93, 3.4L uses a 16149396 I'd kinda be surprised to see a SEFI 6 + 8 using the same ecm. Based on past gm strategy Grumpy | It just occurred to me that I have NO CLUE what I'm talking about. It | occurred to me that the 93 3.4L SFI Camaro would be more likely to share | the V8's '278 unit, not the older F-Body's 727/730 unit. | Sorry about that!
