|
|
Ok, my tachometer is WAY off. I discovered this when they took my emissions test, and it makes since since according to my tach I idle at 1200 RPM.
Is there a way I can measure my true RPM easily, then just know that my tach is off by X amount? |

Our tachs are well known around the world for how inacurrate they are. |

| Is there any way that I can figure out just how inaccurate it is at redline without spending money? I leave for basic in two weeks, and until then Im broke. |

not unless you can find someone up there with an ALDL cable and computer, but then you are still going to have a hard time. Chances are you tach will end up looking like mine.
