DIY Visconti Flex Fuel kit for E85

[Yruyur]

You are correct.

Yep. The ethanol content analyzer is sending EC levels to the ECU many, many times a second. This can be verified using the ECUtek software. Pretty cool to watch -- down to the hundredth of a percentage.

That's how you get away with indiscriminate fueling. E85, 93, it doesn't matter. Just put it in.

Just finished installing most of the kit here, just have to run power and ground at this point. I wanted to point out that for the ECU portion. You can disconnect the two 10mm bolts there and the main ECU assembly will come free allowing for slightly easier access to those tricky plugs.

Thanks for the info, we'll try to detail that in the video install guide coming soon.

Where did you tap into 12v for power? I have all of the cabling done except for 12v power. I can't wait to fire it up!

I ended up tapping into the radio fuse in the fuse box for 12v and used one of the bolts behind the kickpanel for ground. I just flashed the tune, so as soon as the ECU is done doing some learning, I'm heading out to grab some E85! Sure, it may be nearly 2:30am and I have to be up in a few hours for work, but this is much more important right now!

Hey I wanna see this when you get it running.

It's up and running now.

Finally got back home just after 3am after filling up with some E85. There's only 2 stations around me that carry it and of course the first one was closed. I put in 3 gallons of E85 just after my fuel light came on and then topped it off with 93 octane. By the time I got back home I was running right at E30. I thought it would be higher than that, but I suspect that the ethanol content of the E85 that I got was lower since the sign on the pump stated that it had a minimum ethanol content of 51%. I'm going to try the other station and see if it has a higher percentage.

The car with this tune runs absolutely fantastic! I can definitely feel more torque in the lower RPMs and it just seems to have more power all around...and that's before I even added the E85! @Visconti thanks for yet another amazing tune, I can't wait to see how it runs on pure E85!

It really is a great tune. I noticed the same thing you noticed... even on pump gas, it feels better all around.

Congrats on the install! Now, do some logging and send it over to John.

I plan on doing some logging tonight, although I don't know how useful it will be since I'm running STG2 without a header and I don't want to waste John's time. I thought that my P&L header would've been here by the time I got the tune, but no dice. Hopefully it'll come in next week so that I can see what kind of difference that makes. I'll be out of town until next Monday anyways, so I suppose a bit more waiting won't kill me, although I'm really going to miss driving my car until then!

I haven't heard of this either. Do you have a source thread where this is discussed?

It's all speculation for now. Until we get more miles on more filters we won't know for sure that E85 is causing this.

Basically it was one person who experienced a problem after putting extensive track miles on the car and there was absolutely no definitive proof that running E85 was the cause. Many, many other people are running E85 with no issues at all.

What would a reasonable amount be to pay someone to install it the kit? Seems a little daunting to me...
