UPGRADE GUIDE

INCLUDED FEATURES

E85 READY
Unlock the power of ethanol! Stage 1 & 2 supports E60-E85 ethanol blends that produce the highest power output due to running cooler and have a higher knock resistance than 91/93 pump gas.

EXHAUST OVERRUN
Stage 2 files add an aggressive exhaust ovverrun/crackle in sport or R modes when you let off the throttle, downshift, or decel from higher RPM. This feature is also available when free-revving in neutral or park. Guaranteed to put a smile on your face.

Exhaust overrun is included with Stage 2 tuning.

REV FREE
A raised engine speed limiter of 7000 RPM gives you more power at higher RPMs. Free-rev your engine in park or neutral with the limiter increased to 6750 RPM.

BRAKE BOOST
Brake Boost gives you a rolling launch. While giving throttle input, use your left foot on the brake to build boost while maintaining your desired speed. When ready, let off the brake for a surge of power and boosted take-off for the competitive edge in a roll racing scenario.

RESCALED POWER GAUGES
Get accurate readings with rescaled factory boost, power, and torque gauges that match your new performance output. We’ve also smoothed out the gauge animation for more precise and refined display readings.

AUTO START/STOP MEMORY
Take control of your driving experience with an auto start/stop button that remembers your preferred setting—even after you turn off the car.

FAN LAUNCH STRATEGY
When launch control is engaged, iE’s Fan Launch Strategy keeps intake air temperatures low by kicking on the cooling fan to give you maximum power from the start.

AUTOPROTECT
Even with the best tuning, unreliable fuel and mechanical failures can still pose a risk to any engine. iE AutoProtect is your engines final defense. This innovative protection programming instantly lowers boost and power then triggers a unique CEL if a dangerous condition arises. Power will automatically restore once conditions read safe. This advanced strategy will save your engine, even in situations where a stock calibration falls short.

THROTTLE RESPONSE
The torque request and throttle maps have been entirely reworked to deliver an ultra-responsive and connected driving experience. Enjoy a sporty throttle with smooth and dependable power delivery.

TCU TUNE

HIGH-PERFORMANCE TRANSMISSION SOFTWARE

HARMONIZED POWER

Unlock the full potential of your iE ECU tune with our matching TCU (Transmission Control Unit) tune. Enhancing shift speeds, removing torque limiters, preventing transmission slip, and introducing adjustable launch control, this upgrade delivers a dramatic improvement in launch power, pulling force, shift responsiveness, and overall acceleration.

• Lightning-Fast Shifts: Further improves acceleration and 0-60 times

• Full Power Unleashed: Removes power-restricting torque limiters

• Adjustable Launch Control: Fine-tune your launch to your setup

• Aggressive Torque Cut on Shifts: Maintain boost between gears

• Always-On Gear Display: Displays the current gear in all modes

• Kickdown Disabled in Sport-Manual Mode: No unexpected shifts

• Optimized Shift Scheduling: Shift strategies for faster response

• Raised Manual Auto-Upshift: Increased to 6900 RPM

• Optional No Auto-Upshift: In manual mode, opt to remove automatic upshifts for total gear control.

Important note: Many 2022+ MK8 transmissions are equipped with advanced security locks that prevent tuning. We recommend purchasing your ECU tune and verifying that your transmission is unlocked before purchasing the TCU tune. Once you own your iE POWERlink, you can easily verify compatibility with your TCU using our easy step-by-step MK8 TCU Unlock Guide.

VARIABLE LAUNCH CONTROL

Get ready for explosive launches with iE’s variable launch control. Choose between three launch RPM settings to dial in the perfect balance of grip and power for your vehicle’s setup. Each setting includes two RPM settings engaged by the throttle position:

• Apply 100% throttle input without engaging the kickdown switch to launch from the minimal chosen RPM.
  
  
• Engage full pedal pressure while activating the kickdown switch to launch with additional RPMs, delivering the most aggressive launch.

LAUNCH SETTING	MINIMUM RPM	MAXIMUM RPM
STREET	3000 RPM	3200 RPM
AGGRESSIVE	3400 RPM	3600 RPM
RACE	3800 RPM	4000 RPM

DRIVING ENHANCEMENTS

The stock transmission tuning often doesn’t meet the demands of performance enthusiasts. iE’s TCU tune fully revamps the transmission drive-mapping strategy, ensuring precise, enthusiast-focused performance for every drive. Enjoy a much more responsive transmission with crisp, fast shifts and buttery smooth power delivery.
