CarBahn Performance BMW M235i/X2M35i 313 HP Stage 1 Performance Controller - CBPRC-0065

The CarBahn Performance 313 HP Stage 1 Performance Controller is a plug-and-play ECU tuning solution designed for the BMW M235i and BMW X2 M35i equipped with the B48E engine. The CarBahn Performance Controller (CPC) increases turbocharger boost pressure to deliver additional horsepower and torque while allowing the driver to select different performance maps based on fuel octane.

The controller supports selectable 91, 93, and 100 octane maps through a Bluetooth-enabled smartphone application. This allows the calibration to be adjusted for different fuel types and performance requirements without requiring a traditional ECU flash.

On 93-octane fuel, the Stage 1 controller produces up to 297 HP and 378 lb-ft of torque, while 100-octane fuel allows up to 313 HP and 409 lb-ft of torque.

The system is ready to install and has an estimated installation time of approximately 2 hours.

The CPC supports:

• 91-octane map
• 93-octane map
• 100-octane map

Emissions Legality

CarBahn notes that removing the catalytic converter with a downpipe provides a relatively small performance gain, typically around 11 HP, based on back-to-back dyno testing. Catalyst removal can make it difficult to pass required emissions testing and is illegal in certain applications and jurisdictions.
