Cobb AccessPort for 335i Announced!

The Cobb AccessPort is a tuning device that I've been using for many years.  It was first released in 2004 for the Subaru WRX, and I've been conducting custom dyno-tuning sessions using the AccessPort since that time.  Even though there are other tuning tools for the Subaru, the AccessPort is my preferred tuning suite.

Last week Cobb Tuning announced an AccessPort for BMW N54-engine cars.  It will come with maps for a couple of different combinations of hardware modifications, and will also allow for custom tuning.  Here at Mach V Motorsports we intend to use the N54 AccessPort on our own car, and will take advantage of it to develop our own calibrations for the car.

The AccessPort has several advantages compared to many of the other tuning solutions that are available for the 335i.  Since it uses the original ECU, there are no wires to hook up other than a single OBD-II port plug.  Once the reprogramming is complete the AccessPort can be removed from the car.  The AccessPort programming retains all the car's factory safety features and limiters -- they are adjusted as appropriate, without having to fool or "trick" the ECU by editing the sensor signals.  The AccessPort can be easily removed and the car reverted to stock at any time, again without doing any physical modification of the car.

This definitely changes the marketplace in terms of tuning tools for the turbo BMWs.  I'm very excited about the AccessPort.  Stay tuned for real-world dyno results!
