For the people who have had to replace their ecu; What problems were you having before you replaced it. I sent my ECU to get mail order tuned and when I installed it i got all kinds of issues. You can read about it on this forum https://www.camaroz28.com/forums/sho...d.php?t=541382 Im not going to go into that. But any way I was wondering if any one had any issues with extremely rich fuel delivery with a bad ecu? I know its a general question but all well. I was thinking that a ECU can get messed up while being shipped. Has that happend to any one?
