The core of what we do. We write all our own software in house which gives us an increased edge over a lot of tuners in the industry. Before tuning we carry out a full vehicle health check to main dealer standards to ensure the manufacture reliability comes with the added performance and efficiency. We then create a full back up of your ECU (Engine control unit) and store it on our dedicated server. This is saved in case you wish to return your vehicle to standard at a later date. Once we have the full back up we can then adjust various parameters (torque limiters, boost tables, ignition timing, fueling etc). The new map file is then written back into your vehicle’s ECU and is checked to ensure it runs in perfect harmony as intended.
Benefits of ECU Remapping Include:
- Increased vehicle power
- Easier overtaking
- Smoother driveability
- Increased MPG (saving you money on fuel)
- Improved throttle response
- Improved towing abilities
- and more!
What Is ECU Remapping?
Most vehicles since the late 90’s have now got an Engine Control Unit (ECU for short). The ECU’s purpose is to control how the engine runs, and make sure everything happens at the right time and make sure everything is running optimum. It does this by reading values from a multitude of sensors in the engine bay(Air flow meter, Manifold pressure sensor etc), looking up the data using multidimensional tables inside the ECU then adjusting the engine components (Turbo pressure, Injectors, Ignition timing etc) accordingly. When Remapping we look at these tables used to control the engine and we advance them. This means the vehicle creates more power and will generate better fuel economy.
Generic / Flash mapping
This is simple to explain, and the name gives it away. Generic means not relating to anything specific. More like a one size fits all. This term came about after tuning companies spent a long time tuning one vehicle and once finished, they would then sell this file repeatedly to be applied to lots of vehicles. This approach might not sound that bad right? Wrong. Engine components will always wear differently, no two vehicles / engines are completely identical. This can be due to mileage, service schedules, how they have been treated, climate etc. The list is almost endless. An example of this, say we have 2 vehicles, one has 10,000 miles, the other has 93,000 miles. These two vehicles may have left the factory in the same condition, but they will have had completely different lives.
The approach to custom remapping a vehicle is completely different. Again, with custom the name says a lot. If you had an extension on your house, it would be custom built. They could never use plans from another build on yours. It would never work. This is a similar story. With a custom remap a file is usually built for your vehicle, then once applied as many parameters as possible are data logged from the engine with specialist diagnostic tools to analyse exactly how the engine is responding. Once this data is collected, the tuning file is adjusted to fix the discrepancies between what the file has requested and what the vehicle is doing. The tuning file is then applied back to the vehicle and further testing is carried out. This process runs in a full circle until the vehicle is correctly setup. This process can take 30 minutes up to a full day or even 2.
How Long Does ECU Remapping Take?
Our tuning service usually takes around 2 hours to complete on average. This is based on the specific vehicle as some can take around 1-2 minutes to read and write the ECU software, whereas others can take up to 1 hour just to read. This includes the pre-tuning health check, reading your vehicles ECU software, creating your new software, writing the new software to the vehicle and then data logging to confirm your vehicle is running healthy. Any further map adjustments may delay this further if they are needed. We understand you may need to work to a tight deadline so please ask if you need a specific time and our team will do our best to give you a more accurate time frame.
