FAST CARS DESERVE FAST SHIFTS

Your iE tuned Audi A4 or A5 delivers the gains. The iE TCU Tune puts that power down. By synchronizing shift behavior, torque delivery, and RPM limits to perfectly align with iE Stage 1, 2, and 3 engine tunes, the drivetrain works as one. Faster shifts. Smarter gear selection. Stronger acceleration. A driving experience that feels sharper, more responsive, and fully dialed.

SHIFT LIKE YOU MEAN IT

Fast cars deserve fast shifts. The factory calibration is built for comfort and a smooth ride - characteristics that deliver early shifts, delayed response, and gear hunting when pushed. iE TCU tuning fixes that by rewriting shift logic, increasing clutch pressure, and removing torque limits. The result is fast, decisive shifts that hit exactly when you expect them and stay locked under power. No confusion. No slip. No clunks. Just smooth, fast, and precise shifts that keep you pulling hard through every gear.

CONFIDENCE IN EVERY SHIFT

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. Every change is shaped by driver feedback and proven where it matters most. 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.

BUILT FOR EVERY DRIVE

Unlike tunes that just raise RPM and speed up shifts, iE TCU tuning completely reworks how your transmission behaves in any scenario. Shift points are smarter when you push it and smoother when you don’t. Reduced take-off lag gets you moving quicker, while the gear display keeps you informed in both drive and sport modes. Upshifts and downshifts land exactly where they should. So good, you’ll forget it’s even there.

HITS DIFFERENT

Flat out, no lift. AMAX keeps both clutches engaged during shifts, so power never drops between gears. From launch to redline, acceleration stays uninterrupted and keeps pulling. Push through the kickdown switch while building launch control to unleash the full attack. Faster, harder acceleration on demand where other tunes lift off. This is your unfair advantage.

TCU GUIDE

What TCU Tune should I run?

STAGE 1 & 2: START HERE

Running an iE Stage 1 or Stage 2 ECU tune? The iE Stage 1 TCU Tune unlocks faster shifts, improved acceleration, a 6800 RPM limit, and full power delivery. Perfect your iE Tuned stock turbo A4 with a fully dialed performance drivetrain.

STAGE 3: BIGGER TURBO

Running an iE Stage 3 hybrid turbo setup? You need the Stage 3 TCU Tune. The added power from iE Stage 3 ECU tuning and the Turbo Systems hybrid turbo requires a transmission calibration built to handle it. The Stage 3 TCU features optimized shift scheduling, faster shift speeds, increased clutch capacity, and a 7200 RPM limit to match the turbo’s powerband. Required for all iE Stage 3 ECU tunes.
