Re: Question on msd 6-al ignition tach output

Hey Jim,

That's good news! - - the switch settings would be helpful, but I know how hard it is to take my dash out and I don't think you would enjoy that experience just to read switches for me! besides, there's only 8 combinations, and I already know one that's crap!

my guess is that since the "v8" setting is exactly opposite of the "4 cylinder" setting and my tack is reading 2x actual rpm - i'll give the 4 cyl setting the first try!

i'll try the switch flip as soon as i feel like pulling that damn dash!

Thanks again everyone!

Dave
