How to run E85 / Convert your car to E85

In this video I explain all the knowledge I have on E85 conversions. Including:
1. E85 vs Gasoline: How E85 is different from gasoline
2. How to upgrade your fuel system to run E85
3. How to tune your car for E85

This is the best video I’ve seen while doing research on how to convert a vehicle to e85

[@e-dod]

Thanks! Glad it was helpful!

[@ray8380]

I want to convert my 03 Dodge ram 1500 4.7

[@Magnet0730]

Great video straightforward simple to understand I love videos like this because it really is easy to watch no-nonsense just exactly what you need in a video I really think this good stuff

[@e-dod]

Thanks! glad it was helpful

[@screwdajuice]

Awesome video man, very informative. Keep up the great work!

[@donaldhill1401]

I run my 11F-150 on it. Bad mileage but so fun! Warning, it does cause you to have a led foot.

[@BulliKid]

I will be doing e20 mix to keep my fuel system happy

[@e-dod]

shouldn't have any issues with that 👍

[@OutOfOrderMai]

Thanks man, very informative!!!

I'm not a car person at all, but I'm intrested in ethanol as (in some states/countries) you can make your own. Because I have little knowlage of more advanced modern engines, i still have a lot of research, but good video

[@e-dod]

Thanks! Yes, it is super interesting that you can actually make your own fuel and run a combustion engine on it. Especially when you look at how expensive gas is.

[@ampman5357]

Nice presentation! Quick question: do vehicles that burn “flex fuel” have “hardened” valves? I’ve heard the valves are different in flex fuel engines and running such fuel will burn out non-flex fuel valves. Has anyone heard this?

[@e-dod]

Thanks! I never heard of any issues with non hardened valves. But ethanol is more corrosive then gasoline. This corrosive nature mainly causes issues with aluminum gas tanks/fuel lines, but most people report no issues. In theory ethanol should be better for your valves and everything else in the combustion chamber since it burns cooler then gas. I am just presenting what I researched though, I am no expert 😁. If I do some more research and find anything I'll update here though.

I made my 2022 Prius into a flex fuel vehicle, but there was/is no real benefits. Just something I wanted to do for years. I do put E85 into my 3.6l v6 engine my flex fuel minivan has for maximum power. (My priuss are 120 hp combined, ford is 170 hp, but my minivan is 260)

[@genericdude6551]

I put a flex fuel kit on my stock 2002 Mustang GT. It ran fine for several days on 44% ethanol content but the day that I refilled the tank I got 61% ethanol content (a mix between 44% and 85% which would make it around 61%) and the car died. This is less than a week after I put in the kit. Turns out that it killed my fuel pump (or was it coincidence?) and I have to replace it. The manufacturer and another youtuber said that neither the fuel pump nor the fuel injectors need to be upgraded from stock. Anyway, I ordered a fuel pump certified for E85 only to find out that the fuel pump housing for the bad pump was of poor design where you have to remove a small hose to get access to the fuel pump. Which caused another problem because I ended up destroying the small hose and can't find a replacement that is SAE 30R10 anywhere. The corrugated hose fits onto an 1/8 inch OD port on each end of the assembly. So, I have to order a complete assembly with a fuel pump pre-installed because you can't get just the housing from any manufacturer. You might not be able to specify an E85 compatible fuel pump either. I'm not a happy junior mechanic right now.

[@e-dod]

LMR has some options with an upgraded pump installed such as: lmr.com/item/LRS-9350E/1998-04-Mustang-255-Lph-Walbro-Gss342-Fuel-Pump

[@matthewmoore661]

Well done. Only question(s) not answered: conversion cost and do the fuel system materials type have to be changed?

[@e-dod]

Great question, I should have mentioned this. The reason I did not include that is because it varies by car. For example, I have a Lancer EVO and it has been running E85 for years on stock fuel lines. Just has upgraded pump & injectors to support the additional fuel needed. But, I have heard others saying they needed to upgrade to PTFE AN lines because the E85 corroded their stock lines. So if you can find some info for your specific car that would be best. Otherwise, try it out with stock lines if you are on a budget and just keep an eye on things. Most cars have metal lines under the chassis so you would mainly want to keep an eye on the engine bay since leaky fuel from corroded lines + hot engine bay not good. Let me know if you have any other questions, thanks!

