WHAT DO YOU ACTUALLY MODIFY IN MY VEHICLE?

We do not change any hardware in your vehicle, we just modify the operating parameters in the ECU’s program or ‘map’. In many cases the map stored on the ECU’s processor can be accessed via the on-board diagnostics port (OBD) in the vehicle, normally found under the dashboard. In some newer models the ECU will have to be removed from the vehicle and the casing opened, our technicians will then use specialist tools to read the original map straight from the processing chip.

The technician will then upload the original map to our map writing team who will adjust the parameters to maximise the performance, fuel economy or a clever blend of both. Depending on the vehicle and ECU type the chip tuning process can take under an hour and if at any time you wish to return your vehicles ECU to its original default settings, this can be done easily and free of charge as we always keep a copy of the original software as a backup.

ECU REMAPPING BENEFITS FOR TURBOCHARGED PETROL ENGINES

Turbocharged petrol engines have always been regarded as the sports flagship engine for good reason. They boast far higher power & torque figures than a non-turbocharged power-plant with similar displacement and are usually fitted to the manufacturer’s flagship models. They are also ideal candidates for programming as the ECU also controls the wastegate (turbo boost pressure control).

After your ECU upgrade to your turbocharged petrol engine, you will enjoy:

  • Increased horsepower
  • Increased torque
  • Better throttle response
  • Smoother power delivery
  • Safer overtaking

ECU REMAPPING BENEFITS FOR TURBOCHARGED DIESEL ENGINES

Many see the modern crop of Turbocharged diesels as the future of road car’s chip tuning. Even in North America, a nation famed for its love of the petrol engine is starting to come around to the benefits of turbo diesel passenger cars in particular. These engines offer fantastic potential for reliable low cost tuning without removing any of the appeal of buying and running a turbo diesel powered vehicle, such as economy, reliability and longevity.

After your ECU upgrade to your turbocharged diesel engine, you will enjoy:

  • Every vehicle we do is Custom Remapped, we dont use generic downloaded maps
  • Increased horsepower
  • Increased torque
  • Better throttle response
  • Smoother power delivery
  • Improved fuel economy
  • Safer overtaking

BENEFITS OF ECU REMAPPING/PROGRAMMING

ECU programming will not only improve the engines power and torque figures it will also sharpen the throttle response and widen the power-band. This will make the power delivery a lot more linear, which in turn will make the vehicle feel a lot livelier to drive and the engine more flexible. Frequently, the vehicles power output is restricted by the manufacturer for no other reason than to ensure that the vehicle fits into a class to suit fleet buyers. As a driving enthusiast, you do not need or want such restrictions placed upon your vehicles ECU and its performance therefore you can benefit from the hidden power and torque locked away within your engine management system.

The other main benefit of remapping will be a reduction in fuel consumption. With the extra torque especially at the bottom of the rev range you will see a fuel saving as it will require less throttle input to maintain motorway speeds, you can drive in a higher gear at a slower speed as well as helping significantly when fully laden, towing or on gradients and even in start stop traffic.

WHAT IS ECU REMAPPING/PROGRAMMING?

When a manufacturer develops a new car they have to take into consideration all of the conditions it may be subjected to in all of the regions in which they intend to sell this model. This means instead of just optimising the ECU’s program or ‘map’ to deliver the best performance or the most fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions. These could include sub-standard fuels, extremes in temperature and altitude, differing emission laws and even the possibility that vehicle may not be serviced on a regular basis and in accordance with the manufacturers recommended instructions.

ECU remapping is taking a read from the ECU’s processing chip of the vehicles standard compromised map and adjusting various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to release the true performance from the engine. It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the originalprogramming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine; unleashing more power and in many cases reduce fuel consumption too.

WHAT IS ECU (ENGINE CONTROL UNIT)?

