Sounds like the best option is to find a reputable tuner who you want to work with, use whatever platform they use, and get a custom tune. That being said bootmode sounds amazing with the cloud functions. The fact it auto uploads your logs is such a cool feature.
Hands down the best tuning platform video ever. I appreciate all the knowledge and I think I’m gonna start with MG and maneuver wherever need be after. Thank you 🙏🏽
i decided to flash with MHD stage 1 and xHp Flash stage 2… it’s my daily driver and i feel like i have another different beast 😁👍🏼 (B58 440i GC with 8speed gearbox) no regrets at all. It’s amazing!
@@liken1288 well, I haven’t tried Stage 3 but i will do it… what I’ve heard is that stage 3 is the most aggressive and focused for track or circuit use… in my case, I’m daily driving my car and stage 2 is enough. But i can tell you xHp is amazing and it worth every penny!!! 😉👌 same with MHD, i have no downpipe because of emissions here in Europe and MHD stage 1 is more than enough. I feel the car like different and way better than stock.
Been doing a lot of research lately I'm getting tired. Thinking of pulling the trigger on the MHD stage1 for my 2019 G30 540i. Hopefully it's the right choice. First time tuning for me.
I have tested BM3 MHD and MG flasher on my RWD 2018 M240i the OTS maps that better suited my car were the ones from MG. I live in a high altitude area(2600m/8500ft above sea level) the 100-200 kmph dragy test using MHD and BM3 stage 2 98ron map didn’t improve the time at all compared to the stock time (12.5s) while using MG flasher stage 2 98 Ron improved it by 2 secs (10.5s). What I could see from the logs is that MHD and BM3 always requested a fixed target boost pressure across all the power curve, which at this altitude exhausted the turbo pretty quick around 3500rpm, while MG flasher has a variable boost pressure target across all the power curve, so it really adapts to the ambient conditions, and varies the target boost psi. At a lower altitude (250m) MG flasher performed really well too, increasing the target boost psi and handling it dynamically across the power curve, resulting in 100-200 8.7s using pump gas. So in a nutshell I really think the OTS maps from MG work better in different ambient pressures. Last but not least, excellent video Kevin, very insightful… you’re really the man when it comes to B58 stuff.
From someone who has a fbo wrx that has secretly been wanting a 335i for years but now wants a 340i because obviously b58, these videos have been great
for me as an 140i driver from Germany your Videos are very helpful, wanted to say thanks, left a thumb and subscribed already! Go on with this great B58 Stuff!
I’ve been on mgflaher for about a year now and love it. I’ve only had one issue with the wireless dongle not connecting to my phone and I emailed mgflasher and they overnighted a new one to me. Otherwise no issues and great performance
I’ve been asking kern for this video for over a year now. Can’t wait to see what he says… thanks kern 👍👍 this was a great video… this will be one of the best performing videos on the channel.
In the market for a 440ix soon, this was very insightful to watch and it cleared some of the additional unanswered stuff I had about the platforms. Thank you, Kern !
Hello mate I must say this is a fantastic video very informative, I have a 420i I was looking to flash bootmod but I don't know will that cause any problem to the engine as I really do not want that lol .
I have MHD on mine. It was flashed by the tuner after he fitted some parts for me. He sent me a screenshot of the code and since then my phone went faulty and I had to reset it and lost that screenshot. I don't have any issues, but if I do what does that mean? Will it need to be flashed again to get a new code?
I have a 2020 m340i rwd which one should I go with? future mods are the usual dp intake charge pipe on 91 gas? My ECU is unlocked. New to the bmw game HELP? LOL
I started with MHD on my 2020 G20 because I was drawn in by MHD+ and the ReFlex support listed on their website. I was pretty bummed when I activated my super license to find out that I only had access to basic flashing features, so I ended up jumping to bm3 not too long after that, but again I was misled by what is advertised, and I guess my software version is too new and CustomROM isn’t supported yet. I felt like my car was much smoother and happier overall on MHD’s Stage 2 E40 tune as compared to bm3’s Stage 2 E30 tune. On bm3, I encounter this weird oscillation when cruising with any burble setting that’s more aggressive than OEM, and for a while I would experience a weird limp mode-esque power cut when cruising in higher gears and I would roll into the throttle to pass someone or when I would shift at high RPMs under WOT. I’ve been working with bm3 support and we’ve gotten the cruising limp taken care of, but I’m starting to lose patience because now they’re just starting to take the “Oh we’ve never seen these issues before” stance when I’m sending logs showing what their tune and software is doing, rather than going in depth and coming up with a fix for the other issues that I’m still facing. I really want to go back to MHD, especially since now I know CustomROM doesn’t work on my car, but I may also end up going to EcuTek just so I can have more than just basic features, namely flex fuel.
