BMW Gauge Kits and Data Acquisition for BMW 3 Series E90 (2006-2011)

Clear BMW chassis

Please ensure your correct model is selected

Information is one of the most important tools in making your car faster, handle and brake better, and just be more reliable. Supplemental gauges have long been an easy and effective method of gathering and monitoring data on how the engine is performing, cooling system performance, engine tuning, oil pressure and temp, chassis dynamics, and just about anything else you can think of. Race teams employ teams of data engineers that study and articulate changes in the never ending quest of going faster.

Data acquisition and interpretation does not have to be a black art, however. We offer products that collect and present vital information in an easy to understand display. Think of these as smartphones for your car - sophisticated, touch-button operation, easy installation, and immensely valuable.

The Cobb Tuning AccessPort is a flashing tool that installs performance software through the OBD port on your car. No other software is as easy to use and install! If you can program a TV remote, you're over-qualified to install this software. Just plug the AccessPort into the OBDII port under the dash, bring up the AccessPort onscreen menu, select from a variety of engine maps for your desired performance and install. It's that easy. The software is from COBB Tuning - one of the most accomplished software tuners in the business. The Cobb software replaces the conservative factory settings with different maps to make more power.

The AccessPort maintains the sophisticated control logic, refined engine response and excellent driveability of the stock BMW computer while providing impressive power gains and improved performance. Pre-loaded on the AccessPort are engine maps for 91 or 93 octane fuel, and a valet mode, with the capacity to hold up to 100 other tuning files! The AccessPort also saves your stock tune for you to revert back to factory settings at any time. It also has the the ability to download additional maps so that you can run various upgrades with the correct software tune. Additional tunes are available direct from Cobb through their AccessPort manager program (available for PC or OSX). Cobb also provides tech support.

In addition to the performance improvements, the AccessPort includes a variety of other useful tools -
+ performance measurements
+ data logging - up to 10 hours
+ fault code/DTC reading and clearing
+ check/verify performance modifications - measures 0-60 and � mile times and can measure approximate HP

The AccessPort can display boost pressure, oil temperature, pedal position, load, individual cylinder timing, and other engine data channels with the Live Data feature.

If you can program a TV remote, you're over-qualified to install this software. Just plug the AccessPort into the OBDII port under the dash, bring up the AccessPort onscreen menu, select from a variety of engine maps for your desired performance and install. It's that easy. The software is from COBB Tuning - one of the most accomplished software tuners in the business. The Cobb software replaces the conservative factory settings with different maps to make more power. But it's more than just a way of loading performance software... The AccessPort also functions as a data logger and fault code reader . It's a multi-function tool that you will never get tired of picking up and checking out.

Data
Since it plugs into the car's OBD communication port it has unparalleled access to a stream of engine data. It reads and displays throttle position, boost, ignition advance, wastegate duty cycle, mass air flow, intake air temperature, air/fuel ratio, calculated load, and much more. You can also record data for later analysis - up to 10 hours of running data! It also works as a timing meter for 0-60, 1/8 mile, 60' acceleration, 330' acceleration, and 1,000' acceleration time. You can plug the AccessPort into a PC or Mac and view all of this saved data in their program. This information is invaluable for evaluating engine performance and performance modifications.

Diagnostics
With access to the OBD port, the Cobb tuner can also read and reset Diagnostic Trouble Codes (DTCs). This saves you a trip to the dealer or local shop simply to have a fault code interpreted. Now you can pull these codes and get an answer to the problem right away! The code number and a brief description of the code is given so you won't even have to search for it online. Reset the code and you're on your way (unless the code comes back...).

Power
The AccessPort comes pre-loaded with 4 tuning files - Stage 0 (stock), Stage 1 Sport (91 octane), Stage 1 Aggressive (93 octane), and a Valet file. Additional files are available from the Cobb website for things such as an intake and larger intercooler. It can hold up to 100 different tuning files! It also saves your stock original file so you can revert back to stock at any time. The AccessPort maintains the sophisticated control logic, refined engine response and excellent driveability of the stock BMW computer while providing impressive power gains and improved performance. Cobb engineers are constantly revising and tuning their files to extract the most horsepower with the least effect on reliability and drivability. Updated files and new maps for additional modifications are available direct from Cobb.
