Re: 67-72 Electric speedo

Thought I'd post a quick update. I had the tune in my truck finalized yesterday, and now the speedo is dead on the money! I drove the truck to my buddy's house in Topeka, and when he was done with it, driving it home, the speedo was within 1 mph of what my GPS was saying. I clocked the odometer by the mile markers on the turnpike, and with every 1 mile on the odometer was 1 mile exactly with the markers. And the needle is SMOOTH! Not at all jumpy like the original speedo, or with a Cable-X.

I'm putting together another one for my beater truck (avatar pic) that's getting a 5.3 4l60e swap real soon!
