BMW 4 Series Remapping

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.

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.

An engine that is running from a Fine Tune Motorsport Map will not suffer any reliability issues provided it is well maintained. In the highly unlikely event that there is a problem we will look to resolve the issue should it be determined that it was caused by the upgrade. We offer a 30 day money-back guarantee in the event that you are not satisfied with the conversion.

We advise that it is your responsibility to inform your insurance Company of any modification to your vehicle. We are finding that more and more insurance companies are not penalising their customers for saving fuel and recognise our economy upgrades. We can provide a certificate of conformity if required.

The Map alters the fuel, boost, and torque characteristics of the engine by adjusting the fuel pressure, injected fuel quantity, maximum permissible visible smoke limit, boost pressure, and torque limits.

The conversion offers a fully understood alteration to the engine characteristics, whilst still operating with complete feedback control, and within all preset engine sensor parameters.
