[@yyzgsxr]

Was going to have this installed by a shop just to save time but it doesn't make sense with how straight forward everything is...Great job guys once again!

[@AGBoost]

One of the best flex fuel install videos for B58 cars out there. Great work on this.

[@MisterSkizzels]

Yeah baby! Now just waiting for my DME to come back from Femto with the new B58 CustomROM on it! Thank you for your great work guys!

[@protuningfreaks]

🙏

[@JohnUnnever]

Got mine installed yesterday - this video was super helpful!! No issues and got my e85 blended in running at e50 according to the in-dash content reading (which is very cool). Thank you much!

[@protuningfreaks]

Awesome! Great to hear! 🙌

[@Teems-o9h]

Are you running on the multimap with flex enabled? Have you ran any logs to see if the MM offers the same or more timing than a dedicated E30 map?

[@yguncho4371]

I got question. does stock gen 2 hplp works with this flex fuel kit? would u recommend to run full e85? or those it need to be blend?

[@protuningfreaks]

@@yguncho4371 you can run any ots map on the stock hpfp

[@suprasupra718]

I'm late to the party here few question if u dnt mind ? Trying to run e50 blend my self going to order bm3 fuel kit , what tine u running

[@braxtonrosas7338]

Hey y’all, there isn’t a single person on KZbin who has shown the flash process on the f56 mini Cooper platform (2014+) BM3 is THE ONLY at home flash option that is not a piggyback and doesn’t require sending the ecu out. I would love to see an install video out there. I am working on convincing my girl to let me tune hers, and also for my own knowledge. Thanks!

[@protuningfreaks]

We can try cover it in a future episode but the flash process and overall use of the app on Mini vehicles is completely identical to any other car flashed with bootmod3.

[@haichau7631]

After installed the bm3 kit how do you know how much ethanol do you have?

[@kevinp645]

Do you must have CustomROM to use flex kit ?

[@isanmoldonado4587]

Is there a difference between this and the Visconti flex fuel ? I’d like to get bm3 tuned on my Supra so curious if it’ll be any better

[@protuningfreaks]

For a description on our kit you can refer to our website. Our flex fuel kit has a beautiful machined housing for the flex fuel sensor which has a built-in fuel bypass to avoid adding a restriction imposed by inserting a flex fuel sensor right into the fuel line of an already limited factory fuel system.

[@Teems-o9h]

I just bought this kit and will be installing it this week. Do you have plans for a Multimap that has slots 2/3 with e30/e50 maps?

[@protuningfreaks]

The magic of a flex fuel setup is that you don’t need a fixed ethanol percentage map slot. The Multimap has flex fuel built in and will transition from 0-100% ethanol on its own.

[@Teems-o9h]

Performance of the multimap with flex enabled will be the same of a fixed E30 map?

[@derekm2317]

Are these the correct instructions and the proper kit for a stock 2020 X3M Comp?

[@protuningfreaks]

Yes but you can always email [e-mail] for any help

[@robinbanks3288]

Will this work with the B46/48 in the 3rd gen Minis?

[@protuningfreaks]

You’d need to contact [e-mail] to check

[@nhg167]

Is e50 safe on stock fuel system?

[@protuningfreaks]

Yes

[@nhg167]

Sweet & thanks for the fast shipping!

[@floydboyce274]

I don’t know if to get fuel hat kit or engine bay kit decisions !

[@protuningfreaks]

If you have a modified fuel hat then you need the engine bay kit, if not then go with the fuel hat location

[@Slowww_F30]

So I’ve tried searching online to see if it does work but I can’t find an answer. I have a 2013 F30 with the N26 will this work? I’m stage 2 e30 and FBO but I’ve tried to look for a kit that works on my car but they usually only say N55 F30 although there’s some N55 parts that have fit in my car like it’s meant to be so does this work for that?

[@protuningfreaks]

Flex fuel kit itself will install but software required on dme isn’t available for the n20 yet so in that respect it won’t be useful

[@Slowww_F30]

@@protuningfreaks when will you guys develop more software for the N26/N20? I’ve been waiting for some time as some of my buddies on things like this as Rolling anti lag and other things on other platforms. Are you guys in the works of that? Or will something like that ever be a thing?

[@blacKdontE2]

Does the kit specifically have to be wired into terminal 15 or will it work with any pin what has power when ignition on?

[@protuningfreaks]

Terminal 15 is a name for the ign on circuit anywhere its found on the car

[@sykhii]

would this work on the 2021 bmw 330e?

[@JohnUnnever]

Just out of curiosity, what is it about the Supra's design that makes the engine bay location the only viable option?

[@tlcnails2007]

I’ve got BM3 kit installed on the Supra last week and I think it is the best kit on the market.

