Hondata

I recently got my s200 tuned and took my car out. When I was goning through the gears I noticed my speedo jumped all over the place. 1st gear was fine but 2nd,3rd,4th, and 5th is when the speedo started acting up. I just replaced the speed sensor from acura, so i dont know what the problem is. Before I installed Hondata I didnt have this problem. Has anyone had this problem in the past? Thanks in advance.

Make sure the electrical connection on your VSS is plugged all the way in. Mine did this when my connection was loose [the clip was busted].

i agree with DAX, ill put my money on the speed sensor connections if not the speed sensor itself.
