Help with Speedo question.
Help with Speedo question. Hey guys I have a 69 camaro with a LS1 and T-56 in it. I want to keep my stock gauges. Does anyone know of a look alike that would work off the pcm signal. If not I have a converting box that will drive my speedo. Does the pcm need to know wheel speed if I use the converting box. Thanks for any help.
check out speedhut gps speedometers. They have old muscle car factory style gauges and are calibrated by GPS, no need to go off tire size rear end ratio etc...
take a look they are cheaper then autometer too.

checked it out didn't see any factory gauges on their web site. I e-mailed them to see if they could help me. If I use the signal converter is ther any need to to send the speed sensor info to the pcm?

Yep, just use the speedo output from the PCM, set the dip switches for 4000 pulses per mile and you're good to go. Abbott Enterprises will tell you to tap directly into the speed sensor wiring, which also works, but hooking it to the PCM is easier.
Thanks that is what I will do if I don't do the mechanical mod on my tail shaft. I already have the cable-X box. I used it with my 383 non LS motor. I didn't like that it fluctuates a bit with speed change. I can live with it if I have to. I also, with searching the forum found that a stalling issue could occur if I didn't let the pcm see wheel speed. Thanks guys for your help this site has helped me so much. Thanks Again!
