California Residents: Prop 65 Warning

Non-Emissions Related

This product is either entirely unrelated to an emissions-controlled engine, or we believe this product does not affect vehicle emissions or any emission control devices on the vehicle it is intended for, that would be subject to any US State or Federal emissions standards. International users outside of the United States should act in accordance with their local laws and regulations.

Infiniti Q50 and Q60 Enthusiasts are going to be really high on this LSD! Wavetrac is bringing quicker acceleration and faster cornering to the Infiniti motorsports market. The Wavetrac R190 LSD’s ability to bias under ZERO to LOW load situations is what makes it superior to everything else on the market. Wavetrac’s manufacturing tolerances and finish requirements meet or exceed all OEM standards. Wavetrac® differentials are built in American plants operating to ISO9002 and TS16949 standards.

How is Wavetrac Different?

To best understand how the Wavetrac® is truly different from the other gear differentials on the market, you first have to understand the primary problem that the Wavetrac® solves.

The problem: Loss of drive during zero or near-zero axle-load conditions.

Zero axle-load is a condition that occurs during normal driving, but creates the most noticeable problems when driving in extreme conditions. Zero or near-zero axle-load is the condition that exists when there is ‘no-load’ applied through the drivetrain, when one drive wheel is nearly or completely lifted (often in aggressive cornering). It also occurs during the transition from engine driving a vehicle to engine braking and back, even with both drive wheels firmly on the ground.

Here’s how that loss of drive hurts you:1) If you lift a wheel, all gear diffs except Wavetrac®, will NOT power the other wheel.2) During the transition from accel to decel, all gear diffs except Wavetrac®, do nothing.Why does this happen?

All gear LSDs work in basically the same manner: they divide the drive torque between the two axles, applying drive to each side, up to the available grip of each tire. The amount of drive torque one wheel can get over the other is described as the bias ratio, a measure of the torque split across the axle.Standard, open differentials have a bias ratio of 1:1. They can only apply as much drive torque as there is available traction at one wheel. When one wheel loses grip, the total available drive is lost as well (at a 1:1 ratio). All your power goes out the slipping wheel – along the path of least resistance.Torque biasing differentials offer increased bias ratios over open differentials. For example, if a diff has a bias ratio of 2.5:1, then it can apply drive torque to the wheel with the most traction (gripping wheel) at 2.5 times the traction limit of the wheel with the least traction (slipping wheel). This is a significant improvement over an open diffs most of the time.The problem is that when one tire has LITTLE or NO grip (zero axle-load), the other wheel gets ZERO DRIVE, because (basic math here): 2.5 x 0 = 0.Lift a wheel (or substantially unload a wheel) and you get zero axle-load on that side – that means that during the time the wheel is unloaded, the typical diff will NOT power the wheel that’s still on the ground. No matter how high the bias ratio, you get no power to the ground.

During the transition from accel to decel, where you have near zero torque on the axle, even if the wheels are on the ground, the typical diff is unable to begin applying drive torque until AFTER the zero torque condition is over. While this condition is generally short-lived, the fact that most diffs can do nothing during that time means that there will be a delay once the zero torque condition stops – creating a reaction time in the driveline.

BENEFITS

  • Innovative: Patented Wavetrac® design automatically improves grip in low traction conditions. This feature is truly innovative and unlike any other torque biasing diff design.
  • Superior Materials: 9310 steel gears run in case-hardened billet or forged steel bodies. ARP® fasteners used throughout.
  • Maintenance Free: As supplied new, the Wavetrac® differential will perform a lifetime of service without maintenance or rebuilds.

APPLICATIONS

  • 2017+ INFINITI Q60 / RWD and AWD 2.0T / RWD and AWD 3.0T
  • 2014+ INFINITI Q50 / 2WD and AWD 2.0T / 2WD and AWD 3.0T / 2WD and AWD 3.7L

NOTES

  • This product requires professional installation by a qualified driveline technician using calibrated specialty service tools to properly shim the differential carrier and gears to achieve appropriate gear lash and mesh. Failure to do so may result in unwanted or excessive noise or whine, or damage to the carrier, housing, gears, etc.
  • Use Motul Gear 300LS 75W-90 Differential Fluid

Application(s):

