Can someone here provide me step by step process of installing Cobb accessport? I will do the stage 1 91 octane one hopefully today. Much appreciated. Thanks

For the current generation of Cobb Accessport, once the tune/map is installed, does the unit have to remain connected in the vehicle or is that up to you?

Years ago I had a previous gen Cobb Accessport for a Subaru STi Limited, and once you installed the tune/map, the unit was disconnected and stored away.

It's up to you. You can leave it plugged in to use the gauge feature and data logging if you are into that or just store it away. Mine is stored away.

Excellent, good to know. I was wondering about this looking at the current Accessport version. If I had one, I'd just want it disconnected and stored away as well. Thanks!

Don't have a battery charger. How long it takes for tuning to completion? My gts only has 2300 miles so think battery is pretty new. Thanks

From what I remember, it was around 15 minutes as it has to copy the existing file onto the Accessport first before flashing the new map. I strongly recommend you connect it to a battery charger and make sure you turn off the interior fans and radio during the process as if for some reason it dies during the process, you could brick your ECU. Contact Cobb if a plug into the wall charger like the CTEK one would suffice. You might as well have one of those on hand anyways.

Ok thanks. Bricking would be awful.

I would be shocked if 15 minutes kills the battery.

Cobb AC is very strong on their recommendation on this issue about hooking up a battery charger.

Still would be shocked if the battery dies in 15 minutes...

There must be reasons outside of the battery going dead that are involved with their recommendation.

Cobb made the same recommendation for the installation of their Accessport program in my BMW 335i.

I don't think they believe that the installation process will necessarily cause your battery to go dead. I think they recommend this simply because they want to avoid any possibility of a loss of power during the installation process. The installation process is fully dependent on the availability of a source of electricity and, if your battery is not fully charged, there is a possibility that there may not be sufficient power to complete the installation.

Any loss of power during the process would probably result in the corruption of the ECM due to the loss of the saved image of the ECM and the failure to install the Cobb program in place of it resulting in the need to replace both the ECM and the Accessport device, neither of which I believe is covered by Accessport's warranty if the cause was your failure to take proper care to insure that your battery was fully charged and placed on a battery charger during the installation as recommended.
