Base timing question on LT1
When the optispark is installed properly there is no base timing that is set, correct? Its a set value from there on that is adjustable only by the ECM, correct? So its not like the HEI distributors where its possible to inadvertently/mistakenly advance or retard the base timing off the factory default setting, right?
