What is this gauge ?

[Fender5803]

I've tried to find what the lower gauge is telling me but just can't find any info ...
Thanks

I believe that’s air/fuel ratio

If that’s the air/fuel gauge should anyone need to know what the normal gauge should we be expecting from it? And what is not normal? Let us all know! Thanks!

Maybe reading this article will help

The correct answer is "it depends". Are you at idle? Are you coasting? Are you doing WOT? Are you cruising? Each of those will have a different answer for what you should see as "normal" on the AFR.

The link above is a good explanation of what you are looking for.

So what’s abnormal then? Lol! Guess I’ll double check if manual for info if it is there for clarification soon! Thanks!

So it's the ratio of air to fuel, thank you for the article Allanrock59 !
Still. I wonder what the symbols are Ford used ?
They look like hieroglyphics. Maybe the Greek letters for air and fuel

it's 3 icons together. the top is an arrow, with the stem being funneled in, likely to represent air being funneled into the intake. the middle is a slash, to represent division. the bottom is a beaker of some kind partially filled with a liquid, in this case safe to assume fuel. the order of the icons makes sense because air fuel ratio = air mass divided by fuel mass

Owners Manual, pg. 408 discusses Auxiliary gauges:
• Cylinder head temperature. • Engine oil temperature. • Transmission oil temperature. • Axle temperature. • Engine oil pressure. • Inlet air temperature. • Manifold charge temperature. • Intercooler coolant temperature. • Vacuum or vacuum/boost. • Voltage. Note, depending on your vehicle configuration, not all gauges are available.

Dang. So glad ford thought to add that. Especially great for the customers who mod - namely supercharging.

Anybody know if there is a boost guage in the new system? Especially since Ford is trying to corner the FI aftermarket with whipple.

Unlikely to find a boost gauge in a normally aspirated engine. The percentage of Mustang owners who add a SC is extremely small.

that’s a shame. Ford is forcing customers to go through them in order to boost and so should have provided that very easily in the digital dash as part of the tune package with a hardware sensor and receptacle built in the ECU if needed. Someone at Ford didn’t think that through.

Especially strange since some deslers offer a dealership package with the suer charger installed under warranty.

weird. Hopefully they fix that problem soon.

See the thread about how to enable it with forscan. It adds functionality to the intake vacuum gauge

looked it up seems the thread ends inconclusively?

edit: found the OTHER thread on the subject. lol. Seems you can indeed get a rudimentary text readout going. At least there’s something?

but far short of what it should be.

although I have the digital values on my dash display, numbers on the gauge display would be an improvement, one of very complaints. My 5.0 in Normal running is around 14 and 20 when coasting in gear. does the above link to the air/fuel article imply the ratio changes in Sport or Track modes?

Perfectly said ... I did get the division slash
