were you able to check the physical timing advance with a timing light vs what the edelbrock application says after you made the adjustement in the cap?. I wonder if the EFI computer will now think it has a different timing than the physical one.
I didn't, but I can. I'm working on a header leak that I think is causing me to run super rich, but once I'm back together I'll check and report back.
I was able to set base timing with no issues, so I'm expecting the timing to be where it should be. The adjustable rotor doesn't move the trigger wheel inside the distributor, just where the rotor and post are in relation to each other when a plug is fired.
