What we do

The electronics and the engine

Reading a fault code is the easy part. We find out why it is there and fix the cause, whether that means a coding change, a repaired module or a rebuilt engine.

  • Live data

    Diagnostics and auto-electrics

    Faults traced to the cause, intermittent electrical ones included.

  • Dealer-level

    Coding and programming

    Coding, programming and adaptations without a trip to the main dealer.

  • On the bench

    ECU and module repair

    Repaired or cloned, then programmed back into the car.

  • In the workshop

    Keys and immobilisers

    Keys programmed and immobiliser faults worked on here.

  • Standard or modified

    Remapping

    Remaps, and standalone ECUs for builds that outgrow the factory one.

  • Machined in-house

    Engine building

    Rebuilds, forged engines, turbo kits and custom exhausts.

  • Cars and vans

    Servicing and repairs

    Servicing, MOT repairs, tyres and mechanical work.

  • Track and race

    Motorsport preparation

    Setup, preparation and fabrication for competition use.

Diagnostics and electronics

The fault the scanner missed

Some faults never set a code, and some codes point at the wrong part. We trace the fault with live data, and when a module is to blame it comes out and goes on the bench: repaired, cloned or reprogrammed, then refitted, rather than replaced with a new unit at main-dealer prices.

Engines and performance

Machined, measured, built

AMD started with Mitsubishi Evos, where the engine, the electronics and the setup all have to agree. Every build is still done that way: machining in-house, standard rebuilds and forged engines, turbo kits, exhausts, and the remap to go with them.

Servicing and repairs

Everyday cars, same standard

It is not all performance work. We service and repair everyday cars and vans as well: MOT repairs, exhausts, electrics and tyres, with the same diagnostic kit and the same straight answers.

Took my car in for a full service and Suspension setup. … Honest when it comes to recommendations to maintain the car also. The car felt unbelievable on the drive back, cannot recommend highly enough.

Went around the block trying to get my car fixed also spending a small fortune with the issues never going away. AMD took my car in without waiting. Within 2 days my car was as good as new.
