I've been trying to connect to the control function in the DVT section, but every time I hit activate it gives me a no reply message. I can connect to the ecm to scan and log? I don't have the build numbers in front of me but the last time I updated was a year ago. Any info would be appreciated. And my tuning laptop is a 2004 unit thats pretty much trash so it might be my problem. Just wandering if there's any other things I could check, before I delete and reinstall efi live program.
