I now have my swap complete to d16z6 and I had a but of a question....I did not swap out my cx cluster and it seems like my speedo is off. Is it necessary to swap back to the original cx VSS or is correct? I have no way of really telling if its correct or not but it seems faster than I am actually going.

 

you don't have to not unless da z6 vss is bad which is throw u CEL17 if bad. How much u think ur off on ur speedo anyway......

 

no codes...just seems like im 10 or so off. Im gonna try to see if I can pace myself with wifes car tomorrow. Could be me...I didnt think the vss needed to be swapped, but it just feels off.
