Engine Tune and Oscilloscopes

Piano tuning is an art:

Engine tuning is a science. 

Modern cars can have 150 or more on board computers. Each running multiple networks. Each computer  has  sensors feeding information to it. This information is processed by the computer and fed to the main processing computer and to other networks 

The warning lights on the dashboard can be triggered by many varying problems. 

Blocked throttle body before and after ultra sonic cleaning

Seeing  a message on the dashboard like “Your left headlight needs attention”, leads drivers to believe that by simply plugging a computer tool into the car’s on board computer it will show the technician exactly what any problem is. 

Nothing could be further from the truth.

Vehicle manufacturers used proprietary error messages. These suggest to the technician an area or condition that requires further investigation.

Engine tune

Tracing defects in car engine management

Reading the live data in conjunction with the error messages  is only the start of the inspection process.

Sophisticated diagnostic work requires the aid of state of the art oscilloscopes coupled to specialised Computer software. 

The patterns that are presented on the oscilloscope screen give the technician the ability to see, nanosecond by nanosecond, the simultaneous interaction of multiple mechanical and electronic signals simultaneously in real time. 

It is only the highly trained technician who has an in depth understanding of the science of the modern engine that can analyse and identify the problem.

We have the equipment and knowledge to check that your car’s management systems are performing to the best of their ability.

  • More engines have been destroyed by oil filters than any other filter on the car
  • Due to fuel combustion contaminants are deposited in the engine oil.
  • As a result the oil Is thicker and does not flow as easily through the narrow channels leading from the sump to the pistons and bearings.
  • In addition oil is consumed during the normal operation of the engine. This means that there is less oil in the sump for circulation through the engine.
  • The function of the oil filter is as the name suggests, to trap the burnt carbon particles in the oil and not allow them the to return to the parts in the engine that require constant lubrication.
  • As more and more contaminants are trapped the flow of oil flow through the oil filter is impeded.
  • The compound effect of the thickened oil due to burn off and contaminant pickup eventually blocks the filter medium completely.
  • The filter housing has a release valve which opens and sends the unfiltered oil back into the engine and this is the beginning of the end for your engine.
