Just picked up my 340 today! These videos and your knowledge 100% convinced me to make the move. Thanks! All this info is incredibly helpful
This is the best channel on B58 tuning ever. I learn so much from every video. Thanks for putting these out there.
Appreciate the support. More coming soon
I too sip my coolant from a straw
Another banger 🙌🤙 “Kevin’s coolant” LOLL
Hey sir great video and channel! Just one question I hope you could answer for me. Could I run a E50 tune and use pump E85? Would there be little to none hp difference? Basically, all the pumps say minimum e51 so I'm trying to avoid running lean/knock, and not installing an ethanol sensor.
I have a video on how to calculate an ethanol mix. Watch that video
Can you run a mixture of 91 & E85 on a M340i 2021 with the jb4 tune ?
Yes jb4 e30 I believe
So how do I go flex fuel for a manual gen1? Is motiv reflex the only option? My car is currently stage 2 91 DP intake, eventually I want stage 2+ 91 later or stage 2+ e30 but I need to do my clutch for that thanks 🙏🏽
So you don't need injectors to run 85?
I watched the algorithm content to! You carry on your great content pal 👍
At this time port injection is a waste of money and time and absolutely unnecessary
Thank you for the video ! I got a custom tune to go full E85 yesterday. Do you think I should replace the fuel filter (including pump) in the tank ? My car is 80.000miles old
Should be fine
Is it fine to run full e85 with dorch stage 2 on stock turbo? What would be the approximate power I would be looking at with a custom tune.
You can with a custom tune and it will get you around 480 -500
Just discovered your videos, and it's very instructive and well summed up!
Considering to put my 440i under full E85, I'm eyeing Dorch stage 1 HPFP ^^
Custom tune for you is mandatory if I install Dorch stage 1? I guess for optimal result of course.
Do you know the E85 consumption with a stage 1 HPFP for let's say daily usage?
Any issues if can't find a petrol station with E85 if I put Ron 91-93 ? (E85 is not so common in Europe, but a lot cheaper)
Thanks ;)
You'll need a custom tune for full E85
You can run the pump without a custom tune but you do need custom settings in whatever tune you run
If you want to switch fuels then you need to switch maps for the appropriate fuel you're putting in the car
@@kern417 crystal clear 👌
Forgot to mention that my B58 is stock.
So installing an E85 sensor would be in that case very useful, to switch to proper map.
Thanks a lot 🙏
Any digit on the consumption?
@@ocengoceng2959 it depends on your tune and driving style. E85 used ~30% more fuel than pump gas.
If you dont have a turbo upgrade, your turbo cant even max out the TU pump, let alone the dorch. If you go dorch, go right to the stage 2 its not a big $ difference
Where can I find a port injection kit for full e85?
EOS or Precision Raceworks
@kern417 stage 2 tune an down pipe can run e30-50 w out any other upgrades ?
I’m getting a Dorch Stage 2 Pump for full E85. I believe the results are less going full E85 but I don’t wanna have to mess with mixes. I have already have a catless Downpipe. Anything other than the tune I’m missing?
Nope
What about injectors thought wouldn’t you need that upgraded for that and fuel lines maybe ?
Nope
Awesome, thanks for posting 👍
How quickly does E85 go "bad"? Is it okay if my E50 340i sits in the garage for two weeks or is that going to cause problems?
Yes it's ok. I've had it sit a few months
How often should I do oil changes my last one was at 69k without e85 an now I’m up to 74k touching 75 running full e85
Just depends. Get an oil analysis
Always Killing it 💪
So what’s better e85 or e30-e50
Better for what
Is there a flex fuel option for the b58 platform? Or at least in development?
It's in development. It has come out for S55 and N55 cars, so we're just waiting for it to be released on the B58.
@@kern417 Yup cant wait!
What are your thought on running an E30 mix on the stock, non TU pump?
It's the best
@@kern417 no issues handling the colder burn. Do I need step colder spark plugs to go w it. Just making sure I’m not convoluting all the information out there.
Nope. I ran stage 1 E30 on a completely stock car for about 6 months before getting a custom tune. It's really as simple as flash, fill up, and go. Just make sure you get the mix right.
@@kern417 how does the mix work? Can I just put 2 gallons of E85 in an empty tank and top it off with 93 octane?