[@protuningfreaks]

Fuel hat is on the bottom of the car, facing down at a 45deg angle towards the driveshaft, and has no lid lol

[@PhilipFairhurst]

on the eu/uk a90 is the wiring install done through the same side,wich would be driverside footwell and not passenger, thanks

[@protuningfreaks]

BDC unit that you connect to is always opposite the steering wheel side

[@PhilipFairhurst]

@protuningfreaks on the UK car it's on the drivers side so basically you can't access the location through the firewall like on the lhd models is there another way too get the sensor side wire through too the main module

[@ryansamlall7134]

Would it be more recommended over the bm3 flex fuel fitted with the lpfp? Thanks

[@protuningfreaks]

Either option accomplishes the same but we recommend the OEM fuel hat location kit for its stealth factor. Once installed, its nowhere to be seen and everything just works :)

[@dakidd4415]

Greetings Is there a video for the X3 F97 installation of this kit? The engine bay looks different from the Supra

[@protuningfreaks]

DIY Instructions are on the bootmod3 wiki website.

[@Fliporflop_Garage]

​@@protuningfreaksI don't see any instructions you guys have look out got us suv guys.. looks Like I will need to do a video

[@Jd-bp1ws]

Will you be making a video for s58/ fuel hat kits?

[@protuningfreaks]

Check our other video, it is done there

[@Mike-jt4tg]

Did you guys make one for an 2016-2019 f33 b48?

[@protuningfreaks]

Same one works as the gen1 b58 but before buying you should email [e-mail] to see if your software is supported for flex fuel

[@BADCoDGAMER]

Does the install for S58 X4M F98 require that last step too?

[@protuningfreaks]

Which last step?

[@erich1308]

G30 B58 Flex Fuel kit ready yet ????

[@redarmy5207]

Yes, same one as this or the oem fuel hat location kit

[@protuningfreaks]

Yep

[@FunkiologyStudios]

After I install on my mkv Supra, do I have to run the ots multimap stage 2 or can I run my current stage 2 91acn? Currently femto unlocked

[@protuningfreaks]

Whichever map you’d like to flash, doesn’t really matter

[@yguncho4371]

I hope i get answers. could gen 2 stock hplp works with this flex fuel kit? Do i run full e85 with these setup or do i need to blend e85 to get e50?

[@protuningfreaks]

Once you have the Multimap OTS or a custom flex fuel tune, you can run any blend from 0-100% e in your car.

[@Cali4nium]

Is this the same install steps for the F97/F98s?

[@protuningfreaks]

Different but very similar. Instructions are on our website.

[@Sumaxc]

How do you view ethanol % on the dash on a car that has customROM?

[@protuningfreaks]

Pull down on cruise button to 1st position and hold. You need the flex bm3 fuel kit hardware on the car for it to work

[@theunkownmr.562]

I'm still new to bummer, so will this work on a 2023 330e?

[@protuningfreaks]

Email [e-mail] to confirm functionality for your vehicle

[@theunkownmr.562]

@@protuningfreaks will do. Thanks!

[@jonathannemchinsky2481]

Will a s55 bm3 flex fuel pump work for a a90 supra?

[@protuningfreaks]

We don’t provide pumps. If you meant the flex fuel kit, no an s55 kit won’t work on an a90 supra.

[@tlcnails2007]

I’ve got BM3 flex fuel kit installed, waiting for the DME come back from Femto to flash with customRom. My question to your is. Can Reflex+ can be use conjunction with BM3 for PI setup ? Or any PI controller your recommended to use for PI. TIA

[@protuningfreaks]

We have our own board coming out this year that will be the best way to integrate PI with bm3 CustomROM.

Yes

[@JordanVentura-z5x]

Im tuned with bm3 on 91 ots map right now. Can I install this on mkv supra and run full e85? Or what else do I need

[@protuningfreaks]

Yes you just need the flex fuel kit and our MultiMap OTS or a custom tune

[@JordanVentura-z5x]

@@protuningfreaks i was told for full e85 you would need port injection and an upgraded fuel system either low pressure fuel pump or high. So are we able to run Full e85 without these?

[@protuningfreaks]

@@JordanVentura-z5x depends on power goals but to run for instance bm3 OTS MultiMaps you don’t need any secondary fueling

[@G80_Cory]

How do you install this on s58 g80 ?

[@protuningfreaks]

Watch the video :)

[@truittkeeler]

​@protuningfreaks we did but since the G8x has dual high pressure pumps and we don't have a fitting the instructions are not the same.

[@noniecaburnay7401]

😊

[@snowman2834]

The s58 is different, it doesn't work like that and it doesn't fit either

[@protuningfreaks]

Only slightly to the point the change is obvious though :) S58 doesn’t use the extra fitting that we use on the B58 that’s all

[@garthbanton4236]

@@protuningfreaks what’s that fitting size

[@350z33hr]

Where do you read the fuel content?

[@protuningfreaks]

Rught in the dashboard on the RPM gauge. Press a button on the steering wheel and see it on RPM, 5000rpm = 50% ethanol for example
