Ecumaster Digital ECU Tuner 3 DET3 NA / 4 Bar Piggyback Controller

Ecumaster Digital ECU Tuner 3 DET3 – NA or 4 Bar Piggyback Controller

The Ecumaster Digital ECU Tuner 3, commonly known as the DET3, is one of the most popular piggyback tuning devices on the market. Compact, versatile, and cost-effective, it is a popular choice for customers looking to gain more control over fuelling, ignition, boost, and auxiliary functions without moving to a full standalone ECU.

This listing is available in DET3 NA and DET3 4 Bar versions, allowing you to choose the correct unit for your application.

The DET3 is suitable for a wide range of petrol and common rail diesel applications and is especially useful for modified engines where additional tuning flexibility is required. For many applications, the DET3 allows removal of the airflow meter, supports injector control, and provides ignition timing adjustment through configurable 16×16 tables.

Available Options

DET3 NA
Suitable for naturally aspirated applications or installations where an external/load input setup is being used as required by the tuner.

DET3 4 Bar
Supplied with an integrated 4 Bar MAP sensor, making it suitable for boosted applications requiring a wider pressure measurement range.

Key Features

Popular Piggyback Tuning Unit
A compact and capable piggyback ECU controller used across a wide range of tuning applications.

NA or 4 Bar Version Available
Choose between the DET3 NA version or the DET3 4 Bar version depending on your engine setup and tuning requirements.

Fuel Implant Mode
In Fuel Implant mode, the DET3 can operate more like a standalone ECU, calculating fuel requirements using inputs such as RPM, IAT, CLT, TPS, and O2 feedback.

Airflow Meter Delete Capability
For many applications, the DET3 allows the original airflow meter to be removed when correctly wired and calibrated.

Injector Control
Can drive up to 4 injectors in batch-fire operation.

Ignition Timing Control
Ignition timing can be adjusted using configurable 16×16 tables.

Configurable Parametric Outputs
Output channels can be configured for functions such as boost control, nitrous activation, water injection, methanol injection, and other auxiliary controls.

Advanced Motorsport Functions
Supports features such as launch control and map switching.

Petrol & Common Rail Diesel Support
Suitable for use on petrol engines and common rail diesel applications where correctly installed and configured.

Windows Tuning Software
Client software is compatible with Windows XP, Vista, 7, 8, and 10.

Operating Modes & Functionality

The Ecumaster DET3 is designed to be flexible and can be used in different ways depending on the installation.

It can be used as a traditional piggyback controller to modify signals and provide additional tuning control, or in Fuel Implant mode where it calculates fuelling based on engine operating conditions.

Depending on the vehicle and setup, the DET3 can be used for:

• Airflow meter removal
• Additional fuelling control
• Injector control
• Ignition timing adjustment
• Boost control using a boost control solenoid
• Nitrous activation
• Water or methanol injection control
• Launch control
• Map switching
• Petrol and common rail diesel tuning applications
