BM3 or MHD

I've read all the BM3 and MHD threads and even the vs one but am still inconclusive as to what to get. I'm hoping someone can convince me as I think the flash tunes are a better choice than the JB4 that I have used for a couple years on my F30 and before on my e90. I have no problems with the JB4, but feel as if the flashes will give a different feel to the car and maybe more power.

Guess, it's the feel like modding and want to move into what is in now.

I have spent hours reading these threads and after reading about MHD I want to get that and then after reading BM3 I feel like that is better. I've seen guys posting 0-60 times pretty close but cannot determine if one is faster. Not concerned about price as MHD seems to be a little less--if BM3 is better paying a little more is no problem.

Or maybe they really are the same.

I have a 2013 PWG 335, catless, CP. I do tend to use e85. I have an ENet cable and use android. I do not have the Dkan cable...just a few bits of where I stand and hoping somebody can push me over the edge.

If you are not planning on a custom tune then I would go for BM3 their OTS maps are nicer imo

Can't go wrong with bm3. OTS maps are solid and you can find tuners for custom tune if you want.

You can do a custom tune with both MHD and BM3. They each have separate tuners that can make custom tunes. Honestly, both will give you great power increase and smooth power band. From what i've read BM3 does squeeze out more power than MHD but not sure if thats really a good thing to max out the turbo in terms of reliability. But to each their own, good luck in the future and let us know what you decide to get

BM3 is the more mature platform currently, and has more features.

What features does BM3 have that MHD does not? They both have burbles, e85 maps and CEL clear.

I read that BM3 is smoother and puts out more power than MHD's offering. I'd be interested to hear the key differences as well as I'm about to pull the trigger tonight on a tune.

BM3 has been out since end of 2016 so they have a jump start but give it some time and MHD will offer the same if not more overall

Yeah, I'm hoping somebody helps me decide as I am ready...not in a rush but can't make a decision. So, are you going with BM3?

At the moment yes, I've decided on BM3... Running a AA FMIC and VRSF CP as well as MPPK and MPE. No downpipe yet, still trying to figure out which one I should go for. Leaning towards VRSF at the moment.

This should get me to BM3 stage 1, then I'll go stage 2 once DP is installed. I also have a Dinan Sport piggy, but not sure how it would work into the current setup. Can I have the tune stacked on top of BM3? Anyone know?

Once you flash any tune, you will lose the MPPK tune and no you cant stack to my knowledge.

From what I'm told MPPK will be saved as my stock tune and I can revert back whenever I wanted to.

I have a VRSF DP--it fits and works great. As far as the piggys go--they don't really stack as all the piggy does is control boost, but we would let the flash do that. When I go flash I will remove my JB4.

If you were to keep the Dinan as your boost controller you basically are using the flash as a back-end..but that basically defeats the purpose of why we are going for a flash--to have one device controlling everything in the best way.

FWIW you can resell the bm3 license if you decide to sell the car. Can't do that with MHD AFAIK.

There are just more customizable options like burble sliders (duration, aggression, rpm, etc), cold start idle RPM, N20 TMAP sensor switch, exhaust flap, etc.
Also, E30 and Race gas maps, as well as more options for custom tuners.

Admittedly, I have not really been keeping up with all the MHD development in 2018, but that's also because their online presence is not as robust as BM3.

Key word in my initial post is currently. Obviously, BM3 has been around a couple years longer than MHD (for N55), so they've had a head start on time and user base to develop and tweak. Not saying MHD will not eventually catch up or even exceed what BM3 has accomplished.

Just my 2 cents.

Well MHD has all of those things as well. Plus you can remove top speed limiter, reset all adaptations and not to mention the data logging capabilities.

I'am currently running a 95 octane tune running full 100 octane racing gas on my daily driven 435i Xdrive I'm FBO Stage 2+ and it sure is fun spinning the rear wheels on Xdrive before the fronts kick in.

Also MHD just started a Facebook group page. In addition to their WhatsApp group chat which is great. Plus honestly just had some inquiry's and heard back from them via email and Facebook within 1-2 days.

Either way BM3 or MHD you probably won't be disappointed. The N55 engine is great when tuned.
