E85 and Flex fuel tunes explained!

[@InFamousAlex209]

I was literally just looking into e85 tunes for my 15 gt! Perfect timing!!! I had so many questions and this answers most of them

[@NikeBird57]

Glad someone is willing to take the time and explain all this, thanks a ton 👍🏼

[@I5ZQ8]

Good shit as always!! Feel like im becoming more and more familiar with these 5.0s thanks to you.

[@B_e_n_B_r_e_w_e_r_18]

This video helped a ton, but we just ordered a flex tune and a e85 tune and we are updating so we can relearn the crank but we got ZERO instructions on what to do...luickly I watch all of your shit, but not sure why after $800 Lund didn’t give us anything but the tuner with tunes on it....

[@EEAlpha]

I think this explanation will help me tremendously with an issue I'm having (after mixing a tank). I will run the tank to E, and see if it works. I hadn't thought about the "relearn" by taking the tank to E....been filling up at half a tank. Spot on video. Thanks!

[@manowar5516]

I swear by E85 for flexibility, but I learned over time it's just not that simple on E85 for performance purposes. Thank you again for touching on this topic.

[@str8jktblahblahblah84]

I'm still loving my 18 gt manual! Hit 155 Saturday morning. I need new tires.... only 4k miles on it.... Will be doing some upgrading soon!

[@francetg]

Thanks for the info, extremely helpful. I have a flex fuel tune in my 16 gt, been filling up with ethanol around a 1/4 tank, now I'll let it go a bit lower before I fill up. Thx for your videos.

[@Moosetafaboi]

Any problems running ethanol over the years?

[@francetg]

@Moosetafaboi None. I still have it too. My gas tank did crack, and I had a vct solenoid go bad recently, but not related to e85 that I know of.

[@Moosetafaboi]

I must have asked about this a dozen times, thanks for making a video on this.

[@bryanlara6947]

Thank you for explaining I was trying to understand this

[@SupraDebt]

Thats great to know, i was hoping the FF tune would bump more then that , but i dont think we can run a dedicated e85 Race tune given our best days we have E65 here in Vegas. Usually tests at e60 or so. Guess I'll live with my 91tune

[@tylerjanota7976]

Thomas Clark e60 is still much better than 91. I believe yolo actually made a video about Arizona’s shitty e85 content in the past. So I’m assuming it should be similar for you in Nevada

[@jordanwilson9627]

My ff tune adds about 3-4 degrees of timing. I feel a good power increase and it’s completelu worth the money

[@rich5.08]

This video helped alot learning about the flextune thanks

[@biggravy732]

Alex, I know you hardly have any time what-so-ever to answer questions but maybe you have a quick recommendation for a spark plug for 13 Mustang GT NA, with full bolt ons on e85?

[@matthewskaggs3792]

I run the flex fuel cause our E85 is more like E60, if we had legit E85 then Id run the race tune but even still the car performers wayyyy better than with the 91 tune. I think it took me probably 1-2 tanks before the car had learned what it need to. The log procedures were super simple to do and I think Dakota made minor adjustments and Ive been rocking and rolling since, in any case Ive always had good results with Lund Racings customer service so if I ever have a question its just a simple email.

[@ishowspeed-25]

Is the E85 worth it? I mean I know it will give you more power but I see it drains gas extremely fast. I’m about to tune my FK8 and I’m deciding if I should go with E85

[@acokedupmonkey3762]

Are you talking about Lund specifically or every flex fuel tune. Never have ran a strait e85 tune because like you said, flex is convenient. With that being said, the times I have filled up with 93 I run it pretty much empty before filling up on e85 and every single time it’s a night and day difference. 99% of the time I’m on e85 (tested to range from 75-82) from my race trac gas station. But my question is, would a strait e85 tune have any pros to it for always being on e85 from the pump?

[@Anthony-vr3um]

E85 is life

[@antoniorafaeltoneperna6368]

Hey man can you do a how to video on becoming a tuner and what we should know and learn to be the best tuner possible ?

I am doing a swap into a 67 mustang and will not have to fuel sending unit that will reset the relearn. Is there a way to do this manually, that you know of?

[@race-ist5point0]

So can you have the E-85R tune and the Flex tune?

[@glockmodder]

i noticed a nice difference with my advanced fuel dynamics flex commander on my scatpack its kinda interesting feels like i don't loose so much power when its 100* outside and yes i got it for convenience for sure

[@carlosv.118]

This clears up a lot thank you Alex

[@fread51]

I have been doing some research on this if you have the money go with haltech you have get new tunes all the time or run your tank close to empty if you're going from 93 pump to e85

[@devinnagorski574]

Also curious on thoughts about using methanol instead of ethanol for blending on flex fuel tune for when it's hard to get e85

[@omarespitia63]

I have some questions you might be able to answer .. i have a 2015 mustang gt that i just retuned through bama performance....i have corsa long tubes with corsa extremes exhaust an injen evolution CAI with fords 47 pound injectors and a boomba racing fuel rail...the problem is that when i cold start my check engine light comes on saying multiple cylinders misfire...it some times did this with 93 tune on cold starts but only then...but with the e85 tune it does it during the day if i go for a drive than park it outside for like an hour the check engine comes back on.....i dont know why...

