What is a Stage 1 remap?

So, you are looking at getting a stage 1 remap for your vehicle..

In this blog we explain what a stage 1 remap is, the costs and look at how much bhp a stage 1 remap adds to your standard, unmodified vehicle.

Further down the blog you will see a vehicle gain checker. Use this to find out your vehicles potential power gains.

A detailed break-down of a stage 1 remap?

A stage 1 remap is a software upgrade for your car’s engine computer unit (ECU) that can improve fuel efficiency along with improving performance with no hardware upgrades required. The ECU controls the air-fuel mixture and ignition timing along with valve timing and fuel injection timing. A stage 1 remap can be applied to modern cars, with both petrol and diesel engines.

Stage 1 car remapping is a software-only engine calibration with no required hardware upgrades. Software calibrations are made through the Engine control unit (ECU) by plugging software calibration equipment into the OBD port such as the ‘Kess3 OR CMD’, or by removing the ECU and ‘benching’ the unit with the calibration being carried out by hand on the ECU circuit board with pins transmitting the tuning software from tool to the vehicle.

A stage 1 remap can adjust ECU settings to provide better fuel efficiency with economy tuning or more power and torque with performance tuning all without compromising the reliability of your vehicle.

With no hardware upgrades, engine remapping can achieve the following benefits:

1.) Increase Power and Torque

2.) Improving Fuel efficiency / improved mpg

3.) Improve Performance and Drivability

4.) Improved Throttle Response

How much bhp does a stage 1 remap add?

Some tuning customers request improved mpg with economy tuning due to rising fuel prices, with others requesting stage 1 car remapping for power and torque gains, improving the performance and power of their vehicle. So, how much bhp does a stage 1 remap add? below you can use our tuning database to find your vehicle and compare the before and after gains of a stage 1 remap.

All of the tuning figures both before and after have been recorded an a rolling road, also known as Dyno / Dynometer. A static device recording a vehicle’s wheel rotation to give accurate readings of BHP and Torque.

But what are the benefits of a stage 1 remap? and how do they individually affect the vehicle’s performance?

1.) Improved power and torque

Most modern cars are fitted with a turbo whether it be diesel or petrol. A safe and sensible stage 1 remap session will ensure that the engine is calibrated inline with your engine’s safe parameters.

Stage 1 remaps are a great way to improve the performance of your vehicle. By recalibrating the ECU, you can make the most out of any modifications you have made, such as a sports exhaust or air intake. And because they are safe for engines with no other modifications, stage 1 remaps are a great way to get started with tuning your vehicle. So if you’re looking for a little more power and torque to improve the performance of your car, look into getting a stage 1 remap.

The Stage 1 remap is achieved by recalibrating the ECU. This is done by connecting tuning equipment to the ECU via the OBD port, or by removing the ECU from the car and ‘benching’ it to work on it manually.

Either way, a Stage 1 remap is a simple and effective way to improve your car’s performance without breaking the bank.

2.) Improved fuel efficiency

A Stage 1 remap can help to improve fuel efficiency in a number of ways.

By improving the power and torque delivery of the engine, a Stage 1 remap can help to make the car more efficient in its use of fuel. For example, a Stage 1 remap will improve the vehicle torque, providing more power lower down in the rev range, subsequently reducing the amount of time it takes for your vehicle to get from standstill to cruising speed. Additionally, cruising speeds can be maintained easily. All of these factors combined can lead to significant fuel savings, making a Stage 1 remap an excellent way to improve fuel efficiency.

3.) Improved performance and driveability

Stage 1 engine remapping improves not just the BHP and Torque but the overall driving experience of your vehicle. There is no need to use a specific fuel grade or enhance the exhaust system to reap the benefit of a stage 1 remap.

Common complaints with underperforming stock vehicles include, struggling to get up steep hills, poor overtaking and struggling to get up to speed to join the motorway. All of these issues are caused by a lack of Torque and BHP which can both be relieved with stage 1 tuning. You will also experience smoother gear changes, as the increase in torque carries the vehicle into the next gear with more power, along with improved mpg at cruising motorway speeds as the vehicle is able to maintain speed without struggling for power.

4.) Improved throttle response

Your car’s engine has an ECU (engine control unit) that is programmed to perform a number of tasks. One of the ECU’s jobs is the manage the (ETC) electric throttle control which is responsible for throttle response when the driver applies pressure to the pedal. In modern vehicles, there is a brief delay between stepping on the peddle and the power kicking in. This occurs as modern systems no longer have a physical throttle cable linking the engine directly to a driver’s foot action. Software-enhanced throttle response creates a delay to reduce juddering and provide a smooth driving experience.

The throttle response being linked to the ECU does however mean that it can be calibrated. A stage 1 calibration includes throttle response development making your electric throttle control as effective as an old-fashioned wired throttle body. When you push the pedal, the car responds instantly, improving driving experience.

Looking for more than just stage 1 remap performance?

A stage 1 ECU remap will provide significant power gains to all turbo diesel vehicles. If you are looking for more power, a stage 2 remap is the answer. This remap will offer incredible gains. Stage 2 remap calibrations need a hardware vehicle modification or two to in order to make the most of the tuning set up. These hardware upgrades include sports exhaust, intercooler and air intake.

Choosing the right Stage 1 Remap calibrator/ Remapper

Be sure that the ECU tuning company you choose to work on your vehicle is personally making the adaptations to the ECU software.

Third-party software calibrators are often hired by backstreet tuning companies to tweak ECU calibrations without rolling road data to make the engine remap bespoke to your vehicle and its condition. This could affect the performance and power of your vehicle and put your vehicle at risk of being damaged.
