i have a Dynatek EFI controller and im getting me some dmc force 4s this week and i dont have a clue on how to use it any1 know some good settings? i just have the big 3..and how can i tell if its lean or rich?
well the controller is pretty easy. the base pot sets it to a certain fuel curve. then you adjust the other 3 to fine tune it. to check if your lean, get on a long straight. start really slow in second and give it full throttle. once it revs to the max or so turn your switch to off. pull the plug and look at the color. black is too rich, really light tan is too lean. it should be a medium brown color. the outside will almost always be black, so just look right in the center of the plug.
It will change after a short ride around the house. If its good not it is going to be a bit lean when you install your exhaust. Get your duals on there and ride it around for a couple of mins make sure you hit full throttle atleast once and then go check your plug
