-- Introduction -- BMW Engine Remapping -- Common parameters --
Engine remapping is an increasingly popular way of extracting the most from a vehicle in terms of power and performance. We look at the options for your BMW.
When a car is manufactured, there are thousands of settings and parameters that are programmed into the ECU before it reaches the forecourt. These ensure that the engine works as smoothly as possible. ECU remapping adjusts some of these settings and parameters to maximise the power and performance of the car's engine.
You may be wondering why BMW delivers cars where these parameters are not optimised. The general consensus is that this is because they have to allow for drivers who do not look after their cars, using sub-standard fuels, and not following recommended service schedules. Additionally, they tend to program parameters to be middle-range rather than at the top end to allow for different climates and local regulations.
If you look after your car carefully, remapping can remove some of these restrictions and enable you to improve your car's performance.
BMW Engine Remapping
Despite being some of the most powerful cars around, there is still significant potential to improve BMWs using engine remapping. This applies to both diesel and petrol engines.
When BMW make their cars, they deliberately mute the performance in order to meet specific product objectives and restrictions around performance/power. They also do this so that there is demand for upgrades, and so that they can release more powerful models in the future.
What parameters might be changed?
The most common parameters that will be altered during the remapping process include fuel/air ratio, turbocharging boost pressure, throttle pedal control, fuel pressure, and ignition timing.
Benefits and results:
The precise gains from BMW engine remapping will vary based on the exact model but there should be a noticeable improvement in terms of power, choke reaction/throttle response, torque and acceleration. Some remapping options will also result in increased fuel efficiency.
BMW ECU Tuning Kits:
Unichip Europe offers bespoke BMW ECU Tuning Kits that are pre-programmed, equipped with a wiring harness, and are easy to plug in at home. They pose no risk at all to the mechanical components of the engine and can be removed without leaving any trace.
