hey everyone im new to the forum..i have a 89 240sx with a s13 sr20det swap...got all the wiring done but there is no rpm readings..i even installed an autometer sport comp but still no reading...could this be a wiring error...some advice would be great...thanx!!

i have heard that the s13 tach doesn't work with the sr swap. try either a 180sx tach, or a 91+ DOHC tach is supposed to work as well.