So i have a 2019 440i not the m but the basic sport package on it stock i want to mod it i live in cali so 91 gas i the best for my area i herd getting a flash tune , catless down pipe & a high pressure fuel pump is all i need & if i want a cold air intake what do you guys recommend pls help. & should i go with bm3 or ?
One thing i have noticed is in the German cars it seems much nore acceptable to use an OTS tune than domestic and JDM. I remember the on my mustang it was basically a sure thing you'd blow up your engine if you used an ots over an e tune, same with my wrx
yeah they still aren't perfect, but generally they work great. and all the extra sensors that make german cars annoying are actually doing a good job of compensating for various conditions, fuel, etc.
Great video, what tune would be best for x7 m50i to perform like a x5m? Just looking at stage one … and if you have a stock muffler can you adjust the sound and burbles for it ?
In the U.K. MHD didn’t like the fuel and was pulling timing like crazy , mhd said timing correction is fine but was not convinced , have now got custom tune with hardly any corrections at all 💪
I always thought the logger for MHD was very useful to use! Not difficult at all. I guess I would need to use the other apps to see how much easier they are, but I never had the thought that it was difficult on mhd. I would recommend getting it despite the opinion in this video.
It's way more cumbersome than others. The fact that you can only see 6 parameters at a time and always have to scroll up and down sucks. Also the chart doesn't scale based on the parameters.
@@kern417 umm what? Only 6 parameters??maybe I'm missing something, or perhaps you are... But I just pulled up an old log and i have 14 parameters selected that were logged and monitored on a chart all at the same time (AND I can choose whatever parameters out of 80 choices of parameters I want to see upto 14 at a time even after it's been recorded) and from what i recall sclales up/down.. It's also easy to scroll along the WOT time frame smoothly... I can't imagine it would be different than what you see (N54)
@@Spirited_Driver you have to scroll to see all parameters. So if i want to see rail pressure, boost, and lambda, I'm scrolling up and down to see the readings on the bottom half of the screen. Also having rail pressure at almost 3000 ruins the scale for boost and timing that are less than 20. Makes the visuals frustrating.
@@Spirited_Driver when you're trying to see things like if overboost affects rail pressure dips or timing corrections are affected by fuel trims, it's pretty annoying 🙃 that's why i just upload to datazap to get full control
The other day I put my automatic m2 g87 in manual mode without realizing it, I went out accelerating at full speed, thinking that I would change in the red zone but no, I reached the injection cut-off, is the car prepared for that situation?
I have a 23 m240i with a high flow catted dp. I am looking at BM3 OTS for the car after the FEMTO unlock is done. I would be silly if I wasn’t nervous about pulling the trigger. What problems have you come across with BM3 OTS tunes? I don’t plan on using an E mix very often but will always fill with 93 here in Florida.
That’s what I was also thinking. I’d prefer them to be open all the time and if I can make that happen without unplugging or otherwise modding the grille I’ll try it. I just got a letter from BMW issuing an 15-yr extended warranty on the active grille system for possible failure. After watching your comparison video I’m more confident than ever giving one of these tunes a go. Thanks again for all the work and advice you freely give!
Am I able to easily go back to the stock map for the purpose of passing the emissions test with these? Or should I stick to JB4 if I want to be able to do that?
1. Hello man. Thank you very much for your content. Very technically detailed. You are one of the best. 2. For a M240i Xdrive, with catless DP, but with gen1 BMW HPFP (no upgrade), is it safe to fun MHD Stage 2 (not stage 2+) tune? Or do you suggest to stay on Stage 1 MHD? Thank you
@@kern417 oh wow thats def where its at. Does the stock map come with mhd automatically or do you need the pack of maps to get that? Because otherwise I'm almost thinking it would be better to skip all the ots maps and go straight to custom ones. but obviously being in cali I need stock map for SMOG
man i loved this! i’m getting a 240i xdrive soon and this was so helpful. when do I have to worry about internals? i plan on trying to reach 550+whp and ik i’ll need a turbo
To use the gauge dashboard with your phone do you leave your obd adapter on and your phone in airplane or can you just do ad you please with your phone ?
@@kern417 I just wanna use it to see my psi and temps I wouldn’t log any times or anything do you think that it would get messed up for me having those pulled up and do you leave the adapter plugged in?
