All manufacturers limit the power and torque of their vehicles for several reasons-

  • There are many different markets they face like differing fuel grades and quality around the world.
  • Different altitudes- vehicles that spend a majority of their life in the mountains where air pressure is lower.
  • In countries where emission laws a stricter.
  • To allow for drivers who don’t service the vehicles at the correct intervals and use low quality oils.
  • Issues with marketing and affordability.

It is likely that your vehicle is not achieving its full potential, both on power and on fuel efficiency. Many manufacturers offer several different power output levels of one engine, or an increased fuel efficiency model that are priced accordingly. This is mostly achieved by varying the mapping in the software.

Whilst the upgrade in many cases is undetectable, the responsible and correct answer to this question has to be "yes", your insurance company should be notified of any modifications including tuning. However, the good news is many insurance companies do not penalise you for upgrades of this nature, particularly if you're tuning for increased fuel economy.

No. A remap or any aftermarket work will not automatically invalidate a vehicles warranty. It’s a misconception that it will, and often those that know are not always clear about this fact. It’s very common for fleet users and companies to fit a speed limiter to their vehicles, others may want to fit a tow-bar or an upgraded sound system to their vehicle. These are common fitments, but they are after market changes just like a remap. A tow-bar does not invalidate your warranty so why should your remap?

However, manufactures of course have the right to investigate and possibly reject a warranty claim if the failure is directly related to and caused by the tuning, (remember not all tuning is the same quality as Blue Flash Tuning) Therefore, for your total peace of mind, all Blue Flash Tuning work is insured and guaranteed. If our tuning causes a failure inside or outside of the warranty period you are covered. It’s exactly why you should choose Blue Flash Tuning for all your tuning needs. Should you lose your tuning files or have parts failure we will be happy to re-install the map onto your car free of charge for as long as you own the vehicle.

If your vehicle has a software upgrade to the engine management ECU via a franchised dealer (often as part of a service) the software upgrade may overwrite the modified files in your ECU. We will retune the vehicle afterwards.

No, in fact quite the opposite, even on a performance tune, if you continue to drive the car in the same way as you did before the upgrade, your fuel consumption will probably improve. Of course if you have a track day motorsport tuning map installed on the car and you are driving the car under the conditions with which full on motorsport tuning is intended you're likely to find a slightly reduced mpg figure. In just about all other cases though, Blue Flash Tuning will improve your vehicles fuel economy.

No, not at all if when tuned correctly. Sadly some engines can be over tuned, "stressing" the engine, transmission, cooling systems, brakes, etc, and reducing the life span and reliability of the car. This is why it's so important to choose the best – choose us! The research and development we carry out ensures all our tuning is of the very highest standard possible.

We take great care to ensure that all of our modifications have no detrimental effect on your car. In a lot of cases the economy tune actually helps to extend the life of components such as the clutch and gearbox by making the delivery of the power far less aggressive and smoothing the overall drive of the vehicle.

There is an increasing number of tuning boxes becoming available via the internet. They work by adjusting the signal of one or two engine sensors thus tricking the ECU in order to increase fuel pressure and/or boost pressure. They often do not achieve anywhere near the figures quoted. A professional remap involves adjusting many tables of data after extensive research and dyno testing, therefore there is no comparison.

The only time we recommend these is when the vehicle is equipped with an ECU that is not or not yet reprogrammable. We can supply premium quality tuning boxes that carry bespoke software for particular vehicle application. Please ask for more details.

Sadly there are “remappers” out there that offer remapping at ridiculously low prices. The low prices are achieved by purchasing cheap generic files often via the internet that are not warranted or tested. They can work fine but they can also completely corrupt an ECU leaving the vehicle as a non-starter and in some cases requiring a new ECU which is never cheap!

At Blue Flash tuning we read the files in your ECU, modify and adjust them totally bespoke to your needs then write them back to your vehicle.

Nearly all modern petrol and diesel vehicles from cars to vans, buses to lorries, tractors to motorbikes have and ECU (Electronic control unit) or PCM (Powertrain control module). These are computers that control the running of the engine. They receive input data from dozens of sensors around the engine and vehicle, then process that data with the use of maps which are in effect graphs to make thousands of calculations per second like in a petrol engine – when to ignite the spark plugs, in all engines – precisely when and what quantity of fuel to inject, how much boost pressure to apply in turbocharged or supercharged engines, the list goes on.

Older vehicles were tuned by making mechanical adjustments to carburettors, fuel pumps and ignition timing.

When electronic fuel injection became popular in the mid 1980s and pretty much standard in the early 1990s, vehicles were tuned by replacing the microchip inside the ECU that contained the maps with a modified microchip. This is commonly called “Chipping” or “Chip tuning”.

From 1996 onwards most vehicles were built with a diagnostic socket or OBD (On-board diagnostic) connector to allow workshops to use computers to communicate with the vehicles computers to diagnose faults. Most remapping today is carried out by connecting a computer to the vehicle and uploading modified software to enhance the vehicle’s performance and/or economy.
