Doesn't fit your car (0)
Double-check fitment before buying.
Before you start
- You need the IE tune for your engine and IE's PowerLINK cable (sold separately). The cable reads your car and only flashes the right tune.
- Use the octane you actually buy (91 or 93). You can switch octane or go back to stock any time without paying again.
Steps
Install the software
- Download the drivers and IE Flash Wizard from IE's tuning site and install them on your laptop.
Connect to the car
- Hook up a battery charger. Plug the PowerLINK into your laptop and the OBD-II port under the dash, then turn the ignition on without starting the engine.
Pick your stage and octane
- Let it read the car, then choose Stage 1 (for a stock car) and your fuel octane. Check the credits match and confirm.
Flash the tune
- Press flash and don't touch anything until it's done (a few minutes up to about 20). Warning lights like ABS during the flash are normal.
Restart and drive
- Turn the ignition off and back on when it tells you. The lights clear and the tune is installed. Drive gently at first.
How to know it worked
- No warning lights after restarting.
- Noticeably stronger pull in the midrange.

For:
Safety first
- Park on flat ground, set the parking brake and chock the wheels.
- Never get under a car held up only by a jack. Use jack stands.
- Let the engine and exhaust cool first.
- Disconnect the battery before unplugging electrical parts.
- Wear safety glasses.
- If something doesn't match your car, stop and ask a shop.
Follow your part's instructions and your service manual's torque specs.
