YOU MUST HAVE AN HPTUNERS CABLE TO USE THIS OPTION.
This option is perfect for those who have access to an HPTuners cable, or who own one. RPM Motorsports can write you a custom file remotely using our email file service.
Simply purchase this product, and we will reach out to you so that you can email us your current or stock tune. We will rewrite your tune file with our E47 tune and email it back to you quickly. Before installing the tune you will need to make sure that you have LESS than half a tank of premium fuel in your car. You will want to add 6.5 gallons of E85, and fill the rest up with 91 or 93 octane. Before starting the car on the 50/50 blend of fuel (known commonly as E47) you will want to flash the tune file to the car.
On your first startup it is best to let the car sit and idle for a few minutes before taking for a drive. Be careful with the car until you feel comfortable with the new power level, many drivers are surprised by how much torque this tune produces and how much more responsive it makes the car.
If you want to be able to switch between our E47 tunes and our Premium Fuel Stage 1 or Stage 2 tunes, simply purchase both files and feel free to flash between them. Though be sure that all of the E85 is out of the tank before switching back to the Stage 1 or Stage 2 tunes to ensure that you do not run your engine lean.
