Our technicians have put together a list of popular questions they are always being asked. We hope this helps you make an informed decision.
Our technicians link to the vehicles ECU or ‘brain’ with a laptop through the vehicles diagnostic socket and download the data stored within. This is then optimised for you requirements. The technician programs the new optimised data into your vehicle and you then have the opportunity for yourself to experience the amazing results.
On some vehicles it is not possible to carry-out this function by the diagnostic socket, in this case the ECU is removed and either a chip changed or a boot loading function is carried out direct into the ECU. The final effect is exactly the same, only the process is different. Depending on the requirements, the process normally takes less than 1 hour to complete. For advanced levels of programming which take a lot longer to do the technician may download the data and return at a convenient time to upload the new data. Your vehicle will be fully useable in the meantime.
EngineTechs state of the art re-mapping process enhances and optimises the power of the engine within its safe limits, not beyond them. Extra power will also result in fewer gear changes, which can actually reduce overall wear. Manufacturers have to build in high tolerances for the parts in the engine, to manage the effect of wear and tear, production variations, poor fuel quality and to ensure their warranty claims, during their warranty period normally 3 years, are kept to a minimum. Each individual engine is different as in how much it can be pushed in a remap, but a good remap from a quality tuner like EngineTech will never get close to the limits of component failure.
You will see that the top companies within the market place have all developed vehicle improvements to similar outputs. Beware of tuners who claim significantly more, it’s either lies, hoping that the average customer wouldn’t be able to tell the difference, or the engine is being pushed too hard and will quickly become unreliable.
Manufacturers generally sell one vehicle that covers various markets, with different tax and emissions regulations, different climates with extremes of heat, cold, humidity, different fuel quantities, different operating altitudes, etc.
A manufacturer has to take all of these factors into consideration and make substantial compromises in the vehicles operation. EngineTech optimise the engine tuning and outputs to suit the vehicles location & the drivers needs.
Every EngineTech remap is guaranteed to ensure your complete peace of mind and continued service. We offer a lifetime warranty against software faults. If the installation becomes faulty, we will re-install it free of charge.
A professionally remapped engine will not cause technical faults with a well serviced and maintained the engine.
EngineTech are very confident that your remap will both improve your driving experience and save you on fuel, but don’t take our word for it, try the upgrade for 14 days and if you are not delighted with the results, EngineTech will remove it and reload the original.
An EngineTech remap alters the fuel, boost and torque characteristics of the engine. By controlling the fuel pressure, injected fuel quantity, maximum permissible visible smoke limit, boost pressure from the turbocharger and the torque characteristics.
An EngineTech 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 do not fit add-on tuning boxes, which normally just interfere with engine management signals to trick the injectors into adding more fuel. Our service is a custom re-map of your ECU, specifically for your vehicle.
These differ from how a remap works. A tuning box relies on the principal of more diesel fuel = more diesel power. That theory is correct and boxes do increase power, but they can’t control the amount of black smoke (maximum permissible visible smoke limit) coming out of the exhaust.
Too much smoke is undesirable, both environmentally and visually. More importantly, the black smoke is un burnt diesel fuel attached to combustion chamber, with deposits exiting straight out of the exhaust pipe, thus wasting fuel which hasn’t had any effect on power gain. The results are raised emissions, a higher thermal load on the engine (i.e. exhaust temperature) and frequently defects such as "bucking" are often the result. It should be clear what this means for your engine.
In a modern engine there are complex engine control systems that cooperate with each other to make everything work perfectly. A diesel box manipulates some signals in order to either increase the injection time or fuel pressure. Unfortunately this manipulation is done entirely without the engine control system’s knowledge. This means a diesel box tricks the engine control system of the vehicle and the consequence is a large amount of values and control data will be incorrect, resulting in:
• The on board trip computer shows improved fuel consumpation, but the real amount left in the tank is less, as fuel is being injected without any of the sensors detecting the additional amount entering the cylinder.
• The anti skid program (ESP) is disturbed because of incorrect torque value
• No loose boxes and wiring flexes in the engine compartment
• The automatic gearboxes get incorrect torque value
• Torque reduction when shifting gear (for comfort and durability) is not retained
• The regeneration (emptying) of particle filter will not be optimal
• The calculation of exhaust temperature is disturbed
• The calculation of service interval is disturbed
• The diagnostic system is disturbed
Torque is the twisting force created in an engine by 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.
For the average buyer, torque shouldn’t be a deciding factor unless you know you’ll be towing or hauling heavy loads. And that’s where high-torque vehicles will do well, driving while towing a trailer or maxing out cargo capacity. It will be easier to accelerate and sustain speed with a high-torque car in any situation, but especially with heavy loads.
High performance cars can also produce lots of torque that greatly aid in acceleration. That feeling of you being forced back into your seat in a fast car during heavy acceleration is an example of excessive torque.
Brake horsepower (BHP) is the measure of an engine's horsepower before the loss in power caused by the gearbox, alternator, differential, water pump, and other auxiliary components such as power steering pump, muffled exhaust system, etc. Brake refers to a device which was used to load an engine and hold it at a desired rotational speed. During testing, the output torque and rotational speed were measured to determine the brake horsepower. Horsepower was originally measured and calculated by use of the "indicator" (a James Watt invention of the late 18th century), and later by means of a De Prony brake connected to the engine's output shaft.
More recently, an engine dynamometer is used instead of a De Prony brake. Although the output delivered to the driving wheels is less than that obtainable at the engine's crankshaft, a chassis dynamometer gives an indication of an engine's "real world" horsepower after losses in the drive train and gearbox. This gives a reasonably accurate indication of how a wheeled vehicle engine will perform once on the road.
A newton meter (NM) is a unit of torque (also called "moment") in the SI system. One newton meter, sometimes hyphenated newton-meter, is equal to the torque resulting from a force of one newton applied perpendicularly to a moment arm which is one meter long.
It is also used less commonly as a unit of work, or energy, in which case it is equivalent to the more common and standard SI unit of energy, the joule. In this very different usage the meter term represents the distance travelled or displacement in the direction of the force, and not the perpendicular distance from a fulcrum as it does when used to express torque. This usage is discouraged by the SI authority, since it can lead to confusion as to whether a given quantity expressed in newton-meters is a torque or a quantity of energy.
