How or where do I set the base timing with the speed-pro system? I couldn't get the car to quit pinging after checking everything finally as a last result I changed the car from a crank reference angle a 8 degrees to 15. This took away the pinging but I dont know if this is correct. I dont want to sound dumb, The problem is I bought the car with the system installed (ANS) and don't know if the previous owner had moved it or if it was never right. On my 90 chevy I have an Edelbrock Pro-Flo systems and it is simple put ecm in base mode timing set and make sure the balancer reads 10 degrees. Speed-Pro unsure? Where is the best place to get a installation manual for the Speed-Pro system? Any help would be great Thanks
