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.

Factory transmission calibrations include torque limiters that reduce engine power when power limits are exceeded. The iE TCU Tune raises these limits, allowing your engine tune to deliver full power and torque. For models with locked TCUs or customers who don’t purchase the TCU tune, iE’s innovative ECU tune communicates torque from the ECU side, ensuring full horsepower and torque output without relying on a reduced power “Low Torque” file or tune.

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.

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.
