True Plug-and-Play Installation (What Sets It Apart)

Many standalone ECUs require harness replacement, patch looms, or wiring changes. The AMP BMW E30 Plug-and-Play ECU is engineered differently — as a factory-connector standalone ECU built specifically for BMW E30 platforms.

What “True Plug-and-Play” Means

• Unplug the factory BMW E30 ECU

• Plug in the AMP ECU using the factory connectors

• Retain the original engine wiring harness

• No adapter harnesses

• No repinning

• No cutting or splicing

You get full standalone control without turning your E30 into a wiring project.

Factory Harness and Connectors — With Standalone Control

The AMP BMW E30 Plug-and-Play ECU is designed around what E30 owners value most: modern control without unnecessary wiring changes.

• Retains factory wiring layout

• Uses original BMW ECU connectors

• Supports advanced tuning strategies

• Preloaded base configuration for startup

• Full tuning and datalogging via TunerStudio

You get the benefits of a modern standalone ECU while keeping the simplicity and serviceability of the factory wiring.

---

Sequential Fuel and Ignition Capability

The factory BMW E30 ECU operates using batch fuel and batch ignition, which limits precision as engine demands increase.

This Plug-and-Play ECU allows E30 builders to run:

• Fully sequential fuel injection

• Fully sequential ignition control

Sequential operation improves fuel delivery accuracy, ignition timing control, throttle response, and overall engine efficiency — especially important for high-RPM, boosted, or competition-driven engines.

---

Camshaft Position Sensor Support

To enable sequential ignition operation, this ECU supports the use of a camshaft position signal.

AMP offers a BMW E30 Camshaft Sensor Kit designed specifically for E30 applications, providing a clean, vehicle-specific solution for adding cam position input without custom fabrication.

---

Designed to Grow With Your Build

As your BMW E30 evolves, the ECU is designed to grow with it.

Through its expansion capability, the platform can support upgrades such as:

• Coil-on-Plug (COP) ignition conversions
• Additional engine and pressure sensors

• Electronic boost control

• Advanced engine protection strategies

• Track-focused data logging and analysis

• Sequential Fuel conversions
  

This future-proof design allows you to expand beyond a factory-style configuration without replacing the ECU.
