Stillen TruControl ECU Tuner for Nissan Z RZ34 (2023-2026) Plug & Play Inline Tuning Module TCT101001

TruControl was never meant to be static. From the moment the original TruControl was released in 2023, customer response has been overwhelmingly positive. Drivers loved the added horsepower and torque, the ease of installation, and the intuitive app based control. But many customers wanted more insight into what was happening behind the scenes. They wanted to feel the power and understand it.

TruControl V2 is the result of listening.

Same Core Features and Proven Results

You shouldn’t change things that aren’t broke, so we didn’t. V2, like its predecessor, seamlessly integrates the Power Module into the factory wiring harness and fine-tunes crucial parameters, unlocks increased boost pressure, and delivers substantial power and torque gains throughout the entire power band. All in minutes without any special tools, splicing or soldering.

TruControl V2 by STILLEN Inline Power Module also won't void your factory warranty! As long as you remove the product before visiting the dealership for service, your warranty remains intact. So, you can enjoy the benefits of enhanced power and performance without any worries. The TruControl by STILLEN Inline Power Module is your ticket to the easiest and most affordable horsepower upgrade available for your Z. Experience the difference and unlock the true potential of your vehicle today!

Most importantly, the additional power that is enjoyed by thousands already is unchanged. From the factory the Z is rated at 400 flywheel horsepower. On our dyno we saw a maximum wheel horsepower output of 336 horsepower at 6300 RPM*. This is about a 15% drivetrain loss. Great work by Nissan to get all of that power to the ground. After installing our TruControl by STILLEN Inline Power Module the dyno reported back a Max horsepower output of 392 wheel horsepower at 5390 RPM*. Simply by installing the TruControl by STILLEN Inline Power Module on the Z, we were able to gain more than 70 flywheel horsepower*.

Even more amazing than the gains in horsepower are the gains in torque output. As you can see in the dyno the factory torque curve begins to decline at just over 3500 RPM*. At this RPM the stock car produced 338 ft. lbs of torque. The TruControl by STILLEN Inline Power Module is at 393 lb-ft of torque*. Whereas the factory torque curve begins to decline, the TruControl by STILLEN Inline Power Module curve only increases further until reaching its maximum output at 4720 RPM*. At this point the factory output has declined to 323 lb-ft* while the TruControl by STILLEN Inline Power Module has managed to increase to 409 lb-ft of torque*. Truly amazing gains that make the Z an absolutely incredible car to drive.

What Makes TruControl V2 Different

Rather than fixing a problem, STILLEN set out to evolve a proven platform with V2. Working with advanced electronics partners, we completely re engineered the internal hardware to make TruControl smarter, faster, and more capable of growing into the future. The new processing hardware not only improves responsiveness today, it lays the groundwork for expanded data integration through the vehicle’s OBD2 system in the future.

Power delivery itself has also been refined. By leveraging additional engine signals on applicable vehicles, TruControl V2 is able to manage boost with greater accuracy across the RPM range. The result is power that feels more natural and more controlled, delivering strong acceleration without harshness. It is a tune you can feel immediately, but one that remains balanced and smooth whether you are cruising the highway on your daily commute, driving spiritedly on country roads, or tearing down a straight away at your local track.

The physical module has undergone the same thoughtful evolution. Every TruControl V2 unit is sealed in a high quality polyurethane potting compound, creating a rugged, weather resistant enclosure designed to withstand heat, vibration, and the demanding environments vehicles are actually used in. You may not see the electronics inside anymore, but that is the point. They are protected, preserved, and built for long term service.

TruControl V2 represents STILLEN’s commitment to continuous improvement. It is powered by customer input, engineered for the future, and designed to make every drive in your 2023+ Nissan Z more engaging, more informed, and more exciting. This is not a replacement. It is the next step forward.
