Summary of change:
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: * fire injectors at a preset pulswidth * set a number or time of injections * check flow a minute * check spray pattern * cleaning the injectors with solvent instead of fuel * Measure Ramp-up time. * Measure Ramp-down time. * Measure flow decline with lowering voltage. Searching the internet for a simple PIC controller i found the website of [http://www.romanblack.com/shift1.htm 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.
