Automotive Electronics & Software.

We are passionate about every aspect of electronics and software in automotive vehicles — market-leading DPF/FAP solutions, custom ECU remapping through the OBD socket, our own tuning boxes and emulators, and diagnostics using dealer-level equipment.

01 The specialism

Most garages read the fault code. We read the software.

Chip tuning once meant lifting an EPROM out of an engine control unit. Today we modify almost everything through the diagnostic port — no opening the computer, no cutting into the car.

Every map we write is custom. We health-check the vehicle first, listen to what you actually want from it, then build the file and road-test it with you — on the roads it will be used on.

Over ten years of that has made us the workshop other people send the difficult cars to: tuning-protected ECUs, particulate filters, crash data, keys and immobilisers.

03 Remapping

The power your engine already had.

Manufacturers leave margin for poor fuel, severe weather and neglected servicing — then limit power again to separate one trim level from another. In the UK, with good fuel and sensible servicing, most of that margin is simply unused.

On a turbocharged engine it feels like a different car — a bigger one. On diesels it usually comes with reduced fuel consumption too, though that mostly depends on your right foot.

Read through the OBD port

In most cases the software is modified through the diagnostic socket, with no need to remove or open the ECU.

Scanned again afterwards

After every DPF or custom remap job we run a full diagnostic scan to confirm the vehicle is fully working with no faults or codes present.

Files handled properly

Trade customers send and receive work through our ECU file portal rather than over email. Open the portal ↗

05 Tuning boxes · PowerBox range

Extra power, ten minutes after the box arrives.

Plug-and-play devices for the modern turbo diesels — up to 30% extra power in a convenient, safe form. Supplied complete with OEM cables and fitting instructions, pre-set with the optimal programme for your engine, and transferable to another car with the same engine.

06 Diagnostics

If we can’t tell you what’s actually wrong, you don’t pay.

A flashing light on the dashboard can have several different meanings and several different sources. Every time it’s misread, someone pays for a part that was working perfectly well.

So we don’t use universal diagnostic devices. Only state-of-the-art dealer-level equipment, and as much time and testing as it takes to establish what the problem genuinely is.

Diagnosing, to us, means telling you what is wrong and specifically what needs replacing or fixing to repair it. That approach costs us more. It costs you less.