2017+ INFINITI Q60 with 3.0L Twin Turbo VR30 (Various Submodels) | 2016+ INFINITI Q50 with 3.0L Twin Turbo VR30 (Various Submodels)

The Syvecs Infiniti Q50 / Q60 (VR30) AWD Controller with AMS Calibration File opens up new possibilities not known to the platform before. Unlock the true potential and capabilities of your AWD system with this standalone plug ‘n play AWD/4WD/center diff controller. By fitting a Syvecs AWD Controller with our AMS Calibration File, we provide users with four on-the-fly selectable AWD control strategies resulting in improved stability and acceleration performance for a range of driving conditions. You can also connect our optional Auto-Shift wire giving you an exceptionally accurate, user-adjustable, upshift point selector.

  • AWD Mode Switching Allows for 4 AMS Optimized Strategies to be Switched on the Fly
  • Improved 0-60 and 1/4 Mile Times via Increased Torque Applied to the Front Wheels
  • Burnout Mode Allows for Tire Heating at the Drag Strip, and Dyno Usage
  • Avoids “AWD High-Temp” Warning — No More Limp Mode!
  • Increased Stability in Adverse Weather Conditions
  • Fully Adjustable Auto-Shift Functionality Enabled

The OEM controller that comes installed from the factory in your Q is locked down and not user adjustable. By simply fitting the Syvecs Infiniti Q50 / Q60 (VR30) AWD Controller with AMS Calibration File, a whole new level of control becomes available. This unit allows users to optimize control and provide the best performance available from the powertrain. The Syvecs controller replicates all the OEM CAN information as well as pulls from numerous sources of sensor data via the OEM CANBUS such as Steering Angle, Brake Pressure, RPM, TPS, Lateral G, Yaw, Long G, Speeds, Temperatures, and mode switches. All these data points are essential for calculating precise AWD control strategies.

AMS Calibrated AWD Mode Switching

The Syvecs control module and software allows us to configure four separate AWD mode strategies that are able to be selected on-the-fly by the driver. The adjustments require no laptop or phone app, and are easily and quickly controlled via the factory Drive Mode Selection toggle switch.

  1. Sport & Sport+: 100% AWD application for improvement in straight-line acceleration
  2. Standard: Normal driving mode with optimized stock-like AWD control
  3. ECO: RWD/open differential for increased fuel efficiency and less wear on components when driving straight and without wheel slip (AWD will still engage in a high slip scenario and is not completely disabled for improved safety)
  4. Snow: Increased AWD center diff lock from a standstill, AWD lock optimized for increased stability when turning or stopping

Burnout Mode for the Drag Strip

When you’re at the track trying to set world records, you need every advantage you can get. By allowing the rear half of the AWD system to essentially decouple from the front, Burnout Mode allows for 100% of the engine power to be directed to the rear wheels. When the driver activates the emergency flasher (hazard) button, the system is activated, allowing for the driver to perform a burnout to heat up the rear tires while at the drag strip.

Auto-Shift Feature for Perfect Shifts

Accurate shifting is just as important when racing as your horsepower number. Customers who want the highest level of accuracy in their shift timing can opt to wire in the supplied Auto-Shift feature with our included instructions. This Auto-Shift functionality will “pull the paddle” for you resulting in consistent and optimized wide open throttle upshift points and is pre-programmed with our AMS Calibration File. This is particularly useful with high power applications as drivers won’t pull the paddle quick enough in the lower gears and miss the optimal shift point or hit the rev-limiter. Serious racers can even dial in the exact RPM shift point they need via a PC connection as this feature is fully user adjustable. Auto-shift is active when wide open throttle, in manual shift mode, and when configured engine/vehicle speed thresholds have been met.

Built-In Safety Precautions

The AMS Calibration File for the Syvecs AWD Controller features built-in Limp Mode protection options for large slip, high current, and high temps to warn the driver but keep AWD active, unlike the OEM controllers which shut down power — not ideal for cars with high horsepower! We’ve taken our years of motorsports experience and calibrated our pre-programmed Limp Mode safety protocol to engage for the following scenarios:

  • Large amount of wheel slip detected (front to rear). This will prevent damage to your vehicle’s AWD Unit (center differential).
  • High AWD electrical current fault. This can be an indication of failing wiring or AWD Unit.
  • High AWD Unit temperature. Vehicle will still illuminate a warning light but AWD remains active, unlike the OEM controller which shuts down power.

