WHAT IS REMAPPING?
Most modern vehicles contain an ECU (or Engine Control Unit) that is effectively a small computer which controls how the engine works. Vehicle manufacturers de-tune the engine by setting the software on the ECU to default before sending the vehicle out. This is done due to the manufacturers having to sell their cars all over the world; this means that the software settings on the ECU must take into account different climates, laws & restrictions and varying quality of fuels. Vehicle remapping is basically the modification/replacement of the manufactures default software on a vehicles ECU.
A vehicle remap replaces default software on the ECU, overwriting it with new software which can be programmed to optimize the cars overall performance. This is known as vehicle remapping because the ECU is essentially a program that controls how the engine works. When your car is remapped, the tuned software is plugged into your cars serial port (or OBD port) which then overwrites the engine map with the new version to enhance engine performance. The ability to flash directly through the OBD has brought the tuning industry on leaps and bounds, with constant development on the engine now being much quicker via the flash process; it has enabled Celtic Tuning to develop some of the best software in the world.
There are many reasons to choose vehicle remapping. Firstly, you will notice that your engine responds better when the accelerator is pressed. The overall torque and power will be noticeably increased. Power delivery will be smoother making for a much safer driving experience, which in turn also makes it easier and safer to overtake. During normal driving, you will notice that your MPG is better which not only decreases the cost of fuel that you will have to pay, but it also minimizes your carbon footprint. Throttle response will be improved and the rev range will be enhanced.
Many people say that ECU remapping doesn’t affect fuel usage; however, this is not technically true. Because of the process involved in ECU remapping more fuel is going to be consumed in order to produce the increase in power. If the car is driven in an enthusiastic way after the remap has been carried out then the fuel economy will not increase (and in some cases may decreases). If, however, the driver modifies their driving style to make the most of the increased power and torque throughout the rev range then fuel economy can be increased. A good example of this could be that the improvement in torque produced by the engine after remapping means the driver no longer has to drop down a gear to maintain speed on an incline or may not have to change gear as frequently in traffic. All of these little things add up to an improvement in fuel economy.
Some people have reported engine damage from ECU remapping, but this is exceptionally rare. In order to offer our customers total peace of mind, Celtic Tuning offers a lifetime warranty on the software itself as well as a full 12 month or 30000-mile mechanical breakdown package for vehicles with fewer than 60000 miles or 3 years old.
Chip tuning is the original definition of what modern-day ECU Remapping has become. Chip tuning requires the removal of the Eprom from the ECU and the software is programmed to the chip on the bench. The software inside the chip is what is referred to as remapping, i.e. altering the standard software within a chip. Chip tuning or chipping has become less and less prevalent in the market place as, since 1996, OBD remapping has taken its place enabling remapping to be done via the OBD (on-board diagnostics) port.
We work on all ages of ECU from the early EDC's requiring chip tuning right the way through to modern MEDC17 locked tricore processor ECU's with tuner protection. A Celtic Tuning superchip from Turbo Dynamics can provide you with all stages of upgrade from a basic ECU Remap right up to full engine conversions.
No one can say for 100% certainty that the remap will be undetectable. However, the modification to the software will not show up on any main dealer diagnostic equipment and therefore unless you tell them that it has been done, they will be none the wiser.
The remap will obviously increase the power output of your vehicle and depending on how you drive depends on how reliable it is for you. If you drive it harder then naturally you can expect to decrease the life of your engine but likewise, if you thrashed it without even having it mapped then you would expect this to be the case anyway. The remap does not in any way stress the engine so the remap itself does not affect the longevity, only your driving style. We have remapped modern engines with over 200,000 miles without issue so it is very unlikely that you will get issues.
Depending on what your requirements are and your driving style depends on what your fuel economy will be. If you go for an outright maximum power output and drive it as so, you can expect to see it decrease as it would without the map. If you get the map to increase torque low down and drive conservatively then it is likely that fuel economy will increase. Please note that fuel economy gains are only likely on turbo diesel engines, petrol engines generally stay the same with some reporting slight improvements, never a loss.
