so do you have to do anything to the wideband to get it to read in gas afr's like with 14.7 being stoich or do you have to do somthing to the gauge?

soo idk if I'm blind or what, but i still didn't see the answer to the original question.
I get the AFR/ Lambda conversion calculations. Buttttt what is a proper AFR/Lambda ratio?
Am i supposed to convert E85 to Lambda then try and get a "1.0" as WIDEMARIAH said? or is that just an arbitrary number.
Or am i supposed to take the fact rotaries run nicely in the 11.2-11.8 range on gasoline, Convert to Lambda then shoot for the same mixture on E85?
Idk if someone can put it in tuning for retards terms I'd really appreciate it.

or do the afrs stay the same just with 30% more fuel?

if you have your gauge displaying lamba, then you know what to do.
if it's displayig gasoline afrs, leave it alone and shoot for the same. re-read the first page and if you can't figure it out, sell your ****, and get outta the game, all the info is in this thread!

I think everything anybody would want to know about E85 and our cars is contained in this section.
You just have to take the time and read before you ask questions.

well my buddy has a 240sx that he runs on e85. and he said that his tuner had to do somthing 2 the gauge to make it read the same afrs as pump gas thats why i was confused.

Hum? Don't think it matters what kind of car it is.
Anyway...it's OK! I hate it when people say SEARCH to every question somebody asks!

I just fired my car up since it ran on 91. The tune is set for 720/1000 but now Im running 1000s all around. The gauge is reading 14.8 or 1.0 lambda on e85.
