My speedometer is registering a little fast. it was a swap from an LX. i have a CX. 94. i wanted a tach.

so my question is, how do i re-calculate my speedometer?

also. when my tank is full it registers that it is only a half full. how do i fix that?

You cant re-calibrate the speedo or vss (vehicle speed sensor), how big are your rims if you have them?

Change your tire size.

I dont know that there is a way to change the speedometer

stock rims. stock tire size.

car that it came off of was the same size tire as mine.

anybody know what the stock tire size for a 92 LX is?

+its not the vss that is off... its the actual gauge cluster. now you can pull it out and try to manually adjust it... like if it's saying you are going fifty but really going 40 you can move the needle down i believe and vice versa...

A friend of mine did that don't know how well it worked but thats always an option to try or you can try a new gauge cluster and see if that fixes it.

And you saying your fuel gauge is messed up it might be that you have a bad cluster.
since 2 things are wrong on the cluster it could be that it is just bad. Also try pulling it out and unplugging and then plugging all the plugs in all the way see if that does anything

If its indeed off then, try swapping clusters with a friend then to see if that fixs it. Seeing as how the gas gauge is also off.
