kenai Posted February 24, 2007 Share Posted February 24, 2007 Hey I have a quick question....i installed a 40 pulse vss on my 4l60E lt1 combo. I am getting good voltage from my VSS into the PCM (put the car on stands and put it in gear) but the out to speedo wire (D8 i believe) just sits at .5 volt ac no matter how fast my wheels spin. So, i checked to make sure that its programmed right and everything checked out. So then i just wired straight from the VSS to the Speedo and everything worked fine. My speedo is an autometer. Its like the PCM out to speedo isn't sending the right signal? Do most of yall just run the speedo right off the VSS? thanks! Quote Link to comment Share on other sites More sharing options...
Poundz9oh9 Posted February 25, 2007 Share Posted February 25, 2007 You can never really go wrong with sending the VSS straight to the speedo. I can't really speak from experience when dealing with a PCM, but, for my T56 istall I ran it straight from the tranny to the speedo, and it worked GREAT!!

m1noel Posted February 25, 2007 Share Posted February 25, 2007 That is right, you should use the lead from vss before it goes into pcm. Mike Quote Link to comment Share on other sites More sharing options...
