Using OZ TUNER - EFI Live Autocal and Explorer

1.  Go to http://www.OZ Tuner - EFILIVE.com/ and download the latest version of the OZ Tuner - EFILIVE version 8 Scan and Tune Software

2.  Connect the AutoCal to the computer via the supplied USB cable

3.  Double-click on the EFI Explorer desktop icon to open the OZ Tuner - EFILIVE Explorer computer program on your PC.

NOTE: You must have OZ Tuner - EFILIVE v8.1 installed to use the OZ Tuner - EFILIVE Explorer program. See the “Downloading OZ Tuner - EFILIVE Version 8 Software/Update” section in these instructions for information on where to download the newest software and updates.

4. When an OZ Tuner - EFILIVE AutoCal is connected to the PC, the AutoCal folder tree should be populated (shown in picture below) and there should be a green checkmark covering the device in the bottom right corner of the screen.

5. The illustration below shows the lower half of the OZ Tuner - EFILIVE Explorer home screen. With the AutoCal already connected to the computer, the program will automatically open the contents of the OZ Tuner - EFILIVE AutoCal, as shown by the red arrow below.
 Installing and Removing Calibrations to and from AutoCal

1. The OZ Tuner - EFILIVE Explorer allows the user to manage the files stored in the internal memory of the AutoCal.

2. To install a tuned calibration from ID via E-mail attachment, download the calibration and save it to a folder. Make sure to keep track of which folder you save the calibration in.

3. Inside the OZ Tuner - EFILIVE Explorer program, select the folder that you saved the calibration in from the windows explorer window (top left window pane)

4. In the window directly to the right of the windows explorer window (top right window pane), any available calibration files will be shown. Click on the desired calibration file(s) and drag them down to the “Tune” folder in the AutoCal explorer window (bottom left window pane). Upon opening the “Tune” folder, the calibration file(s) should now appear in the adjacent window (labeled as #4).

5. If you want to remove a calibration file from the AutoCal device, right-click the calibration file and select “Copy” to copy the file to a different location on the computer and then right-click on the file in the “Tune” folder and select “delete”.

6. The AutoCal can be disconnected at this time. The calibration file is now saved on the AutoCal device.

NOTE: If you get an error while attempting to add a file to the AutoCal, too many files (calibrations and/or data logs) are currently saved on the AutoCal, so you will need to remove files before adding the calibration to the AutoCal.
Using your Autocal on the vehicle:

Turn ignition on, but do not crank.

Scroll down until you see “Read 1”

Once countdown completes, you are ready to flash your truck.

How to flash a custom tune to your vehicle:

Click on the “Full” option of your choice of tune

Choose “Full 1 DSP5_ID”

How to Datalog with Autocal *BBx*

Click ok to the letter/number combo that pops up.

Click ok on “Record Data” to data log and send to us or “Display Data” to verify information for yourself.

Many of the options (PIDs) you see are the options that are available that will help us diagnose any issues you may be having with your truck.
To Verify DSP5 Voltage

Scroll down to “DSP5 Vol”. (as you switch your tunes, this voltage will drop. This verifies that your switch is installed properly.)

To Read and Clear Codes

Scroll down to “Clear DTCs” to clear codes or “display DTCs” to read out any codes you have.
Troubleshooting basics:


Error Code $0281 means there is no power to the Autocal, make sure your key is all the way in the run position (not cranked). Also check cigarette lighter fuse. The OBD port runs off of the same fuse. Replace the fuse and try it again. If code continues to pop up, turn key off for 15 seconds, unplug Autocal, and retry operation. If problem persist, please contact the dealer you purchased the unit from and we will all work to resolve your issue.
