Fuel Injector tester
Page updated 16.09.2003
For my EFI projects I needed some sort of fuel injector tester. I found great ready project fromhttp://www.bgsoflex.com/fitester.html site. I did not have Motorola parts and programmer available so I converted hardware to Microchip platform. I also converted injector controller software to c. I have used Hi-Tech c-compiler for this project. Original project contains also very good theory and explanation of operation.
I usedPIC16F873 part for this project because of its almost optimum pin count. 16F873 also has internal pull up resistors for Port B. This reduces part count.
