Mini Engine Remapping, Tuning - Avon Tuning

BMW Remapping Service

There’s a lot to love about modern Minis. Their go-kart handling, sporty styling and throaty little engines belie their surprisingly practical nature, and the JCW variants offer an incredibly engaging drive that’s basically unmatched by competing hatchbacks.

In fact, driving a modern mini on windy backroads is probably some of the best fun you can have on four wheels. But no car is perfect, and we think most Minis are hugely improved by an ECU remap.

Like the BMWs built by their parent company, Clubmans, Convertibles and the vaunted JCW 3-Door Hatch all roll out of the shop with engine management software that’s actually designed to throttle your car’s performance: Reducing its power and torque, making your throttle slightly less responsive or introducing unnecessary flat-spots in an attempt to ‘normalise’ your vehicle’s performance.


There’s a very good reason for this (seemingly underhand) practice – Mini need their cars to perform in a range of different environments, using fuel of varying quality and wildly divergent servicing regimes.


They need to make sure that their cars perform in every market serviced by BMW, and that means erring on the side of caution when it comes to things like mapping torque curves or defining a specific model variant’s power band.

But if you’re driving your Mini in a temperate Western climate, using high-quality fuel and servicing your car at regular intervals, these limitations are wholly unnecessary. They also create a significantly less engaging experience and mute a lot of your car’s raw potential which is why we offer a bespoke Mini remapping service.

Will My Mini Benefit From A Remap?

To ensure that their cars work equally-well in every region serviced by BMW, Mini often artificially detune their vehicles before they roll out of the factory.

For people who intend to drive Minis in temperate environments, and take good care of their vehicle by servicing them regularly and using high-quality fuel, this process is wholly unnecessary and significantly decreases your car’s potential.

Fortunately, it is possible to restore your Mini’s artificially-restricted performance with an ECU remap. This is where we plug into your car’s diagnostic port and fine-tune the software that manages your engine. In simple terms, it’s about rewriting the spreadsheets that your Mini’s ‘brain’ (or electronic control unit) uses to determine things like your optimum air/fuel ratios, ignition timing or throttle response.

This enables us to squeeze more power and torque out of your engine – eliminate some of those pesky flat spots and make your Mini feel much more responsive to drive.

But it’s a careful and exacting process. To increase performance without pushing your engine too hard or compromising the reliability of your vehicle, our technicians have to hand-write a remap for each model variant and engine combo in Mini’s past and present lineup.

That means writing custom code for everything from the mid-range Mini Cooper R50 with a 1.6l supercharged petrol engine, right through to the Clubman.

Our remaps are designed to account for the peculiarities of your car; eking out increased performance in a way that’s sympathetic to the limitations of your hardware. We also test every remap on a state-of-the-art Dimsport rolling road to ensure that they’re delivering the performance increases we expect, without placing too much strain on delicate parts.

We’ve been remapping Minis for the past 10 years, and we’re so confident in the quality of our Mini remaps that we offer a full lifetime warranty against software faults.

We also store your Mini’s original remap on our servers as part of the ECU flashing process so if you ever decide that you want to roll your car back to its default settings, we’ll be able to restore your factory map in a matter of minutes.

What Can I Expect From A Mini Remap?

The obvious answer is increased power and torque; giving your Mini a sportier feel and completely transforming your driving experience. But it’s the other, less obvious benefits that really make a difference to the way your car feels.

An Avon Tuning remap will also tweak your torque curves; smoothing out any flat spots and normalising power delivery so that your acceleration feels smoother, more refined and polished.

Irrespective of whether you’re driving a Clubman, a Roadster or a Cooper F56, our remaps will also improve throttle response and unlock more power at the bottom of your RPM range; increasing drivability at low speeds and/or around town.
