VSS issues, at wit's end
93 Sol SI, still has the z6, and the speedometer hasn't worked since i've had it. its never bothered me, until i bought a new ecu so i had vtec. the ecu has been tuned, i think for a turbo b18(burner is on the way, so i'll pull the tune from it and find out by wed) and has a 2 step.
I like the way it'll launch on the 2 step, but the problem is, the 2 step likes to engage, then disengage, then re-engage. its as though its getting bad signals from the the vss. i just replaced the vss, checked for key on 12v to body ground, then checked for 12v from the ground wire to the battery, both showed atleast 12.6. i then checked for continuity on the signal wire between the ecm and the vss, and it has continuity.
my speedomeer and cruise still dont work, and 2 step still kicks in and out. i'm at a loss, because it appears to me that as long as there is continuity on the signal to the ecm, it shouldnt matter if cruise or the cluster are good.
any ideas?

Re: VSS issues, at wit's end
I have a 98 civic ex, speedo was not working so I bought a new vss, speedo still didnt work. Returned the vss and started looking at the wiring. Turned out to be the female end prong on the hot wire (middle of the 3 wires) on the electrical connecter was corroded. I snipped the connecter, replaced the female prong, chickleted the connector back to the wires: speedometer, odometer, tripometer now all work, check engine light gone.
Check your wire connections for corrosion. Might be your issue.
Hope this helps in some way.
