What Is the AMP Competition ECU?
The AMP Competition ECU is a programmable standalone ECU designed to control fuel, ignition, and auxiliary systems for high-performance engines. It supports up to 8-cylinder sequential fuel and ignition (or up to 4-rotor rotary with sequential fuel and individual leading/trailing ignition outputs), making it a flexible foundation for modern builds.

8×8 Sequential Fuel & Spark
If you’re building a serious engine, sequential control is the difference between “it runs” and “it’s dialed.” AMP Competition supports up to 8 sequential high-impedance injectors and up to 8 logic-level spark outputs for precise per-cylinder timing and consistent control across the RPM range.
- Sequential fuel injection for refined fueling and trims
- Logic-level ignition outputs with broad ignition compatibility
- Supports 50+ ignition modes (including common OEM patterns)
Integrated Bosch LSU 4.9 Wideband Control
AMP Competition includes integrated Bosch LSU 4.9 wideband control, simplifying wiring and reducing the need for an external wideband controller. This keeps AFR feedback tightly integrated into your tuning workflow—especially valuable for boosted and high-load calibration work.
Stepper Idle Support (IAC)
For street/strip and race cars that still need stable idle control, AMP Competition supports Stepper IAC for reliable idle behavior across temperature changes, loads, and transient conditions.
Motorsports I/O (Analog + Digital + Speed) and Flexible Outputs
A competition ECU isn’t just about fuel and spark—it’s about how many clean inputs you can bring in, and how many outputs you can control without adding extra boxes. AMP Competition provides a strong I/O package and allows unused injector outputs to be repurposed as programmable on/off or PWM outputs.
| Category | What You Get |
|---|---|
| Analog Inputs | 8 |
| Digital Inputs | 6 |
| Speed Inputs | 5 |
| Dedicated Inputs | MAP, Baro, PCB Temperature + LSU 4.9 wideband input |
| Injector Outputs | Up to 8 sequential high-impedance (unused can be repurposed) |
| Spark Outputs | Up to 8 logic-level outputs |
| Additional Outputs | 5 PWM outputs, Tach Out, Fuel Pump (on/off or PWM), Stepper IAC |
Dual SuperSeal Connectors (60 Pins Total)
AMP Competition uses dual SuperSeal automotive connectors with a total of 60 pins—secure, environmentally sealed connections suitable for harsh engine bay conditions and motorsports vibration.
Integrated Sensors: Onboard 4-Bar MAP + Barometric Pressure
To simplify installs and reduce external components, AMP Competition includes an onboard 4-bar MAP sensor and an onboard barometric pressure sensor. Fewer external boxes means fewer failure points and cleaner wiring.
Advanced Control Features Built for Competition Use
This ECU includes the core strategies tuners rely on for modern high-power builds—whether you’re building for drag racing, roll racing, road course, or a high-end street/track car.
- Boost control: open/closed-loop, boost by gear & speed, switchable high/low tables, single solenoid or dome control
- Traction control: multiple strategies including Perfect Run, RPM control, and VSS % slip
- Launch control: launch, trans brake, and bump box control
- Nitrous control: staged/progressive for wet or dry setups
- Rev limiting: three-step (burnout / launch / redline) plus line-lock and flat shift options
- Speed limiting: pit-speed and roll-race limiters
- Flex fuel: blending for fuel, spark, boost, and enrichment (compensates ethanol content + fuel temperature)
- Water/meth control: load + RPM-based injection with low-fluid safety detection
VVT Control (Up to 4 Camshafts)
AMP Competition supports VVT control for up to 4 camshafts with both open-loop and closed-loop strategies, giving you the tools to manage cam timing for drivability, spool, and power where it matters.
Tuning Modes + Self-Learning Fuel Strategy
AMP Competition supports multiple tuning approaches so you can match ECU strategy to your engine and intake configuration:
- VE-based tuning
- Speed Density
- Alpha‑N
- MAF
- ITB tuning modes
- Self-learning fuel strategy: real-time adaptive fuel tuning support
Safety and Engine Protection Strategies
High-power engines are expensive. The right ECU doesn’t just make power—it helps protect it. AMP Competition includes engine protection strategies tuners can configure to match the build and risk tolerance.
- Limp mode + fault indication: limp strategies and check engine lights for critical sensors
- Knock detection: dual DSP-based knock inputs with fine-tuning capability
- RPM limit vs temperature: reduces allowable RPM as temps rise
- Low oil pressure shutdown: user-set shut down threshold to prevent damage
- Fuel pressure compensation: adjusts for fuel pressure changes to keep performance stable
Onboard Data Logging & Diagnostics (No Extra Logger Required)
AMP Competition includes internal high-speed data logging so you can validate changes, diagnose issues, and improve consistency without adding separate logging hardware.
- Up to 64 channels at 330 Hz
- Internal SD card storage
- Real-time clock for timestamped logs
- Three onboard diagnostic LEDs
- Log retrieval via USB or serial connection
Connectivity and Expansion
Modern builds often require more than engine control. AMP Competition supports integration and expansion using:
- CAN bus: digital dashes, I/O expansion, transmission controllers
- Serial / RS232
- Firmware updates: no locked features or subscription requirements
