Hi dmnc02 , as there as a question about this in this thread, I am not entirely clear about your comments. In general, if the dealer update performs a similar cdDeploy in the final flash phase, then any ECU being updated would have all of its FDL reset according to the VO:
1. if FA was modified and written to the car, then the VO coding is done using that modified written FA to car, right? That's what I came to in my post #15 here. So what happens when a user writes the modified FAs for NGHB post flash?
2. if FA is saved offline but not written to car, then the VO coding is done using the original FA and all changes are lost and the user has to VO code using the saved FA and re-code.

Thanks!
