The guys over at eflex fuel are extremely helpful and make sure you have what you need to complete your set up and make sure your vehicle will function properly. I forgot to mention some items in my fuel setup before placing my order and they Called me to make sure I had or was planning to get what I needed prior to installing the kit for it the function properly. They also explained how to go about working around my tune for my turbo build. I would recommend this company to anyone. 10/10 service and quality products!
2017 ram 1500 5.7
Installed their kit on my ram 1500 5.7 and works great. Took me less than an hour to install and haven’t had any issues. Would definitely recommend.
This E85 kit exceeded my expectations! Kudos to a great product.
Installed this kit and have been running E85 for a couple months now. Absolutely love the kit! Every fill-up I will check how the ethanol content has changed through the app, just for fun. Surprisingly, my MPG only dipped by appx 1-1.5MPG between gas and E85, making it much cheaper for me to drive on E85.
I've run many tanks of E85, gas, and mixes of the two, and have zero complaints. I don't think about it, just fill up what's convenient, and that's it. Couldn't be easier to use, performs better than advertised.
Can be installed in around two hours
Can be installed in around two hours. Love the app where you can watch each injector and the ethanol percentage in your fuel. Also, like the ability to change the setting from economy to towing with the app. I haven't used the sport setting yet, looking forward to trying it out soon.
The horse power increase alone makes the eflexfuel a excellent investment & I'm paying almost 1/2 less in fuel costs. I highly recommend it! They also have great customer support.
eFlexFuel is a gamechanger!
Having eFlexFuel on my car has been a gamechanger! I am saving money every time at the pump. The best part is that I can still fill up with unleaded fuel if I am in a place that doesn't have e85. Also, I now own the eFlexFuel technology and when it times to get a new car I can transfer the computer that car and continue to save money. I am very happy with my investment and looking forward to continuing to save.
I was fortunate enough to be in the...
I was fortunate enough to be in the right place and right time. I got my flex fuel module installed in my gas guzzling 2007 Toyota FJ Cruiser which could only take premium. I didn’t drive it as much as i wanted too because of the gas prices. Now that it’s installed i can run Flex Fuel and enjoy this FJ even more. The guys installed it in a short time and we went on a test drive and they showed me how to adjust the performance with the app and i couldn’t be happier. Thank you so much everyone that was involved and a big thanks to Camille.
The kit works great on my 2008 eclipse
The kit works great on my 2008 eclipse GS, I've had it installed for about a month now running e85 and haven't ran into any problems. When I first tried the install I messed up injector polarity and they were nice enough to offer a coupon code for a replacement wiring harness.
The kit works GREAT & the support team
The kit works GREAT & the support team really help out to make sure it gets done correctly
Best customer support great product
Amazing customer support well detailed manual if you read it right the first time I did not but customer service was fully understood my question and replied within a day install was super easy and I do knoticed more power on a naturally asperated v6 3.0 well worth the cash with the price jump in gas.
Awesome product!!! I installed it on my great condition 2003 Dodge Ram 1500 It gave me more power and cheaper gas!! What more can you ask for. Super fast shipping.
Jeeps with eFlexFuel Plus
First bought an eFlexFuel kit and converted my Jeep WK hemi. Worked perfectly why I now bought an additional conversion eFlexFuel kit for my Jeep Wrangler TJ and this also works great.
The best e85 module I have tried yet
The best e85 module I have tried yet. It does everything they said it would do. Very easy to install, although a couple of the injector plugs they sent wouldn't retain the pins from the module and when you try to plug them into the harness the pins would back out so you had to actually hold the back of the wires into the plugs while you were plugging into the harness. Other than that I am impressed, they really did their homework on this and would buy another for my next e85 vehicle project.
I installed on kit on my wife's SUV and was impressed with the low end grunt and greater horsepower that comes with the eFlexFuel product. Bought another SUV and got the same result. Plug and play. The mileage drop is more than offset by the $$$ I'm saving buying 100 octane fuel at $2.59 per gallon.
The eflexfuel plus kit is Amazing!!
The eflexfuel kit is very easy to plug and play. The eflexfuel team also has outstanding customer service If you have any questions or conserns. I got this kit in the first place for the performance benefits mainly, but I have found it to be cheaper to run e85 in California vs 91 octane which is about $4.60 a gallon right now. I love the performance, the price, and e85 is a carbon neutral and renewable fuel source which is great for the environment. Definitely worth the money, it pays for it self with the money you save on gas.
Easy to install and works great
Easy to install and works great. Customer service was great with the questions I had. I'll recommend it.
Great response time through Instagram
Great response time through Instagram. Much easier install than anticipated. My car has a little extra pep and it’s step.
Love this product! Makes driving more enjoyable.
Recently purchased the Plus kit to install onto my SRT Challenger. I immediately feel the difference in performance power when cycling through the different driving modes. One of the best part of the kit is being able to fill up for way less with e85, especially with the increase of these gas prices. Thanks again guys for all your help.
Great products and excellent customer support
This would be my second experience with eFlexFuel and it's been great. The products are well built and their customer service is great. I was contacted by one of their associates through Instagram and it's great to know that there's that personal connection to customers. My vehicles run great and I'm proud to post (which I have) and tag eFlexFuel for the great product they put out.
