Don't want to sound contrarian, but how would you know the EZ caused the ECM failure? I'm genuinely curious.
I replaced the ECM on a '99 I had several years ago, which hadn't had any electronic fueling enhancements. I was less than impressed by DC's troubleshooting techniques when the ECM was determined to be bad. No rhyme or reason. It was the perfect opportunity to buy a Catcher ECM and not look back.
