Wideband A/F for newbies


Recommended Posts

Ok…totally new to the turbo scene. Installing a turbo kit in my 2000 Suburban 5.3 - question is this. 
I’m ordering a pillar gauge pod with boost gauge and a Wideband A/F

do I need a separate Wideband for E85 ? I do plan on running E85 more than high octane gasoline. Should I buy two separate gauges??

I believe that you can choose what fuel you are running on the gauge with the different modes but I cannot remember

 

It doesn't particularly matter though, you just have to remember that stoich at e85 is like 10? and stoich for gas is 14 or 14.7. The wideband is just going to show you the numbers.

I don’t know if you can particularly choose the fuel but your right you can use your lambda reading mode on your wb to adjust your stoich to the correct fuel the person is using.Lambda is the way to go.
