Where are we based?

We are completely mobile enabling us to carry out the process at a time and location convenient to you. We cover anywhere within a 20 mile radius of BS1 completely free but will travel further for a small additional cost. If we are doing a carbon clean we will required access to mains electricity.

How long will it take?

Standard OBD maps can usually be completed within an hour if ECU removal is required it can take up to 4 hours. We will however 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. For example the actual time we need to be connected to your vehicle can often be as little as 15 minutes, so we can come and read the information from your vehicle and return at a later date to write the remap on.

Will it void my warranty?

The simple answer to this question is yes, any vehicle modification is likely to void your warranty. However many vehicles can be remapped via the OBD port, with these vehicles it would be unlikely to ever cause you warranty issues. With vehicles that require ECU removal it would be a little easier to detect but still unlikely to cause issues with warranties. Remapping by us would however be done completely at your own risk in this regard.

Is Remapping the same as Chip Tuning or 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.

How effective is your remapping service?

If you don’t immediately see the savings, if you can’t instantly feel the extra power or aren’t completely satisfied in any way, we will refund your investment in full ! Bristol Remaps is an industry leader and our bullet-proof vehicle re-mapping is recognised throughout Europe for it’s reliability and safety.

Do BR Tuning use generic files?

Unlike many competitors all Bristol Remaps files 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 remap from BR Tuning and Diagnostics shorten an engine life expectancy?

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

Can the original settings be re-installed?

Bristol Remaps 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 when remapping 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 BR Tuning and Diagnostics technicians ensuring the safest, most reliable and efficient upgrades.

ECU remapping 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.

Can a Remap be deleted by a dealer when servicing a vehicle?

The dealer may determine that the ECU has been modified however this is not straight forward 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 our modified file is overwritten. So all you do is call our local technician and they will re-install your optimized map completely FREE of charge.

*A small administration charge may be applied in certain circumstances.
