ASNU are world leaders in Injector Diagnostics, a programme that ASNU owner Phil Ellisdon created to enable technicians working in the aftermarket service workshops to test and service gasoline injectors as part of the vehicles diagnostic test and repair procedure. This programme has been successfully adopted by a number of leading colleges and organisations around the world, most notably being Robert Bosch, for use in their fuel injection diagnostic service centres and training schools. Due to its unique design, ASNU have been able to stay ahead of developments in fuel injectors and injection systems and the need to accurately examine the injectors performance without changing the ASNU from its original design. ASNU have over 30 years experience of injectors from all the various injector manufacturers from around the world. ASNU are represented in over 60 different countries with thousands of injectors being tested and serviced in aftermarket and Motorsport world wide, a programme and experience unrivalled by anyone, anywhere in the world.
