Can installing a ProMotech power module damage the engine?

Most engine manufacturers throughout the world today build their automobile engines as multipurpose engines. A standard engine, build with a high margin of safety and durability, is then used as the base for several different models and builds, often with different power outputs. This helps the manufactures tailor their engines to different countries’ tax and insurance policies. By fine-tuning original engine signals we are able to fine-tune engine performance. Nothing spells engine wear like cold starts followed by full power outtake, in combination with lack of maintenance and service. Higher performance also means more power to be used improperly.

I just bought a brand new Opel and would like a little more power. Because I would like to be able to quickly revert to original performance I am considering installing a power module instead of chipping the car. Why should I choose a ProMotech power module?

Your new car has a sophisticated fuel injection system that demands high quality signals from a power module. To be able to fully tap into the potential power increase the power module needs to utilize a model specific deviation curve. This in turn requires a digital power module using a stage less operating map and task specific processors. Most likely the car has a particle filter that may be damaged by an increase in power outtake obtained by only increasing the amount of fuel injected into the system. ProMotech’s CR5 module has a unique 2 channel function. This gives us the opportunity to connect to sets of wires to the engine enabling us to introduce more air into the combustion process. This is important for effective cooling. To keep from having to pull wirers into the cabin the CR5 module’s circuit board is completely sealed in the moulded housing and all the connectors are of automotive quality. Modules can be easily mounted in the engine compartment without fear of damage from corrosion or damp conditions. The moulded housing also offers a high degree of stability to the circuits keeping them impervious to vibration.

Why is it not possible to make adjustments to the CR5 module?

The CR5 module is the result of our latest dynamic digital technology. This basically means that we supply each car model with its own specific software, rather than more or less standard software that has to be “adjusted” to fit a particular model of car. An adjustment screw only gives the ability to adjust one axis in one direction. Our software is completely stage less, and without axes. If we were to “convert” to a traditional digital solution, we would need at least 8 adjustment screws. In addition most cars would lose out on potential power gain or in certain situations start to smoke because of too much fuel being introduced into the system.

What will fuel consumption be like after installing a power module?

It is difficult to give a conclusive answer to this question since a variety of diverse factors like driving style and conditions, type and model of vehicle, and the vehicle’s general condition come in to play. As a general rule of thumb one can say that the more underpowered the vehicle is, the greater the fuel savings, because the engine experiences greater “relief”.

I have a used ProMotech module that used to be installed on an engine similar to the engine in my vehicle. Could I install the power module in my vehicle?

This is a very common question. NEVER install a ProMotech power module with an item number not intended for your specific vehicle without first consulting ProMotech! All ProMotech’s power modules consist of 3 parts specifically engineered to work with a particular type and model of engine.

  • Wiring harness
  • Hardware
  • Software

Even though the wiring harness may fit your engine, the module may not have the required functions or the software suitable for your vehicle. The software must among other things account for:

  • Power and torque output
  • Type and generation of fuel injection system
  • Type of particle filter, when installed
  • Type of gearbox
  • Vehicle weight and aerodynamics
  • Where the vehicle was originally sold

I believe my car’s consumption has gone up after I installed the 3600 module. Could this be?

What is your style of driving like? Do you drive as carefully as you used to, or has your foot become heavy on the accelerator? If you still believe the consumption to have gone up for driving on motorways, the module is likely set to “rich”. Use the adjustment screw to set it to a “leaner” setting by turning the screw anticlockwise. Turn the screw a ¼ turn at a time until you notice a reduction in power.

Shortly after installing my ProMotech module 3718 a yellow was lit on the instrument panel. What is the problem?

Most likely the engine is getting too much fuel. Select a less aggressive setting on the power module and the engine warning light should reset. Also check the air filter, as it may need to be cleaned or replaced.

I just installed a ProMotech power module in my 1996 Audi A6. There is no noticeable difference in power output, and the car smokes.

Smoke is a sign of incomplete combustion. The cause may be one or more worn components in the fuel system, but most often the smoke is caused by the engine “running rich”. Basically there is not enough air the system to burn the extra diesel, and thereby produce the extra power we are seeking. Without the power module installed the engine was probably on the verge of “running rich”, and the extra fuel introduced by the power module is causing the smoke.

Assuming the problem is a lack of air there may be several causes. A 10 year old car often has quite a few kilometres on it and turbo may be worn and no longer capable of delivering a sufficient amount of air. Other sources are leaks around the turbo breather hose, blocked air filter or a faulty pressure regulator.

Another source of problems entirely lies within the Engine Control Unit (ECU). A previous owner may already have “chipped” the car.
