Pleased to announce we've partnered up with MHD to utilize their flashing platform for JB4 B58 customers to load up back end flash maps!

The B58 flash maps allow us to control aspects of the tuning previously not possible using JB4 alone including changes to the factory fuel caps, torque limiters, throttle behavior, speed limiter, fueling algorithms, and much more. When the JB4 alone isn't enough this is going to be the next step to take your cars performance to the next level. It's especially beneficial for those who want to run E85 mixtures and larger turbos.

Click here to download the latest back end flash maps. Note they are subject to change and when we make revisions we increment the number on each one to keep track of the changes.

How to load:

1. Download the MHD F chassis flashing app from the android store
2. Using "stock maps" operation load Stage0, this requires purchasing the MHD flashing license for $249. Do not purchase any MHD maps or the logging module as we already provide those for you free of charge.
3. We expect a lot of mapping changes so email us for the proper starter map for your situation, terry@burgertuning.com, you'll email back logs, and we'll go from there. Once all maps are stable we'll add them to this thread.
4. When loading flash maps use the "flash a back end" option. There are some MHD flash time options you can select as desired.
5. For flashing support, either email mhd.tuning@gmail.com or the MHD B58 what's app group : WhatsApp Group Invite
6. Update your JB4 firmware to v12+ and set options (future use d) bit 6 on so the JB4 knows you have a flash map loaded.

JB4 B58 map guide as of v13 firmware:

Note FutureUseD bit6 must be enabled for correct mapping when flashed

Map0: Stock tuning, fully disable JB4
Map1: Flash mapping with JB4 active for in dash gauges, boost by gear, CAN flap, etc
Map2: Absolute target map peak boost of 16psi
Map3: Absolute target map peak boost of 18psi
Map4: Absolute target map peak boost of 20psi
Map5: Absolute target map peak boost of 22psi
Map6: Custom tuning map allowing both additive (below 10psi) and absolute (above 10psi) targeting
Map7: WMI map (boost varies based on WMI additive and map settings)
Map8: VALET/Low boost safety map

JB4 v13_1 firmware:

1) Made fuel pressure safety more sensitive

JB4 v13 firmware:

1) Added active safety system for high fuel pressure. JB4 will revert to safety is fuel pressure drops below 7 (1000psi) during full throttle.
2) Moved safety/VALET map to map8
3) Adjusted map4 to be a performance map between map3 and map5. With the BEF map4 targets around 20psi
4) Adjusted FF learning to be slightly more aggressive.

I'll start a FAQ as well and update it as we go.

How much is the MHD B58 flashing license?

The flashing license if $249, and we will be providing the map templates free of charge, so you don't need to purchase any maps. Additionally you'll be using the JB4 for all data logging so do not need to purchase the extra logging module.

Is any special hardware required?

MHD requires an Android device. If you don't have one any generic $50 tablet or phone will do. In addition you'll need an MHD compatible flash cable. We suggest the BMS cable for $29.

Once I flash the DME can the dealership tell? What if I flash it back to stock?

Modifying your vehicle is not without risks and we believe flashing the DME is traceable even if flashed to stock. If you are really concerned about your warranty, it's best not to flash your vehicle. That said when used in conjunction with the JB4's expanded safety systems and mapping use/guidelines, expect a relatively high level of reliability at the elevated power levels.

What flash time options are available?

Certain settings can be toggled on/off or adjusted during the flashing process itself. Including the user adjustable exhaust burble settings, speed limiter delete, cold start delete, CEL delete, etc. MHD will be adding these as their development progresses.
