Default AEM UEGO with gauge question

I want to purchase a 6 in 1 gauge type AEM UEGO.
But how bright and readable is the display? It seems to be very small (apx. 10x15mm according to photo).
I like gauge type display vs. box type like m300. And AEM 6 in 1 is quite cheap at the mo.

So any experience with AEM WBO2 gauge display?

I have installed it yesterday.

Display is better than I expected. Red numbers are readable in sunshine.

The only problem is the shown AFR. It is different to the logged one. 0-5V output voltage value is 0.6:1 AFR less than the one shown on display. I have no idea which one is correct and which one is fake.

I read on AEMPower forum this is common case. but noone received exact answer from AEM yet. Tips only (change to another ground source aso.).
Has anyone experience with this AEM Gauge? Which value is real? Displayed or logged?

In case i get no answer, i try to borrow another type/brand WBO2 and install that to compare the values. Though it'd easier to be told which value is real

unless you have an ECU capable of handleing the 5V input then you really shouldnt be logging with it set to P0... change it to setting P3, that mimics a 0-1V analog output for datalogging and is actualy safe for ecu's not setup to take 5V in

I know the ECU reads max. 3.82V (17.78:1 AFR) w/o modifying it, but why is it bad if I use 0-5V output? When the mixture is very lean (above 3.82V), this 3.82V threshold is used. I never go such lean when driving (unless i pull my leg from pedal).

Autronic 0-1V wideband emulation has tightened scale thus values more rounded IMO.

the settings dont have a very big if any varience in AFR readings, i've used them all and there the same