Well done dude. Thank you. but i would appreciate if you could describe more direct impressions specially between mhd vs mgf. in my opinion, mhd has more low end torque while mg flasher feels smoother... almost like a natural aspirated engine but on top end mg flasher begins to raise. above 220kph mg flasher is pulling like a bull while mhd gets milder and milder. mhd has top much torqe in low end but less top end. opposite with mg flasher.
Fantastic video. I never knew about these tuning platforms until recently. I am contemplating a BM3 for my X3M40i (Gen 2-B58). My goals are really simple. I just need a little extra power and torque and I don't want to move ahead of 91 Octane fuel. Is this a good platform option and what gains can I expect? Also, I don't recall seeing a pricing option for new vs. used for BM3. Thanks again for this great video.
Hi all, I have a 2017 540i, all stock. I would like to gain some horsepower. Nothing crazy, just a few more horses. Any experience with this is greatly appreciated
Do you know if mhd is going to add launch control or no lift shifts for the 6mt gen 1 b58 ? If not what are your thoughts on adding a wot box for those features?
Correct me if I'm wrong, but based on current pricing, MHD seems to be more expensive than the Bootmod3, not less? The base flash license itself is only $422, but that comes with no maps and no logging software. Add $165 for maps, brings it within $10 of Bootmode3. Which is still slightly cheaper, but you also don't get any of the logging capability, which is another $165...which now makes it more than $150 more than Bootmod3? Alternatively, Bootmod3 sells their license, with one map and logging software included for $595. And if you want a plethora of additional licenses, its only an additional $50. That certainly seems like better value for the money for me? And again...keeping in mind, that Bootmod3 has resale value....MHD, does not.
Hey there, Kern. Would you be able to recommend some good settings or some good way to reduce wheel spin in 1st and 2nd gear with MHD? I have an m2 competition and it is already spinning as stock. But I’ve purchased mhd license and didn’t want to tweak too much with it. Planning on running gts map at most.. nothing too fancy
Are there any options where I can make my own tune? I used to have a Subaru and there was open source software I used and flashed my car from my laptop.
I'm looking to get the MHD or BM3 for my 2019 X5 40i G05. I would like to have the map switching feature enabled. Does anyone know if it works on gen 2 B58 now? Not many people tune the X5 so I'm looking for any helpful info with these 2 platforms. Thank you for the help!
I have a 2018 340i xDrive and right now it's on a BM3 Stage 2 91 map, and xHP Stage 3 tune with a catless downpipe. My goal is to hit 600awhp on 91 octane only, with a hybrid turbo. We'll see!

hey man, i know i’m a year late on this video haha, but i was wondering if i can check within the mhd app without purchasing the license to see if my ecu is locked, or if it’s before june 2020 and i’m benchmarked and have to send it in to get it unlocked.
Will bootmod3 come out with full reflex integration? Even if you buy the bm3 flex fuel kit plus the full motiv reflex+ would PI on BM3 still be as safe?
@@kern417 I have a code 21A02D combustion control idle irregular it says you can fix that by updating the software so I updated the software which BMW locked my DMe but now the code is still there and it did not fix the problem have you seen this before I also would have no problem paying you for information knowledge I think you’re smart man be 58 platform and I listen to you over anyone so if you wanna send me a cash app or whatever I would be more than happy to provide payment for knowledge
@@kern417 Yeah when I got a vacuum test done on it or a smoke test done on it BMW dealer said my mass airflow sensor was leaking and my charge pipe rubber coupler band but I have since tightened it and it is a little better I guess I’ll just have to wait till my pcv kit comes hopefully that will do it
Like when I’m at a red light and the light turns green and I hit the gas it takes about a second for the computer to register and by then I’ve hit the gas too much so I end up gunning itl
A question on ethanol free gas which I believe is preferable for many reasons. Have a N55 engine, totally stock, 20K miles. Although with ethanol free the octane level is rated as a few points lower, because it does not have ethanol, that may be erroneous. I am only interested in a stage one tune, and wondering if ethanol free is suitable? Realize its a conundrum... Brilliant vid and very useful!

Does bm3 have different maps you can change on the fly ,1,2,3 through the tack
Can custom tunes be modyfied by the flexfuel sensor? Or is that only for ots pump gas maps (thinking mhd)
You can make custom flex fuel maps yes. That's what I'm doing on my setup
@@kern417 oh wow thats def where its at. Does the stock map come with mhd automatically or do you need the pack of maps to get that? Because otherwise I'm almost thinking it would be better to skip all the ots maps and go straight to custom ones. but obviously being in cali I need stock map for SMOG
The map pack includes all the maps. If you are getting custom tuned then you don't need the map pack
man i loved this! i’m getting a 240i xdrive soon and this was so helpful. when do I have to worry about internals? i plan on trying to reach 550+whp and ik i’ll need a turbo
I just got a 2018 540i xdrive im tuning it this weekend with mhd youll only have to worry at above 800hp range
And all you have to do is change rods and pistons from stock
What about RK-Tunes??
