shift light help
shift light help My shift light reads slow for some reason. It is set for 6500 and the rev limiter is set at 6800. Well in any gear 1st – 4th I am bouncing off of the rev limiter before the light comes on. I have double and triple checked all connections and settings. I have also move the signal source from the PCM tach wire to the #1 coil pack and set the light for 1 cylinder and it still reads slow. The light comes on strong at settings lower than 5500 rpm but the actual engine speed is much higher. I also replaced the light thinking that was the problem. Nothing has seemed to work. Does anyone have any suggestions?

if its not led's it will still read slow incadescent lights do not light up quick enough for the eye to catch it

I have also tried a friends Harlan. The lights work in other cars but in mine they read slow.

that power should be ok but id try the fuse box there is an open ign only circuit that you can plug into there
this is the wire u tapped into right? only other thing you can do is verify the pcm tach output with autotap or efi live and see what it shows for rpms

almost sounds like thers a glitch in the computer over 6 grand then . the light works, connections good , car runs fine just the output signal is a lil screwy at high rpm, so im leaning torwards internal in the pcm
