DIY: The All-New BM3 Flex Fuel Kit by ProTuning Freaks | F80 M3 Install

[@gavinjohns3362]

I would highly recommend wrapping the fuel line in the microfiber towel when taking it off 😂, mine just sprayed everywhere even after starting the car, hopefully this helps someone.

[@SILENTJRM]

Glad to hear that the F30 install should be just as similar and simple to do!

[@prayformojo1117]

@Metro Should be under OTS Maps if your car is compatible.

[@kaiichinose9590]

Flex fuel is the truth I had this done on my f87 m2 og lci. Best mod ever. All fueling solved. I make 540whp on 93 and 660whp on e50. One tune to rule them all.

[@Zurnimal]

Great video Bryan! I've got a 2015 335i M Sport. If I want to do this to run an E85 blend, do I need to upgrade the fuel lines, lpfp or hpfp to make this work?

A stick n55 fuel pump can handle up to e30, and higher could crash the fuel pump

[@ethaninocando]

Hey kies, a lot of people have questions about this kit for n55s. You should make a video explaining the limitations and benefits of this kit for the n55.

[@ufcgoonz986]

@ImFunneh I just installed this on my M235i... install was easy... good kit to tell how much E85 I am running. Will need to flash one of the flex fuel maps to benefit from flex fuel.

[@miahh1504]

Thanks for yet another awesome video Bryan. 🤘

[@hyde_official]

nice! I love clean DIY like these. Hustle free

[@bimmerboi_hutch]

love the videos, but not necessary to reflash at the fuel pump when switching back from 93 to e50 or e30 back to 93....just don't run crazy with it until you flash it. i.e. change fuel, drive easily home, don't wot at every light, or just don't go wot at all, once your home you can flash. that said, i do want this sensor ;)

[@Svall23]

so what i’m understanding, even tho i don’t have a custom e85 tune, i can just buy this and run 100% e85?

[@JPMichaels2010]

I think you'll need a flex fuel tune.

[@Svall23]

@@JPMichaels2010 did more research and found out you do not need a custom tune, although a custom tune would be better obviously, the ots map has tables for all e contents!

[@gixxerhoff7502]

@@Svall23 thanks this is what I wanted to know

[@mariomunoz7167]

On what platform? Be specific, man. N55? You’ll need to upgrade the hpfp and the lpfp at anything above e30 from what I understand. The Dorch Stage 2 for example, allows for full e85. Although, the lpfp won’t support anything past e30- so you’ll have to upgrade that. S55? I dunno.

[@MrDC204]

Where did you find this info, I have just bought one and I’m struggling to find what I need to know.

[@bimmerboi_hutch]

Rear backseat is a major pita! I've struggled several times with it! Couple of additional questions: 1. For the ethanol reader, will previously made custom maps still work? I have tunes with both Paul and Cary -- curious if I can add them as options for maps 1-4 for the on-the-fly map changes? or is a new custom map required for this functionality? 2. You do a good job of showing how features work - I'm wondering if you can do a video for the anti-rolling lag. I can't seem to get it to work, and there's not much content out there on how to properly use this feature! Thanks @Kies!

I also have a question on the spark plugs. Im running a stage 2 OTS tune atm and am already running a step colder for this tune. Do i need to go another step colder for the BM3 kit or are the existing plugs (which are already 1step colder) be ok? Thanks!

[@claudioagmfilho]

🇧🇷🇧🇷🇧🇷🇧🇷👏🏻👏🏻, Great vídeo Bryan, awesome bit of kit. I think that ethanol in a way is much better for your car’s engine, it burns cleaner, it burns cooler, it cleans the engine on the inside, even the engine oil takes longer to go bad, oh, and it has a higher octanage. Gasoline just clogs up your engine inside and what not. Don’t take me wrong tho, it does lubricate some parts of your engine so, it is also needed sometimes. But I usually use 5 full tanks of flex fuel, say E85, and one tank of 95 octane gasoline, after all these cars were made mostly to run on gasoline, and not on ethanol blends. The one thing we got to watch out for is that the higher pressure fuel pumps and the lower pressure fuel pump make take a direct hit whilst using ethanol blends.

[@cgkperformance]

So can the stock fuel system cope with e85? I was always under the impression pumps would need upgrading.

