Electronic Spark Control
Hey does anyone have an electronic spark control for an 87 trans am or know where i can get one? I'm looking for one to take the place of my knock module. We think it might be backing off the timing! Any leads would be nice.

Pretty sure replacemet ESC modules are still available for our cars at pretty much all autopart stores. ESC (elec spark ctrl) is what the knock sensor wires into. Maybe I misunderstood what the question is tho..

Ahh.. I see. I can't say I've seen anything like that myself.
Your sure with all those mods, maybe the PROM might be the culprit instead of the ESC (I dunno..prom stuff isn't really my forté)?
At least this is back up top for you tho..
