ECU Remapping & Car Tuning is what we do, and what we do well. For everyone at BHP UK, car remapping, engine chip tuning, remapping motorbikes, trucks (and even tractors!), isn’t just our business, it’s our obsession. However, we do understand that not everyone can be a genius like ‘all’ the staff are at BHP UK and we also understand that there are always going to be questions which you might need to ask… This is why our boys (and girls) have come up with a list of the most commonly asked questions that they get asked (and are sick of answering!). If you still have a question that you need answering, then please do not hesitate to get in touch. And we would love to answer any question or query you may have.
Q: What is an ECU?
A: An engine control unit (ECU), is also known as a PCM (powertrain control module). This is an electronic control unit, which controls actuators on an internal combustion engine to help the engine run at optimum.
Q: What is ECU Remapping?
A: ECU remapping is a tuning procedure of the engine, that allows several manufacturer constraints to be lifted from the vehicle. Sound confusing, click here for more information on what ecu remapping is & why these limitations are placed by vehicle manufacturers.
Q: If my car can be improved so much by an ECU Remap, why hasn’t the factory done this?
A: This is a very common question that we get asked. The answer is very simple, the factory could have remapped your car, however they choose not to for many reasons, the most important is marketing. Cars are manufactured to fit into a market category and there is certain criteria for make & model categories and the car’s ECU is mapped to fit into these categories. It also allows for a enough power separation between various models. Manufacturers will also produce two identical cars with identical engines, then simply offer the car in two states of tune, this is a very economical way of extending a model range. Examples of such cars include the BMW Mini One and the BMW Mini Cooper, another example is the VW Golf Tdi 104BHP and the Golf TDi 140bhp.
Q: Will ECU tuning put my engine under more stress?
A: We always remap with consideration for the engine and never exceed the engine’s limits.
Q: Is it possible for me to choose a map to suit my driving style?
A: Yes, as we have our own in house map writers we can gear our maps to our customers’ requirements, whether that be for economy, all out power or for towing purposes.
Q: Will my engines life expectancy be shortened?
A: No, we map the ECU to optimise the performance without exceeding your engine’s limits.
Q: Can my car be reverted back to original, should I need it to?
A: We can always return your car to standard should you ever need it to.
Q: Will you need to dismantle my car ECU to program it?
A: Normally on most modern cars we can reprogram the ECU through the car’s OBD port
Q: Will I need to upgrade my brakes after a remap?
A: On most cars the brakes can easily handle the extra power. However, should you want to upgrade your brakes we can advise & supply upgraded pads, discs and calipers.
Q: What makes and models can you remap?
A: We remap all makes and models. If you can’t find the car make or car model you are looking for, please don’t be disheartened. Give us a call and we will definitely be able to find you a solution for your car. The following makes are just a few of the ones we remap: Alfa Romeo ECU Remapping, Audi ECU Remapping, BMW ECU Remapping, Ford ECU Remapping, Honda ECU Remapping, Land Rover ECU Remapping, Skoda ECU Remapping, Volkswagen VW ECU Remapping and many more.
