The MAX TUNE remapping process enhances and optimises the power of the engine within safe limits, not beyond them. Extra power will also result in fewer gear changes, which may actually reduce overall wear.
Manufacturers build in a tolerance to manage the effect of wear and tear on engine parts, production variations and to ensure their warranty claims during their warranty period (normally 3 years) are kept to a minimum. Most race and rally engines are pushed for every last BHP and are therefore more likely to fail. Whilst normal car / van / lorry engines are limited well before multiple failures become likely, each individual engine is different in how far it can be pushed as a result of a remap. A good remap from a quality tuner like MAX TUNE will never get close the limits of component failure.
You may have seen that the other tuning companies within the market place quote vehicle improvements at higher outputs for similar vehicles. Beware of tuners who claim significantly more, it may be that the engine will be pushed too hard and become unreliable.
Manufacturers generally sell one vehicle to various markets. Markets in different geographical regions have different tax and emissions regulations, climates (including extremes of temperature and humidity), fuel qualities, operating altitudes, etc. A manufacturer has to take all of these factors into consideration and make substantial compromises in the vehicles operation. We aim to optimise the engine performance.
We offer a 2 year warranty on software faults. A professionally remapped engine will not cause technical faults with a well serviced and maintained the engine.
The only way to tune your vehicle for improved performance or economy, within the correct parameters of safety and durability, is to make changes to the existing control system of the engine. That is what we offer with an MAX TUNE remap. Our remapping service is a carefully controlled process and does not disturb the safety functions of the car.
Apart from the obvious power, torque and fuel economy benefits, the additional advantages of an MAX TUNE remap include the following:
Installation is usually completed within 2 hours.
There are no loose boxes or wiring flexes in the engine compartment.
Torque is delivered smoothly throughout the rev range.
Torque is adjusted / limited in lower gears to avoid transmission damage.
Boost pressure and air flow is optimised.
The original settings (or map) can be reinstalled if required.
The on board computer shows the correct fuel consumption, unlike tuning boxes that can give false readings.
The Electronic Stability Program (ESP) function is fully retained.
Correct calculation of exhaust temperature.
Correct calculation of service interval.
The diagnostic system remains intact.
No increase in emissions.
Yes, we keep a copy of the original maps. You can request that we reinstall your original map at a later date if you need to.
The official line from most manufacturers is that if a modification causes a problem with the vehicle, then the part of the vehicle affected will not be covered under warranty. This does not necessarily mean a unilateral cancelling of the whole warranty.
Standard diagnostic equipment cannot detect an MAX TUNE remap. We can also return your vehicle to stock (reinstall the original map) if you would like us to for any reason via our AUTHORISED DELAER network or if you have our truetune.
A MAX TUNE remap offers a fully controllable change to the engine characteristics, whilst still operating with full engine feedback control and within all the pre-set engine sensor limits.
We never use or fit add-on tuning boxes. They usually work by interfering with engine management signals to trick the injectors into adding more fuel. Our services involve a custom remap of your ECU, specifically for your vehicle.
A tuning box relies on the principal of more fuel equals more power. The theory is correct. However, in practice they are unable to control a correct air to fuel ratio, resulting in too much fuel and excessive black smoke. The black smoke is un-burnt fuel exiting through the exhaust system and has no affect on power gain. A tuning box raises emissions and increases the thermal load on the engine. A tuning box sends false signals to the ECU, preventing the ECU from working correctly to protect the engine and to maintain safety.
Torque is the twisting force created in an engine by the rotating parts. Horsepower is the measurement of how fast torque is being used. Horsepower and torque work hand-in-hand, as horsepower is calculated from torque.
It is easier to accelerate and sustain speed with a high-torque vehicle in any situation. However, high-torque vehicles are particularly good for towing or hauling heavy loads.
Brake horsepower (BHP) is the amount of power generated by a motor without taking into consideration any of the various auxiliary components that may slow down the actual speed of the motor. Brake horsepower is measured within the engine’s output shaft. Depending on the configuration of the engine, the point on the output shaft that is the focus of the measurement is the engine dynamometer.
The reference to this type of horsepower measurement as brake horsepower has its origins in the braking systems that were used on some of the first automobiles in the early 20th century. Many cars were equipped with a hand brake that would slow the forward projection of the vehicle. This same hand brake was also used in the manufacturing process to gauge the amount of torque created within the motor, making sure the output was within acceptable limits.
In the actual calculation of brake horsepower, it is necessary to consider the total load of the electric motor. This means disregarding any drain on the power that is due to the water pump, generator, or the gearbox that work in conjunction with the motor of the vehicle. The amount of power loss that occurs due to the action of various belts and pulleys is also added back into the base figure, making it possible to determine the true amount of pure horsepower being generated by the motor.
The Newton meter is a unit of torque (also called “moment”) in the SI system. One Newton meter is equal to the torque resulting from a force of one Newton applied perpendicularly to a moment arm which is one metre long.
