What engine do you have? Because if what you want is something simple you can put in the admission collection near the cylinders some injectors mounted on a Ramp of the Seat Cordoba type of 99 and a Hall collector in the camshaft, with an electronic module that tells them what momnd should have had.
Note: The only aberration like the one that your Sujieres, in Spain is a Ford Mustan of 67 V8 with mono -to -side injector a barbarity to make it work and works very badly.
But nobody tells you that you can't do your do it and alomejor you get it to work
Hello, if it were to carburement, you would win in simplicity, absence of breakdowns, reliability, remember that the carburetors "do not think" but obey the pedal, if they are well regulated. Adapt an injection like the one you want needs enough variables, collectors, manage without caudalimetro in multiple, etc.
