The HKS Launch Technique System is a highly sought-after upgrade for Nissan GT-R owners who demand maximum off-the-line performance. For the 2019 model year, the GT-R already boasts impressive launch capabilities thanks to its advanced all-wheel-drive system and twin-turbo V6. However, the HKS system fine-tunes the launch control parameters to reduce lag, optimize boost, and deliver consistently faster 60-foot times. In this comprehensive guide, we break down every dollar of the roughly $1,200 total investment, explain what each component does, and provide context to help you decide if this mod is right for your build.

What Is the HKS Launch Technique System?

The HKS Launch Technique System is an electronic controller that interfaces with the GT-R’s engine management to govern how power is delivered during a standing start. Unlike the factory launch control, which can feel inconsistent or overly aggressive, the HKS unit allows the driver to adjust boost pressure, RPM holding, and torque ramp-in through a simple switch or smartphone app. This enables precise tuning for different track surfaces, tire compounds, and ambient conditions.

Key features include:

  • Adjustable launch RPM – set between 3,500 and 4,500 rpm depending on grip.
  • Boost-by-gear capability – tailor boost in first and second gear for traction management.
  • Flat-foot shifting support – keep the throttle pinned during upshifts for uninterrupted acceleration.
  • Data logging – monitor launch parameters to refine your technique.

Detailed Cost Breakdown

Below we expand each line item from the total estimate of $1,200. Prices reflect current market averages for U.S. customers purchasing from authorized HKS distributors and using a reputable performance shop.

1. HKS Launch Technique System Kit – $800

The base kit includes the control module (part number 41007-AK013), a wiring harness, mounting bracket, and touch-screen display or button interface. Pricing can vary slightly depending on whether you choose the standard digital controller or the updated Bluetooth version. The kit is designed specifically for the R35 GT-R (2009–2021) and includes all necessary connectors to splice into the ECU and CAN bus.

Buying from an authorized dealer like Evasive Motorsports ensures you receive a genuine unit with warranty support. Avoid unbranded clones – they often lack proper firmware and can damage the ECU.

2. Installation Labor – $300

Professional installation by a shop experienced with R35 GT-Rs typically runs two to three hours at $100–$150 per hour. The job involves routing the harness through the firewall, connecting power and ground, tapping into the throttle and brake pedal sensors, and mounting the controller in a convenient location (such as the center console or glovebox). A specialist will also verify that the system does not interfere with factory safety systems like VDC and ABS.

Choosing a shop that has performed this exact install before reduces risk of wiring errors. Expect to pay a premium if the shop needs to fabricate custom brackets or if your GT-R has aftermarket engine management that complicates integration.

3. Tuning Services – $100

The HKS system requires a base calibration to match your vehicle’s current tune. Many shops include a basic flash or adjustment of the launch parameters as part of the labor cost, but we budget $100 separately for a dedicated tune session on a dynamometer. This step ensures the system’s boost-by-gear and RPM limits are safe for your engine’s internals and fuel system.

If you already have a custom ECU tune (e.g., from Cobb Accessport or EcuTek), the tuner will merge the HKS settings into that existing map. For stock ECUs, the HKS piggyback controller works independently, but adjustments to fuel and timing are still recommended to prevent knock during high-load launches. Cobb Tuning’s ProTuner network includes many shops familiar with HKS Launch integration.

4. Miscellaneous Parts and Supplies – $50

These small costs add up: wiring supplies (solder, heat shrink, zip ties), fused add-a-circuit for a clean power tap, dielectric grease for weatherproof connectors, and optionally a mounting plate if you prefer to locate the controller in an alternative spot. Some installers also recommend replacing the brake light switch if the factory one is worn, as it must provide a clean signal to the HKS module. A few dollars for vacuum caps or boost hose may be needed if the kit requires a pressure reference. Budget $50 to cover these incidentals without surprise trips to the auto parts store.

