Two BMW base maps are now available directly through the Base Map Loader – no manual download needed.
NEW: BMW B48B20A Gen 1 (v1.0)
The map controls:
- GDI injectors and high-pressure fuel pump
- Electronic wastegate and throttle
- VVT solenoids
- Knock control
- Closed-loop oil pressure control
- Alternator control via LIN
- Electronic thermostat with closed-loop temperature target
UPDATED: BMW B58TU Gen 2 (v2.0)
What’s new:
- Full thermostat control
- Improved high-pressure fuel pump control
- Improved EWG and VVT control
- Improved knock detection
The B58TU pinout has changed in v2.0. If your car is wired for an earlier version, check the new Inputs and Outputs assignment before loading.
Good to know:
- Both are engine-only maps – vehicle components (low-pressure fuel pump, fans, starter, etc.) must be configured separately.
- Valvetronic is not supported – intake valve lift must be locked at maximum opening.
How to use it:
Download New EMU PRO software version 261.2.2.
Open File / Load Base Map… and select the B48B20A Gen 1 or B58TU Gen 2 base map. For step-by-step instructions, see How-to Load Base Maps in EMU PRO
As always, base maps are a starting point – careful tuning is still required, and all assigned inputs/outputs must match your wiring before loading the map to your ECU.
