Chip Tuning is now OBD
Chip tuning is the original definition of what modern day ECU Remapping has become. Chip tuning requires the removal of the Eprom chip from the ECU circuit board and the software is programmed to the chip on the bench. Alterations to the the software inside the chip is what is referred to as remapping, i.e. altering the standard software within a chip. Chip tuning has become less and less prevalent in the market place as OBD remapping has taken place enabling remapping to be done via the OBD port. They are essentially exactly the same thing, only OBD port remapping is less intrusive and requires no removal or opening of the ECU. As electronics have advanced further, the latest generation of ECU’s have what is referred to as a locked TriCore processor. This in basic terms has removed the ability to flash software via the OBD port and the only method available is to open the ECU and remap via direct connection. It is much less invasive than chip tuning as you do not remove the Eprom.
We work on all ages of ECU from the early EDC's requiring chip tuning right the way through to modern MEDC17 locked tricore processor ECU's with tuner protection.
All of our remaps are developed and logged to ensure engine parameters are accurately monitored for the following:
Air Fuel Ratios (AFR’s)
It is important to ensure optimum AFR is achieved in order to ensure that stoichiometric mixture. This in basic terms means that the engine isn’t running lean or rich fuel mixture. This is also important in ensuring that your engine is MOT compliant.
It is important that correct boost pressure control is achieved to ensure that no spikes or dips occur to ensure maintained life of the turbo charger. A spike in the boost delivery can cause over-boosting which pressurises the compressor to a level beyond its tolerance.
Exhaust Gas Temperatures (EGT)
When increasing the fuelling and boost pressures of an engine it naturally increases the EGT. It is important to log the EGT of an engine as there is a crucial limit which shouldn’t be surpassed to ensure maintained longevity. This is a good tool in monitoring the efficiency of uprated intercoolers etc.
Injector Duty Cycles (IDC)
This is crucial to know the fuelling limitation of the injector. On some modern cars we are seeing injectors with 100% IDC from standard meaning there is no room for further modification without upgrading the injectors (this is rare however). If it was a turbo application, and the boost pressure was raised, due to there being no additional fuel available, it would cause the engine to run lean and potentially melt your pistons.
As a result of fine monitoring and adjustment, we are able to provide safe and reliable tuning solutions to both customers and other tuning companies. We will not operate outside of the engines capabilities on standard components as your vehicles reliability is as important to us as it is to you.
Fleet Management Solutions
Pendulum's Fleet Management Software can recalibrate your vehicles to your requirements to enable fuel savings, RPM / speed restrictions and a reduction in C02 emissions. Therefore protecting your business assets and reducing your overall running costs.
We understand that driving styles can adversely affect your operational costs and not just in fuel, but servicing and maintaining your vehicles, not to mention lost revenue whilst the vehicles are being repaired. Our Fleet Management Solution can enforce a driving style so that maximum efficiency can be achieved and ensure your running costs are kept to a minimum.
Benefits of RPM & Maximum Speed Limiters
Prevents the driver from cruising at high speeds saving fuel.
Prevents the driver from hard driving, typically limited to 3,000rpm, saving fuel.
Increases engine longevity due to more sedate driving.
Can increase service times for variable service schedules.
Reduces overall CO2 output.
Enforced Driving Style
A Pendulum Eco Re-calibration allows fleet managers to restrict driver behaviour ensuring protection of the vehicle, improved fuel economy and a reduction in C02 emissions. Commercial driver's in high traffic areas typically spend most of the time between 3,500-4,500rpm and 80%+ throttle position. In basic it is a perfect example of hard driving.
A Pendulum Eco Re-calibrated vehicle typically spends most of the time between 1,750-2,500pm and 40-60%+ throttle position. This enfoces a light driving style saving you greatly on fuel and decreasing the cost of maintenance.
Diesel Particulate Filters (DPF)
The exhaust emissions standards for new cars have effectively required fitment of a DPF in the exhaust of diesel cars since 2009 when the 'Euro 5' standard came into force. In fact, many cars registered before 2009 will have had one fitted too in anticipation of the change in standards.
Standards aim to deliver an 80% reduction in diesel particulate (soot) emissions but as owners are finding out with great expense, the technology is not without its problems.
How do they work?
