Cobb AccessPort2 firmware update: v1.0.1.0

The firmware update for the Cobb Accessport went smoothly. The nice thing about these updates is that you don't have to uninstall the AP from the car to do the update. The biggest change is the addition of the Performance Tests....

After I installed the update, I went out for a drive. There are two tests you can do: 0-60 and 1/4 mile. The AP records the time and speed at various intervals and when the criteria is met (speed = 60 mph or distance = 1/4 mile) the test is completed and the results are shown. If you happen to decelerate before the criteria is met, the test will terminate and it will show you the results it got.

These are the changes for this update:
  • Added additional screen when no DTCs are found.
  • Added 0-60mph and 1/4mi performance tests.
  • Fixed screen refresh issues related to the Map List, DTC list, and flash completion status.
  • Increased animation responsiveness.
  • Improved COBB USB to OBD Cable detection.


  1. Hi it's CHarles - still in California. How were the stats on the performance test?

  2. It's mounted on the air vent. I thought about Velcro and I even bought some strips, but I think ultimately this will be more secure.

    It fits great especially now since I routed the ODBII socket behind the dash.

  3. Hey, Charles! How's the surf? :0)

    I haven't had a chance to do a "real" test yet because it's hard to find the right conditions. Once the AP detects deceleration, the tests end.

    What I'd really like to do is go out to Mission and try it out on the track and compare numbers.

  4. I know this post was up a while ago, but I am trying to find a way to mount my new access port. Where did you get the vent clip, and what model is it? Thanks.

  5. It's a "Type S" cell phone holder that I bought from Canadian Tire. In the USA, it's available at Target Stores. The price is between $6 (USD) to $12 (CAD).
