If you can, try to restore the default settings (not sure if this feature was removed from the interface or not, though).

Definitely create a thread in the support section of N54tech.com as you will get more help over there.

Feature was removed. Tries that already. I bought the unit used. Previous owner updated the firmware on 8/1/2014 and tuning firmware version 27/15/2
I opened the jb4 box itself and noticed that the diodes are still attached so it is not a G5 ISO. But I'm very sure that it is a G5 board bcz the menu on the steering wheels goes up to 14.
Again I'm not sure if he put the wrong firmware on this box.

We may have found your problem. The newer firmware's are written for G5 ISO only, so he loaded new firmware on an outdated unit that can't support it.

Contact Russell or Terry @ BMS over at N54Tech on reverting to old firmware, or modifying your board to load new firmwares.

Post a link to this thread if it makes things easier, but get a thread started there ASAP. I'm sure you'll get great support from the guys who made the unit over there.

Problem solved. The previous owner loaded the ISO firmware on the unit without cutting out the diodes.
Did that and uploaded the latest firmware again.
The car pulls smooth now in all gears.
2d2e code went away.
Everyone on here and n54 tech knows what the heck they're doing. U guys rock.