To use the gauge dashboard with your phone do you leave your obd adapter on and your phone in airplane or can you just do ad you please with your phone ?
I don't keep mine in airplane mode but if you get a call or something while logging then it can mess up the data
@@kern417 I just wanna use it to see my psi and temps I wouldn’t log any times or anything do you think that it would get messed up for me having those pulled up and do you leave the adapter plugged in?
Nope it should be fine
Well done dude. Thank you. but i would appreciate if you could describe more direct impressions specially between mhd vs mgf. in my opinion, mhd has more low end torque while mg flasher feels smoother... almost like a natural aspirated engine but on top end mg flasher begins to raise. above 220kph mg flasher is pulling like a bull while mhd gets milder and milder. mhd has top much torqe in low end but less top end. opposite with mg flasher.
What do you think is the best for a stage 1 tune on 91 octane gas in cali that will give me max add hp and torque?
Fantastic video. I never knew about these tuning platforms until recently. I am contemplating a BM3 for my X3M40i (Gen 2-B58). My goals are really simple. I just need a little extra power and torque and I don't want to move ahead of 91 Octane fuel. Is this a good platform option and what gains can I expect? Also, I don't recall seeing a pricing option for new vs. used for BM3. Thanks again for this great video.
yes they all work pretty much the same for 91oct tunes. used prices vary but usually it's around 50-60% of the new price.
@@kern417 Thanks. I am assuming since this is just a software app/maps, there is no difference between used vs. new? Correct?
correct
Hi all, I have a 2017 540i, all stock. I would like to gain some horsepower. Nothing crazy, just a few more horses. Any experience with this is greatly appreciated
Do you know if mhd is going to add launch control or no lift shifts for the 6mt gen 1 b58 ? If not what are your thoughts on adding a wot box for those features?
I do believe they will eventually. They released it for other platforms already.
@@kern417 They actually added nolift shift for 6mt couple days ago and 2step for the 6mt aswell
I posted a video on it last week.
@FlexinJump yeah the NLS is awesome but gen 1 b58 still doesn't have launch control.
Correct me if I'm wrong, but based on current pricing, MHD seems to be more expensive than the Bootmod3, not less? The base flash license itself is only $422, but that comes with no maps and no logging software. Add $165 for maps, brings it within $10 of Bootmode3. Which is still slightly cheaper, but you also don't get any of the logging capability, which is another $165...which now makes it more than $150 more than Bootmod3? Alternatively, Bootmod3 sells their license, with one map and logging software included for $595. And if you want a plethora of additional licenses, its only an additional $50. That certainly seems like better value for the money for me? And again...keeping in mind, that Bootmod3 has resale value....MHD, does not.
The super license is $550 and comes with everything
@@kern417 My mistake....I had the currency on MHD's site to CAD and not USD. Now the price points make more sense lol
@@alfrede.neuman8611 no worries. I still do think they raised the prices at some point
Hey there, Kern. Would you be able to recommend some good settings or some good way to reduce wheel spin in 1st and 2nd gear with MHD? I have an m2 competition and it is already spinning as stock. But I’ve purchased mhd license and didn’t want to tweak too much with it. Planning on running gts map at most.. nothing too fancy
You'll have to play with the boost by gear settings. A better option is to upgrade your tires for more grip.
Are there any options where I can make my own tune? I used to have a Subaru and there was open source software I used and flashed my car from my laptop.
They all support flashing custom tunes
Do both mhd and bm3 work with xhp? I thought i heard mhd works better with xhp
Transmission tunes are completely separate from engine tunes. You can even flash xhp on a completely stock car.
On MHD there's a tick box if you have xHP installed.
@@ScottPC all it does is disable torque intervention. Same on bm3
Does any of these support diesel? I have a 2010 E90 335D
Do they have any maps for 92? My closest couple gas stations have 92 for premium
no, just 91 and 93. you can run 92 octane fuel on a 91 octane tune
I'm looking to get the MHD or BM3 for my 2019 X5 40i G05. I would like to have the map switching feature enabled. Does anyone know if it works on gen 2 B58 now? Not many people tune the X5 so I'm looking for any helpful info with these 2 platforms. Thank you for the help!
