just to let you know the carburator is a thing of the past
I have heard of BCM,ECM, and ECU's but never heard of a EMS on a vehicle nor have I ever heard of one shutting down a system as a precautionary measure. Just worked on a $65k Caddy earilier and asked the techs about EMS and none of them knew anything about it. They said any such thing could be a liability issue especially if they decide to "go into protection" as you are driving 80MPH down a 8 lane highway.

They did say that there are "limp modes" that are programs the engine goes into if some sensor fails. Usually this will result in a ck engine light but the vehicle will still run. It may run a little worse since it may not be monitoring all the data but it will run.

BTW, yes I do not all about fule(fuel) magement systems and such. I am in the process of making my old 'Bird into a fuelie. Obviously I need to know about these anyway when doing remote starters.
