    today i changed the spark table and icm cleared codes set spark angle to 45. and whilie driving the timing seems high 20sto low 30s. when i am stopped it goes right back to 45-47. what items affect this just at idle. i dont have the cam specs i didnt build this engine. it does have edelbrock rpm heads and superram intake. i took valve cover off and measured the lift at pushrod and multiplied to get a close number on lift. aside from timing changes i adjusted the ve table with your analyzer. i have a new log fill but dont know how to export and enter into the analyzer.
