[MHD Tuning]

After 10 months of development and extensive testing with over 50 B58 test cars all around the world, we are proud to present our newest tuning solution for the BMW B58 engine.

We would like to use this official thread to gather discussions, updates, user logs, dynos and videos. Community feedback has helped us shape the best tools and maps for E-series & F-series, so we're counting on everyone to repeat the same joint effort.

To get things started, here is the product description.

MHD Flasher F+G-Series (N55/S55/B58/N13)

The MHD Flasher F+G-Series is a complete flash tuning app for your BMW. Unlike a piggyback module, it is capable of complete DME remapping while retaining all OEM safety mechanisms. This allows for maximum performance,maximum safety, and unrivaled drivability.
Several thousand customers worldwide have been enjoying the number one flash tuning tool for the E series N54 and N55 platforms (MHD Flasher N54 / N55 E-series) since 2015 and F-Series (N55,S55,N13) since 2018.


Product details:

Full OBD Flashing:
You can install MHD right at home and start tuning immediately! There is no need to remove and send out your DME for a costly “unlock.” Simply download the MHD Flasher F+G-Series app that connects via a K+DCAN cable to your Android device and your vehicle’s OBD-II port, start the app, and within 15-25 minutes the initial installation is complete. Further map changes are much faster - only 1-3 minutes! You can revert your vehicle to the factory OEM flash at any point, and no initial backup is necessary.

FAQ:
Q: Can I test the connection before making a purchase?
A: Yes, simply tap the MHD Store button. The ECU connection is checked before displaying available purchases.

Q: Can I tune different cars with one license?
A:Each vehicle has its own unique license (VIN and google account locked), tuning a different car requires purchasing a new license.

Q: Can I tune multiple cars with one google play account?
A: Yes, you can purchase multiple licenses with one google play account.

Q: Can I transfer my licenses?
A: Licenses are personal and stored by google along the account used at purchase time. The purchases are tied by google to the first account and can’t be transferred to a new google account.

Q: Does my Android device need to be permanently plugged to the OBD port?
A: No. Once a flash is performed you can unplug your device.

Q: Do I need to purchase a new license each time I flash a map?
A: No, you can reflash as many times as needed. MHD maps updates are free.

Q: Is a battery charger required?
A: It is highly recommended for long flashes (install, uninstall). A healthy battery will handle short flashes (map changes) fine but the use of a battery charger remains recommended.

Q: How do I take good data logs?
A: Press the Monitor (auto log) button, stabilize around 2500 rpm / 3rd gear (4th on 8 speed AT) with DSC fully off. Mash the pedal, shift at 6500 and 2-3s after the shift into 4 release the throttle. Slow down, stop the monitor. If you want us to review your log, then upload the log to www.datazap.me and send us the link.

running Stage 2 with the ethanol mix on my b58 and very impressed. Took no time at all to flash and the tune is great - good advance and nice boost. Car is really humming now.

[JD11937]

Car is a completely different animal now, couldn't be happier with product and support from MHD.

[iManu]

Just wow, having being a beta tester, I was amazed how much a tune can do to the B58. We had M240i that ran 11.3 for the 1/4 mile and X3M40i that ran 11.9.
Also just for the burble option it's worth it!

[B58]

Congrats on the official release. My favorite tune to test around was the stage 2 Ethanol.... highly recommend it to those that have a E85 station nearby.

[Ziyadeth]

is the ots stage 2 good for pure turbo stage 2 upgrade? or will there be a different map for that? wanted to make sure before flashing my vehicle with the wrong tune.

m240 ps2 turbo, 6 speed, meth injection, jb4, 4.5 meow pipe, dinan midpipes, bms intake.

thank you!

[E90ROXS]

So you need the K+DCAN cable and the female usb adapter that connects to your phone right?

Are these runs on draggy or track? 93 octane? Fbo?

[iManu]

Draggy and 94 octane gas with catted DP

Terry from BMS is working on JB4 MHD BEF maps, feel free to contact him.

[Solid67]

Sorry if this off topic but what is the benefit of combining MHD or any flash tune with JB4? I thought a flash takes care of everything since you have access to everything in the DME. So why the need of the JB4?

[Brett530]

The combination allows you to be your own tuner and custom adjust anything you want.

To control boost and meth that’s pretty much what the Jb4 is being used for it’s sorta like a custom tuning device if you use map 6 or 7

461/473 with bms intake, MhD BEF + Jb4 and E40 blend.

Meth and down pipe numbers should be interesting...

From the other forum -

Oh nice..you’re on MP right? I thought the poster meant he owns a 240 and x3 M40 that did those times on MHD so I was confused.

Correct, he posted in the G01 X3 side those mods.

[InstigatorX]

@MHD Tuning Can we use xHP today or do we need to wait for optimized OTS?

What exactly is "Sport cooling mode for increased water / air intercooler cooling" and how does this actually work?

Means the watercooling pump turns on at 30° instead of 40
