A quality remap from a professional remap company can completely transform the way your car performs, and it’s a modification that has become much more popular in recent years. Below, we’ll break down the top reasons to remap your car engine, as well as the methods involved.
What is Engine Remapping?
First things first: what is engine remapping? In short, remapping involves altering the engine control unit (ECU) – the computer that manages how your engine runs. By making adjustments to your car’s software, such as fuel injection timing, boost pressure, and fuel-to-air ratios, a remap company can optimize the car’s performance without physically modifying engine components. It’s the smart, software-based way to get the most out of your engine, and when done correctly, it can feel like you’re driving a new car altogether.
- Gain Extra Power
It’s no secret that remapping your car can unlock extra horsepower and torque. Manufacturers tend to build engines with a degree of ‘headroom’ in power output, meaning they have more power than the stock settings might indicate. By remapping, you’re essentially unleashing some of that hidden potential.
- How It’s Done: A professional remap company will upload a new software file to your ECU, modifying various engine parameters to increase horsepower. This is especially effective on turbocharged engines, where boost levels can be safely raised.
- Example Result: You could gain an additional 20-30% in horsepower and torque depending on the car. For instance, a remap might boost a 150 hp car to around 180-200 hp, with noticeable improvements in acceleration and top-end performance.
- Improve Fuel Economy
While some enthusiasts remap purely for power, it’s also possible to remap for fuel efficiency. Yes, a remap can result in fewer trips to the fuel pump, especially if you drive a diesel vehicle.
- How It’s Done: By fine-tuning the air-fuel mixture and optimizing fuel injection, a remap company can help the engine run more efficiently. This means better fuel combustion, and in turn, more miles per gallon.
- Example Result: You may see anywhere from a 5-15% improvement in fuel efficiency, depending on your driving style and the type of vehicle. Diesel engines tend to benefit the most from economy-focused remapping.
- Smooth Out Throttle Response
One often-overlooked benefit of engine remapping is the improvement it can bring to throttle response. A standard throttle response can sometimes feel sluggish, particularly in turbocharged cars where a delay (known as ‘turbo lag’) can occur before the engine reaches its peak power. Remapping helps reduce this lag and makes throttle response much sharper.
- How It’s Done: By adjusting the ECU to reduce delay in throttle input, a remap company can create a more responsive and enjoyable driving experience.
- Example Result: Imagine pressing the accelerator and feeling an instant response – remapping can help bring the car’s throttle response to life, making it feel like it’s eagerly waiting for your next move.
- Improve Towing Capabilities
If you use your vehicle for towing, then remapping could make a substantial difference. Towing places extra strain on an engine, so the additional power and torque from remapping can help make it feel more stable and powerful when pulling a trailer or caravan.
- How It’s Done: Remap companies will often increase torque at lower RPMs for towing-focused remaps. This helps the vehicle handle heavy loads more easily without the need to rev the engine hard, reducing stress on the engine and increasing control over the load.
- Example Result: You’ll find that your vehicle can handle steeper inclines and heavy loads with ease, making towing safer and more efficient.
- Customize for Your Driving Style
Engine remapping is highly customizable. When you go to a professional remap company, you can specify what kind of performance you’re looking for. Whether you want something more aggressive for spirited driving or something smoother and more refined, a good remap can cater to your exact needs.
- How It’s Done: The technician will consult with you, discuss your goals, and create a custom ECU map that aligns with your driving habits.
- Example Result: The final remap will suit your specific preferences, whether that’s better city efficiency, smoother motorway cruising, or more responsive acceleration.
Methods of Remapping
While the reasons for remapping are compelling, it’s also essential to understand the different methods available:
- OBD (On-Board Diagnostics) Remapping
The most common remap method is done through the OBD port, a small plug located near the driver’s seat. A remap company can connect directly to your car’s ECU through this port and upload the new software file.
- Bench Remapping
In some cases, remapping via the OBD port is not possible due to a locked ECU. In these situations, bench remapping may be used, which involves physically removing the ECU and connecting it to a programming device.
- Custom Tuning
For high-performance cars or those looking for specific power gains, custom tuning can be tailored to your car. This involves dyno testing and custom adjustments to create a bespoke map that maximizes performance for your specific vehicle.
Choosing the Right Remap Company
A quality remap makes all the difference, and the last thing you want is a subpar remap that could risk engine reliability. When looking for a remap company, consider one with a solid reputation, experienced technicians, and good customer reviews. Don’t be tempted by bargain remaps from questionable sources; quality remaps use carefully developed maps that are specific to your make and model.
Is Remapping Safe?
This is one of the most common questions people have, and it’s understandable. When done correctly, a remap is perfectly safe and can improve engine reliability in some cases. That said, there are some risks if the remapping isn’t done professionally. A reputable remap company will ensure that all adjustments are within safe limits and won’t negatively impact engine health.
The Takeaway
In a world where technology continues to redefine our driving experience, engine remapping has become an accessible and worthwhile upgrade for many drivers. From power gains and fuel efficiency to improved throttle response and towing capabilities, a remap can breathe new life into your car. Just make sure to choose a remap company you can trust, so you get a reliable, expertly crafted remap that will stand the test of time.
