Is anybody better at keeping notes than I am? I have a 4.9 in my car and at one time we had the Caddy computer running the Fiero speedometer. Now it is not working and I am trying to remember what modifications we done in the past to make it work. A search here brought up nothing. Appreciate any help. THANKS
This was made for an 87GT and 95 Deville 4.9. Its not perfect. I have a hard copy with my notes and have needed to update the digital version forever. In any case I believe the VSS HI to speedo portion to be correct and it should provide the foundation for conversation on the matter as others chime in.
