Due to current events regarding the Covid-19 situation.

We are a family run business and need to protect the health and safety of our family members, and of course our loyal customers.

We have taken the decision to close at the end of business today 24 th March 2020 until further notice.

We will not be losing any staff members through this and plan to do our bit in isolation to help the country recover as quickly as possible.

Hopefully business will get back to normal fairly quickly along with life as we know it. Thank you all for your continued support at this difficult time, please keep safe.

Best Wishes,

Phil Davies, Kev, Nath & Tom Ellis

What is Vehicle Remapping and How is it Done?

What is vehicle re-mapping?

ECU remapping is the modern version of Engine tuning, but without costly engine modifications.

ECU ReMapping” sounds much more complicated than it really is and despite the technology being extremely advanced the principal is actually incredibly simple and straightforward.

Basically, since 1999, all vehicle’s built, have been controlled by an onboard computer. This is known as the Engine Control Unit (ECU). The ECU controls a host of different engine functions including ignition timing, fueling and boost pressure.

Each vehicles ECU contains the manufacturers settings that have been re-set and fixed to manage with sub-standard fuels found in some countries, allow for build tolerances into their engines and to comply with emission targets, operate in areas with extreme environments and allow for some owners irregular service standards and intervals.

Black Flash

Our market leading Black Flash tuning module is fast, safe, reliable and most importantly it provides a risk free connection to the ECU that is able to communicate directly through the OBD support without any need for any kind of physical interference.

How is it done?

  1. The technician downloads a copy of the unique existing file on your vehicle ECU, through the vehicles OBD diagnostic socket.
  2. This file is then immediately uploaded to the BLACK CODE head office, where a personalised upgrade is developed for your individual vehicle and specification.
  3. Within about an hour, the re-mapped file is sent back to our technician and uploaded back onto your vehicles ECU.

It really is that simple. There is no visible modification is made to the vehicle and you will feel the immediate benefit.

So, whether you are re-mapping your vehicle to save thousands of pounds in increased fuel efficiency or whether you simply want a more responsive and powerful vehicle, or both!

We at PLYMOUTH ECU REMAPPING can simply and quickly optimise the settings to make this a reality.

Questions & Answers

Can a re-map be detected by a dealer servicing the vehicle?

The dealer cannot determine that the ECU has been modified with their equipment, as our software is designed to be non-detectable. Should the dealer accidentally overwrite our upgrade we will happily provide another software upgrade completely FREE of charge.

In some circumstances a car dealership may re-flash the ECU on a vehicle to upload the latest software. If this happens then our modified file is overwritten. So all you have to do is call us and we will reinstall your optimized map completely FREE.

How long will it take?

Re-Maps usually take about two hours from start to finish, however, we endeavour to be as flexible as possible to fit in with your availability and can often find alternative options that can reduce this time further where necessary.

Is re-mapping the same as chipping?

Chipping is an older version of what re-mapping is today, which involved the ECU being physically opened and replacing the main microchip with a modified microchip. Our far more advanced methods mean that there is now no need to open the ECU, risking potential damage and failure.

Do Black Code use generic files?

Unlike many competitors Black Code Maps are custom written in-house in the UK, with information taken from your individual vehicle and can be designed at your request to provide more power, better economy or a perfect blend of both. We NEVER use generic, third party or off the shelf maps.

Will a Black Code Re-map shorten an engines life expectancy?

The simple answer is no; Black Code optimise the parameters within the ECU without exceeding the limits of the vehicles engine.

Can the original settings be re-installed

Black Code always backs up the original file on to our off site secure server so that the original file can be loaded back onto the vehicle at any time.

What risks are involved with re-mapping a vehicle

We are, modesty aside, nationally recognised as the UK’s leading authority on vehicle tuning and ECU Re-mapping. All upgrades are undertaken by fully trained Black Code factory technicians ensuring the safest, most reliable and efficient upgrades.

ECU re-mapping or a tuning box.

Engine tuning boxes generally only increase the fuel pressure and injection periods. This leads to an uneven spread of power and spikes, due to poor quality signal processing. These problems do not exist with ECU re-mapping, because all the parameters of the engine management are adjusted in unison, including torque and turbo limiters which can not be accessed by a tuning box.
