? I can do the rest just need those two. Thanks guys.:icon_tup: |
What gauge did you buy? the autometer or a wide band? If its got that one purple wire, I think thats what it is universally to them gauges. It should go to the o2 sensor closest to the engine it should only be a single wire o2.
|
Its a Sunpro 10 light. Has Red for power, Black for block ground, Green for O2 wire after connection (thats how itt is shown in the diagram), and White to lights.
|
I only assume you have a narrow band gauge. Just splice it with the stock o2 sensor. If it's a wideband, you have instructions. Also it's usually a green wire on narrow bands.

any mounting ares that wont mess up something else?

So It is installed and works.
Is it normal for it to bounce from good to nothing to good again rapidly? Happens when I am driving on the highway. When I stay at a constant speed it will bounce faster. The onl I can get it to stop the bouncing is to give it more gas while driving. Any thoughts? |
yes thats normal if its boucing on the highway.
Its in closed loop mode. If you are at steady throttle, it will do that |
