Standalone Engine Management Without Rewiring
Subaru performance builds demand engine management that can support serious boost and power without turning the car into a wiring project.
AMP Engine Management offers vehicle-specific Subaru Plug-and-Play (PNP) ECUs that replace the factory computer and connect directly to the original Subaru ECU connector and factory wiring harness — no cutting, splicing, repinning, or adapter harnesses required.
From turbocharged EJ platforms to high-power race builds, AMP delivers true standalone control while keeping installations clean, OEM-style, and serviceable.
✅ True plug-and-play factory ECU replacement
✅ Uses the stock Subaru harness and factory connectors
✅ Built for high-boost Subaru performance and racing applications
✅ Supports drag racing and track use
✅ Made in the USA + real in-house tech support (20 years)
True Plug-and-Play Subaru ECU Design (What Sets AMP Apart)
Many standalone ECUs advertise “plug-and-play” but still require wiring changes, patch harnesses, or sensor conversions. AMP Subaru Plug-and-Play ECUs are engineered differently.
What “True Plug-and-Play” Means for Subaru Platforms
Unplug the factory Subaru ECU
Plug in the AMP ECU using the factory connector
Retain the original engine wiring harness
Retain factory sensors (where applicable)
No adapter harnesses
No repinning
No cutting or splicing
You get full standalone control without compromising the factory wiring layout.
Built for High-Boost Subaru Performance Builds
Subaru turbo engines are pushed hard — and the ECU has to keep up.
AMP Subaru Plug-and-Play ECUs are designed to support real-world high-performance turbo builds, including:
Built EJ engines
Upgraded turbochargers and intercooler systems
Fuel system and injector upgrades
High boost pressure applications
Race-oriented engine combinations
Custom Subaru turbo projects
Whether the goal is consistent track performance or competition-level power, AMP provides the tuning control required for serious Subaru builds.
Drag Racing & Power Control Features for Subaru Platforms
High-power Subaru builds require precise power management, and AMP ECUs are designed with those demands in mind.
AMP Subaru Plug-and-Play ECUs support advanced control strategies including:
Launch control for consistent, repeatable starts
Two-step rev limiting for staging and boost building
Boost control for turbocharged applications
Traction management strategies for high-torque AWD setups
Advanced engine protection strategies
These features help builders manage power delivery, improve consistency, and protect expensive Subaru engines — all while retaining a factory-harness installation.
Designed for Tuners and DIY Builders
AMP Subaru ECUs are used by:
DIY builders managing their own calibrations
Subaru performance shops
Remote tuners working with high-boost Subaru platforms
The hardware does not dictate how tuning is performed. It provides the professional-grade foundation tuners expect when working on serious Subaru performance builds.
Full tuning and datalogging are supported through TunerStudio.
Factory Harness and Sensors — With Standalone Control
AMP Subaru Plug-and-Play ECUs are designed around what Subaru owners value most: modern control without unnecessary changes.
Retains factory wiring layout
Uses original Subaru ECU connectors
Works with factory sensors (platform-dependent)
Preloaded base configurations for startup
Full tuning and datalogging support
You get the power of a standalone ECU without sacrificing serviceability or clean installation.
Designed to Grow With Your Build
As Subaru builds evolve, AMP ECUs are designed to grow with them.
Through expansion capability, AMP platforms can support upgrades such as:
Sequential fuel and ignition strategies
Additional engine and pressure sensors
Electronic boost control
Dome pressure control
Water-methanol injection
Advanced engine protection strategies
This future-proof design allows Subaru owners to push well beyond factory limitations without replacing the ECU.
