Frequently asked questions.

What is a stage one remap?

A stage one remap is an adjustment to the engine control unit (ECU) of a vehicle. Think of it as your car’s personal computer. It tells the car how much power it can use. A stage one remap will override the default settings of your vehicle’s ECU, allowing it to draw more power or better fuel efficiency than it would stock from the manufacturer.

What’s the difference between a stage one remap and a stage two remap?

As previously mentioned, a stage one remap is purely a reconfiguration of existing software within your vehicle. The only modification is to the ECU, which tells the engine how to draw more power. Stage two refers to the physical hardware on a car, such as performance exhausts, cooling systems, and smaller turbos. By adding additional performance hardware, you can improve your cars speed, power, and fuel economy. At the current time, we do not offer stage two remaps.

Will a remap affect my cars warranty?

During servicing some manufacturers software will be able to tell if a car has had its ECU adapted, however, this will read as a software update. As such, this could affect your manufacturer or dealer warranty.

Can I have my Remap refitted if it has been overwritten?

On occasion a dealership or Service centre may need to update your ECU’s software, as prescribed by the Manufacturer. This will overwrite your existing software, meaning you will lose your Remap. Remap Kings are happy to reinstall the remap if this should occur, for a callout fee of £50 per visit. If you have any further queries about the ECU software updates and dealer warranties, do not hesitate to contact us.

Why don’t the cars come with this performance from stock?

Manufacturers often use the same engine in a series of vehicles, but allow certain models to achieve their true power so they can retail at a higher value. This is a marketing tactic employed to make you spend more. Manufacturers also have a wide range of rules which they must adhere to so they can produce their cars. These can range from specific emissions tests, to which fuel grades an engine utilises. Ensuring they meet these requirements is vital for manufacturers, and therefore stock engine performance tends to be lower than what it can capably handle.

Can I get a refund?

We offer a 30-day money back guarantee from date of your first fitting. If you’re not completely satisfied with your remap, Remap Kings can remove it from your vehicle and will refund the cost of the remap*. If you pass the 30-day window and wish to have the remap removed, Remap Kings can do this for a call out fee of £50 and an hourly rate of £80 per hour after the first hour. After the 30-day period you cannot not receive a refund.

Be aware that performance gains correspond to the mileage, age and condition of the vehicle, along with environmental conditions and grade of fuel used. We cannot guarantee performance gains for vehicles over 80,000 miles or 8 years old. Performance gains of 20% or less (as specified on our website) may not be applicable for vehicles over 50,000 miles or 5 years old.

Can a remap damage my engine?

All our remaps are dyno tested to ensure they are safe for your vehicle. This means that the extra power your car produces will not surpass the limit the engine can handle. We also carry out a full diagnostics test on your vehicle before remapping to ensure your car gets the most from the performance boost and to ensure that the engine can safely handle the remap.

What is a dead spot?

A dead spot is where your engine lags, failing to produce a smooth increase in power. Often, you’ll experience this when pulling out of a junction, and your car may feel unresponsive, then suddenly take off. Not only is this bad for your engine, but it is extremely dangerous to you and other motorists on the road.

Will a remap affect my insurance?

Insurers are increasingly becoming more accepting of modifications such as ECU remapping. We recommend you inform you insurer of the modification to your vehicle to avoid the risk of a claim refusal. Insurers can, at their own discretion, revoke or void an insurance policy if they discover the modification.

What is KTAG vs OBD Remapping?

There are two primary forms of ECU remapping. These are OBD remapping and KTAG remapping. The end result in both cases is that the ECU is reprogrammed to allow your vehicle to better reach its potential, but there are a few key differences. OBD remapping is the most common - and easiest - form of remapping. It involves plugging our specialist tools into the OBD (On-Board Diagnostics) port in your vehicle, and then installing software onto the ECU. For our highly experienced team, it is simple and safe, and usually takes between 30 minutes and an hour from start to finish.

The second of these - KTAG remapping - is where the vehicle’s ECU has to be physically removed from the vehicle, and then adapted. This is most commonly necessary in older vehicles where the ECU can no longer communicate effectively with modern technology. KTAG remapping is more time consuming, and must be carried out by trained time-served professionals like our Remap Kings team. We remove the ECU, then conduct the work in our fully equipped facilities to ensure there is no risk of damage to your vehicle, and return the ECU the following day with the remap installed. Due to the highly skilled and time-consuming nature of this work, the prices are higher than for OBD remaps.

Please be advised that in the unlikely event that our remap is "detected", this may invalidate your manufacturers warranty.

Please remember that every vehicle is unique and manufacturers will sometimes put different ECUs into the same car and many vehicles have unusual configurations or modifications which are only apparent when reading the ECU. As such, we recommend that you discuss the potential gains and tuning options available directly with our engineer. Remap Kings tuning database is constantly being refined, amended, updated and expanded. Remap Kings is confident that its data is amongst the most comprehensive ECU tuning and remapping data currently available anywhere in the world.

Whilst every effort is made to ensure the data in above table is up-to-date and accurate, it should only be used as a guide. It is possible that the economy and performance gains available are in excess of those stated above, conversely actual gains may be less than the current data suggests.
