[katLOL]

Hey guys, got a little problem. My speedo is reading very slowly, like its so bad that my car doesnt register speed so if my launch control is on it dont turn off because my car doesnt register the speed. So saying im not sure of what to do. I put it a brand new speed sensor this winter. so i need some help to make this car register some speed out of the hole, Please help!!

What chassis is this in? Did you match speed sensor with the chassis?

[katLOL]

Yes, its a s13 hatch with s13 blacktop, and i have a s13 KA speed sensor.

check wiring?

Did you try swapping in a new cluster? If so, then you may consider checking wiring like ^he^ said.
