Question JB4 Option 1/7 - Does it reset fuel adaptations too?

The official JB4 information thread over on N54Tech says that option 1/7 resets octane, throttle, and o2 sensor adaptations. Does anybody know if this will also reset the long term fuel adaptations?

I'm installing a new low pressure fuel sensor and from what I've read, I need to reset the long term fuel adaptations afterwards. I'd rather not lock my BT cable to my VIN to reset these if I don't need to.

If I do need to use the BT tool, do I just reset adaptations under Engine -> commands-> send?

Thanks!

Good question. I'd like to know as well.
