Flashing Your New Tune

Please note: this info is pre-2012. Sorry, we do NOT have any updated info. We have never tuned anything ever. We recommend talking to a tuner for more current information.


Before you start, please make sure that your AutoCal is all up to date and set up for your vehicle. If not Please go through the steps in Updating your AutoCal and Preparing your Autocal.

Open up EFILive Explorer and click on the F3: Data Files tab.

Find and click on the Tune Folder.

Find your new improved tune file and drag it into the tune folder.

When it finishes copying, quit EFILive Explorer and unplug the USB cable from the AutoCal.

Now walk out to your vehicle, plug the AutoCal into the OBD port on the vehicle and turn the key all the way to on.

Press the Down Arrow button (the right one) until you see Prog 1, 2, 3, 4 or 5 and the tune you just copied to the Tune folder of the AutoCal.

Press OK (the center button) and follow the directions. If this is the first time you've flashed this vehicle you will have to go through some additional one-time licensing steps and may have to start over from the beginning after they finish.

After the flashing is finished you will be asked to turn the key off for 15 or 30 seconds. At the end of that time, unplug the AutoCal.

You should now be able to start your vehicle and experience the wonders of your newly improved tune.

Please be careful for a few miles until you're sure that all is well and that nothing unusual or unexpected happpens.
