Normal range for a AFR gauge is 10 to 17.

I cant speak specifically to your gauge.

You will have to run a relay to have the Koso X2 to power when the headlights turn on... or put a switch in the power. The Koso X2 on a Viper will not read the O2 sensor correctly if its turned on with the ignition or at the same time the sleds starts... it will give errors and false 02 readings.

It goes from 10 to 24:1. The info is here.

Is this the case with other Koso gauges as well?

I am not sure what you are asking... the range is correct.

The X2 is the one that I am familiar with... I have no idea on the others.

Oh really , relay ?? I called them up because the gauge wasn't working and they told me to ground on frame and use ignition from key switch .

You can do what you want but I found it's the only way to get the gauge to work properly I even called them and told them about it and they seem to blow me off after while.

no no I appreciate all your info , like I said new to this turbo stuff and don't want to damage my motor .

Hey guys , well went out for a rip Friday and noticed that afr was reading 14:9 15:2 at 4200 rpm 3 psi of boost when I hit the throttle went to 12:2 and 8 psi warning light came on boost went down at 5.5 a sec. later . yesterday had to take the sled out of garage heated garage for a few hrs. wen it came time to brung it back inside wouldn't stay idle unless I would give her a little throttle . ????

Is this your first ride on it? It will read higher at low boost just putting around thru the woods... drop the green lower.... how long does it stay at those numbers at low RPM?
when you blow out the track it will spike the boost but as long as it doesn't stay there after a few seconds your fine.

No it's not my first ride just started to lean out , I'm starting to think bad gas . gased up at a old service station and maybe it wasn't supreme gas

My worry is wen cold doesn't stay idle
