The DPT module, vehicle specific wiring loom, fitting Instructions & warranty form.

Saving fuel is the key reason for buying a DPT module. Increased torque means driving will require fewer gear changes and result in lower fuel consumption, typically a 5-10% improvement can be expected. Coupled with a high flow air filter and a fuel treatment the benefit will be enhanced further. In some cases the DPT module has been programmed to provide up to 16% savings in fuel, making it a potentially major cost saving option.

We have been successful in attracting fleet business, where high mileage vehicles have very quick payback on the cost of the DPT module and savings can be quite significant over the life of the vehicle. In some cases the DPT module can then be transferred to subsequent vehicles.

The VM has many different factors to consider when preparing vehicles and engine variants to suit a number of international markets and other global factors; Climate - of destination countries can vary between –40c to +50c, climate conditions can greatly affect performance and this has to be taken into account. Fuel quality - manufacturers have no control over fuel quality in the country where the vehicle is used, they have to make allowances to cater for variations. Servicing – Not everyone services their vehicle on a regular basis, so manufacturers have to allow for the operation of poorly serviced vehicles. *For the best MPG performance diesel vehicles should be serviced regularly* Development costs – Most manufacturers develop one engine and de tune it to offer a wide range of power output options, to save massive amounts of money in the development stage.
Marketing – Many manufacturers refresh the flagging sales of a particular model, by offering a NEW higher-powered model, or increased MPG model, in many cases this is achieved by no more than reprogramming the engine management system.

Your vehicle for example may have the power output reduced to comply with a specific requirement in one of the VMs key markets. Thus you purchase a vehicle capable of achieving far more BHP and Torque without ANY compromise to the integrity of the engine. Also VMs fit the same engines into various different vehicles and do not specifically tune for each one, the DPT module achieves optimum tuning for your engine / vehicle combination. Most other European countries have stricter emission controls than the UK and tune their engines accordingly. Better performance in terms of MPG, BHP & Torque are achievable if the DPT module is fitted.

Certain manufacturers do indeed offer upgrades as an optional extra e.g. BMW offer their "Efficient Dynamics" package which again increases BHP, Torque and improves MPG with reduced CO2. But none of these bear favourable as a price comparison to the DPT module and are not portable in the same way as a DPT module is. These examples do clearly demonstrate though that the VMs are comfortable with the concept of increasing the power of their engines. As of course are Mercedes Benz who in the Netherlands have authorised many of their official dealer networks to fit the DPT modules.

Because of the very high compression ratio of diesel engines, typically over 20:1, the cylinders contain more air than is needed for normal operating conditions. By slightly increasing the pressure at which the fuel is injected we make better use of ALL the air available which dramatically increases both the power and torque. As a consequence of this the engine is operating more efficiently, so less throttle is required for any given set of driving conditions, hence the engine uses less fuel and is both more economical and consequently emits less CO2.

The modern diesel engine relies upon many sensors within the engine control system to determine how the engine performs and alters its parameters to suit certain conditions, such as; idle, full throttle, heavy load. These sensor signals are all processed many thousands of times a second by the engine's on board computer (ECU) which then makes alterations to keep it running at full efficiency.
The DPT module intercepts some of these signals, sending the ECU appropriately adjusted feedback signals, which ultimately alters the fuel mapping of the engine, providing increased efficiency.

No, the unit simply enables your engine to develop more power & torque, which are contained within the vehicle manufacturers tolerance levels so there is absolutely no possibility of damaging your engine. Think of DPT as improving engine "efficiency".

No the DPT connects between the original ECU and the injection system of your car. The DPT intercepts the data coming from the original unit, re-calculates and optimises the data before sending the modified parameters to the pump.
This is why so many opt for DPT instead of a ReMap or a Piggy-Back chip neither of which can be transferred over to another vehicle or sold on by the user.

The DPT module can simply be unplugged at any point in time and your vehicle will immediately return to its standard settings & performance.

No, the unit does not modify your vehicle in any way.

The unit comes with a technical helpline number. Alternatively you can phone us on 02084073413 or 07956585787 or email us at info@mcautos.co.uk.

You will need to record your current fuel consumption, you can measure this by recording the mileage you are able to cover on a set amount of fuel & then repeat this procedure with the DPT module fitted (bearing in mind that the journey type e.g. motorway / city driving as well as your driving style should be the same for the result to be accurate) Whilst you will immediately feel the additional torque when driving, the only way to quantify the BHP is to have your vehicle put on a rolling road (dynamometer test).

Two years if you purchase for DIY fit.
Three years if you have the unit fitted by an official installer.
Each unit has a unique serial number and a warranty form, which should be returned to the address on the card to register the warranty. Whilst the warranty is 2 or 3 years there is no reason why you should not achieve many more than this and your unit can be transferred to your next vehicle, if has the same type of diesel engine.

Vehicle manufacturers cannot invalidate a warranty for having a DPT module fitted. We strictly tune within the VMs vehicle parameters. In the unlikely event that DPT causes any problems which the VM prove to be due to DPT and will not cover under warranty the manufacturers have an insurance backed warranty with up to £2 million worth of cover to protect you.
Fitting the DPT module is not an engine modification. It is a retrofit that can be switched off or removed, it does not compromise the integrity of the vehicle. Your ECU is not being re-mapped like many other upgrade options which change the ECU software or put a piggy back chip on the actual ECU.

An additive used periodically cleans and lubricates the fuel system, particularly the injectors improving performance and fuel consumption.

We always recommend you advise your insurer of any change in your vehicle or personal driving circumstances. DPT is now a recognised product with NIG, Norwich Union and Zurich Insurance, some of the worlds largest insurers.
