FI recommendation for 360 Dart

I had a Fitech set up in my car and when it failed I went to their Forum and it was common for the ECU to fail. It had nothing to do with installation or any other problem after it left the factory. As I said ran good for 2 years, and then the disappointment when it wouldn't start. I also had 1/2" spacers under the throttle barrels to keep them cooler to no avail.