I have intake, downpipe, mhd ots 93 (stage 2 hpfp) upgraded to tu pump (i also have the E blend maps from MHD. What else do I meed to safely run e40 without knock timing issues etc
Car is 2019 540xi (g30)
you don't need anything else. a flex fuel kit will make it even safer
King speaks again
can you elaborate more on timing? I have a 2021 BMW X6 xdrive40i and theres no custom tunes on the market for me yet as tuners havent figured out how to unlock the ECU. (DME). I have a racechip GTS but am switching to a JB4 soon. Im getting a catless downpipe and high pressure fuel pump upgrade soon, should I run like E60?
run whatever the tuner is designed for
How come dorch says stage1 hpfp can run full e85 depending on tuner? Is it bad to run full e85 on it
No it can run it fine
Do I have to change my fuel lines to run any kind of mix or full e85 on my 340
no
B58 L engine
Currently catless stage 2 ots with mhd on 340i, mhd offers ots e85 map. Can I go with it with no problems?
Yes
@@kern417it gives me a full e85 option too but I have a stock fuel pump but am I still able to go with the stage 2 full e85 tune? Mhd ots
@@asg9686 stage 2 is designed for stock fuel pump.
did you run into any issues running full e85 on the di only system? i ended up killing injectors within 2k miles of full e85
Nope. I ran it all last year. I switched to E30 once to flush out the system.
Do you need to upgrade any hardware to run an e50 mix?
No
so you're saying all I need is a hpfp and a tune to run full e85?

Hello ! Running on full e85 with a catless downpipe can can make the car undercover for CO emissions controls ? (In France we have every 2 years a technical control of the car and they test CO concentration in exhaust gaz). Thank you
I don't have any personal experience with it but I have heard that it can help to pass emissions. I'm not 100% sure
@@kern417 thank you
May I ask if it's ok to pump full e85 without tune in b58? Not looking for gains just want to put fuel in my tank. It's almost 7 dollars a gallon here.
No
@@kern417 copy, thanks bosh
@@kern417 I'm running 50/50 mix e85/87octane to save money on gas. Runs smoothly with alot more low end torque on stock tune.
@@ralph1rodriguez can I put 2 gallons of e85 on an empty tank and then top it off with 93 pump? What E content will that give me?
@@iJustB58 2 gallons is fine but you'll use up gas alot faster. That's the reason I mix 87 and e85, to land closer to 91 octane so that it has similar energy per volume of. gas.
I wish there was videos on how to go e85 on b48
Everything is pretty much the same
@@kern417 oh really?! Shesh thanks man
hey i was wondering if you can add some e85 in the tank of a bone stock 340i? would it do any harm to the car or would a couple gallons mixed in be fine?
1-2 gallons shouldn't be a problem
@@kern417 will it make a difference in power?
@@saonwheels8613 no
@@kern417 so there is no advantage to filling some up if im stock?
You still running the 550i clutch? Do u recommend it ?
Yes and yes x2
@@kern417 did you do the clutch delay valve removal on that?
@@KSIxKRYPTED yes. The DIY is on my channel.
Hey did you see a noticeable gain from E30 to E50?
Less torque more top end
@@kern417 so slower 0-60 than e30?
@@shelbyhaiketic4212 shouldn't be
@@kern417 what would be the average mpg u think on e50 for the m340i xdrive ??
@@shelbyhaiketic4212 same stock when cruising. Maybe 10% more when flooring it.
Could you go for a water meth kit rather than port injection?
They are 2 different things. Water meth is what you're spraying, and port injection is where you're spraying. So if you're considering meth, your best bet is to run port-meth Injection.
@@kern417 thank you, that makes a lot of sense I’m new to the car scene and your videos are amazing! Keep up the good work.
@@kern417 As far as I can tell you can’t run both via port so if you are running fuel port injection then chargepipe spraying meth is the only option.
He asked either or.
@@kern417 I know, I was replying to you. Since it was an e85 video some people will want to do both. Just adding flavour.
Shit right now i just want to run full e85 cuz its way cheaper than 93 gas😂 but i wonder if the gas mileage will go down up or stay the same
Lower on e85 for sure
Im currently on bm3 stage 2+ 93 gas. Do you know if i would gain or lose or stay the same power if i switch to full e85 with just a tune only . Thanks in advance for replying definitely subbing to your channel
It depends on the tune. With everything equal not much. A mix will make the most power
