Well.....thinking about the computer systems used in 'our' cars, seems like having that adjustment on the coil pack would be null and void ne ways since you regulate your timing curves thru laptop programing. Then with a stock ecm....seems like the chip would do the same as well-override the adjustment knobs all together to maintain what the chip is set for on the timing curves.
