Performance services built around real projects.
From standalone ECU tuning and MaxxECU installation to bespoke wiring, CAD design, vapour blasting and workshop support, we help bring builds across the finish line.
Support for serious road, track and motorsport builds.
A strong build is rarely about one single part. ECU choice, wiring quality, sensor data, mechanical condition, fabrication, calibration and aftercare all affect how well the finished car performs.
Our services are designed to work together. We can help with one focused job, such as a wiring harness or ECU calibration, or support a more complete project from planning through to setup, tuning and refinement.
Choose the support your build needs.
Whether you are upgrading a classic to EFI, building a track car, solving wiring problems or planning a full standalone ECU setup, we can help you choose the right route.
Standalone ECU Tuning
ECU supply, installation, setup and calibration, with a strong focus on MaxxECU. We configure the system properly, check the data and tune the car for safe power delivery, drivability and protection.

Custom Wiring Harnesses
Bespoke automotive, clubsport and motorsport wiring harnesses built around the car, ECU, sensors and future serviceability.
See How We Build
CAD & 3D Design
Custom brackets, sensor mounts, housings, enclosures and one-off parts designed to fit properly and solve real problems. Useful for prototypes, conversions and small-batch production.

In-house Vapour Blasting
Vapour blasting for aluminium and metal components, ideal for restoration, rebuild preparation and giving tired parts a clean, uniform finish without an aggressive look.

Diagnostics & Support
Fault finding, datalog review, setup checks, remote login support and trackside support by arrangement. Useful when a car needs proper diagnosis rather than guesswork.
Ask About SupportStandalone ECU products, installation and calibration in one place.
ASD Tuning supplies and supports MaxxECU in the UK. We can help you choose the correct ECU, plan the wiring, configure the system, calibrate the car and support it after the initial setup.
ECU Supply
Advice on MaxxECU Mini, Street, Race, Sport and Pro options for your build.
Installation
Standalone ECU fitting, sensor setup, wiring integration and configuration.
Calibration
Dyno tuning, drivability, boost control, cold start and protection strategies.
Aftercare
Datalog review, refinement, remote support and troubleshooting where suitable.
A clear process from first message to finished setup.
We prefer to understand the car properly before recommending parts or booking work. That helps avoid wasted time, mismatched components and avoidable problems later in the build.
Discuss the Build
We start with the vehicle, engine, ECU, parts fitted, goals and how the car will be used.
Plan the Route
We advise on the sensible next step, whether that is wiring, ECU setup, mechanical work or calibration.
Carry Out the Work
The work is completed with attention to reliability, serviceability and the details that matter long-term.
Validate & Support
We check the setup, review data where needed and provide ongoing support where suitable.

James
Recently purchased an ECU, had a custom engine harness made and had my car tuned by Jake at ASD Tuning. Very helpful and friendly — definitely recommend for high quality work.
Michael
ASD Tuning advised us on a new ECU system for our competition car. Jake’s professional advice and service stood out. We solved a long-standing misfire, recovered lost power and completed our first competitive event.
Jonathan
I needed a custom part for a JCW R53 airbox. After sending a 3D scan and measurements, Jake produced exactly what I needed — perfect fit and factory look.
Harvey
Months of chasing electrical gremlins — Jake found the fault quickly and fixed it in days. Hats off to you.
Sean
Jake has often gone above and beyond. Diagnosed faults from previous work and helped improve both performance and reliability.
Rakesh
ASD Tuning have supplied MaxxECUs for all my cars, including full install with wiring and mapping services. Definitely will be using again for my next project.
