How To Install A Flex Fuel e85 Conversion Kit In Your Car (DIY)

Learn how to install an eFlexFuel e85 conversion kit aka flex fuel kit in your car. Running on e85 vs gasoline has some benefits like lower fuel prices, more horsepower, and less emissions. It is very simple to install a conversion kit in a compatible car. All you need is to install the flex fuel sensor which goes in-line with the fuel line, then connect some wires to your fuel injectors, and finally plug it all into a piggy-back ECU so it can make adjustments to the fuel injectors. It is that simple to convert your car into a flex fuel car!

Hoping to get back on a more regular video schedule after my move is complete. I have a lot of cars and tools so this isnt an easy one haha... Thanks for the continued support and I hope the videos are helpful!

This guy really got sent Soemthing by a company but he didn’t know enough about it yet to recommend it to us so he tested it for years so he knows he’s not going to give us any wrong information or recommend any bad products. Crazy how much effort this guy puts into videos

[cmac]

I think the most shocking thing in this video is the 5 years later Chris not only still has that crappy Del Sol he bought for $300 but, that it still runs well and looks clean.

[jeremyhinken]

The real-deal longterm testing on this whole kit is phenomenal.

This is probably the best automotive channel on YouTube. Thank you for all your effort!

Hi Chris 3 years ago I buyed my first car for 500$ and I learned how to work on him thanks to you. Two days ago I buyed my dream car Alfa Romeo Giulietta 1.6 jtdm. Thank you so much for all your hard work and fact that you teach us how to do things in our cars..

[julzmuzik]

Your level of safety is off the charts! Very detailed procedures and attention to details

[AwsomeTrollVeko]

I'm a 100% sure that you have a large part of the evolvement of the level of perfection the car community has these days.
I truly appreciate you and the *ART* you are creating with these videos .
thank god for ChrisFix

[iccxqqc]

Your level of doing things correctly is astounding. I’m kind of surprised you didn’t pause to get a degree in engineering to make sure it was engineered correctly. You’re my hero

Trivia: The "cheap car fuel" alternative in most of Europe is LPG, which has similar characteristics as mentioned by you on the E85 (that is, is cheap, has high octane rating which makes it great for high-compression engines, is more environmentally friendly by being made from simpler hydrocarbonates (mostly propane and butane, whereas gasoline is pentan and some higher fractions) but also has a slightly less energy density than classic gasoline which causes slightly higher fuel consumption). It is a gas though, so it needs a separate high-pressure gas tank (usually installed in the trunk or in the place of the spare wheel) and there are no jerry-cans for that, but also is not affected by humidity and tends to mix way better with air (gas/gas vs gas/liquid aerosol), especially at lower ambient temperatures. As for the cost, assuming 3.875 L per 1 US Gallon, and 3.00 PLN as an average price (based on my own observations), 1 US Gallon of LPG would cost ~11.36 PLN, which as of 4th August 2023 is about $2.82.

Chris Fix your Awesome! You are one of my best Mentors, thank you so much.

I just did my first oil change on my dads only car, it was a great experience, I bought the tools, and I cleaned the garage and set up my workstation, I am 14 & going to start flipping some cars and know I will learn a LOT!
But luckily your videos will stay along the way and be my mentor while Im working on them.

Thank you again!

[DaddyDaGuido]

I'm floored that it was that easy to convert to e85. Not only did I not know that you could even do that, but the fact it's literally only sensors amazes me. Same gas tank, same injectors, same engine, same everything. Unreal.

Also excellent video, you really make it look easy. Thank you for being the best car channel on YouTube

THANK YOU CHRIS! Where was this vid when I was trying to install the eFlex kit into my own car? Haha. Lots of comments from people that have not tried eFlexFuel or E85. I researched the heck out of this before getting a kit 1yr ago. I am in the USA and run E85 from the pumps. Here is my experience:

E85 does not cause issues to the fuel system. This was my first concern. There is noticeably more HP/TQ on E85. You can feel the difference when driving, it feels more responsive than when on gas. I also notice my vehicle downshifts less on E85, I think because it is making more torque at driving RPMs.

My MPG are not hugely impacted on E85. Yes, there is some dip, but in my case it is closer to 1-2MPG which makes E85 WAY cheaper to run than gas in my case.

E85 does not cause issues to the fuel system. This was my first concern before I installed. Modern fuel systems are up for the job, there's been quite a bit of research here. There is a reason high HP cars run E85 - even the new Demon 170. I trust the compatibility check Chris mentioned, there is zero reason to think otherwise.

I think that covers it. I don't mind different opinions but I did my research before getting eFlex and have had zero issues, so it's funny seeing the armchair analysts comment without any firsthand use. If anyone has any questions about the kit you can reply here and I will try to get back to you.

Thank you again Chris! This one was a nice surprise.

The first 5 minutes of this video make the best marketing eflex will ever have. A three year test is all the confidence a car owner needs.

[Serkoharp]

I have been driving with eflexfuel conversion kits for years now and over 100 000miles on couple of different vehicles and everything has been working perfect, even in here arctic Finland. Great system!

[ZeroLamaw]

I'm 13 but because i watch your vids i diagnosed my dad's toyota Corolla Altis I'm grateful you make vids

[MikesAMiner]

Just installed this today. Video was perfect and it was very clear. When you slide the cables into the plastic holder and wait for the click sometimes it doesn’t click in if it’s not perfectly straight. Make sure they are straight! Works perfect!

[bkvishal]

3 years for knowing the product! Man you are BUILT different. Appreciate your patience and effort. Thank you.

[jonnathanjawahir]

Damn been a while.... We all know Chris Fix never fails us❤

[thetypicaljoe]

The amount of planning, researching, filming AND editing that these videos require is out of this world and most have no clue or idea! 👏👏👏🏆🏆💪💪💪

[jennamoonchild]

I have same kit on my Mazda MX-3. I live near this company. As a Finn, it is nice to see an automotive product made in Finland. Highly skilled people and quality product!
