Custom Tuners - Map Pack Guide for Custom Code

This guide along with the Map Packs from MG Flasher will help serve as a template for custom tuners who wish to provide their customers with custom tunes that they can flash via the MG Flasher platform. By following the template provided in the Map Packs, tuners can offer MG Flasher unique options such as: Switchable Maps On-The-Fly, Burbles, Max Cooling On-The-Fly and Antilag.

Base map for Custom Code v7.0+

Using the latest MG Flasher app, users can generate and export base maps for a given custom code version. This base map will contain populated switchable map slots and custom code related maps (antilag, burbles, etc.) allowing for a quicker and smoother tuning process. Exporting base maps can be done from the “Custom Flash” page via “Misc.” sub-menu.

We provide GitHub repository GitHub - mgflasher-team/mgflasher-map-packs: WinOLS & TunerPro map packs (A2L & XDF) for creating custom tunes with custom code support! where we share our files.

We strongly recommend to use GitZip for github - Chrome Web Store (google.com) chrome/edge extension. It allows you to download only the specific files placed in repo.

How to install & use GitZip chrome/edge browser extensions

We provide tuners with the following:

WinOLS

X_MultiMap_full_stock_data_Winols_project_CCv6.9_verXX.ols WinOLS projects (contains the below WinOLS files in a package)
X_MultiMap_full.ols_CCv6.9_verXX.kp WinOLS map packs (available separately)
X_original.bin - random, general b58/b48 Gen1 factory file (available separately)
X_original+stock_multimap_data_CC6.9.bin - custom data area applied (available separately)

TunerPro

X_MultiMap_full_CCv6.9_verXX.xdf TunerPro Map Packs in *.xdf file formats (for use with original and stock multimap data)

The X_original.bin is the stock OEM file (random general b58/b48 factory file).
The X_original+stock_multimap_data_CC6.9.bin is the original file, with stock values in the custom area present for each switchable slot.

The project has the custom features organized by having each one in its own section. All of the required maps for each feature are then contained within the feature’s section as a subfolder.

Switchable Maps Structure

One of the custom features within the project is Switchable Maps On-The-Fly. The use of this feature allows for Custom Tuners to provide their customers with multiple calibrations on dedicated map Slots (0,1,2,3,4) that they can choose by using MG Flasher’s cruise control map switching method.

There are multiple ‘Main’ maps (Slot 0) which contain the stock calibration for the given parameter. Under each ‘Main’ section(Slot 0 – original OEM data), there is the corresponding ‘Switchable Maps’ section with dedicated maps for each Slot labeled ‘S1’, ‘S2’, ‘S3’, and ‘S4’. This structure is the same for the remaining switchable maps that we offer in our solution.

In our design, the KF_MDIOP_1_TQE map is not switchable due to the complexity of the overall function. However, due to demand, we have created a solution that allows the tuner to change the values on the X axis only in SLOT 2. This allows for the tuner to take advantage of a different configuration of the KF_MDIOP_1_TQE map X axis to increase load limiter only on SLOT 2 (originally 200 on B58 gen1).

SLOT 1, 3, and 4 use the main area X axis values for the KF_MDIOP_1_TQE map.

Burble, Max Cooling and Antilag

The Data in these sections is always overwritten by the settings specified via sliders and options in the MG Flasher app. There is no adjustment needed to these maps unless you know what adjustment you would like to make manually. You can disable the option to adjust these settings from the app, and enable to code word within the our custom maps provided.
