People dropping FI setups like hot potatoes

I had my F.I. on for 2 years before the ECU in it quit. Car ran good, 472 Hemi with 2 throttle bodies. I got stuck at a gas station and had to have car flat bedded home. It wouldn't start when hot. Started ok cold. I would recommend carrying a carb for when the FI quits on you. The ECU was replaced under warranty, but I no longer have confidence in it.
