Description

Maximize the performance of your BMW B58-powered G-Chassis vehicles with Active Autowerke's High Performance Software Tuning. This aftermarket upgrade involves meticulous remapping of the factory DME to enhance ignition timing, fuel delivery, and throttle response, resulting in impressive performance gains. Designed to work seamlessly with gasoline of average octane ratings while maintaining full emissions compliance, this software provides clean combustion with optimal air-fuel ratios.

Note: Please be aware that BMW dealers can flag vehicles as having modified DMEs, which may affect warranty coverage, even if the original tune is restored. By purchasing and using this tune, you accept full responsibility for any potential warranty implications.

Key Features:

  • Up to 80whp horsepower gains throughout the RPM range (compared to stock with AA B58 Catted Downpipe)
  • Up to 100 ft-lbs torque gains
  • Smoother and more responsive part-throttle transitions
  • Enhanced power delivery through recalibrated settings
  • Modified Vanos camshaft remapping for improved efficiency
  • Available "Burble" Maps for a sportier exhaust note
  • Free technical support and assistance

Available Options:

  • Cold start delete for enhanced performance
  • Stage 1 or Stage 2 maps for 91-93 octane fuel
  • Off-road-only downpipe map for racing applications
  • Burble option for a deeper exhaust tone

  • OBD Flashing Option (requires Femto software and cable for DIY flashing)

Performance Specs:

Important Installation Note: If your vehicle's software was updated after November 2019, you cannot use the Femto option and must send the ECU to Active Autowerke for flashing. Always connect a battery charger during the flashing process to ensure stable voltage and disable any laptop sleep options.
