I've been doing a little reading on Engine Management Systems. Does anybody have experience with them? When are they really necessary. I have a Chevy SB 350 that I'm thinking of building up with fuel injection at some point. I was pondering getting a closed loop EMS to do it. It would go in my '84 transam. It originally came with a carburated 305 5.0 HO. Its computer isn't programable but you could get a chip burned if you installed the necessary sensors. Could you share you experiences with EMSs and opinions on when you should use them and when you shouldn't. Thanks. ---Rich