The DPF looks similar to a traditional exhaust silencer, but is mounted close to the engine. Inside is a complex honeycomb ceramic structure designed to filter the exhaust gases while minimising flow reduction (which would otherwise limit performance). By forcing the exhaust gases through the walls between the channels of the DPF, the particulate matter is deposited on the walls, so reducing the amount of air pollution. Once the DPF reaches a certain level of ‘Saturation’ it performs a regeneration cycle to burn off the particulate matter inside the filter.
There are two types of regeneration:
Active DPF Regeneration System
When the soot loading in the filter reaches a set limit (about 45%) the ECU will initiate post combustion fuel injection to increase the exhaust temperature and trigger regeneration. If the journey is a bit stop/start or you take your foot off the accelerator while the regeneration is in progress, it may not complete and the warning light will come on to show that the filter is partially blocked.
Passive DPF Regeneration System
Passive regeneration takes place automatically on motorway-type runs when the exhaust temperature is high. Because many cars don't get this sort of use car manufacturers have to design-in 'active' regeneration where the engine management computer (ECU) takes control of the process.
A car which is primarily used for motorway use will generally run at warmer temperatures and therefore produce far less particulate matter than one used in a stop/start city environment. A vehicle used on the motorway is also going to be able to regenerate more often and effectively as it is in the perfect driving environment for the regeneration process to occur.
The operation of the DPF is controlled by the ECU and requires multiple signal feeds from various sensors in order to operate effectively. The most common type of DPF runs two pressure sensors and a varying number of temperature sensors. There is differential pressure sensor mounted in the engine bay which picks up the pressure both before and after the DPF. It is the variance in pressure between these two pick-ups which allows the ECU to calculate the percentage saturation of the DPF. Once the ECU establishes the saturation level it is able to force a regeneration cycle. The progress of the cycle is monitored by the temperature sensors and takes constant feedback from the differential pressure sensor which enables to know when the burn off process is complete.
Diesel Particulate Filter Additives
Some manufacturers use additives to reduce the ignition point of the soot particles by secreting small amounts of fluid into the fuel tank which mixes with the fuel. The additive is a service item and is designed to require refilling every 75,000 miles approximately. Ignoring the warning for low additive will mean the DPF will not regenerate properly and will almost certainly require a new DPF. Certain models of vehicles however require the DPF to be changed with the additive top up which makes for expensive servicing bills.
Do They Require Maintenance?
A DPF has a design life of around 120, 000 kilometers but this can be subject to large variation depending on vehicle use and engine condition. Every time the ECU forces a regeneration cycle it burns the particulate matter down to a much smaller amount of finer soot, they don’t get completely removed from the filter. Over time, the fine soot content builds up to a point where a regeneration cycle is no longer able to be performed; at this point the filter either needs emptying or replacing.
Removing the DPF is often advised to check the opacity of the exhaust emissions which can give some indication of any potential running issues which can impact on the operation of the DPF. Issues such as leaking injectors and engines burning oil can massively reduce the life of a DPF.
Common Causes For DPF Failure
There are a multitude of reasons a DPF can fail, the most common are highlighted below:
High mileage and compacted with fine soot.
Failed sensors preventing DPF regeneration.
Lack of additive in fuel (where fitted) causing incomplete burn off.
Engine issues i.e. leaking injector, valve stem oil seals, worn piston rings.
DPF unable to regenerate due to driving conditions i.e. City centre.
Poor performance tuning.
Driving in too low of a gear on a motorway disallowing the regeneration to commence.
Diesel Particulate Filter Removal - DPF Delete
Are you having problems with your DPF?
Are you facing a large bill for your DPF replacement?
Is your DPF causing you poor fuel economy?
DPF Removal can solve your problems
We have at Pendulum unrivalled knowledge and experience in DPF Removal from modern ECU’s. Our DPF delete software will ensure that you have trouble free motoring after the DPF removal and give you piece of mind that your vehicle will not go into limp mode due to DPF regeneration ever again.
Modern turbo diesel management systems all accommodate the use of a ‘diesel particulate filter’ as it has become mandatory as part of Euro Emission controls. The problem many are finding is that any driving other than motorway use will cause the DPF to clog up and force it to regenerate. There is only so many times a DPF can regenerate before the compacted soot reaches a critical saturation level at which point DPF replacement is imminent. With the DPF not being part of an MOT emission test it is not a requirement for it to ‘function’ as a DPF. Our DPF remap in basic switches off the functionality of the DPF ensuring it never attempts to regenerate again. What is required is that the DPF filter is removed from the centre of the exhaust core ensuring all sensors are still in place and functioning. When finished, the DPF still looks to be in situ with all sensors operational just not DPF trap and no regeneration problems.
