Glad you are closing in on the problems though as I am with my roller rockers/mod
Dave,
One thing to consider, while my EFI is a programmable unit most of the later offerings are "self learn", eliminating any direct interface to base fuel/spark maps, or to any of the myriad of correction curves that I've dealt with. In fact, if I simply changed out my O2 sensor to a wide band unit, inserted a different 'plug' into a harness port, and uploaded a new firmware package (free from Edelbrock) I could convert mine to self learn. I already have a wide band O2 sensor, bought to help me tune the air/fuel map across the load range, but with all of the time & effort I've invested I'm too stubborn to change. I simply enjoy the challenge of the various curves and maps, and making small changes to fine tune things now is part of the fun for me.
