I replaced needles and they are a little off calibration. I just want some specs/info about the rpms and speed on the tach. thanks

 

may OLT can chime in but when I calibrated mine I made sure that both needles were at zero when the key is set to on but with the engine off. with the key out setting it to zero didnt work for me because they actually move up to zero when you put the key in.

 

at 20 mph, that really depends on what gear your in, and your tps calibration too.

I can tell you for sure that at 80mph its exactly at 3000rpm in 4th gear.

 

thats exactly what im facing... at zero it reads faster then you actually are, and the rpms are higher
