Mobile Car & Van ECU Remapping & Diagnostics Across the East Midlands
Whether you're after more performance, better economy, or need a fault properly diagnosed, every job starts with a full health check before any file is touched. Each service below has its own page with full detail, pricing and how it works. Some appointments may require a booking deposit, confirmed before you book.
Tell me what you drive
Start with a quick message or leave your name and number. I will follow up for the vehicle details and confirm suitability and price before you book.
This does not take payment or make a booking. Final suitability depends on the exact ECU, programming method, vehicle condition and diagnostic results.
Brands I Remap
A sample of the makes I work on regularly, if yours isn't listed, get in touch and I'll check compatibility.
Currently specialising in cars and vans. Ask about your specific make and model and I'll check compatibility.
Key terms explained
Not sure what any of this means? Here's the short version.
ECU
- The engine's onboard computer, which controls how it runs, power, fuel use, emissions and more.
Remap
- Rewriting the software on your ECU to change how the engine behaves, for more power, better economy, or both.
EGR
- Exhaust Gas Recirculation valve. A common failure point on diesels that can cause warning lights and rough running.
DPF
- Diesel Particulate Filter. Traps soot from the exhaust, can block over time, especially on cars used for short journeys.
AdBlue / SCR
- A fluid injected into the exhaust on some diesels to cut emissions. Faults here can stop a car from starting.
DTC / Fault Code
- A code stored by the ECU when it detects a problem, what triggers your dashboard warning lights.

Suitability, results and legal use
All tuning is subject to a satisfactory diagnostic health check. Quoted power, torque or economy changes are estimates rather than guarantees and can vary with fuel quality, maintenance, modifications, mileage and mechanical condition.
Customers are responsible for notifying their insurer of any vehicle modification. A remap may affect manufacturer or third-party warranty cover.
Road-going vehicles: Myst Auto does not offer or quote DPF, GPF, catalytic-converter, EGR, AdBlue/SCR or other emissions-control deletion, bypass or deactivation for a vehicle that is, or may later be, used on a public road. I can offer diagnostics, DPF cleaning and regeneration where suitable, fault-code investigation and guidance towards a compliant repair.
Removing, disabling or obviously modifying manufacturer-fitted emissions equipment can make a vehicle unlawful to use on the road, result in an MOT major defect and affect insurance. Passing an emissions test does not by itself prove that a modified vehicle is lawful.
Competition, export and permanently non-road vehicles: Controlled-use EGR, DPF and AdBlue/SCR software enquiries are shown on the relevant service pages. I will not provide a quote, accept payment or agree work unless the vehicle's qualifying purpose, ownership, location and transport arrangements have first been reviewed in writing. A dedicated competition vehicle must be transported without using public roads; export enquiries require supporting evidence. SORN status or an “off-road use only” declaration does not by itself establish eligibility.
A customer's declaration is evidence only; it does not make an otherwise unlawful modification legal or transfer away Myst Auto's own responsibilities.
Customers must provide accurate information, be authorised to approve the work and notify their insurer or relevant authority where required. Myst Auto may refuse any work where the intended use or legal position is unclear.
