Initial Setup Instructions
Step 1: Create a folder on your computer for tuning files.
We encourage you to create a separate folder, either in your documents, desktop, or whever you prefer, so as to be able to keep all of your tuning files in a central location. To do this, navigate to your desired location, right click on an open area and select "New Folder". Name the folder "Tuning Files" and press enter.

Configure AutoCal for logging and file retrieval
Options File - Download the set of AutoCal files and copy the contents to your Tuning Files folder for usage. To do so, open this Options file and your Tuning Files folder concurrently and drag the contents of the Options file to the Tuning Files folder.
Open the EFILive Scan and Tune software and click the "F5: Black Box Settings" link or "F5: BBX" icon on the left.
Show Example
Click the Open button and navigate to your Tuning Files folder.
Show Example
Select the options file that was previously downloaded that corresponds to the vehicle you are wanting to tune ("Options E38 4spd", "Options Gen3, Vortec", etc). All 2007 and newer trucks GMT-900 trucks, 2007 and newer Corvettes utilize the E38 controller. 2005-2006 LS2 vehicles utilize the E40 controller, 2007-2009 Trailblazer SS utilizes the E67 controller. All 99 and newer LS1 vehicles and 99-06 trucks utilize the Gen3 controller. Do not click the first file that pops up and is listed as just "Options". That is a sample file that is included with the EFILive software and will not be beneficial. You must navigate to the files that have been downloaded and select the correct file for your vehicle. For other vehicles or any questions, please contact us directly at
[email protected].

Program the selected set of options into the AutoCal by pressing the programming button. This process may take a few minutes to complete. The 60-80% value indicated on the Program button is not important.

There are pictures of the "show example" but don't load up when I copy and paste...I have gotten to where I can do the program "options" but then when I go out to try and connect it to the Tahoe, it will not power up. I also tried connecting to the Tahoe while being powered by the laptop and I get a "ERROR: $0281"
is it supposed to draw power from the truck to run?
