**Etunes ARE NOT A QUICK PROCESS! If your looking for a quick turn around I would suggest scheduling an in house dyno appointment. We will try to send revisions once per day during the week after our scheduled dyno tunes here in house. If we run out of time that day we will send your revisions the following business day. We will try and have your tunes finished as quickly and efficiently as possible but if you're looking for a 1-2 day process this IS NOT the option for you. If there are any existing issues with the car when we start your tune this will delay the tuning further and we are not responsible for any time delays while you fix the issues. We do not send revisions Friday-Sunday. We do not offer same day e-tuning services at this time. Please contact us through email only throughout the etuning process, you do not have to call to check on the status of your tune, we are working on them. If you have any questions please email them and we will answer when we work on the etunes in the evening.

What Do I Need for an E-tune?
You will need to have an Uprev Flash cable along with the standard Uprev License and ARC License. If you do not already have your own cable they can be purchased with the links below. If you already have a cable and just need the licenses they can be purchased with the links below.
Uprev Standard Flash Cable -- (Just the Cable)
Uprev Standard Flash Cable and Licenses -- (Cable, Uprev License, ARC license)
Uprev ARC License - (For those who already have their own cable)
Uprev License -(For those who already have their own cable)
You must also have the Uprev Software Downloaded onto a windows compatible laptop equipped with a USB port. Software can be downloaded here .
How Do I Add Licenses To My Cable That I already Have?
If you have purchased licenses to add to an existing cable that you already have, open your Uprev software on the laptop, plug in your Uprev cable that you will be using to tune the car. Once the software recognizes the cable is plugged in you will be able to click on the red icon that says cable managment. Once you open that a new window will open and you can click the License report icon. Save the file to your computer and email that file to us at firstname.lastname@example.org. Once we have your file we will have Uprev allocate your licenses to the file and we will email you a new file to update your cable with. To update you cable please click on Cable Managment again and select Update License, select the new saved file that we emailed back and click submit. If you follow the steps correctly you will see your licenses allocated on the main screen in the Uprev Sofware and It wills say 1 Uprev licenses and 1 ARC license on cable.
I Already Have Everything I Need Whats Next?
Once you have purchased everything you need and downloaded the Uprev software please click here ( Uprev Etune ) and checkout on our website to pay for your E-tune. Please read the Uprev User Guide beforehand to familiarize yourself with how everything works. Once we have received payment we will be emailing you for your mod list as well as ECU Part Number. Your ECU Part Number can be found once you have opened the Uprev sofware and plugged your cable into the vehicle and the laptop. See below
Once we have your mod list and ecu part number we will email over your first tune file. When you receive the file please download it to your laptop and store it somewhere that is easily accessible. Plug the cable into the vehicle and the laptop and open the Uprev software. Once the cable has connected it will say ECU Ready. You will see more square red buttons light up once the cable is connected. To flash the base tune onto the car select Flash Tune file, your computer files will open and select the downloaded file we emailed over and submit.
Where it says ECU ready will then tell you instructions on what to do with the key while the software is flashing onto the ECU. Please be sure to follow the instructed actions when prompted. You will notice your radiator fans turning on during the flashing process, this is normal. Once the process is complete and the fans turn off your car now official has a tune.
Logging and Tracing
Once your car is flashed with the base tune we will need you to log some parameters while driving under different conditions and send us back the data so we can make the adjustments needed to the tune file. One of the red buttons should say logging and tracing. This is what you want to click to open the logging software. Along with your tune files we will also request what kind of logs we would like to receive back. These can vary on a car to car basis so please read the email thoroughly. Once you have clicked on the logging button you will see this screen
On the right hand side you will see the data parameters that can be checked or unchecked. Please select the following:
AFR Bank 1 and Bank 2
AFR correction Bank 1 and Bank 2
Base fuel schedule
Engine speed (RPM)
Ignition timing advance
Hi Det flag
Throttle position (either one)
Some of these parameters will not be available for some models so check as many as are available.
The red circle button at the bottom of the new window is the record button. When you are ready to start recording your log you will simply click the red button to start and to stop. Once you have stopped recording you need to select File and save. Please send back the requested saved logs through email to email@example.com. Once we have received the logs we will make the required adjustments and send back a request for new logs and the updated file. This will continue back and forth until the tune is complete. Typical turn around time for each new file is 1 business day. We send out etunes at the end of each business day after we finish our dyno appointments here at the shop. This can vary due to work load but we will try our best to get your tune finished as quickly as possible. Forced Induction tunes do tend to take more time so please keep that in mind. We do not send tunes over the weekend unless previously discussed so please plan accordingly.