[@brianbiegert3301]

Great info Alex thank you!

[@LOLHoneybadger]

You've sort of touched on this before, but I'm wondering as a tuner/in general, what is your opinion on Fuel Additives meant for increasing octane etc, i.e. Lucas Upper Cylinder & Injector Cleaner? I live in an area where 91 Octane is as high as you can get at gas stations, is it a waste of time to be using that stuff or is it worth it to 'keep the engine happier' in terms of fuel?

[@eagle1_160]

Everytime you say 15 and up, you also include the 2018 ? So the 18 can also run E85 with the stock Injectors?

[@jershelb]

@Supreme Alpha Male I don't think that is correct. I believe you still need injectors with the 15-17. The 18+ has the twin injection and does not require upgraded injectors or pump for e85.

[@mikehughes8023]

jershelb For 2015-2017 you don’t need to upgrade injectors IF you have the stock manifold.

[@franciscoolivas1989]

I have pretty bad gas in my area and I was thinking of going with a flex fuel tune to make up for it, after watching this video would it make sense to have a flex fuel tune for when just normal driving here and there and then get a separate tune for just e85?

[@berninhodrmz1686]

Alex I know this video isn’t about the question I’m about to ask but I was wondering if you might still be able to answer it please. Is it normal/are the coyote 5.0s known to produce a bit of a knock when cold? I’ve noticed mine does that ONLY when cold for like a minute. I live in California and use 10w 30 full synthetic Valvoline oil. I use to put 5w 20 motorcraft but I didn’t like that when I drained it one time it looked like diarrhea. Very watery and thin. I usually do my oil change every 3k miles and have an oil catch can. Its a 15 GT and have 30k miles on it and no mods.

Drove the car for approximately 15 miles with no sudden acceleration and the car drove fine shortly after I would accelerate hard and the car started to hesitate and lose power with a EPC light on the dash it feels like a miss fire.

E85 is all I put in my 2018 5.0 F150, a factory flex fuel capable vehicle. I have a few bolt ons and E85 performance tune (from another well known outfit). My truck runs wayyy better on E85 than it does on 93. E85 is typically 1.80-2.10 a gallon in my area, where as 93 is $3 a gal. I'm not sure why anyone in their right mind would choose to use 93 pump gas over flex fuel. It's not a convenience thing, it's cost snd performance thing.

Umm relearn is 10% fuel increase and only if it sees a need to change unless Lund changes those settings, it doesn’t apply to all tuners. Also ecm 21327 allows for timing changes with more ethanol. I guess you need to Dumb it down for your customers who you say cannot read.

[@travis427svt]

Hmm this video is confusing. My Lund tuner told me that "sometimes" the cars like the Flex tune over the "R" tune. After 3 revisions my 93 tune made 433whp. After a few weeks I went back on Flex 85 and scheduled a dyno session to see if the Flex and R tune really made a difference. Flex made 443whp and 400tq which was expected. The R tune absolutely shit the bed and rolled around in it. Made 437whp. Same dyno.. Same day with idle and slow Rev learn between tunes. So. Needless to say I'm less than impressed with the R/dedicated e85 tune. The car had been through 3 tanks of e85 so it was 100% and tested to be exactly e85. I also have dyno and corresponding dyno logs to back up the data.

[@YDBT4LIFE]

DVL_RJCT 550 if it wasnt logged and spark wasnt maximized then it won't perform. Now. Why didnt you try the e85 tune first then the flex... you tried 1 tune. Got the car hot. Flashed, tried another tune after it. Makes sense why it made slightly less. And also was it a true e85 fuel in the tank or a learned 70 ish% .. if so the e85 tune wont perform well unless it's good and tested e85.

[@travis427svt]

Alejandro Flores The E85 has been consistently testing 85% since about April up here in Pennsylvania (atleast in our area). Both tunes were Logged and sent in. Was told the both looked good and were optimized. And as far as the dyno one before the other yes we did flex first and gave the car sufficient time between runs to cool down with multiple fans running and data from the logs showed coolant and inlet air temp to be very close to each other from run to run. In reality we were not expecting huge gains from flex to R but were surprised it didn't even come close. Any recommendations to get the R up to speed would be greatly appreciated.

[@YDBT4LIFE]

DVL_RJCT 550 no just run the flex. No need to keep messing with it as flex with good logging will do fine. Most other ppl think it's a race tune.

[@travis427svt]

Alejandro Flores yeah I figured I would hold off on anymore looging/revisions until after the cobra Jet/67mm/lu47/dmark cold air install the have a go at both the FF and R tunes again. Thanks for the info.

[@unfiltereddad5126]

Thanks I had it all wrong , I'm getting an e85 and flex tune.

[@joeyofblades]

So it almost sounds like it's not worth going e85 unless you run a dedicated e85 tune. Flex fuel is convenient and you get the cooler temps from running e85 but you won't get nearly as much power from what you're saying.
