Anyone one running a Gauge with sensor inline for realtime monitoring??

If so, which gauge and where are you tapping it in?

I was going to install one but my tuner talked me out of it. Our cars select the tables based on the inferred content, so the actual content is pretty much irrelevant. The only advantage, which is why I’m still considering one, is because I will know the ethanol content from one station to another. I’m just not in a hurry because I just ordered a drum of e98 and plan on running it on the street.

Ok. I hate the mess with testing at the pump. Was doing it for my 300 until I verified the gauge, which shows 10% low, may need to change sensor. 70% on gauge is really 80% verified. I like to see in real time what my level is.

I get it, but then I ask myself, do I really need to know? That’s the point of the flex tune, no manual adjustments needed for different fuels. My tables are set from 93, to e50, to e98.

The Dusterhoff kit comes with a PCM and transmission tune. I know nothing beyond what I read at the web site, but I can't believe it would require one to real time monitor the ethanol content of the fuel. That can vary quite a bit. E85 ethanol content can range from 51% to 83%. Mainly I think the ethanol content is varied to allow for ambient weather conditions, temperature specifically. While E85 (83%) is fine in the heat of the summer come winter E85 (51%) would be loads better...

I understand what Dusterhoff offers.

I wanted to add an external gauge myself to monitor E content, some thing I'm doing now with my 300.

Was looking for people that have added one and how or where they tapped into fuel system.

It's your car but there's nothing wrong with the inferred Flex Fuel tuning. I just finished a FF tune a couple weeks ago and it's pretty accurate on reading the alcohol content.

Started tuning with E30, went to E50 and E80.

This tune will blow the tires offon the downshift after smashing the gas at 80 on the interstate.

But if you wanna add an alcohol sensor, the fuel line adapter goes on the passenger side.

I know there's nothing wrong with it, just like to see where it's at, that's all. Nosy I guess.

U dont need a seperate guage. When u dial in ur E85 tune the factory A/F ratio gauge can be used to estimate the ethanol %.

When idle and cruising speed AFR's are in the 9's ur E85 is 80% or better. As that number rises the ethanol content lowers. Meaning if the AFR number is now 10 ur at 70% or so and as it goes up to say 11 the E85 content is now 60% or lower.

Its pretty accurate.

O, ok. guess it's something I'll adapt to then. Just used to the 300 I guess.
