What we do

We’re a specialist electronic and tuning workshop. Our focus areas are below — no generic servicing, just expert work on the systems that matter.

Diagnostics

Deep fault-finding with OEM-level tools, live data, guided tests and smoke/pressure rigs.

Key Programming

Add/reprogram keys, immobiliser adaptation, lost-key solutions (ID48/ID46 and more).

ECU Coding & Programming

Module coding, firmware updates, virginising & cloning for ECU/BCM/TCU and others.

Specialist service

ECU Remapping — safe, reversible performance

Engine remapping optimises factory parameters to unlock smoother power and torque. We carry out health checks before any tune, keep your original file, and provide clear before/after diagnostics.

  • Stage 1 maps for petrol & diesel
  • DPF/EGR-friendly options and smoke-free calibrations
  • OBD-based flashing with battery support and full backups
  • Dyno-validated maps available via partner network

Electronic fault-finding

Diagnostics — find the fault, fix it first time

We use OEM-level diagnostics suites, oscilloscope testing and guided fault paths to pinpoint issues across engine, ABS, airbag, ADAS and infotainment systems.

  • Full scan, live data & freeze frames
  • Injector & sensor testing, smoke/boost leak checks
  • Wiring/connector integrity and CAN bus analysis

Immobiliser solutions

Key Programming — add, replace or recover

Lost all keys or need a spare? We program transponders and remotes, adapt immobilisers and handle many late-model crypto IDs.

  • Spare & replacement keys (remote/fob)
  • All-keys-lost recovery on supported models
  • IMMO data read/write, EEPROM/MCU where required
Book key programming Supported models

ECU Coding, Programming & Cloning

We code and program replacement modules and can clone ECUs where repair or replacement demands a data transfer.

  • ECU/TCU/BCM coding & variant configuration
  • Software updates & online programming where supported
  • EEPROM/flash read-write for cloning & virginising

FAQs

Is engine remapping safe?

Yes, when performed on a healthy vehicle using conservative, vehicle-specific calibrations. We carry out pre-checks and retain your original file so we can revert at any time.

What does a diagnostic session include?

In just one hour, we start with a full scan and live data review, followed by targeted tests (smoke/pressure, oscilloscope, wiring integrity) to confirm the root cause.

Can you program keys if all have been lost?

We cannot program lost keys, but we can add spare keys — a cost-effective way to avoid being left without any. For many models, this is supported. We’ll confirm by VIN/model and recommend the most economical solution.

What’s the difference between coding, programming and cloning?

Coding configures a module to match your vehicle's options; programming updates or writes software; cloning transfers immobiliser and calibration data from one unit to another.
