Utilize your Android mobile to adjust your engine
The BMW N54, N55, S55, B58, and N13 engines can now be tuned and monitored via an Android portable software called MHD Flasher. With the N54, N55, S55, B58, and N13 motors, BMW left a huge amount of power on the table while still maintaining the intricacy of the original engine management program, as seen by the MHD Flasher.
N54, N55, S55, B58, and N13 Flash Tunes in the BMW MHD Tuning App
For the turbo BMW N54, N55, S55, B58, and N13 engines, MHD offers flash tunes. Their app is simple to use and simplifies BMW tuning. However, only Android-powered devices can use the software. iOS is out of luck because Apple forbids the use of USB cables from third parties (not completely). Don’t worry; we’ll discuss this in more detail later on. Let’s get started by talking about the capabilities of the MHD tuning app and how to flash tune your turbo BMW.
Put flash maps on your BMW or wirelessly encrypt your vehicle to add secret features.
The MHD UNI WIFI, the newest and best MHD WIFI adapter, is being introduced by MHD Tuning. It’s the best wireless connection setup for using the top mobile apps to tune and code your BMW & Supra MK5!
The only WiFi adapter that supports both the required protocols for contemporary BMWs and Supra MK5s is the MHD UNI WiFi Adapter:
CAN is needed for the E series and for the G-Series/Supra ZF 8HP transmissions’ xHP flashing.
Highest Quality and Flashing Speed: Our MHD UNI WIFI adapter was entirely created in-house by our engineers and was constructed using only the best components and a cutting-edge chipset. It is the fastest adapter currently available on the market, achieving faultless reliability while moving more quickly than earlier generations of adapters (black, orange, blue, pink).
Flash times for ENET cars (F/G Series) and KDCAN cars improved by 5% and 30%, respectively, in comparison to the black MHD WIFI adapter (E-Series). Additionally, the connection stability was increased, which sped up flash times.
App Support: The top BMW apps, including: are compatible with our new MHD UNI WIFI adaptor.
Additionally, the software on this latest generation MHD WIFI adapter is upgradeable, allowing for the future addition of new features, capabilities, and platform support.
This flash adaptor is compatible with the BMW, MINI, and Toyota GR Supra 2020+ mobile apps using the BimmerCode service. With BimmerCode, you may modify, tweak, and access secret functions of your vehicle. For more details and features, see BimmerCode in the mobile app store.
An MHD license is what?
The MHD software can flash your car with the Flasher license unlocked. (No OTS maps are present.) Features: 1. Our MHD WIFI Adapter has the fastest flash times available (5 min initial, 30 sec map switch)
Why would MHD tuning be used?
If you’re familiar with MHD flash tunes for the N54 and only want to know the suggested supporting mods and horsepower, you can skip to the next section. A brief history of MHD’s OTS (off the shelf) flash tunes for the N54 is provided below. When using flash tunes to aim more aggressive boost, the ECU/DME is effectively rewritten. The DME may be flashed to provide the tune complete control over fueling, ignition timing, AFRs, and other factors. Flash tunes, as opposed to piggyback tunes like the JB4, have this as a key advantage.
Advanced boost controllers, such as piggyback tunes, “trickle” the DME. Contrary to flash tunes, they do not have total authority. Piggyback tunes merely operate at a higher boost level than stock, allowing the factory DME tune to make the required modifications. We do not want to criticize piggyback tracks for this fact, which some people will do. It is crucial to highlight that we use JB4 piggyback tunes on our N54s and strongly suggest this configuration to others. Piggyback songs do have limitations, though. The factory tune with a piggyback eventually runs out of gas trying to keep up with things like fuel flow.
Flash songs and MHD’s OTS flash options are now available. For the N54, MHD provides four “stages” along with various maps within each stage based on fuel quality. Their flash tunes have a strong track record and are popular among N54 users.
What are some uses for MHD?
The tuning community first concentrated mostly on piggyback tuning possibilities during the N54 era. There were even fewer ready-made solutions and fewer flash tunes. Arise MHD. Installing and uninstalling the MHD flash tuning maps is simple. You can data-log and make sure your BMW is operating at its best using the MHD app. You can also collaborate with tuners to develop unique flash maps. Additionally, MHD provides the following custom flash options:
- Exhaust noise (we do NOT recommend this)
- reducing cold start noise
- Deactivation of the kick
- Fix for MT shift muck
- Fix for waste-gate rattle
- power per gear cap
These are only a few of the numerous possibilities available when using MHD flash songs. In the instructions for particular engines that are mentioned above, we also discuss these options in more detail. The rest of this article will discuss the steps involved in flashing your BMW ECU and the materials needed.
Is Bootmod3 or MHD superior?
