How it Works
The DPChip is designed to simply and safely modify the engines fuel injection parameters to increase performance. Once you've fitted a DPChip you'll begin to experience the true optimum performance of your engine. The DPChip digitally alters both fuel volume and fuel timing to optimise the entire engine map. Be wary of European imitations which only alter fuel volume without fuel timing simultaneously. These European systems are also not set up for Australia's conditions. Operating temperatures in cooler climates mean they are not sut up correctly for use in Australia's hot conditions. Australian diesel is of a different quality to European diesel so please consider the benefits of a prodcut like the DPChip which is set up specifically for Australian conditions. Unlike some other systems on the market, DPChip has been extensively tested in 'REAL WORLD' conditions, not just in a controlled environment such as a dyno room, and thanks to the help of the leading 4WD diesel experts in Australia the DPChip has the advantage as being truly tested tough! Our ongoing development program ensures we keep up to date with the latest engine management and injection systems.
To increase power in a diesel, an easy and cheap way out is just to increase fuel loads but this is very inefficient and while it will result in power increases they will not be clean increases (it often creates lots of smoke
- unburnt fuel) and does not allow any possibility or improved fuel consumption. Basically a very inefficient and nasty way to tune a diesel.
The DPChip changes both fuel and timing.
Let’s just first look at how CRD, like the D4D Prado, works. There are many areas of an injectors cycle but let’s point out the main ones.
• Start of main injection (basically the timing point/start ofcombustion)
• The volume of fuel volume which is influenced but not limited to therail pressure
• Closing point of injector which mainly influences emissions if it isvaried.
The DPChip interfaces on CRD engines into an engine plug with signals that have the ability if manipulated correctly, to alter these points. It’s the secret ‘herbs and spices’ of the DPChip that many other simpler devices would love to know but that’s our intellectual property and we like to keep it that way so we can't discuss the technicalities in too much detail. We have had many manufactures test and try and work out how but can’t decipher the ‘code’…..yet it works and leaves them wondering.
What we can tell you is that that when the DPChip is interfaced, depending on certain Load and RPM, it can manipulate timing up to 4 degrees advanced (generally speaking) and fuel volume/pressure by up to 600PSI, depending on vehicle, in relation to RPM and Load. It can also have a small impact of a few degrees on closing points. Now in the BIG picture of 25,000PSI its not much…….but…..it doesn’t take much to alter fuel volume anyway.
Two simple methods we distance ourselves from are:
• ‘just rail pressure’ increasers which may raise rail pressure by 3,000 to 4,000PSI above standard to get reasonable fuel volume gains. These also plug into the same plug we do but don’t work like the DPChip does hence the pressure they get things to….ouch!
• ‘injector plug in’ controllers (they are plugged into each injector) which can only just add additional ‘tail fuel’ by extending the opening time of the injector. These cannot alter timing (opening point).
In the end we offer warranties and support like no other because we now our product works and we back it with such support.
Installation
The DPChip is designed for quick and easy installation. Most DPChips are a simple plug and play installation using original adapter plugs. It is absolutely impossible to damage your vehicles electronics or ECU before, during or after installation because the DPChip is 'downstream' of the ECU and remains in a 'slave' position. Your existing engine computer remains in 'master' control of all engine operational safety features at all times. DPChip cannot make any changes until the ECU has told it everything is safe and 'good to go'. There is no way to short out or damage your ECU or electrical system during installation of a wire-in DPChip. We have designed the DPChip with engine safety as the primary concern at all times. It is simply impossible to damage something even if you connect up the wrong wires during a wire-in DPChip installation. All that would happen in that case is the DPChip will not function. Every DPChip comes with detailed illustrated fitting instructions so it can be easily self installed. Alternately, any auto electrician or one of our distributors could easily install the DPChip in around 10 - 40 minutes depending on vehicle type.
DPChip is compact and lightweight, the smallest being only 10cm across, the largest being 13.5cm. The DPChip is designed to be fitted easily and discreetly and most models come complete with matching or original plugs and an original style harness resulting in a true 'Plug&Play' device. One particular advantage the DPChip has is that it is installed 'down stream' of the ECU. This means that the electronic changes that it is making are downstream of the vehicles factory ECU, between the ECU and the injection pump in most instances. This helps prevent conflicts with the factory ECU signals. Most other tuning devices on the market are 'upstream' and interfer with the vehicles ECU often causing problems with engine warning lights coming on unexpectedly. With DPChip there are no such problems, your ECU handles all operational safety and warning systems as per normal. Generally a DPChip can be installed in around 30-60 minutes with the simplest being a matter of a few minutes. All are designed to be easily installed by people of average mechanical capability, or if you prefer, you can have it professionally installed at one of our distributors. If you wish to remove the DPChip, for either transferring onto another vehicle or for any other reason, it is just as easy.

Adjustable Tuning
Your DPChip will come already pre-adjusted to suit your make and model of engine and no further adjustment is required. If however, you decide to enhance your vehicle further, perhaps by adding larger intercoolers, larger exhausts, larger tyres etc. you can easily adjust the DPChip to match the new modification so the full potential can be reached. With fixed map boxes and chips this is not possible and a new chip or box would be required.
Adjustment is simple and allows you varying degrees of control over just how much power you want. The 2 Series DPChips use a small screw upon the body to optimize a number of parameters while the 3 Series DPChips have 10 pre-programmed power settings which the user can adjust for more power.
10 Position Selector
The different settings are really more of a fine tuning and to account for slight variations between individual vehicles. If the vehicle is a factory standard vehicle then just leave it set on 5. If it is modified or you fit a larger intercooler or exhaust then you can adjust upwards to take advantage of this but there is really no need.
We flash the chip inside the module with the rotary dial set on 5. This is an arbitrary setting but if we flashed it with the dial set on 9 you could only adjust downwards. Each notch up or down from 5 moves the whole programming inside the chip up or down a few percent.
Instructions for adjustment come with the chip. Feel free to 'play' and find what is best for your style of driving and vehicle. We don't recommend going above 7 or 8 on a factory standard vehicle. You can't damage the vehicle at all. Each vehicle will be different, even if produced in the same factory on the same day. We have seen this with two of the same vehicles, one having a 'best' setting of 6 and the other 8. These were same month and year model of the same vehicle type.
The 3 Series DPChips also have adjustable tuning via USB connection. These are able to be 'laptop tuned'.
Laptop tuning the DPChip

This is a form of tune that can do considerably more than the manual adjustment. Once the DPChip is installed you can actually sit in the driver's seat and the DPChip can be re-programmed as you drive along. As well as overall power being able to be increased, the power band can be moved up or down the rev range depending on your requirements and the power delivered can be adjusted from smooth to aggressive. There is really no need for laptop tuning on a factory standard vehicle. This advanced tuning would only be required on a very heavily modified vehicle. The manual user adjustment provides more than enough tuning range.
The Result
An immediate increase in both torque and power is obvious when you first fit your DPChip. You will appreciate the improved throttle response and the increase in low and mid range torque. If you're towing a caravan or trailer or have some other heavy load you'll notice advantage the extra power provides. Overall driveability improves and with less need for gear changing your driving will be smoother and more efficient. This improved effieciency often results in fuel savings. In fact, in tests and trials we have performed, as well as reports from satisfied customers, benefits of approximately 10% better fuel economy have been achieved. This obviously varies from vehicle to vehicle and application. If you drive normally and you take full advantage of the power increase you'll realise the cost savings available through improved economy and performance. Around 1 to 2 ltres per hundred better consumption can be achieved. You do the maths!