All modern cars and vans on the road today have an ECU (ENGINE CONTROL UNIT). This Engine Control Unit can almost be described as the vehicles ‘brain’ and contains a small processor that takes information from various sensors throughout the engine. It analyses information such as the engine temperature, accelerator pedal angle, oxygen content in the burnt exhaust gases as well as many more parameters. Using the information from these sensors it can then add the right quantity of fuel, at just the right time to provide a good mix of fuel economy, performance and emission control when pulling away, overtaking, pottering down the road or zooming down the motorway.

WHAT ELSE SHOULD I BE AWARE OF?

  • It is often said that you should “go for a blast” down the motorway to clear the DPF. Please note this is only partially true. If the DPF is blocked beyond the capacity for regeneration or blocked due to Ash residue, you will do more harm to your engine.
  • There are many DPF cleaning additives available promising a magic cure for DPF. We have yet to find one that will clear a blocked filter and will certainly not clear an Ash blocked filter. Some products can however be useful in keeping a functional DPF in good health.
  • DPF units are closely linked with other emissions components, if these parts do not function properly they can help to block the DPF, similarly a blocked DPF can damage these components due to excess back pressure.
  • DPF units are located close to the Turbo, if the turbo is leaking oil it can help to block the DPF, similarly a blocked DPF can damage the turbo due to excess back pressure.
  • Some PSA engines fitted to Peugeot, Renault, Ford, Volvo and Nissan have an on board Fuel Additive System connected to the DPF to help regeneration. It is important to maintain this system and keep it topped up with the additive (only available from main dealers approx £130 per tank) if not it will block the DPF. In our experience this is often neglected, even by main dealers due to the cost. If you have the DPF removed this function as it is no longer required and can be disabled.
  • Some vehicles have a dedicated DPF or Emissions or Anti-Pollution warning light which is great, however many will just have an Engine light on. It is important to check by diagnostics why the light is on and not advisable to simply get the light turned off without investigation.
  • DPF work is complex and should only be carried out by experienced professionals with the correct specialist equipment. All work on a DPF has to be completed with the appropriate recalibration or reset on the vehicle ECU. It is not possible to simply delete the DPF electronically or just remove the DPF unit without work on the ECU.
  • It is our experience that many garages including main dealers are not knowledgeable in DPF and related issues. Our dealers often see customers after they have spent a lot of money on the wrong fixes as the DPF fault was not correctly diagnosed.
  • Diesel Particulate Filters were designed with good intent to reduce particulate emissions and offer a better environment. In theory a DPF would trap soot in urban areas and then regenerate on the open road, unfortunately this does not always work well leading to expensive repairs.
  • The fact that DPF units are made with expensive minerals like Platinum, that excess fuel is needed for the regeneration process and that ultimately the accumulated soot and ash has to go somewhere… back into the environment which many now question the overall environmental value of the entire life cycle.

Better Throttle Response

WHAT ARE MY OPTIONS?

If your DPF warning light or Anti-Pollution warning is on, please do not ignore it (typical dash warning symbols below). Get professional advice, consider your options carefully and attend to the problem. Leaving it will ultimately cost you much more in additional repair bills and it can be dangerous.

By the time your DPF warning lights are visible your DPF will already be significantly blocked. Forced regeneration by a garage or a “blast down the motorway” is not likely to cure the problem, these only work as preventative maintenance. So at this stage realistically you have the following options:-

DPF Regeneration – Quantum dealers can offer a regeneration service

DPF Replacement – Quantum dealers can replace the DPF, normally at a fraction of the main dealer cost.

DPF Cleaning – Many Quantum dealers offer a DPF cleaning service

DPF Recalibration – If you have had your DPF core removed, your Quantum dealer may be able to recalibrate your vehicles ECU to stop your engine going into limp-home mode and clear the DPF warning light. Consumers must be aware of the legal implications (as above) of this being carried out.

DPF removal is legal in certain countries and when used for off-road or motorsport – if in any doubt please take advice.

The ideal DPF solution for you depends on your circumstances e.g. type & condition of your vehicle, your usage, your future plans i.e. whether you intend to keep or sell the vehicle etc and your budget.
