hey so I was thinking since I plan a 93/e85 tune what wideband should I use ? I have a aem wideband for 93 octane gas right now so would I need to switch it out to something else? thanks again guys for helping..
You don't need a new wideband if you already have one. The sensor can't tell what fuel is being burned. You just need to know what A/F is your target in a Gasoline scale and you will be fine.
Isn't the ideal A/F for E85 somewhere in the 9's at WOT?
When KEVIN tuned mine we were still aiming for 11.5 - 12 on E. Guessing he scales it differently on his end.

Ok. I think I misunderstood it. It sounds like even with E85 it'll show 11.5ish on the wideband if it's set up for gas.
I think I would have to get a different gauge to be able to show Lambda. I have a PLX module and an Aeroforce gauge for the display.All gauges read in lambda 1.0 being stoich then multiply by a fuel scalar. So if you dont change the fuel multiplier it'll still display gas values even on e85. That's why most people who tune and myself have it just display in lambda. That way you're just using the raw data and dont have to worry about what's in the tank (AFR wise obviously matters in other areas).