The beauty of the remap is that this process is completely reversible without any trace; therefore if within 14 days you want it changed back, we will carry it out free of charge with a full refund. If after 14 days you wish to reverse it then there is a £50 call out charge for the process but no refund will be given unless otherwise agreed prior to the 14 days elapsing.
Most of our remaps cost £250+VAT, however, every vehicle and engine variant differs so please contact us by telephoning01202 487497or emailing usfor a full detailed quote.
Existing modifications can sometimes bring good benefit to enhancing the software so let us know in advance.
Again, let us know what you’re planning so we can advise the best way forward and can even offer great package deals on other performance upgrades.
We have to advise that you inform your insurance companies that the remap has been carried out but as there is no way for them to read this map, it is up to you what you do. It is your responsibility.
As we change nothing on your car other than a software map, there is nothing for us to give a warranty on other than the contents of the software against corruption and faults. If for some obscure reason you suffer a problem, we will do our utmost to help you including returning your car to standard for any testing. We offer a 2-year warranty on the software itself.

Overall, the disadvantages of remapping a car include: Remapping only really benefits turbo engines. There are serious diminishing returns when remapping a non-turbo engine. Engine strain from remapped cars is significantly greater, given the greater speed, power and performance of an engine.What damage can a remap do? ›
Remapping does put extra strain on an engine, but not a dangerous amount if it's done properly. Remapping companies will carefully monitor the temperatures and pressures that remaps put the engine through when developing their products.Can engine remap be undone? ›
In many cases, a car's remap can be reversed. So, if you decide you'd rather have the original software installed back on your car, it's easily done. That said, this won't bring back the warranty you've voided.Can dealers detect remap? ›
Is a Superchips remap detectable by the dealer? In most cases, no. Some manufacturers can tell that something has changed, but not necessarily what. If and when you need to return your vehicle back to the original remap, you will need to do one of the following, depending on your purchase.Can insurers tell if remapped? ›
Motorists often ask, “can insurance tell if a car is remapped?” The answer is no, but they may find out. Insurers don't inspect cars before giving them cover, so, in reality, your insurer won't randomly check your car for remapping even though some policies may say the insurer can inspect a vehicle if they want to.Will a remap damage my clutch? ›
A rubbish remap will increase wear and tear on the components like brakes and clutch to an unacceptable level – and heighten the risk of you being left unexpectedly on the hard shoulder. A bad remap can also: Reduce the value of your vehicle. Void its warranty.Does remapping affect fuel consumption? ›
Remapping your car can increase how many miles per gallon you can go, improving your overall fuel economy. As your remapped car will now be able to do extra miles for every gallon of fuel, this means you will find yourself filling up your fuel tank less often, thus lowering your fuel costs.Does a remap take time to settle in? ›
Does a remap take time to settle in? Nope the changes are instant when we remap/tune a vehicle.Does remapping reduce engine life? ›
To answer the question at the beginning, you can rest assured that a car remapping doesn't necessarily affect the engine's longevity; it is simply improving its power and torque outputs. However, it is actually your driving style and maintenance that will ultimately determine how long your engine can last.
