1986 GMC P/U with ESC

(1/1)

tayto:
My 1986 GMC 1/2 ton Pickup has electronic spark control, basically just knock detection and it can retard the timing. It has currently been bypassed, but wondering if it is worth repairing. I will be swapping in my 355 over the next month. The internet says to get rid of it, but i don't see any harm in pulling timing if knock is detected. Thoughts?
