how come no one really likes to use the mf2 injector controller? or is that just preference.

 

most peeps ditch it for a different setup.

 

but why is that? is the mf2 setup just not any good. what would be a good alternative?

 

i like it *shrugs*

 

There are those who claim it doesnt evenly distribute fuel. Its more the two intake injectors that they dont like.

Dyno tuning says youre running an OK a/f ratio and turns out all you fuel is going to cyl #4 and you lean out the other three.

 

why would it go to 4? i would have thought cylinder 1

 

Thats the thing, unless you put some sort of EGT or A/F meter on EACH cyl, you really have no idea if one cyl is rich or lean specifically.

but FWIW, there are some people running extra injectors sucessfully in fast cars. that 12 second minivan comes to mind immediately.

 

Cyl 1 is the farthest from the t/b.

It short circuits into cyl four.

They say you can tell by the plugs. #4 is black and the others are white.

 

so what set up are you running?
