Whos running e85?

[HY35F2T]

So whos running e85 on a turbo and car and whats your target afr's? And whats the wideband setup your running/ Picked up a aem wideband and not to sure on all the google answers im getting as far as what afr I should aim for.

Does it read lambda values?

[HY35F2T]

I think so i just ordered it today. Think thats why they sell it with the other faces.

Wide bands just read lambda no matter what. You can then scale it for whatever fuel you are running. But in reality it doesn't matter. You can tune it in just fine no matter what fuel the gauge is set for as long as you know.

Oh and P.S. each car is different the correct way to tune in the fueling is on a dyno where you can actually see how the fueling affects the torque.

With that said just shoot rich with e85... I rarely (almost never) see any benefit in running what you traditionally be considered a tune on the lean side. Even my personal e85 boosted Honda engine still loves some pretty low AFRs and Hondas typically get away with low BSFC.

I am, running aem uego wide band.

[LIL EVO]

.78 - .82

Innovate stuff here. What these guys ^ said.

I run one of these and is faster than a AEM.
With that said normal driving should be 14.7 and WOT 10.8.

And i would suggest some additive with E85 being so "dry" so some ashless 2 cycle oil mixed in will do the trick!

10.8 is a good safe afr to target. 11.5 is when the power really happens, but things can go wrong going that lean especially if you dont test everytime you fill up.

On e85 I've seen torque/power go either way to be honest around that area (from a gas scaled wideband). And FWIW the tuning window is huge on e85. I likely run my car harder than everyone in this thread and I just pull up to the pump and put it in and run about .77 lambda.. So I wouldn't say your car will blow up if you are running .78 lambda (~11.5 gas scaled) and you don't test your e85 all the time.

Again if your not on a dyno you are shooting in the dark. Not saying you can't get a decent street tune on it, but you really don't know what's really happening when you change AFR, or ignition lead, or cam timing, etc. In terms of fueling just shoot rich (especially on e85)

Innovate makes the best Wideband in the business IMO. I've used and installed on customers/ friends vehicles over 15 and have never had one fail. Sensors will fail after a while depending on the fuel you run. With e85 the wot target will be richer then with pump or race gas. In the low to mid 10's is best. Some people say ethanol will corrode aluminum quick but I disagree. It would take a long time for it to corrode to the point of failure. I would suggest to get fuel line that is ethanol compatible, standard stainless braided line will work but the rubber liner will break down over time so it would be cheaper to just get either type 811 or 910 PTFE line. It maybe double the price per foot but you shouldn't ever have to replace it.

ethanol does NOT have the corrosive properties of Methanol... people who say it does are sadly misinformed.

If what i say is true look on HP tuners site just trying to save a piston=)

[BadAzzGTA89]

Also you can run a flex fuel filter?
