HARMONIZED POWER

FULL POWER ON ANY TRANSMISSION
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.
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 |

3000 RPM |
3200 RPM |
|
AGGRESSIVE |
3400 RPM |
3600 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.
Important note: Transmission tuning is compatible with most 2022+ MK8 models. Some transmissions are equipped with advanced security locks that prevent tuning. If your vehicle's transmission cannot be unlocked, we will provide a full refund for the TCU tune. You can also verify compatibility with your TCU using our easy step-by-step MK8 TCU Unlock Guide.