Total Cost and Value Analysis

  • Kit: $800
  • Labor: $300
  • Tuning: $100
  • Supplies: $50
  • Grand total: $1,200

Compared to a full engine build or transmission upgrade, $1,200 is a modest investment that directly improves one of the most critical performance metrics: the launch. For street-driven GT-Rs, a consistent launch means quicker 0–60 mph times (often dropping from 2.9 seconds to 2.6 seconds with proper traction) and more confident merging into traffic. On the drag strip, the system can shave 0.2–0.4 seconds off the quarter-mile by eliminating wheel-hop and allowing the driver to focus on shift points.

Performance Expectations

With the HKS Launch Technique System properly calibrated on a 2019 GT-R (stock turbo and fuel system), real-world gains include:

  • Zero to 60 mph: 2.6 – 2.8 seconds (factory is 2.9 – 3.1 seconds).
  • Quarter-mile trap speed: +2–3 mph over factory launch control.
  • 60-foot times: Consistently 1.45–1.55 seconds on street tires, down from 1.65–1.75 seconds.
  • Improved repeatability: The HKS system delivers the same launch every time, reducing driver error.

Note that results depend strongly on tire condition, ambient temperature, and elevation. The system is not a magic bullet for poor traction; you still need sticky tires and a prepared surface.

Installation Considerations

DIY vs. Professional

If you have solid experience with automotive electronics and wiring diagrams, the HKS system can be installed in a weekend. The main challenge is finding clean pass-throughs for the harness and ensuring all connections are weather-resistant. However, any mistake can cause drivability issues or damage sensors. For most owners, $300 is cheap insurance.

Pre-Install Checklist

  • Update the GT-R’s ECU to the latest stock calibration (if applicable).
  • Inspect all drive belt and transmission fluid condition – weak components may fail under repeated hard launches.
  • Verify your battery terminals and ground points are clean – the HKS module draws minimal current but needs stable voltage.
  • Have a spare set of spark plugs on hand; the adjusted launch RPM may expose pre-existing ignition weakness.

Alternatives and Complementary Modifications

The HKS system is not the only launch control solution. Alternatives include:

  • Motiv Motorsport LC3+ – similar functionality with a more aggressive boost ramp.
  • Syvecs adaptive launch control – expensive but works with standalone ECUs.
  • EcuTek RaceROM launch control – if your tuning platform supports it, this can be a software-only solution.

To get the most from any launch control system, consider these supporting upgrades:

  • Transmission cooler – sustained hard launches heat the gearbox oil quickly.
  • Upgraded rear differential mount – reduces wheel-hop.
  • Drag radial tires – hook the power from the higher launch RPM.

Maintenance and Longevity

The HKS Launch Technique System itself is a low-maintenance electronic device. Check the wiring harness periodically for chafing or corrosion, especially if the car sees rain or track use. The controller display can be updated via USB if HKS releases firmware patches. Over time, the launch button or switch may wear; replacements are available for around $20. Also, because the system bypasses some factory torque limits, you should monitor transmission and transfer case health – premature wear is possible if you use the launch control every time you drive.

Frequently Asked Questions

Will the HKS system void my factory warranty?

Any modification that alters engine management parameters can potentially void warranty coverage on related drivetrain components. For a 2019 GT-R, the factory powertrain warranty may already be expired or close to expiration; check with your dealer. Many owners choose to remove the unit before dealer visits to avoid questions.

Can I install the system on a GT-R with a built engine?

Yes – in fact, built motors that can handle higher boost levels benefit even more from the precision launch control. The HKS system adapts to whatever power level your engine makes.

Does the system affect daily drivability?

No. When the launch control is not engaged, the HKS unit remains passive. The GT-R drives exactly as stock – no change in idle, cruise, or normal acceleration.

What if I get a CEL after installation?

Minor diagnostic trouble codes (e.g., accelerator pedal position sensor plausibility) may appear if the wiring is not shielded. Proper routing and termination prevent this. If a CEL appears, start by checking connections and grounds.

Final Thoughts

For $1,200, the HKS Launch Technique System delivers a measurable and repeatable improvement in one of the GT-R’s most celebrated attributes – its ability to launch hard. Whether you are chasing lower ETs at the track or simply want the thrill of a perfectly executed standing start on the street, this upgrade is well worth the cost when professionally installed and tuned. Pair it with quality tires and regular maintenance, and your 2019 GT-R will reward you with launches that embarrass far more expensive machinery.
