That's good to know - just got my USB cable yesterday so I will be playing with the software real soon.

I'd love for BMS to develop some sort of hardware bypass that will allow you to just uplug the JB4 while leaving the wire packs connected (the car won't start if the JB4 isn't plugged in). Removing the JB4 is easy - removing the wire packs is a PITA.

Do doubt, they can also remove the lid to the E-Box and have a look. I wonder if they ever do such things without a reason? I had left mine in MAPP1 so they couldn't read the OBD and this prompted them to have a look in the box to see what the issue was. I am sure they already knew before actually opening it up. I imagine that if you take you car in for something totally non related to this they would have no reason to be searching for a JB4, but who really knows?

+1 for JB4; took a Porsche buddy for a spin at MAP 5 and scared him shitless......Takes a little while to remember and enter commands without the cheat-sheet in the car....

I was looking at the jb4 or the cobb. There seems to be a lot of people running the jb4 setup with great results. Was wondering if anyone has any first hand experience with cobb accessport? From what I've read i like the easy of the cobb but it is a bit more then the jb4. So is it worth the money. This tune will be all that i would be adding since I've got a bit of warranty time left.