[@Fckbmw]

Right I’m confused

[@cgkperformance]

@@Fckbmw it'd be nice to get an answer.

[@jacobbloom5931]

An n55 stock fuel pump can handle up to and e30, I won’t go higher then e30

[@ghettobutter]

I'm also wondering the same thing although I know Carry Jordan (custom tuner) has full e85 tunes on stock fueling system for the s55 platform. Bootmod3 doesn't make it clear atleast from what i can tell just says full flex fuel???

[@MikeyG003]

S55 can handle full e85 and anything in between on stock fuel system. N55 is limited I believe

[@lilstunna14]

Would you need a hpfp with this kit!?

[@dwembree]

Hey Bryan - what do you think about the need, or benefit, of additional filtration?

[@TheFanatic340]

Not needed

[@jmciver767]

I am interested in this as well. When researching this type of mod I learned that ethanol has solvent properties that can release built up gunk in the fuel tank (and even fuel lines) from years of standard unleaded gas use. This released “gunk” can lead to clogged fuel injector problems that have been reported by some who have done this mod on cars with higher mileage, hence the recommendation by some to use filtration. Otherwise, I love the simplicity of this implementation.

[@prayformojo1117]

@@jmciver767 Maybe, but if you're running injector cleaner regularly and using top tier fuels I bet its not widespread.

The flex tune would automatically adjust the tune for the fuel.

[@davis7323]

Good video, but isn't the point of this install, is to run ethanol maps? And correct me if I'm wrong, F body m3/m4 can run full e85. but in situations where you can't find e85 or you can't run your tank down to empty. This will allow you to fill it up with 93 without need for calculating what %ethanol u have and your map will adjust automstically for the ethanol content? So its a convenience mod?

[@AyoRafy]

what if im running like e30 and then I switch back to 91 do I have to switch maps or can I leave it on the 93? im in cali

[@owencozine5581]

how do you configure burbles in the multi map stage 2 OTS map

[@chrisgarret3285]

let me ask this, I've just recently switched to the E-20 Stage 2 Plus MHD map on my FBO 2015 335i. I've been targeting either E-30 or E-28 in my calculations cause I heard that sometimes pump gas is below 10% (I've been testing the flex fuel with test kit and getting the claimed E-83 for the summer blend). If it ok to run E-28 on a E-20 map? Seems to run great but I do worry.

[@dougcoffey3496]

You’ll be relatively safe to go over it as long as your fuel system can handle it. I often run E40 on my E30 tune, and when I run the 93 tune I mix a couple gallons of ethanol in because I get a lot of timing corrections if I don’t

[@KevinMO91]

I was about to get a Flexfuel kit for my 2022 M3 xdrive, but its just a wireless bluetooth reading from what I gather. Should I just wait for a solution like this? I'm still waiting on actual dedicated tuning. I been running JB4 for a bit now and am dying for a tune.

[@b58_moe]

is there a app where i can check my ethanol level for the bm3 flex kit?

[@cokemachine62590]

1) How does custom-rom work with an already installed custom E85 tune? 2) That's gonna take the average person way longer than 5 minutes, especially with reinstallation. Hell, it took you 10 minutes and that was with cuts/edits lol 3) There's no way you'll convince me that the connection at the LPFP or the little module you tucked away against the body of the car won't rattle. These cars already rattle in stock form, not to mention adding aftermarket exhaust to the car lol

[@infre1400]

1) I'd imagine if you already have an e85 tune, you already have supported mods to calculate your mix, this system does it for you and works off your "flex fuel tune" to get you to the right mix for the tune so the user doesn't need to sit and calculate, rather than pump and go. 2) Took me about 20 min, watched the video 3 times, getting the back seat in was the hardest. 3)There is a pretty decent gap between the side leather piece and right under the headrest which I tucked mine into, and ziptied it, zero issues so far.

[@cokemachine62590]

@@infre1400 That’s what I mean though, does the converted Flex tune from a custom map work correctly? Or do you need to request a new “flex tune” custom map from your tuner? Speaking of rattles, there’s no rattles coming from the tiny compartment at the LPFP?

[@chuco425]

How can I be sure to get it before they sell out? Lol tired of having to estimate an E30 blend in my M235i all while hoping the E85 I’m putting in has ~75% ethanol (some stations have as low as 50%).
