FAQs

Feel free to contact us if this section doesn't answer your questions.

Q. Why does a turbo-charged vehicle gain so much more power as a result of tuning / re-mapping than a normally aspirated vehicle?

A. The turbocharger is a device for compressing air into the Engine Cylinder above atmospheric pressure. The level to which it is pumped is determined by the turbocharger size and the waste gate actuator. This conditioned air allows much more fuel to be burnt within a given cubic capacity cylinder size than can be achieved under normal atmospheric pressure. The engine management system is modified in timing and fuelling so that the engine effectively responds as if it has larger CC. This extra air/fuel can achieve in some instances 100% more power and torque through re-mapping. The normally aspirated engine can achieve 10% more power and torque by careful programming of fuel pulse and ignition maps and further power is available if camshafts, exhaust pipes, air filters and high octane fuel are in use.

Q. Why was my vehicle not given this extra power from the factory?

A. The engineers who developed the engines know this extra power and torque is available, however, due to some engines enormous operational range encountered around the world such as varying fuel octane, air temperatures and altitudes a safe all round compromise is adopted by the manufacturers to suit all these conditions and fuel economy and exhaust emissions regulations. Compromises are also left in the programmes to cater for the owners who refuse to follow service schedules and insist on using the worst fuel possible. Our task as a Re-mapping company is to clear these compromises and produce a program more suited to the enthusiastic driver who looks after their vehicle and knows what they want from an engine. We optimise the software that runs your engine in many different ways, yet we still leave the reserves necessary to assure absolute reliability.

Q. In what rpm range is the extra power released?

A. On most vehicles you will feel the power over the entire power band of the engine, but especially in the lower and middle rev range.

Q. What about my fuel consumption?

A. With same driving style, improvements in fuel consumption of up to 20% are possible, especially in turbo diesel powered engines.

Q. Can I use my original ecu software again?

A. All that is changed is the software within your ecu. We keep a copy of your original software on file so we can simply programme it back should you require us to do so.

Q. Will I need to upgrade the chassis or brakes?

A. On 90% of vehicles, you don't need to upgrade the chassis or brakes after the re-mapping.

Q. Can the re-map be detected by dealer servicing?

A. No not normally. Your car dealer cannot determine a software modification with his equipment, since our software is designed to be invisible to all engine diagnostic equipment. However we understand that VW/Audi dealers may have diagnostic equipment caplabe of detecting ECU modifications.

Q. What if I get the work done and I dont notice a difference?

A. You really will! But if you are not happy and you genuinely don't notice a difference we will retirn your ECU to the original map and we wont take any money from you.

Q. Are you insured?

A. Absolutely. We have full public & product liability insurance.

Q. Are these generic maps? Should I be having a custom map?

A. These maps are not generic maps, they are tailored to your specific engine and are based on a your original ecu map's, they are then tweaked to get the best out of your engine. We develop many maps in house but also work with many mapping specialists to enable us to offer the best possible remapping options for the widest selection of vehicles. For higher stages of tuning, for very highly modified vehicles, the maps are more expensive due to additonal data logging and testing required.

Q. My Airbag/Engine Management light is on. Can you help?

A. If you own a post 1997 car from the VW/Audi Group (VAG - VW Audi Seat Skoda) then we can read the fault codes and in a lot of cases clear them. Sometimes the ecu throws a fault code as a one off rather than because of an actual problem. This then lights the warning light. Clearing the code usually makes the light go out. This isn't a bodge, if there is a genuine problem the light will come back on. Reading the fault code we can diagnose the problem and advise on how to repair. Please note we are not a garage so we won't be scouting for work.

Airbag lights are similar to fault codes. Something as trivial as movign the seats too fast can sometimes cause the lights to come on.

Q. Will the remap be lost if i have to disconnect the battery?

A.  The remapping changes a software file in the cars ECU, so you will not lose the remap should you disconnect your vehicles battery.

Q, How will a remap affect the longevity of my engine?

A.  The engine in your car was built to offer more performance than it left the factory floor with. Manufacturers play it safe with power and torque and intentionally hold back when writing their own ECU software. 

The reasons for this are two-fold. Firstly, they do it as a safety net against poor maintenance, knowing full well many drivers do not treat their car well. Their customers might miss service intervals. They might not let the engine warm up properly before driving hard. They might fill up with poor quality fuel. These things can be balanced out in software to a point to keep customers on the road. Part of that balancing is limiting power and torque to reduce stress on mechanical components. 

Secondly, manufacturers have strict emissions targets to meet. They have to manufacture cars that will pass emissions tests without hiccup. Additionally, the new WLTP testing cycle pulls no punches in shaming inefficient cars. Manufacturers play it safe as a result. They do this by reducing fuelling which reduces horsepower and torque. The WLTP cycle is performed in a lab and does not suit high performance, which is in contrast to the real-world, where more power and torque can actually improve fuel economy because you don’t have to work as hard to get up to or maintain speed. 

Because the engine in your car was built to offer more performance than it left the factory floor with, it can handle more power and torque. This is a fact. When remapping is carried out professionally, it is a safe and harmless modification. 

Cars with forced induction (turbo, twin-turbo, supercharged, etc.) can see a power and torque increase of 20% with very little additional stress to mechanical components. Some can be dialled up more than 30%. To point out the obvious, the mechanical reliability of an engine depends on how it is treated and maintained. If you drive your remapped car at full pelt all of the time, it’ll eventually go bang but then so would a standard engine. Mechanical sympathy is always required, irrespective of tuning. 

Finally, we cannot stress enough the importance of choosing a reputable tuning shop to remap your car. We have been called out to some disastrous jobs with cars misfiring, knocking, smoking like mad out of the exhaust and just driving like a bag of spanners. Your car after a remap should drive as smoothly as it does stock but with more power under your foot. There should be a noticeable increase in performance with no gaps in power, jerkiness or trouble starting up. Everything should feel spot on.
