BR Tuning & Diagnostics

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.

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.

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. However, any deciding to have your vehicle remapped whilst under warranty will be done completely at your own risk in this regard.

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.

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.

Unlike many competitors, all BR Tuning & Diagnostics 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.

The simple answer is no; BR Tuning & Diagnostics optimises the parameters within the ECU without exceeding the limits of the vehicle's engine.

BR Tuning and Diagnostics always back 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.

All upgrades are undertaken by fully trained technicians ensuring the safest, most reliable and efficient upgrades

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.
