What is an
ECU?

The Engine Control Unit (ECU) is the brain of your vehicle. It governs fuel injection, ignition timing, emissions controls, and dozens of other critical parameters — processing thousands of data points per second to keep your engine running safely and efficiently.

When an ECU fails or develops faults, the impact ranges from poor fuel economy and reduced power, to a complete no-start condition. We identify the root cause and fix it — not just clear the codes.

What We Do

SVC_01
ECU Diagnostics
& Testing

Full bench testing of your ECU against manufacturer specifications. We identify faults at the component level — not just fault codes.

  • Live bench simulation testing
  • Component-level fault isolation
  • Detailed written diagnostic report
  • Pre-repair health assessment
  • No-fault-found testing available
SVC_02
ECU Repair
& Rebuild

Hands-on hardware repair of failed ECUs. From blown capacitors and corroded connectors to failed processor circuits — we fix the unit, not the symptom.

  • BGA & SMD component rework
  • Corrosion & water damage repair
  • Power stage & driver repair
  • EEPROM / flash data recovery
  • 12-month repair warranty
SVC_03
ECU Remapping
& Tuning

Precision recalibration of ECU maps to unlock performance, improve economy, or adapt to hardware changes. Custom dyno-validated or bench-written.

  • Stage 1 / Stage 2 performance maps
  • Economy & emissions optimisation
  • DPF / EGR / AdBlue solutions
  • Speed limiter & rev limiter adjustment
  • Custom map writing on request

The Process

01
Send Your ECU

Remove and package your ECU securely. Ship it to us using any tracked courier service. We'll confirm receipt and log it within 2 hours.

02
Bench Diagnosis

We connect your unit to our test bench, simulate live vehicle conditions, and perform a full fault analysis at the hardware and software level.

03
Quote & Approval

You receive a detailed diagnostic report and fixed-price quote. No work proceeds without your explicit approval. No hidden charges.

04
Return & Fit

Repaired and tested unit is returned via tracked courier — usually within 48 hours of approval. Plug back in and drive away.

Precision.
Not Guesswork.

We're engineers, not parts-swappers. Every unit we work on receives a documented diagnosis before any work begins.

Hardware-Level Repair
We replace faulty components on the PCB itself — not the whole unit. This saves cost and preserves your vehicle's original calibration data.
🔬
Bench Test Environment
Every ECU is verified on our bench before return — simulating real engine conditions to confirm the repair holds under load.
🔒
Data Backed Up First
We read and archive your ECU's flash data before touching anything. Your VIN coding, immobiliser pairing, and maps are safe.
📋
Full Written Report
You receive a plain-English diagnosis — what failed, why, and what was done to fix it. Useful for insurance or resale records.
