I’m losing my marbles-

what is the leftmost small gauge measuring and why is it below minimum measure both at rest and underway. Only way i could briefly see any value was at speed and then lift off the gas pedal and allow car to coast in gear.

Air fuel ratio!
I’m guessing my new E85 tune is what has it running much leaner than the 14.7:1 considered ideal for pure gas?

stoichiometric ratio for E85 is 9.7:1
It’s much richer than gasoline stoich.

What my friend Cory said above! That gauge is unfortunately useless now in that form due to not reading below 10. Find another one to add to the trio!

Whoops yup, my mistake. It’s below the low point of the gauge. Richer not leaner. Mo’ Powa!

Correct. On screen real time display
Cool. I’ll check it to see if my gen3 2021 has the same.
candidly, I’m pretty much at a loss to decide how I want to set up my digital dash. The speedo and tach are about all I pay attention too. I suppose I need to have the engine temp but all the other choices are a bit mind numbing for a street driven weekend toy.

Your ‘21 will have that. My ‘22 does as well.
