I run an E6K ecu. Ignition is Crane Cams H1-6.about the base map...yes, but the base map was barely used. The guys that programmed it new what they were doing even though it was not the easiest thing to do. 2 or 3systems sounds like it was wired incorrectly...imo. I had mine on my DE and now my VE...not had a problem yet.