As long as the fundamentals of the engine are in good order and the person doing the remap is doing the job properly then no damage should occur. The person doing the job should first run a programme to see exactly what the engine is doing and determine if everything is in order before moving on.Is it worth remapping a petrol car? ›
Remapping can increase both performance and economy in most types of vehicles. Even a car with a 1 litre engine can receive good power gains from a remap, especially if it has a turbocharger. Most modern cars these days have a turbocharger (or supercharger) fitted to the engine.Does a remap delete DPF? ›
Once the physical filter removal has been completed the ECU (Electronic Control Unit) is reprogrammed (Remapped) and any DPF related structures removed from the vehicles software. This will prevent the vehicle from sensing the missing filter and will prevent future DPF regeneration and DPF related warning lights.Does remap damage DPF? ›
A side effect of this is that your engine will run richer, creating more far more soot and diesel particulate (PM) which will could clog the DPF at a much faster rate. This will very likely result in more DPF regens and reduced life of the filter.Is a remap better than a chip? ›
So, if you're wanting to increase your car's performance and efficiency, and you're driving a car built before 2000 then you will need a chip tune. If you're driving a car after 2000, then you need ECU remapping.How can I tell if my car has already been remapped? ›
Although some remapping services leave a sticker on the ECU, this is the only visual clue that changes have been made. You could refer to your car's user manual and compare the acceleration and performance of your car currently with the figures in the booklet.Is a remap traceable? ›
Whilst the remap is undetectable to dealer equipment, you should notify your insurance company of any modification to your vehicle.Do remaps void warranty? ›
A car remap WILL void your engine's warranty, If you have heard different elsewhere, then you've been lied to. Car manufacturer warranties clearly state that modifications to any components that are not approved by the OEM will void their warranty. A car remap not approved by your OEM falls under the above.How long does a car remap take? ›
Generally, it can be completed in less than an hour. In fact, a qualified specialist should be able to remap the engine in about 30 minutes.Is Stage 1 remap safe? ›
Stage 1 is the level of remapping that Remap Kings use as it is the only safe level for your car, allowing us to guarantee our work on your vehicle.
Remap lost after visit to dealer? If you have had some work done to your remapped car at a dealership and your car feels noticeably slower than it did before, then there's a good chance that the reason for this is that your remap has been wiped off the ECU by the dealer.Does remapping affect gearbox? ›
Whilst a remap will add a small amount of extra strain to the vehicle, all of our files are well within the safe parameters of the vehicle's components (such as the engine & transmission/drivetrain) capabilities.Does remap change top speed? ›
Remapping a vehicle can also have an immediate effect on speed and power; in some cases, remappers claim to have increased horsepower by 30-40bhp, and torque up to 80nm! A car's engine can also become more responsive, allowing the driver to overtake more easily.How much bhp will I gain from a remap? ›
You can expect a 20-30% increase in bhp and torque after a remap. This extra performance is accessible across the rev range, particularly at low revs and in the mid-range. A typical 30-70mph run will be reduced by 1.5-2 seconds, and your car will pull better at higher speeds.Do you have to tell your insurance if you get your car remapped? ›
Remapping is considered a modification and is, therefore, a change in what you had originally insured with the insurance provider. If you do not tell them, at the very least you may invalidate your policy, but you could also be in trouble legally for hiding information from your car insurance provider.Does remapping affect service? ›
Quite simply, yes. A car remap will void your engine's warranty (including the turbo or supercharger), and it may also void your clutch and gearbox warranty too.Does remapping affect tax? ›
“Any post-registration remapping by a third party may (or may not) have fuel economy benefits but will not result in a changed rate of benefit-in-kind taxation.”How many stages can you remap a car? ›
These days there are commonly three levels of car remapping, known as Stage 1 remap, Stage 2, and Stage 3. Whilst some (mainly us oldies) don't want to embrace it, it's something that tuning companies like ourselves have needed for a very long time.Does remap make engine louder? ›
Will remapping my car make it louder? No remapping a car does not make it louder. The car's engine may act differently producing more RPM (Revs per minute) at different and producing more power but does not make it louder.Does remapping fail MOT? ›
But, the reality is that your vehicle will still pass its MOT test after a remap and it will continue to do so for many, many years. How do we know this? Remapping a car is basically fine-tuning it.
