Custom Remote Tuning Built Around YOUR VQ37VHR

If you have upgraded the intake, exhaust, test pipes, high-flow cats, headers, or other performance parts on your Nissan 370Z or Infiniti G37, your factory ECU calibration was never designed around those modifications.

And a generic tune made for somebody else's car isn't the answer either.

The Kugan Tuning EcuTek Remote Tune is a custom calibration built around:

• Your vehicle

• Your modifications

• Your fuel

• Your datalogs

• Your performance goals

We tune your VQ37VHR remotely, so you can get a professional calibration without bringing the car to our dyno.

What Will You Notice After the Tune?

A properly calibrated VQ37 isn't just about chasing a peak horsepower number.

The biggest difference is how the car feels throughout the entire RPM range.

Depending on your setup, you can expect improvements in:

• Throttle Response

• Mid-Range Torque

• High-RPM Power

• Acceleration

• Air/Fuel Calibration

• Ignition Timing

• Engine Response

• Overall Drivability

The goal is simple:

Make your 370Z or G37 feel stronger, sharper, smoother, and properly calibrated for the parts actually installed on the car.

This Is a CUSTOM Remote Tune — Not a Generic File

This is not a one-size-fits-all flash.

Your tune is built around your actual vehicle setup.

After we create your initial calibration, you will collect datalogs from the vehicle.

We review those logs and make the necessary changes to the tune.

You flash the revision.

You send another log.

We review it again.

We continue refining the calibration based on real data from your car.

That means we are not guessing.

We are looking at how your engine is actually responding and adjusting the calibration accordingly.

Typical VQ37 Performance Gains

Actual horsepower gains will vary depending on your modifications, fuel quality, vehicle condition, weather, dyno type, and other factors.

Typical naturally aspirated results may include:

But peak horsepower is only part of the story.

A properly tuned VQ37 can feel substantially better because the calibration is being optimized throughout the RPM range.

That means better response, stronger acceleration, and improved drivability instead of simply chasing one dyno number.

EcuTek RaceROM Features

One of the biggest advantages of tuning the 370Z and G37 with EcuTek is the additional control available through the factory ECU.

Depending on your vehicle, configuration, and requested setup, available features can include:

• Multiple Map Switching

• Launch Control

• Flat-Foot Shifting

• Custom Map Functions

• Valet / Reduced Power Maps

• Advanced Data Logging

• ECU Connect Integration

We will configure the appropriate available features for your vehicle and setup.

How the Remote Tuning Process Works

Step 1 — Purchase Your Tune

Place your order and select whether you already own the required EcuTek hardware or need to purchase it with your tune.

After your order is placed, we will gather the information needed to build your calibration.

We will need details such as:

• Year

• Model

• Transmission

• Engine

• Intake Setup

• Headers

• Test Pipes or Catalytic Converters

• Exhaust

• Fuel Type

• Additional Engine Modifications

Step 2 — We Build Your Initial Calibration

We use your vehicle information and modification list to prepare the initial calibration for your car.

This becomes the starting point for the remote tuning process.

Step 3 — Flash the Vehicle

Using your EcuTek hardware and a Windows laptop, you will flash the calibration into your factory ECU.

We will provide the instructions needed to get started.

Step 4 — Record a Datalog

You will follow our instructions and record the requested datalog.

The datalog allows us to see what is actually happening inside the engine while the vehicle is running.

Step 5 — We Review and Revise

We review the datalog and make the necessary calibration changes.

This can include adjustments to:

• Air/Fuel Ratio

• Ignition Timing

• Throttle Calibration

• Engine Response

• Fueling

• Knock Control

• Other Calibration Parameters

Your revised tune is then sent back to you.

Step 6 — Continue Until the Calibration Is Dialed In

You flash the revision and send the requested follow-up datalog.

We review the new data and continue refining the tune as necessary.

This process allows us to tune the vehicle based on how your actual engine is responding, instead of relying on a generic file.
