Selecting maps

A map can be selected by using the steering wheel controls or with the JB4 interface software. Which map you should run depends on your level of modifications and available fuel.

Map Descriptions

Map 0

Stock bypass. This map will run the boost level that the ECU dictates when setting 4/3 is selected, or will target 8psi when setting 4/2 is selected.

Map 1

Suggested for most racing applications. Will target 13psi with setting 4/3 selected, or will target 15psi when setting 4/2 is selected.

Map 2

Suggested for cars with exhaust and 93 RM2 or higher octane. This map will target 14.5psi with setting 4/3 selected, or will target 17psi when setting 4/2 is selected.

Map 3

Progressive methanol mapping with a flow sensor fail-safe. See guide to enable. Meth use isn't supported/suggested without a flow sensor and map 3.

Map 4

Stock map with CAN active. Allows full datalogging and use of JB4's in-dash gauges on the stock mapping. This map will run the boost level that the ECU dictates when setting 4/3 is selected, or will target 8psi when setting 4/2 is selected.

Map 5

Auto-tuning map. Boost ranges between 12-17psi based on your cars octane, conditions, and modifications. This map is fully E85 compatible. If using E85, Burger suggests using around 30% to start. Refer to the E85 FAQ for additional information. This map resets to 93 octane level adaptions when selected and adjusts itself up or down from there.

Map 6

User-defined boost level map. Can be used for custom boost levels, diagnostics, or troubleshooting.

Map 7

Race gas map. 18.5psi peak boost on the G5 ISO. Requires straight 100-104+ RM2 octane unleaded racing fuel (the expensive stuff). Burger does not suggest using leaded racing fuel. To use this map with E85 requires the BMS E85 back-end flash, inline booster fuel pump, and a 60% E85 mix, per the E85 FAQ.
