Ideal a/f ratio e85 nitrous

[Nhra747]

What ideal/safe a/f ratio should I be looking for on my wide and on a e85 nitrous car? Same as pump gas or does the a/f read richer?
Thanks

Does your Wideband gauge display in Gas AFR, E85 AFR, or Lambda?

Thanks,

Gas afr I believe
It's a Plx device wideband

I would tune it for 12.0 to 12.5 at WOT.
