I have the autometer shift light with the little pills and if I put in, for example a 6.6 rpm pill in, the shift light comes on around 7k so it is off by a few hundred rpms. I have it tapped in behind the cluster, would it be more accurate if I tapped it in the blue wire by the master cylinder? I've heard that the autometer tachs and shift lights are usually off by a few hundred rpms, anybody else have this problem? how did you fix it? TIA

 

well thats sucks if its unaccurate!
..but ive heard the stock tachs are also inaccurate...
good luck, heres a bump.

 

thanks for the bump, ttt again. anybody else?

 

when my car idles, its not accurate to the autometer, but when i drive off, it seems to run at the same rpm.

 

i tapped mine into the ignition coil..i would say my aftermarket tach is more accurate

 

I just tapped into the blue wire by the master cylinder and it seems accurate now. thanks fellas.

that's the wire you are supposed to tap into

I just got my pills today. The shiftlight I bought from a user here only had a 6K pill got my 8400 pill in today.
