Your iE tuned MK8 Golf R or 8y S3 delivers serious power gains. The iE TCU Tune puts that power to the ground.

Smarter gear selection. Stronger acceleration. A driving experience that feels sharper, more responsive, and fully dialed.

We don’t rush it, we safeguard it. iE TCU tunes are developed over months and validated across real cars and real driving conditions worldwide. Clutch pressures are carefully increased and controlled to prevent slip without overstressing components, while advanced safety logic reduces power if temperatures climb too high. Fast, precise shifts. Full power when you want it. Protection when you need it.
When others stop at just shifting faster, we are just getting started. The iE TCU Tune was shaped through extensive real-world testing and driver feedback to deliver a transmission that feels natural, predictable, and fully dialed. Shift points are precise and smooth, with upshifts and downshifts that land exactly when they should. Reduced take-off lag gets you moving quicker, while the display keeps you informed of your current gearing in every drive mode. So good, you’ll forget it’s even there.
