Locked ECU? No problem. BMW and Alpina cars built from June 2020 have an encrypted ECU. We unlock it on our own bench the same day — £100 added to a tuning booking — and it adds no time to your appointment. On its own, if we’re not tuning the car, it’s £249. Check your reg → · More on unlocking → Built from June 2026? Those cars use a new ECU lock that can’t yet be opened, so we can’t tune them for now. Email sales@dcremappinguk.com with your reg and we’ll let you know as soon as that changes.

Every price on this page is a full custom dyno tune

Not a generic file bought in and flashed over the port. Your BMW 6-Series is strapped to our in-house 4WD dyno and the map is written for your car, on the day, from its own data.

Health check firstWe look the car over and read the fault memory before we touch anything. If something is wrong, you get told. We don't map over a problem.
Live data loggingBoost, timing, fuelling and temperatures all watched in real time under load: knock on the petrols, rail pressure and exhaust temps on the diesels.
Custom calibration on the dynoThe map is built and adjusted run by run against what your engine is actually doing, not what a file supplier assumed.
Before and after printoutYou leave with the graph: your standard figures and your tuned figures, measured on the same rollers, the same day.

Spread the cost. From £74.83/mo over 6 months at 0% APR with Bumper, interest free.

BMW 6-Series remapping questions

What does Stage 1 tuning do for a BMW 6-Series?

Every BMW 6-Series engine is different, which is why they are listed separately above. At the top end the 640d picks up 80bhp, going 320bhp to 400bhp with torque up to 800Nm.

How much is Stage 1 tuning on a BMW 6-Series?

A BMW 6-Series Stage 1 is from £449 inc VAT; gearbox software is £325–£385 on its own, or £125 less when booked with the engine tune. Finance is 0% over 6 months with Bumper, or choose Pay in full when you book and pay with Klarna.

Is the ECU locked on a BMW 6-Series?

Only the later cars. From about June 2020 the factory locks the ECU, so it needs unlocking before tuning, which we handle in-house. Pop your registration in and it will tell you either way. Check if your ECU is locked ›

What supporting mods does a BMW 6-Series need for Stage 2?

It depends on fuel. Diesels need a DPF delete (off-road use only) and an uprated intercooler; petrols need a decat or sports cat downpipe plus an uprated intercooler. Stage 2 cannot be mapped safely on a standard car, so if yours has no supporting hardware we will fit Stage 1 instead.

What happens to my warranty and insurance if I tune my BMW 6-Series?

You will need to tell your insurer, as with any modification, and it can affect a remaining manufacturer warranty. Every map is reversible, so the BMW 6-Series can be put back to its factory software at any point.

Can the remap be reversed, and how long does it take?

Allow roughly two hours for Stage 1. A locked ECU is unlocked in-house on the same visit without a longer appointment. Everything is reversible: the BMW 6-Series can go back to its factory software on request.

Whichever you pick, the total carries through to checkout, so pay in full by card, Apple Pay or Klarna, or secure the slot with a £50 deposit. Figures are typical for a healthy, standard vehicle; your before and after dyno printout shows exactly what your car makes. Your car’s actual output depends on its condition, fuel quality and any supporting modifications. Prices shown are for Stage 1 custom dyno tuning inc VAT; locked ECUs (most BMW and Audi registered from mid-2020) carry an additional unlocking charge, confirmed when you book.
