Locked ECU? Already in the price. Every BMW in this generation was built after June 2020, so its ECU is locked. We unlock it on our own bench the same day, with no extra time, and the £100 is already included in the prices shown. On its own, if we’re not tuning the car, the unlock is £249. 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.

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.

Stage 2 Diesel supporting mods: DPF delete (off-road use only) + uprated intercooler.

Stage 2 Plug-in Hybrid supporting mods: ask us what your engine needs.

Stage 2 Petrol supporting mods: decat or sports cat + uprated intercooler.

Stage 2 Diesel supporting mods: DPF delete (off-road use only) + uprated intercooler.

Every price on this page is a full custom dyno tune

Not a generic file bought in and flashed over the port. Your BMW 5-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 5-Series remapping questions

How much power will a Stage 1 remap add to a BMW 5-Series?

Gains vary by engine. The strongest on the BMW 5-Series is the M550i (2020 on), which goes from 530bhp and 750Nm to 680bhp and 850Nm, a gain of 150bhp. Find your engine in the table above for its own numbers.

What does a BMW 5-Series remap cost?

Prices start at £449 inc VAT for Stage 1 on a BMW 5-Series. Each engine in the table shows its own price, and adding gearbox tuning at the same time saves £125. Bumper 0% finance over 6 months and Klarna are both available.

Will my BMW 5-Series need unlocking before it can be tuned?

BMW models built from roughly mid-2020 have an encrypted ECU that must be unlocked first. It is done here rather than sent away. Check your registration to see whether your particular car needs it. Check if your ECU is locked ›

Do I need any hardware for Stage 2 on a BMW 5-Series?

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.

Does a remap invalidate the warranty or insurance on a BMW 5-Series?

A remap is an aftermarket modification, so it is your responsibility to declare it to your insurer. It may also affect any remaining manufacturer warranty. Our maps are fully reversible: the car can be put back to its factory software whenever you need.

How long will my BMW 5-Series be with you, and can it be undone?

Most Stage 1 tunes take around two hours. If the ECU needs unlocking we do that here on our own bench during the same visit, so it does not make the appointment any longer. It is completely reversible: the car can go back to its factory software whenever you need.

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.
