Laptop "Online" Communication With ECU:
Next to the “Toolbox” button, is a button to indicate the following status of ECU/laptop communications.
Offline: Is shown when the ECU is not powered or the USB cable is not connected.
USB Link: Is shown when the ECU is powered and USB connectivity is established.
However, the user has not chosen to select the “Online” mode,
and the Laptop & ECU are not communicating with each other.
Changes made at this time on the laptop, are not being updated in the ECU.
Online: Is shown when the Laptop and ECU are communicating.
At this point, changes made with the laptop are real-time updated in the ECU.

"Get From ECU" & "Send To ECU" - ECU Sync window:
When you connect a laptop and go "Online" with the ECU, you first want to click "Get From ECU". This updates your laptop with the latest
ECU "state of tune". If you click "Send To ECU", you overwrite all the Learning the ECU has performed since the last time that laptop was
connected (because you're not sending the latest, up to date values to the ECU). The only time you should click "Send To ECU", is if
you're just sending a Global File change to the ECU
and you haven't driven the vehicle since the last time the laptop was connected.

Creating, Naming & Saving a Global File (Global Config Directory):
You should name your Global File and save it in the EFI software. See below:
Open the "Help" Contents ("Help" drop down menu), and read "Step-By-Step Beginner's Tuning".
Or, at least read the "Quick Start Guide":
http://documents.holley.com/techlibr...r10546rev1.pdf
IF creating a new Global File Name (as opposed to just saving a change in an existing GF), it's much easier to click "File",
"Save Global File As...", delete the Global File Name shown and just type in the new name you want without any backslash.

Emailing Global Folders/Global Files (V4) & Datalogs:
Your Global Folder
and/or Datalogs can be emailed to yourself or other forum members. Click on their username, "View Profile", "About Me"
& "Download vCard" for their email address. When emailing a Global Folder/File or Datalog, use your email's 'attachment utility' function and
Browse through your computer's "Documents", "Holley", "HEFI" & "Global Folders"/"Global Files" (V4) or "Datalogs". V3 & earlier: Then right
click on your Global Folder and Send To "Compressed (Zipped) Folder". Then select the zipped folder and attach it to the email. V4 Global
Files & Datalogs (all versions) aren't required to be "zipped"; simply select & attach it to the email. The recipient now has your entire GF
or Datalog in one easy step. If it's zipped from email, so download it to your Desktop (or wherever your PC saves it to), and unzip it.
Then "Cut & Paste" the GF into "Holley" "HEFI" "Global Folders/Files" directory (located in Documents).

ECU Date & Time:
When you go "Online" with the ECU, the option to "Sync ECU Time" (ECU RTC) is at the top of the ECU Sync window. Then cycle the ignition key off/on.
