Before Dyno Runs: Stock Performance Metrics
Before installing the COBB Accessport, it is essential to establish a baseline performance metric for the BMW 330i. This is typically done using a dynamometer (dyno) to measure horsepower and torque outputs.
Baseline Dyno Results
The stock BMW 330i is equipped with a turbocharged 2.0-liter inline-four engine, producing approximately 255 horsepower and 295 lb-ft of torque. On the dyno, these figures can vary slightly based on environmental conditions and specific vehicle setups.
Installing the COBB Accessport
Installation of the COBB Accessport is a straightforward process. Users can follow these steps to get started:
- Connect the Accessport to the OBD-II port of the vehicle.
- Turn on the ignition without starting the engine.
- Follow the on-screen prompts to upload the desired tuning map.
- Once the installation is complete, disconnect the Accessport.
After Dyno Runs: Performance Improvements
After tuning the BMW 330i with the COBB Accessport, it is crucial to conduct another set of dyno runs to evaluate the performance gains achieved through the modification.
Post-Tuning Dyno Results
With the COBB Accessport installed and tuned, the BMW 330i can achieve notable performance improvements. Typical results show an increase in horsepower to around 300 and torque reaching up to 350 lb-ft. These figures can vary based on the specific map used and any additional modifications made to the vehicle.