Most diesel vehicles will see between 8-15% fuel saving from the remap alone.Is it worth remapping an old car? ›
We're not saying that a remap will shred your engine, but anything that accelerates pre-existing issues with mechanical components is more than likely going to end in tears. So is it safe remapping an older car? Absolutely – so long as your older car is in good knick and is looked after throughout its lifetime.Does a remap increase fuel pressure? ›
Usually, remappers will increase the fuel pressure and inject fuel slightly earlier during the combustion process to maintain peak pressure for longer, resulting in a mid-range power boost and improving the pickup under acceleration.What's the difference between a Stage 1 and Stage 2 remap? ›
Stage 2 mods tend to offer larger power gains than stage 1 but will require additional work on other parts if you want them to work reliably. Like stage 1, stage 2 mods are usually a DIY fit but will require more specialist knowledge and tools.Does remapping delete EGR? ›
Deleting the EGR valve via a remap is basically coding the ECU to not open the EGR valve ever, meaning any issues caused by the EGR valve are ruled out because it will never be used. This means that you dont need to actually remove the EGR valve which would cost a lot of money.Is a remap permanent? ›
In contrastingly, an ECU remap may only take 30 minutes or so to carry out, but the effects are permanent and can only be removed by specialists who know how to use specialised remapping software.What does a Stage 1 remap do? ›
A Stage 1 Remap increases power and torque while also improving fuel efficiency. Removes flat spots and gives a more responsive drive without compromising reliability.Why does a remap cost so much? ›
It's a skilled job, and it can take months of training before somebody is able to go anywhere near an ECU. As such, it isn't a job for DIYers', which means tuners are always in high demand. This demand and supply, along with a lack of high quality tuners, means tuning companies can charge high prices for their service.How much HP can you get from a remap? ›
Increased Performance – If the remapping is successful, you should notice an immediate improvement of the speed and power of your vehicle. Here at AmD Tuning, our remaps have been known to increase horsepower between 30 – 50bhp and up to more than 80nm of torque. This number will vary on your vehicle's engine.What Is a Stage 2 remap? ›
Stage two performance remapping employs a quality exhaust system with a good air intake filter or induction kit. Typically, with a stage two performance upgrade there is a sizeable increase in amount of usable power and a significant increase in the performance and drivability of your vehicle.
An obvious question that most people ask about our ECU remapping service is “Will it damage my engine?” The short answer is No!How much bhp do I need to remap? ›
You can expect a 20-30% increase in bhp and torque after a remap. This extra performance is accessible across the rev range, particularly at low revs and in the mid-range. A typical 30-70mph run will be reduced by 1.5-2 seconds, and your car will pull better at higher speeds.How much HP can a remap add? ›
What effects can a remap have? By changing the ECU software, the engine can perform a lot closer to its own maximum capabilities - often by increasing horsepower and torque by 20% or more! By default, most vehicles have their performance intentionally dialled down when they leave the factory for a multitude of reasons.Does remapping use more fuel? ›
As the result of ECU remapping, a car usually sees an increase in power, which can come at the expense of higher fuel consumption.Can you tell if a car is remapped? ›
There are a couple of ways for a remap to be detected. The most cost effective and most commonly used method by manufacturers is to check the CVN with diagnostics tools. If an ECU has a different CVN than it should, a manufacturer's diagnostic tools will be able to detect this.How long does it take for a remap to kick in? ›
Depending on the vehicle, the remap normally takes less than 1 hour to complete. 2. IS IT SAFE FOR THE VEHICLE? Our Quantum re-mapping process enhances and optimises the power of the engine within safe limits, not beyond them.Is a Stage 2 remap worth it? ›
Importance: Stage 2 remap is one of the most favourable modifications for a vehicle. It is because it lies in the mid of Stage 1 and 3; it means that you will not regret getting small lower gains after getting stage 1 remap and will not worry if you do not want to take a risk of stage 3 to remap.Are Stage 1 remaps worth it? ›
increase in performance for over 60 percent less, all on the car's original components. Stage 1 tuning therefore is the best pound-for-pound performance upgrade on the market – and if you want more power, you can always add those other upgrades in the future to create a stage 2 vehicle.
