EFI Service/Diagnostics

This workshop is equipped with the latest "Electrajet" EFI Computer Diagnostic equipment to provide you with all the service and expertise of a specialist EFI service centre. We can accurately diagnose and repair any EFI problem in order to restore the power and economy to your vehicle.

Petrol Fuel Injector Cleaning

Injector Cleaning2.jpg As part of our all-round EFI Diagnostic Service, we offer top quality EFI fuel injector testing and cleaning. This allows us to diagnose with absolute certainty such things as leaky injectors, poor spray patterns, electronically damaged injectors, mechanically damaged injectors, weak return springs, annular bore differences, solenoid winding differences and much more. Injectors need to be cleaned in order to operate properly. Injectors which are contaminated at the seat will drip or spray when the computer thinks they are closed.

Our specialised injector cleaning equipment can pulse the injectors up to 9900 pulses per minute and that is the range necessary to carry out tests on the latest engines in the market today. Our injector cleaning service uses ultra-sonic cleaning in a mild detergent type cleaning fluid that is both non-toxic and environmentaly sound.

Why clean injectors?

Every time you stop a hot engine a small amount of residue adds to the already present build up on your vehicle's injectors. The more frequent the stops, the more rapidly the build up accumulates. This accumulation eventually reduces the flow of fuel through the injector and disrupts its spray pattern, causing the engine to run lean. This can cause a number of problems, although the most common is driveability problems such as flat spots and hesitations.

Most fuels do contain detergents to clean the fuel system and injectors. However there is a limit to what they can achieve and it is sometimes necessary to use a more severe cleaner to remove long-term accumulations.

Fuel Injectors are cleaned using ultrasonic equipment to ensure all residue and contiminants are removed.

Things you need to know...

Injectors need to be clean in order to operate properly. Injectors which are contaminated at the seat will drip or spray when the computer thinks they are closed.
There are over 30 different configurations of electronic injectors on the market today.
Some engines today can easily achieve 7000 to 7500 RPM and EFI test equipment must have the rpm range necessary to locate difficult problems.
Some inferior EFI equipment will actually attack and destroy alloy components found in modern injectors.
Carbon deposits in the injector port only .5 microns thick can reduce an injector’s flow by up to 25% causing rough idle, poor acceleration and poor fuel economy.

CODA Engine Analysis

CODA Engine Analysis is the latest technology in engine analysis systems. Faults such as ignition misfire, blocked filters, and poor fuel economy can be tested by a simple measure of your vehicle's exhaust gas content. Digital and graphic text messages are displayed to monitor engine mechanical condition, ignition performance as well as ECU, oxygen sensor, air mass measurement, throttle position sensor outputs on all EFI engines, or carburettored engines, of any make or model. This world-class diagnostic technology allows the service technician to quickly identify problem areas. Computer diagnosis of complex faults is often the only way determine repairs required on late model vehicles. Make an appointment for a complete engine analysis.