[@henrie.c]

@@e-dod just the answer I was looking for, glad I looked through the comments first. Also, this was the best explanation video I found after watching two others, third definitely was the charm!! Lol

[@therealpower622]

Ok so can I run only e85 with absolutely no mix? I have my car tuned to e85 also

[@e-dod]

Definitely can. The only downside is if you use pump e85 since it can vary and is usually not 85% ethanol. But ethanol itself is a forgiving fuel so usually some variance will not cause any damage to your engine even if its not ideal for performance or gas mileage.

[@williambixby3785]

No much info out there on stuff like this… do you think you may do a video on vehicles that run carbs or have a resource I can look at?

[@e-dod]

You would just need to make sure your fuel system can support 30% more fuel and jet the carb to run the 9:1 ratio that E85 needs, but the corrosive natures of E85 might be troublesome with a carburetor.

[@indiobaez3314]

Hey Thanks For The Video, What Should My A/F Ration Be On Idle On E85? I think 8.9 Is Too Rich On My Kswapped Civic

[@e-dod]

Hey, thanks for watching! 8.9 definitely sounds to rich at idle assuming you have 85% ethanol or lower. Should be closer to 9.8 at idle if you have stock/mild cams.

[@indiobaez3314]

@@e-dod Thanks For Getting Back To Me I Have A Stock K20z1 With Full Bolt On I'm Usually At 10.20-11.00 A/F Cold Start Is 9.8

[@e-dod]

@@indiobaez3314 np, cold start will need to be richer. it should lean out gradually as car warms up. This is normal for a properly tuned engine. Also, if you are running a flex fuel sensor and your ECU is properly tuned for flex fuel then your AFR's will vary based on the ethanol percentage. So for me to advise a target AFR you would need to let me know what percentage your E85 is as well.

[@ray8380]

Does anyone know how would i go in tuning my ECU im new to this thanks in advance

[@e-dod]

Find a tuner or check out HP Academy to learn how to do it yourself.

[@magnusjahn5342]

how far you are in progress? looking forward to it!

[@e-dod]

Getting the Civic back up and running before any e85 activities :)

[@Shreddylife]

Noob question, I am thinking about converting my Boosted D16z6 Honda to E85. Would I have to get the engine retuned?

[@e-dod]

Yes, you would need a re-tune so that the engine is given more fuel. Also, if you have a good tuner that knows how to tune for e85 he can lean out the AFR's, increase boost and increase timing with e85 so you make more power.

[@Shreddylife]

@@e-dod Thanks, I kinda figured. Speedfactory would be the ones doing the tune so I am in good hands

[@e-dod]

@@Shreddylife Perfect! They will know exactly what to do. Should be a lot more fun on E85 😈

[@jrgonzalez5781]

We just want to see a video where you're putting parts and explainin

[@e-dod]

Hopefully will have one soon

[@MirAqueelAli]

thanks

[@fliside1102]

Can this be done in the f150 5.4l

[@e-dod]

As long as you upgrade the fuel system. You would also need to find a way to tune the truck to provide more fuel.

[@emanuelvasquez1897]

I'm driving a f250 that use e85 and in reality it's way slower then using regular gas

[@e-dod]

Is this an OEM flex fuel vehicle? Maybe Ford intentionally made the tune conservative to result in better gas mileage since e85 requires much more fuel burned then gas? e85 itself only makes the car faster if the tune takes advantage of the higher octane and cooling capabilities e85 provides.

[@bonilla55us]

How much would it be to convert my 2009 Honda

[@e-dod]

Is your car stock?

[@robertd6925]

3:10 so that explains the shitty mpg drop

[@Indi_DevJames]

I don't trust myself lmao maybe after the first 6 engines I toast il get the hang of it

[@e-dod]

Better find some cheap engines lol

[@Indi_DevJames]

@E-Dod haha your not kidding 😂 I'm gonna go ahead and wing it with my mazda rx8 if it goes bad il just buy more used parts and sell the old ones as furniture haha

[@brandoncody85]

"Eatey 5"
