does anyone know the answer to this quaestion? the fmu came with the d16 sohc greddy turbo kit....just wondering any thoughts?

 

i dunno what the ratio is, I just know it works by detecting MAP signal (boost level) and reduces that signal to the MAP sensor (to prevent a check engine light) then it controls the 4 injectors to make them pulse longer...
It seems more true time than a ratio to me.

 

Are you sure? My FMU works by reading boost pressure from a vac line and pushing out a 12:1 ratio of psi of boost to psi of fuel. You probably have a 12:1, but don't quote me on that. That's what I have in mine.

 

The greddy kits don't include an FMU like what you have. They include an electronic piggy back device.