Benefits of DPF Removal
Pendulums’s DPF Removal software will ensure that your vehicle operates without the DPF being present. Most customers also benefit by having a performance remap alongside the DPF remap which provides even better gains than just the DPF Removal itself. The benefits of DPF removal are as follows:
No expensive DPF replacement costs.
No more limp modes when the vehicle decides to do a forced regeneration.
Improved MPG due to the removal of an air restriction allowing the engine to breather better.
Improved power output of the vehicle. We have tested many vehicle’s before and after DPF removal and every single one has provided a performance gain.
After DPF removal it is possible to use bio fuels as they can no longer cause issue to the DPF filter.
Is DPF Removal Legal?
Please note that we only offer DPF solutions for Off-Road Usage only. Although it is not illegal to remove a DPF filter form your vehicle, it is an offence under the Road vehicles Regulations to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. Removal of a DPF will almost invariably contravene these requirements.
DPF Removal For Most Makes & Models
Notes regarding DPF Removal
DPF’s have multiple sensors which aid its operation. These include temperatures sensors and differential pressure sensors. All of these sensors must be working in order to have the DPF removed.
2. If a car is in limp mode and the DPF is compacted requiring replacement, simple removal may not always cure the problem. The DPF failing is often a symptom of another fault, not the cause of the issue. For instance, a car may require a DPF replacement due to compaction but the cause may be leaking injectors which have caused the DPF to fail. Similarly the management light may be on and in limp mode, the DPF may be saturated requiring replacement yet after removal the car may still be in limp mode and management light in with the common cause being a faulty differential pressure sensor and the reason the DPF failed. DPF removal is a great facility and can save you thousands but sometimes there are additional parts that require replacement which only become highlighted after the DPF has been removed.
Exhaust Gas Recirculation (EGR) Delete / Bypass
The EGR valve (Exhaust Gas Recirculation) is an emission control device designed to reduce NOx emissions to help towards the ever more stringent Euro Emission Regulations. Celtic Tuning EGR Delete and EGR bypass software is designed to remove the functionality of the EGR valve to ensure it removes the running issues associated with these devices.
How do EGR Valves Work?
The EGR Valve creates a loop back from the exhaust manifold to the intake manifold to recirculate burnt gases.
The EGR valve has a solenoid which controls the valve which in turn is controlled by the ECU.
The ECU operates the solenoid by using a duty request cycle in order to open the valve and recirculate the burnt gases.
The Manifold Absolute Pressure sensor is then used to record the amount of additional gas which subsequently feeds back to the ECU as a control measure.
EGR Valve Problems
As the EGR valve is constantly working with burnt exhaust gases they naturally have high soot content. This soot in the gases causes a build-up of carbon deposits around the valve operation area which in turn causes the valve to have a tendency to stick in various positions. For full engine performance the EGR valve is closed which creates a closed loop environment for the turbo system which allows it to pressurise. A problematic EGR can create an open loop environment for the turbo as it provides a feedback straight to the intake manifold and as a result can cause boost issues along with huge reductions in power and also fuel economy!
Benefits of EGR Removal
Restored Engine Power
Cleaner emissions as faulty EGR’s create much higher soot deposits
Can prevent DPF failure as the soot is caught in the DPF trap
Can prevent EGR replacement which can cost hundreds of pounds
Having your EGR Delete software can save you money in repairs and in fuel costs. Pendulum Tuning is at the forefront of EGR Removal and EGR Bypass software and can correctly remove the functionality from the software of most ECU types. Some companies will simply turn off the codes associated with it being unplugged but this is not the correct way. The EGR valve needs properly disabling to ensure it is not trying to recirculate exhausts gases whilst still physically working in the engine.
Is EGR Removal Legal?
Please note that we only offer EGR solutions for Off-Road Usage only. Although it is not illegal to remove the EGR from your vehicle, it is an offence under the Road vehicles Regulations to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. Removal of the EGR will almost invariably contravene these requirements.
