MHD vs BM3

[banana]

Hey guys so I finally got my F82 M4 almost a year ago now and i want to get a little more power out of it. I'm thinking about going with the MHD or the BM3 but i want the safest possible choice to go with. (i had a very bad experience with my 335i and JB4 tune on it)

Can you guys please help me decide, idk which one to go with/which one is safer. Thanks!

or even if you have a better/safer option than the bm3 or mhd

personally i've only used MHD but to me it's amazing. used it on my old 2011 e92 and now currently am running it on my FBO 2016 F80. app is very easy to use, flashing is quick and easy, and the power is incredible. as far as being "safe" goes, i've never had issues with my cars. it's your own risk tuning the car with an OTS tune anyway so it is what it is. but both MHD and BM3 are highly used companies so i think either will be good. just watch some youtube vids and see what others think about them as well.

The safest option is keep engine stock. If you go to tune the engine, you have to accept the fact that there is always risk of engine failure. There just is no safe way to do it.
Best option is to use MHD or BM3 both are great options and they will give you lot of fun.

Just do it bro

Neither is safer than the other. Both are good products that work similar.

I picked BM3 since buying a used license was convenient, and two of my preferred custom tuners (F80Paul and HCP) both use this platform. I've used four of the BM3 "off the shelf" (OTS) tunes, and also have done four custom tunes, across two F8X platforms.

First flash takes a few minutes. No charger is needed. Subsequent flashes take less than a minute. I like to use my phone and a WiFi adapter for flashing and logging too. Very easy to figure out and use.

[Schultz28]

Can't go wrong with either.

I personally prefer BM3 since Jordan Tuned and Bend Calibration both use the platform.

If you were going custom tuning right off the bat, though, I would recommend EcuTek.

Thanks for the responses guys! I'm still stuck between them both...i think i'm gonna need to watch a bunch of youtube videos on them both lol.

Worth noting - if you're in one of the few states that have begun cracking down on CalID/CVN values during emissions inspection, MHD may be the better route. From my understanding, MHD allows you to revert to your actual stock tune, whereas BM3 reverts back to a generic stock tune which can be flagged during inspection.

For what it's worth I flashed my Z4 back using MHD's generic stock tune instead of a backup of my original one and I passed CA smog just fine.

Thank you! this is great to know. I'm leaning more towards MHD right now

For additional info,

I posted this a few times. From what I've seen with latest MHD and BM3 OTS.
MHD stage 2 seems to target approx 22 psi.
BM3 Stage 1 seems to target approx 22 psi.

I have inquired here what BM3 OTS Stage 2 targets, but have not seen response.

First time hearing about this, I'm hoping we won't be affected for a while

To OP, BM3 here

How long ago was the smog test? This sounds promising.

That was less than a year ago; so after CA started checking for that.

This is false and actually opposite. BM3 since day 1 has flashed to actual stock not some generic file. You can’t even activate with BM3 unless you have a stock file match. I remember my buddy on his N55 with MHD had MPPSK (oem power kit upgrade) and after flashing back to stock to switch away from MHD to BM3 he got flashed by MHD to some basic stock tune. As for inspections people have passed even with Stage 1 maps let alone stock.

I tried both, on BM3.

Interesting. These passed inspections on BM3 you reference, were those in a state that is verifying the CalID/CVN (CA/MA) within the last year? I see you've commented similarly on another thread where the OP themselves failed after flashing to stock with BM3, and passed after being re-flashed to actual stock by Kubax - the only thing changing on the car from the failed inspection to passed.

Additionally, in a local Massachusetts BMW group since the changes this year to the inspection process there have been a dozen or so reports of people also failing after returning to stock via BM3, and having to pay the dealer to reflash in order to pass. Not saying you're right or wrong - but as someone running BM3 and affected by a state now checking CalID/CVN's, I have a vested interest in figuring out what's fact to keep from being flagged and having a state inspector find additional things needing "fixed".

I am due for inspection and preemptively had Kubax flash my DME to a known good state. I have captured the current CalID/CVN's in ISTA and following my own inspection, will flash via BM3 and back to stock and report if BM3 returned things back to the way it found them.

I was wondering the same. I’m thinking BM3 now I like you have 4 maps saved and use steering wheel knob to toggle between. I ve seen some vids, anything needed recommend besides cable from laptop to Obd port and laptop? Not looking to tune with phone or anything esp. if 4 tunes loaded in car.

I have noticed one thing in wireless use:
BM3:


and MHD:



I personally like MHD's simple and small obd-wifi adapter. Super easy to instal and remove.

OP,

MHD team are programmers; they only work on the software, not the actual tuning map. They buy their maps from third part tuners.

PTF (the company that makes BM3) are the tuners and programmers of bm3. Everything is made in-house.

This makes me trust their product and support more.

We offer the Kies wireless adapter for $99 for bm3.

Wish there was a good digital gauge setup like JB4 has. Using BM3 and that's really the only thing I wish it had.

You have the app and use a cable or wifi to get the gauges on your phone or tablet

[Smurfkiller]

Side ? I got the BM3 cables to plug into my phone. Can I use bimmercode thru that cable as well. Or will I need to get a Bluetooth dongle?
