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.

SHIFT LIKE YOU MEAN IT

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.

CONFIDENCE IN EVERY SHIFT

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.

BUILT FOR EVERY DRIVE

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?
1

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.
2

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.

Compatible with 2017-2020 DL382 DSG "Gen 1" transmissions only. TCU tune is currently incompatible with all 2021+ "Gen 2" TCU versions. In some rare cases, 2019 and 2020 model year vehicles may be equipped with unsupported Gen 2 variations.

Frequently Asked Questions

Do I need a TCU tune for my Audi A4 or A5?

No. But you’ll want one. iE ECU tunes include custom torque and line pressure strategies, so your car runs properly and safely without it, but the stock transmission still limits shift speed, RPM, and overall performance. The iE TCU tune unlocks faster shifts, higher RPM limits, improved drivability, and full power delivery for a complete, fully dialed setup.

What does the iE TCU tune do?

The iE TCU tune recalibrates the transmission for faster shifts, better gear selection, and improved drivability. It increases clutch pressure, removes torque limits, raises RPM limits, and adds features like AMAX shifting for smoother, faster acceleration.

Does the iE TCU tune make my car faster?

Yes. Faster shifts, optimized gear changes, and removed torque limits keep the engine in the powerband longer, resulting in quicker acceleration and stronger pull through every gear.

What if my Audi has a locked transmission (TCU)?

All 2021+ and some 2019–2020 models have a locked "Gen 2" transmission computer. Our Audi B9 A4 Stage 1 and 2 tunes include custom torque management, allowing full advertised power without a B9 TCU unlock. Compatible with 2017-2020 DL382 DSG "Gen 1" transmissions only.

What is AMAX shifting, and how does it work?

AMAX shifting keeps power flowing through gear changes during full-throttle acceleration. Instead of losing power between shifts, the transmission maintains clutch engagement, keeping acceleration continuous. When activated, AMAX maintains power during gear changes, harder acceleration from a launch, and shaves time off your quarter mile.

Do I need a different TCU tune for Stage 3 or a hybrid turbo?

Yes. Stage 3 and hybrid turbo setups require a dedicated TCU tune with optimized shift scheduling, higher RPM limits, faster shifts, and increased clutch capacity to safely handle the added power.

Can I install the iE TCU tune at home?

Yes. iE TCU tunes are tested across real-world conditions and include safety programming that monitors temperatures and reduces power if needed to protect the transmission.

Is the iE TCU tune safe for daily driving?

Yes. iE TCU tunes are tested across real-world conditions and include safety programming that monitors temperatures and, if ever needed, reduces power to protect the transmission.

What features are included with the iE TCU tune?

Features include faster shift speeds, optimized shift points, increased RPM limits, improved launch control, AMAX shifting, reduced take-off lag, and gear display in both drive and sport modes. These enhancements work together to improve acceleration, drivability, and overall performance.

2018 Audi Q5

I got the cold air intake , stage 1 tune , and TCU. It drives like a whole different car. I am very pleased with the ease of install and performance. Anytime I call or email with a question, someone is always quick to help out.. I had a 3.0 Q8 try to race me at a red light , I as able to beat him by a little bit.!!

ECU & TCU TUNE

It’s a totally different car now. Noticeable power increase and tight shifting. Very happy with my purchase!! I am a little disappointed that the stage 1 tune does not have “crackles” built in but am very happy over all.
