    All your posts so far are very hard to read and comprehend, on a forum it helps to use full words and sentences. You'll get more help if people don't give up reading within 10 seconds trying to understand what you are saying.
    Need official EFILive help, please go here.
    For tuning support please post your questions on this forum (or other auto forums).
    Sorry if I don't respond to your PM, don't take it personal.
