Frequently Asked Questions
Our remapping enhances and optimises the power of the engine within safe limits. We are taking up the slack of the high tolerance level that vehicle manufacturers always build in – often to ensure that warranty claims are kept to an acceptable minimum. A good remap from a file writer who understands the strategy within the ECU will not allow the engine to get close to component failure.
Note that quality tuning companies offer very similar gains – so be wary of some with a lesser reputation, who appear to offer enormous power increases. In reality these claims are either simply untrue, or they are programming the ECU well outside of safe operating parameters. Every vehicle has a mechanical limit to the amount of power it can produce, so if it sounds too good to be true it generally will be.
Most race and rally engines are pushed for every last bhp, and thus they more common to fail, whilst normal car/van/lorry engines are limited back, well away from probability of multiple failures. Each individual engine is different as in how much it can be pushed in a remap, but a good ecu remap from a quality ecu tuner will never get close the limits of component failure.
A manufacturer cannot risk selling a vehicle on the very edge of performance, so engine management calibration is a compromise: it has to take into account regional differences for fuel quality and operating conditions.
The way an engine delivers its power and driveability is also subject to sales and marketing constraints, to ensure it is portrayed in the best light possible when compared to its rivals. Marketing departments within the big vehicle manufacturers wield a surprising amount of influence; if they demand that a torque curve should look a certain way because they believe it gives them a sales advantage, they tend to get what they want – despite realistic opposition from those who actually calibrate the car.
By far the most effective way to increase the performance of a diesel-engined vehicle is to carry out a remap, which does not require any hardware changes and leaves the existing systems (such as ABS and stability control) unaffected.
Our modifications are only carried out on engine calibration parameters; and because we understand the strategy that the ECU is programmed with, the conversions we make are not ‘fooling’ related systems. This means that:
- Nothing needs to be connected to the vehicle after tuning
- No loose boxes and wiring are left in the engine compartment
- Torque delivery is smooth
- Torque is adjusted/limited in lower gears to ensure transmission system longevity
- Boost pressure and air flow is optimised
- Infotainment systems will display correct fuel consumption
- Traction control / stability systems are unaffected
- Torque reduction when shifting gear (for comfort and durability) is retained
- Regeneration of the diesel particle filter (DPF) is retained
- Exhaust gas temperatures are correctly calculated and applied
- Service intervals are correctly applied
- The diagnostic system remains unaffected
- No enlarged NOx, HC, CO, CO2, or soot emissions compared with original when undertaking MOT testing
- The original calibration can be reinstalled if required
Some diagnostic equipment may detect a remap, although some forward-thinking manufacturers turn a blind eye to a quality conversion.
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; but this does not mean that they can disregard the entire warranty. If, for example, your vehicle’s central locking system failed, they would not be able to void the warranty because of the remap.
