You brought up some other ecus. I, personally am most comfortable with electromotive. They had issues when they were beta testing the original tec3 ecu( I was one of the frustrated guinnie pigs) but they fixed the issues and the system has been reliable. With electromotive you get a superior ignition system, and (to me)a simple software interface. Some users on here would be me, feets, hemi fred.
No questions on this system that I couldn't help with.
If you are looking to dump the edelbrock ecu, pm me.
