After some problems with injectors its seems to be nice to have a simple injector tester on the bench.

The testing device should be able to:

Searching the internet for a simple PIC controller i found the website of [Roman Black]

with his shift1 project. The shift1 could be used for its timer and LCD features and having the PIC driving 1 or more LM1949 cirquits to drive the injectors.

The injectors can be holded by a bracket wich connects fuel line and a fuel sensor so measring flow at diffrent fuel pressures gives a idea of the volume the injectors can flow at lower or higher pressures. Spraying must be done in a glassy box or tube.

A long glass flowerpot for a single injector or a old fishtank for multiple injectors can be used.

To be continued.
