Mercedes Benz CL Class Performance Tune


* Required Fields



Mercedes set out to build ‘the best luxury coupe in the world’ ... We set out to add serious power and torque to the CL and make improvements to its response without compromising on refinement. Book yours in now to see experience how epic the CL becomes.

Select your CL Class from the drop-down box to find out how much power and torque can be gained on the version you own.

Why can Power and Torque be gained from tuning my car?

ECU software is “optimised” to meet various goals that the car manufacturer has. These are not all goals that align with what you would like from your vehicle. The tune that your car was sold with might deliberately detune the engine so it produces less power and torque than identical engines sold as different models, car manufacturers do this so they can charge a premium for vehicles that are higher in the range. In this case development costs for the car manufacturer are also reduced because they are able to capitalize on producing much higher volumes of essentially one engine running a number of different tunes across different models. By running a tune that takes full advantage of an engines real potential it is most often possible to make significant performance gains The software will also be optimised to meet emissions standards, i.e. optimised over a very specific drive cycle, unfortunately, this does not represent real world driving well, when retuning a vehicle this is typically recognised and the tune is optimised for real world driving, typically emissions are not drastically different under real world conditions e.g. flat spots or creases in maps that are there to allow drive cycle emissions to be improved can be calibrated out. This will typically improve driveability, reduce fuel consumption and may increase available power and torque.

Will increasing Power and Torque increase fuel consumption?

Generally not, we are able to tailor tunes to your requirements and will in the process of tuning your car ask you about your driving style and how important maximum power, torque and economy are to you. We will create a tune that is optimised to your preferences.

Are there any risks involved in tuning my car?

Yes, but we will work rigorously to minimise the risks, what we do is vehicle specific but in general it will include the following: Particularly where pressure will be increased we will check the integrity of charge pipes and look for things such as damaged or bent clips that could cause fittings to come off when pressurised. We will check for engine related problems such as misfires and timing problems this could be in various ways such as using diagnostics tools or physically inspecting coil packs or spark plugs. We will check the condition of the battery and use a very sophisticated high current (up to 100A continuous) power supply to ensure the battery voltage is stable while the vehicle is being reprogrammed.

Why choose Auto Upgardes?

Professionalism: You will be engaging professionals that are dedicated and passionate about obtaining the performance you want from your car.
Expertise and Experience: We have 20 years of experience gathered in the engineering development centres, proving grounds, test and race tracks of the world.
Education: The engineer tuning your car will have Masters Degree level education in a relevant field (i.e. Automotive Calibration and control).

Once you place your order with us will will give you a phone call to discuss your requirements and logistics of the tuning process.

Once you are happy with the process we will make an appointment(s) to retune your vehicle.

We will work rigorously to make sure every aspect of the process is professionally done, the work required is vehicle specific but in general it will include the following:
- Checking the integrity of charge pipes and look for things such as damaged or bent clips that could cause fittings to come off when pressurised.
- Checking for engine related problems such as misfires and timing problems.
- Checking the condition of the battery. Any problems found will be discussed with you and addressed as required.
- A new tune will be created that matches your requirements.
- The vehicles ECU(s) will be reprogrammed under very controlled conditions.
- Any ancillary steps such as relarning of DSC parameters etc will be conducted.
- All files will be archived in case they are needed again in future.
