The debate between BM3 or MHD has been running for the longest time now and we often find consumers confused when it comes to tuning.
BM3 and MHD are two different technologies used in the automotive industry, so it's essential to understand the specific applications in order to determine which one is better.
Both BM3 and MHD are actually popular tuning solutions for BMW cars and they have outstanding driveability because they are an ECU flash.
BOOTMOD3
BM3 is a flash tuning platform produced by Protuning Freaks. It allows users to alter and optimize the engine performance by reprogramming the ECU (Engine Control Unit) through the OBD-II port.
Features
- Slightly more expensive, but for that price you get access to all maps, logging, full editing, one time license transfer to a different VIN, cloud storage for maps and logs, and stock ECU backup.
Also, BM3 is often favored by car enthusiasts who are looking to level up the performance of their BMWs by maximizing power output and enhancing overall driving experience. However, it's worth noting that ECU modification can void a car’s warranty and could potentially cause reliability or drivability problems if not done properly.
It provides capabilities comparable to BM3, enabling users to alter ECU parameters and enhance engine performance. Similar features like real-time data logging and editable maps are available.
We offer a number of BM3 tunes for your car. For example, F87/F82 cars with S55 engine may opt for the BOOTMOD3 BMW S55 F80 F82 F87 BM3 Remap/Tune License which also comes with a free ENET Cable. This tune comes with only one map of your choice.
You will also need the BMW Wireless OBDII Wifi Enet CANbus Flash Adapter which is an all-in-one device not only for BM3 tune, but it is also compatible with other 3rd party apps like xHP, Bimmercode and Bimmerlink.
If you wish to unlock additional maps, we recommend the Bootmod3 BMW S55 F80 F82 F87 OTS Maps Bundle. Feel free to reach out to us with the details of your car and we can advise the right tune for your car!
MHD Flasher
MHD is another well-known tuning solution specifically designed for N54 and N55 engines. Users can also reflash the ECU using the OBD-II connector, similar to BM3.
It provides similar functionality to BM3, allowing users to enhance engine performance and modifying as well as customisation of maps.
Features
- MHD is a mobile application with a simple user interface. Without heavily relying on the cloud, it’s easier to whip out on the go and correct or modify something. On the contrary, BM3 depends heavily on the cloud.
- Supports a broad range of BMW models and offers several performance stages to accommodate various levels of modification.
- MHD has gained popularity due to its affordability and ease of use.
The MHD Universal WiFi OBDII Flash Adapter has the most seamless wireless support and it is compatible with all vehicles. Just like the BM3, it also supports xHP, Bimmercode and Bimmergeeks Protool.
In terms of which one is better, although it primarily relies on personal preferences, we slightly favour going for the BM3. BM3 is slightly more expensive, but for that price, you get additional features like anti-lag, flex fuel and map switching on the fly which MHD does not offer for certain engines including Gen 1 B58 as of today.
However, if budget is something you’re concerned about, then you can opt for the MHD which offers decent performance as well.