Are any of them particularly better when paired with xHP relative to the other company?
nope, completely separate products.
MG Flasher. FlexFuel. Let's gooooooooo....
I have a 2018 340i xDrive and right now it's on a BM3 Stage 2 91 map, and xHP Stage 3 tune with a catless downpipe. My goal is to hit 600awhp on 91 octane only, with a hybrid turbo. We'll see!
My goal is the same! Did you find out which hybrid turbo you’re going to go with?
@@sari.1168 Still not sure yet as it seems like there have been some recent developments by multiple different brands. Kratos, Pure, and Dynamic Autowerx specifically.

@@hassantalib3426 bro stop yelling, this is a B58 thread. ima get a bigger turbo its ok i promise you
😂
hey man, i know i’m a year late on this video haha, but i was wondering if i can check within the mhd app without purchasing the license to see if my ecu is locked, or if it’s before june 2020 and i’m benchmarked and have to send it in to get it unlocked.
Yes you can. Just need an obd adapter to connect to the car
@@kern417 Is it any WIFI OBD adapter that works?
@@Verellic The Kies Wifi ENET Adapter works with it. I used mine to check if my ECU was unlocked 👌🏼
Going MHD in 2 stage 2 weeks 2020 M340i
Will bootmod3 come out with full reflex integration? Even if you buy the bm3 flex fuel kit plus the full motiv reflex+ would PI on BM3 still be as safe?
I would be shocked
I believe they are working on it but I don't know when it would actually happen
Does anyone know which platform has the most aggressive crackles and pops?
Thoughts on DINAN + PERFORMANCE ENGINE SOFTWARE - BMW B58 (M0) ENGINE, im confused if this is applicable to the b58m30a engine bc of the (M0)
More expensive with less gains/options than the other tunes
Would the MHD work for my 330e?
ecutek?
I need guidance, cant make my mind up between the 3 for my G31 540i 😫 initially going stage 1, but aiming to go stage 2+ progressively 🤔
MHD or BM3. not MG
@itily yeah after some reading it seems like MG is playing with timing and iat with their tunes. So leaning towards mhd superlicense.
@@ooopppiiiuuummmwhat is wrong with Mg im on Mg ??
@@bmwsincekid while MG is a pioneer tuning platform for the b58, it’s been outshined by MHD and BM3. the other two platforms are better for tuning
@@ooopppiiiuuummm Okay But whats wrong with MG ? I have no isses with it…
Hey kern If I was to do a quick OTS map from MHD do I need to gap up my spark plugs
No
@@kern417 I have a code 21A02D combustion control idle irregular it says you can fix that by updating the software so I updated the software which BMW locked my DMe but now the code is still there and it did not fix the problem have you seen this before I also would have no problem paying you for information knowledge I think you’re smart man be 58 platform and I listen to you over anyone so if you wanna send me a cash app or whatever I would be more than happy to provide payment for knowledge
My understanding is updating the software usually fixes it. Are you sure you don't have any air leaks or anything? Check your pcv?
@@kern417 Yeah when I got a vacuum test done on it or a smoke test done on it BMW dealer said my mass airflow sensor was leaking and my charge pipe rubber coupler band but I have since tightened it and it is a little better I guess I’ll just have to wait till my pcv kit comes hopefully that will do it
Like when I’m at a red light and the light turns green and I hit the gas it takes about a second for the computer to register and by then I’ve hit the gas too much so I end up gunning itl
I have a 2023 M340i. Wondering your thoughts on JB4 while waiting for a flash tune unlock to become a available.
It works but I'm not a fan of piggybacks
what’s the site to upload codes from mhd flasher to easier read diagnostics
bmwfault.codes
That is one big ass turbo, sir.
why thank you
@kern417 Basically you prefer the MHD 😅
I'm leaning towards MHD, people say bm3 is a bit more aggressive though 🤔
At the end it just depends on the driver, mhd ots got me 60-130 of 8.2
Nah jts the otherwise around. Mhd is more aggressive
I was thinking about Eurocharged do you know anything about them?
Yeah they do custom tunes
A question on ethanol free gas which I believe is preferable for many reasons. Have a N55 engine, totally stock, 20K miles. Although with ethanol free the octane level is rated as a few points lower, because it does not have ethanol, that may be erroneous. I am only interested in a stage one tune, and wondering if ethanol free is suitable? Realize its a conundrum... Brilliant vid and very useful!
Run whatever the tune is designed for.
