Ive got an aem wideband gauge fitted what sort of readings should I be seeing on it at what revs

Thanks

Idling and cruising should be in the 14's and on wide open throttle low 11's depending on if/how it's been mapped

Hmmm. Mines reading mid 14 low 15. And mid 10 low 11. It's been mapped in the past

Mid 14's are fine but into the 15's is running a bit leaner that it should be IMO, the 10's/11's sound fine as its running richer at the top end which is fine, Might be worth getting someone to check the fueling to make sure

It was runnin 11 and mid 14. Till I fitted a decat pipe this morning got a couple of other bits to do then back for a check me thinks

Thanks :-)

With a decat pipe you will need to get the car checked by a mapper.

Don't forget there's a hell of a lot happening between idle/cruise to wot
If you're using it as a guide to see if it's gonna blow up it is of some use
But your afrs are based on revs/load so it's use is limited unless you intend to log all the required data to do a proper check

As a guide 14.7 is the desired cruising AFR and around 11.2 on WOT.

Yes stoich is desired at idle and at various points at the lower end of the scale
And a figure of around 11s at the higher end for various states of tune , high 8s can even be seen on some standard maps
And it's all well and good going with a figure at idle to a wot figure
But like I said there's plenty Inbetween
And even at wot how do you know what load you have unless you are logging
You can go wot in various gears , road conditions
Load is more important than just saying wot
It's ok as a rough afr guide at certain points for a basic check
But for determining a good tune it's not much use
Until a fueling is calculate in rpm/wot as opposed to rpm /g/rev
It's still only a basic indicator

Yeah, but the guy only asked for what readings to look for on his wideband!

Yes you're quite correct he did
We can without a doubt Tell him at the idle /lower end 14.7
But at wot it is a variable 11s are ideal
He says he's had it mapped
How do we know what his map is
How does he know at what point his wot is correct
So how do we know what he should be seeing ?
We can only say what ideally he should be seeing not what he is actually gonna see
The only way to get some solid info is to do some logging
Otherwise you're just guessing

I didn't have it mapped but it has been mapped only wanted a ruff idea as to what end was rich and lean. Once I've finished modding the engine I'll have it up to lateral to get the map checked and adjusted as required
