time for an update again.
So far so good until today. Found out that the integra speedometer isn't very accurate. Reason i say this is because the s2000 gives you a digital readout(very accurate). Where as for the integra, i am eyeballing the reading off my ls speedometer. So, overall still good but may not be accurate to +/-4 percent of actual reality speed. Government requires all US cars to have that close of a tolerance.
As for generating a speed readout on the s2000 cluster, this was successful. here are some spec for the s2k cluster, the following information could not be found anywhere in the internet because I tried to look for something to compare too and can't find shit.
to get mph you must supply a 12v square, 20 percent duty cycle wave to the signal input at the rate of ....

I am going to need a digital speedometer for an integra in order to finish to get specs to where i would like them to be. SO DOES ANY HAVE ONE THAT I CAN BUY FOR CHEAP OR BORROW?
Look at ratios and you can clearly see why a direct wire hook up to the integra VSS signal will not work.
Enjoy guys..... The only reason why i am giving out this information(could of kept it private) is for the better of our site and to promote the world of automotive electronics. Because when it comes to engine building, information is left and right but electronics are discussed, things are too quite.