Syvecs VR30 AWD Controller w/ AMS Calibration File INCLUDES

  • AMS Calibration File Pre-Loaded to Controller
  • Syvecs AWD Controller For Infiniti Q50 + Q60
  • Syvecs Plug ‘n Play Harness
  • Syvecs USB Cable

PRODUCT NOTES

  • Auto-Shift works for vehicles with and without paddles, and can be wired in at the end-user’s discretion. Instructions for wiring to both vehicle types are included.
  • Failure to use Burnout Mode properly can cause serious drivetrain damage. Do not engage or disengage mode while wheels are moving. The vehicle must be at a complete stop, with zero wheel spin, when activating or deactivating mode.
  • Changing calibration settings is not recommended unless done so by an experienced tuner. Calibration support and/or technical information to implement changes is not included with purchase.
  • In order to calibrate the Syvecs AWD Controller software for your specific vehicle, we require your Q50 or Q60’s model year. Please contact our Customer Support team to provide this information as soon as possible to avoid shipping delays.

Application(s):

2017-2022 INFINITI Q60 (incl. All Submodels) – RWD and AWD – 2.0T, and 3.0T | 2014-2024 INFINITI Q50 (incl. All Submodels) – RWD and AWD – 2.0T , 3.0T , 3.5L Hybrid, and 3.7L

The AMS Performance Q50 & Q60 Rear Limited Slip Differential allows for quicker acceleration and faster cornering, no matter the road conditions. The Infiniti Q50 and Q60 as they come from the factory utilize an “open” differential with no ability to lock or reduce slip between the left and right wheels. This unequal distribution of power causes massive wheel spin and loss of traction for one of the tires. To rectify this, our team has designed a helical type LSD constructed of HRC60 hardened 8620 forged steel, allowing for a mechanical reduction in slip between the two rear wheels. Put simply, the AMS Q50 & Q60 LSD allows the rear wheels to operate in unison, improving traction. The best part of the AMS Q LSD is its refined road manners, with no clunking, binding, or chatter that you would normally experience with other types of differentials.

  • Improved Traction for Both Straight Line and Cornering Performance
  • Helical Design for Quiet Operation – No Chattering!
  • No Clunking or Binding During Low-Speed Vehicle Operation
  • Zero Additional Maintenance Compared to OEM
  • HRC60 Hardened 8620 Forged Steel for Long Lasting Reliability

Product Notes

  • This product requires professional installation by a qualified driveline technician using calibrated specialty service tools to properly shim the differential carrier and gears to achieve appropriate gear lash and mesh. Failure to do so may result in unwanted or excessive noise or whine, or damage to the carrier, housing, gears, etc.
  • Use of Motul Gear 300LS 75W-90 oil is recommended.

Our Race Winning Experience Creates Higher Standards

All of our built engines are individually handcrafted at AMS using the same care as the ones found in our world record setting race cars. When you choose an AMS engine you are investing in the knowledge gained from assembling thousands of race engines over the past 25 years. Just like in our 2800+ WHP ALPHA OMEGA Huracan, every motor is balanced, blueprinted and assembled to our precise specifications. Before assembly each block is checked for correct dimensions, cylinder bore, main alignment, block flatness, and more to ensure you get the best foundation for your new engine. Every engine we assemble has an archived spec sheet where tolerances, torque specs, and clearances are documented as part of our standard quality control process.

PRODUCT NOTES

  • Horsepower and torque numbers, and RPM limits are approximate and can vary significantly depending on numerous factors such as your turbocharger selection, intake and exhaust restriction/backpressure, and fuel octane and quality, among many others. The advertised numbers herein are based on optimal conditions and utilizing proper supporting modifications, but are generally attainable results by an average customer. Your results may vary.
  • In rare cases, our component selection may vary from advertised based on supply chain delays. All component substitutions will be communicated in advance by your AMS Sales Representative during the engine assembly process.
  • Assumes that a good condition core long block is sent in to build from. To avoid confusion and the possibility of missing parts we ask that all long blocks are shipped to us fully assembled from valve covers to oil pan, including timing covers. Components that are not in reusable condition will have replacements quoted during the engine assembly process.
  • Photos are for illustrative purposes only and are not indicative of the exact components included in each variation of an AMS Engine Assembly.
