2G AFR gauge reading

[Heryst78]

hi guys

I have a question

I have an AEM AFR wideband gauge.
At Idle, my AFR is perfect, 14.5-1 14.7-1 but when I’m riding, I’m at less than 10-1.
Do you know with my AFR is so rich ?

Thanks

Firstly is Gauge! And then its Wideband!

When you say riding? Is it a bike or trike?

If its a car then how you driving it? Is it cruising or you at WOT? A few more details will help.

Are you tuning the car? How?

10 is an okay AFR for WOT. You should probably fix a few things. Boost leak test. Fix leaking vac hoses. Get a tuning device. Fill out your profile. Simple things.

Its ok, I'm just joshing around ,

And if its rich under WOT thats fine, stock its pretty rich, so its safe, if you are adjusting via the ECU or flashing then you can lean it out a bit accordingly,

But if its just stockish don't fear, it is all ok