Their maps, in my opinion, make the largest difference. Tuners and programmers are Bootmod3. The same team manufactures everything internally. MHD only consists of programmers; they purchase maps from independent tuners and provide them as their pre-made maps.
Which is preferable, MHD or JB4?
- For larger turbos, it cannot be used as a standalone tune.
- The stock ECU timing table and fuelling are limited
The JB4’s drawbacks might not matter if back-end flash tunes combined with the JB4 resolve these problems. For the JB4, MHD provides certain back-end flash maps that are quite affordable. The timing, VANOS, and fueling are moved to the flash side by the back-end flash, but the JB4 keeps its more precise boost control, in-dash gauges, E85 autotuning, and many safety features.
What more HP does MHD add to N55?
BMW’s switch from PWG to EWG gave the N55 a little more life. Even though it is still not quite as powerful as the older N54 engines, the N55 PWG examples have a little bit more breathing room. Anyone wishing to increase the power of their F chassis N55 has a great choice in MHD flash tunes. MHD provides a number of pre-built tuning choices that are made for various supporting mods, power objectives, and boost targets.
The moderate Stage 1 MHD tracks might not be enough for some people. Stage 2 tunes get a respectable rise in power, around 340–375 whp. For stage 2+ tunes, adding a catless downpipe provides a significant performance gain. On good fueling, power is generated at about 400whp. Finally, E20 maps provide some encouraging data, but there isn’t a significant improvement above 95 octane. However, we strongly advise choosing an E20 map if all you have access to is 91 octane. Naturally, assuming you have access to E85 as well.
How is an MHD logged?
After purchasing the datalogger, I searched the forums but was unable to get any clear instructions on how to log using MHD. Do I only need to draw a few WOTs in third?
There will be a tab that says “start logging” when you click the monitor button. From there, you can select the gauge type and functions you wish to watch.
Once you set up an account, the logs will be saved in the mhd folder on your Android device and you may datazap them from there.
If you’re attempting to determine this.
Other than that, you just mash on it in third. I’ve read posts about various tactics, and since I’m in the country, I can floor it from 1 to 5.
The latest release also includes auto logging.
Visit the MHD post; somewhere in the last 10 pages there is a guide they created, and there is a ton of information throughout the post.
If you have the most recent version of MHD, you may choose autolog, and if the gas pedal exceeds a certain percentage—I’m not sure what the amount is—it will begin logging automatically.
I apologize for taking over your thread, but I did not want to start a new one.
If I convert this to HP, it produces roughly 400 HP, which is obviously too little for a standard car. It provides a 0.55 bar lift (8 PSI).
Which torques are appropriate? What causes MHD to provide such high (incorrect) torques?
At the crank, that only equates to 354 ft/lbs. If it’s even close to accurate, it should translate to about 300 feet per pound at the wheels. Don’t take anything too seriously. You lack both the crank and wheel power of 400 horsepower. If you really want to find out, run it through a dyno.
Purchase a Vbox if you’re serious about tracking the changes in a useful way. More useful, real-world input will be given than MHD ever could.
Does Bimmercode support the MHD adapter?
You may use all MHD capabilities on the go with greater speed and ease thanks to the MHD wireless adaptor. You may rapidly flash, log, read codes, etc. without using a cable by just plugging the adapter into the OBDII port and pairing your mobile device to the Wifi access point formed by the adapter.
Your phone’s LTE/4G data connectivity, bluetooth, and ability to be charged all stay active while using the MHD wireless adapters.
Adapters work with your favorite third-party programs, like xHP, xDelete, Thor, Protools, Bimmercode, and many more, or they soon will.
MHD anti-lag, what is it?
Antilag enables you to accelerate slowly while building a predetermined amount of boost, then take off swiftly once unleashed. Press and hold the cruise control RES button or the DOWN rocker switch on your steering wheel while applying strong throttle to engage antilag.
How many HP is MHD Stage 2 equipped with?
The stage 2 N55 MHD song is starting to get noticeably more harsh. Targets are propelled up to 14–18 psi. However, have you noticed that the top-end PSI still tapers down to a level that is similar to the tunes from stage 1? This is due to the modest stock turbo’s inability to propel enough air upward. The more impressive torque on the low- and mid-end will be produced by the higher boost targets. Additionally, the addition of a N55 catless downpipe will increase that. No matter the track you choose, in our opinion, this is a fantastic mod. Faster turbo spool will win over the butt-dyno. On the dyno, though, the torque gains will also be noticeable.
The N55 MHD stage 2 tune is predicted to produce between 310 and 340 whp. Boost targets are starting to get aggressive enough where ACN91 starts to lag behind regular 91 octane. Boost aims on 93+ octane will probably reach about 16–17 psi with all of the advised auxiliary modifications. Peak torque gains are quite good in comparison to earlier stages given the added boost.
