MHD Maps

[mcbutler]

Hi all,

Well i took advantage of the black friday madness to buy MHD maps super pack.

The literature with the maps states that I can return my car to a stock map if needed and my question is this.

My car currently has a stage one map by celtic installed, will MHD save my current map as the stock settings or does the app actually contain the oem stock map?

Thanks all

The stock map is a BMW OE map specific to that version of the DME..ie it’s a fresh (if maybe frozen in time) copy from BMW

You can keep a copy of your Celtic tune by saving it..see section from user manual


Return to Stock
If you click the “Stock” tab, you will see three possible options.
Flash Back to Stock
To flash back to stock, select the tab Stock > Flash back to stock. This option will uninstall MHD and completely revert your DME back to its original factory state. This can be useful if you wish to return your vehicle to stock before selling it, etc. An original backup file is not necessary for this process as MHD can intelligently generate one exactly for you based on unique identifiers in your DME.
ATTENTION: flashing back to stock requires a long write, so a battery charger is highly recommended!
Flash Stage 0 (stock power)
There are two paths to access this function, either through Stock > Flash stage 0, or Tune > Flash an MHD Map > Version (if applicable) > Stage 0. Both paths through the MHD application will do the exact same thing.
With this flash option, the tune and power level will be exactly as it was stock, however MHD will remain installed so you are able to customize flash options if you wish. Additionally, you will be able to data log enhanced parameters specific to MHD. This is useful if you are trying to troubleshoot an issue but still want the enhanced logging abilities.
NOTE: if MHD is already installed and no flash option change triggers a Long Write, this flash should be a short Map Write. As with the above section’s instructions for OTS / Custom map flashes, you should use a battery charger if doing a Long Write or Full Write (first MHD install).
Generate Updated Backup
To generate an updated backup, select the tab Stock > Generate updated backup. This option will create a *.bin file in the MHD root folder which is exactly your OEM software. While this is not necessary for flashing back to stock, it can be useful if you or your tuner needs an original file to start from for your custom tuning.

I emailed MHD at the same time as posting this and they replied almost instantly, reply posted below -

MHD has all OEM maps integrated, it will not save your custom tune and you cant save it.

By custom tune they mean my Celtic map, I explained the situation to them.

I have already flashed to stage 1+ so it looks like I was misinformed and have lost my celtic map.........

Hmmh….

Maybe what they mean is MHD maps that you tweaked with your tuner can be saved..ah well looks like your Celtic tune is now obliterated…

Do you have a dyno chart with your two iterations of the Celtic tune still?

So how does the MHD compare to the Celtic remap?
