cruise control/computer question
Hi,
I am swapping a sbc 400 in place of my 3.1 in a 91 RS. I want to keep the cruise control. Do I need the ECM inorder to retain cruise control?

I don't know if your car will function the same as my 85 with mechanical speedo, but check the following link for some info:

Yes, the ECM recieves the signal from the VSS and relays a slightly different signal to the cruise control module. 4000 pulses per mile and 2000 pulses per mile respectively if I remember right.
