BM3 vs MHD - All Aspects

Let us know which one is actually better in the following aspects:

1 - Performance
2 - Reliability
3 - Price
4 - Features
5 - GUI (Graphical User Interface) aka How easy it is to use the app and how well designed it is.

Let me know if I'm missing an aspect. Point here is to decide who is currently the best, and what can the both of them do to improve their service!

Wow... I must be bored... lol...

Both the same basically.... except...

MHD with proper cable 24minutes for first flash
BM3 is a little faster

BM3 is able to re-sell (so you can buy MHD...lol)

MHD has auto-logging.... just set it and when ever you are aggressive on the pedal it will record.... they just updated their maps and are pulling really strong... very happy here...

I also noticed MHD has "Torque Act Clutch Nms" reading (essentially a built in dyno) and BM3 does not... really nice to see what actual difference a tune makes or other changes by just logging watching the Nms.... very very helpful....

Price wise check for yourself...

I find MHD on your phone is extremely easy to comprehend rite off the bat.... logging can be uploaded right from your phone to datazap for the world to review...

Both have continuous updates

Otherwise both are good tunes...

Tunes pretty similar
MHD interface better IMO
BM3 faster flashes
BM3 add support for new ROMs as they are released

I still prefer MHD but I'm looking into alternatives to be able to use latest ROM.

correct... now the relationship to real world torque I'm not sure the conversion.. I don't know if it has been decreased/ altered to not hit the torque limiter... but gives you a nice history of how your car is running....

First one is before the latest update and second of course after the update... you can definitely feel it in the butt-dyno...

Now you can compare to others running the same mods which is what we have been doing and you can see the actual differences between tunes, bolt-ons etc.... pretty cool huh....

That auto-logging feature is pretty nice! These 2 tunes are in such competition with each other, I'd be surprised if BM3 didn't come out with a similar feature in the future. I run a Stage 2 BM3 91 octane with FBO and I love It! I'm sure people running the MHD feel the same way about their tune. I honestly believe these 2 are so competitive, constantly updating increased features and power, that you can't go wrong with either. If you're buying a tune for your car today, for the first time, I would simply not bother with JB4 or Dinan piggybacks. They served a solid purpose when no was was able to crack the DME for a flash tune, but now that you can flash tune, the only reason I can see to buy a piggyback for our cars today is for potential warranty issues. It seems much more difficult to find you've messed with your ECU when running a piggyback. If you take the time to set the piggyback to stock and completely pull it off the car, you have the increased likelihood that the dealership will not find your ECU tampered with. When we run flash tunes, we all run the risk of being flagged (even if we take all the precautionary measures before a dealership visit).

Both pass the "visual" inspection if JB4 is removed. However, both are equally detectable when data is extracted from ECU...

Either way, you run the risk of "voiding" your Factory Warranty...you'll most certainly void your OE/3rd party warranty as outlined within the "Terms and Conditions"...

I have a feeling you can't go wrong with either. Happy BM3 customer here, but I wouldn't be surprised if MHD does a good job as well.

It may also depend a bit on your car. I hear MHD is better with PWG?

That only works with "JB+" due to the fact that the increased boost is still within BMW's parameters variances when left at 3.5lbs.... otherwise anything more powerful will be recorded by other sensors hence transmission etc and that's how they see if it's been modified with a tune... so I've read...

Autologging is real nice... except when your constantly being aggressive on the pedal then you will have like 50 logs to go thru for the day ...lol...

This license transfer I wasn't entirely aware of, would you mind elaborating?

For reference, I have a 340i now but the lease is up in ~10 months or so. I most likely will get a X3 M40i after that. So in theory I could enjoy my 340i with say a STG1 flash and then transfer it to my X3 down the line (assuming B58 support comes soon)?

Nope, I know a long time BMW owner in Germany who went MHD just because PureBoost resided there and he wanted someone who spoke the language to tune the car.
He was told he needed Custom Tune for anything with Upgraded Turbo and he got XDI HPFP pump too.

I had an X4 M40i for 2yrs and 1 of them I had BM3 since Nov 16' when it was Beta it was so good I stood with BMW brand and got an M3 in July. I emailed sales@ptf team that I had flashed my car back to stock and locked dme provided old VIN and new car vin and no extra cost my license was transferred over to new car.
Incase, I didnt want to transfer it I could of sold it for $300-400 (retail $595). Most importantly, I am not stuck to using Android as I can use iPhone, MacOS and Windows laptop too.

Best thing about mhd is that evetything is done through your phone. You dont need anything else other than the cable. Downside to mhd is that its more expensive because u cant transfer license.

More than likely I'll sell the tune with the car... to me the price difference has no bearing on my decision... more about ease... auto-logging on the phone and then loading up to datazap is high up on my list for I use it a lot... the other thing as you mentioned is all on your phone... just way toooooo easy...

Put it this way... just watch a couple of youtube videos... that says it all..

Last but not least, check how there's barely any MHD Results on Dragy ;-) and if there is they're much slower than BM3 OTS

Anyone in Tri-State can msg me if they want to compare with some BM3 cars as there's barely any MHD willing to go to Mexico. All for fun enjoy !

You can't use that one... MHD is still updating OTS's (just updated and pulling strong)... MHD is more for the autobahn crowd reliability wise and they have stated that.... Once they both are custom mapped it really doesn't matter then...

One thing I did notice glancing over at BM3 thread once in a while is that there is always some kind of issue going on.... Just saying....

Bootmod3 is the most advanced flash tune on the market.

1-they offer strong off the shelf maps, but if you are looking for max performance you are going to need a custom map no matter which tune you go with (Active Autowerke offers the most aggressive off the shelf maps BTW).

2-We sold hundreds of BM3 licenses, have not had a single reliability issue.

3- im not allowed to post price on here

4- Bm3 wins this one easily

5- very well designed interface, never got any customer complaint

Very true. But to be fair, VAST majority of issues were/are user related...not platform related.
