Bootmod3 MHD Burbles

[rborane]

Debating between getting Bootmod3 or MHD for my first tune on my M4.

Are the burbles on Bootmod3 enabled on each OTS map, or are they a user adjustable setting with the ability to enable or disable? I know MHD is a user defined setting whether they are enabled or not on any map, but have no experience with Bootmod3.

Thanks

From protuningfreaks (bm3) website:
Some of the map features provided:
- Map Customization through Map Editor
- Top speed limiter removal
- Higher rev limiter
- Exhaust burble (GTS, custom, aggressive mode), switchable with the steering wheel controls in efficient vs. sport mode

And many more.

sounds like bm3 is the way to go.

I have both MHD and BM3 licenses... go with BM3 when it comes to customization of these settings.
The current S55 version gives you:

• OEM
• OTS (the basic PTF burble)
• Original (whatever burble was built into your current tune/map)
• Off
• Custom (user control of several variables - see attached screenshot)

Quick questions

1. For BM3 Stage 0 maps (like CS, GTS), will the OTS and Original setting be the same?

2. If I take the CS map, and then edit the burble sound tables and create my own custom tune.
- OTS will mean what was in the original CS (before edits)
- Original will mean new values as per edited tables
Is this correct?

Thanks.

Thanks for this. What is your experience with the MHD tune, and BM3 and which would you recommend?

I'm not entirely sure and could easily be mistaken. But, I believe the OTS setting is the PTF team's "optimized" burble based on their testing, user feedback, and preferences. The "original" is whatever was initially built into the specific map table (may not necessarily be the same as the OTS burble option, even for a PTF-designed OTS map).

Based on my understanding, your situation of flashing a custom table would result in "original" reverting back to the initial table configuration, "OTS" would go to the PTF team optimized sound, and "custom" settings seem to persist with whatever was saved as your last custom configuration.

Meaning - you flash your own redesigned table and "original" burble will be whatever your table dictates. Then, you tweak the "custom" burble sliders in the tune configuration page and flash it.
After a few days, flash back to OTS, OEM, or original. If you then go back to "custom" in the burble configuration, it will have the same slider values as those you last saved when flashing the "custom" configuration setting for the tune.

I've been using bm3 for several months and have driven with a variety of tunes (OTS Stg2 93 and Stg2 E30; custom 93 and Stg2+ E85). The JB4 is still connected, but in Map0.
Ran MHD+JB4 BMS BEF for several months prior to that (helped test and ran several iterations of the RACE BEF map); initially had only the JB4 for almost 2 years before adding MHD.

Each of the configurations has its strong points and letdowns, and it would be difficult to go through all of it. My best analogy is this:

• With the JB4, the car drove as if 2 brains were trying to compete for control and you could feel the back and forth pull of one trying to compensate for the other to meet the target performance.
• Add in MHD and the BEF, and now it seems like the car has 2 minds, but they were at least on the same page and cooperating more smoothly.
• Swap to bm3, and now it is like the car is once again performing one a single brain in control, similar to stock but on serious steroids.

As far as major aspects of each:

• Price point is a win for MHD.
• Frequency of updates - win for bm3.
• Customization - win for bm3 (being said, I haven't used MHD in a while so they could have improved and maybe even caught up).
• Cloud-based system - big win for bm3
• Various platform/device compatibility (Mac vs Win vs Android; laptop vs tablet vs phone) -
• bm3
• Customer service - bm3

A caveat to the customer service aspect - Terry @ BMS is the standard in my opinion. I've (on multiple occasions) emailed him with near-immediate response. This includes close to midnight while on the side of the road with a drivetrain error; response within a few minutes that contained a revised BEF map to upload and try (which worked perfectly)

Mhd is super easy to use with an Android tablet. You don't need WiFi access like you do with Bootmod3. Price is much better and they just had a new update that basically has everything Bootmod3 offers, including the GTS start up roar. I have used it with my previous 335i and my current F80 M3.

Im using BM3 on the shop's M4 and very happy with the results

Is the burble harmful for the engine? What do you think? (not aggressive one) Thanks.

Not engine but long term to turbos and cats

How long for example?
I will use it just on sport plus mode. Not very often.

In theory yes, you need catless downpipes

I am not sure about downpipe.
Beacuse i believe that the stage2 is not very safe for me. High boost power is also problem for s55 engine.

and O2 sensors

[horsepower_and_hounds]

All nonsense....ran JB4 with back end flash on 93 & e85 mix big boost..... 24-25 max psi for a year then BM3 stage 2 tune with over run for same 93 and E85 mix and never a O2 sensor problem. So that is 2.5 years use and on stock engine and 520 rwhp and never a O2 failure or error code.

Or maybe I was a unicorn.....

Which button do you use to switch exhaust burble?

[bobbyh907]

Just a heads up if you use the boost by gear function. My experience is that the MHD boost by gear is less harsh and more refined overall. I had some weird noise and jerks with the bm3 boost by gear but immediately tried mhd after and it was smooth as butter.

The M1 or M2 buttons. Efficient and sport
