smoke switch
#5
I think is what you are talking about is what i would call the MAP sensor. its located on the firewall on the riders side. It will have 1 tube going to it and an electrical plug. If you unplug this plug it will smoke more but its going to kill your mileage some. Hence blowing smoke is lost power. Its by no means the proper way to do it but if you want to blow smoke it will do that. However a "smoke switch" their is no such thing.

Rubberduck im not callin you out here im just askin questions. Why does the ecm need to see boost to give fuel? Wouldnt you just have lose of boost? Is what im trying to say is shouldnt it run just not with as much power and less mileage? I have never done it to my 96' but i have done it on a 95 and it had lack of power and less mileage but it blew more smoke.

It's no problem holic, they are good questions. I'm just going on my experience and also what happens alot on here. From my personal perspective, I've done several injector installs where my dum azz forgot to plug the map line back in. And in doing so, the truck ran extremely sluggish and the only reason they smoked is because of a fresh injector install. And after putting a few miles on them, the smoke quit, and the power never came on until I finally realized I had done it again. LOL
But also, you will catch threads on here where people have a huge loss in power and the end result is a bad map, or map line. But I don't ever recall them saying it smoked more. So that's what I'm basing my answers on. But we all know, every case is different. And your truck may have smoked when it was unplugged. I'm just saying I haven't seen it. But I have seen some of my Dodge guys unplug their maps and blow huge black smoke. And don't worry about callin me out. If you can prove me wrong, that means I learn something new. And I'm definatly not too bigheaded to say I'm wrong. This is what a good forum is all about.

This happened to my truck, was running really sluggish so I unplugged the MAP and it ran like it never had before. Havent replaced it yet, but I did plug it back in. One question, if it was/is that bad wouldnt I have thrown a CEL? I did when I unplugged it.

Yeah I saw your valve adjustment post over there last night. I can't do chat rooms. Two finger typing ain't fast enough to keep up with a conversation.

When the MAP is unplugged it sets a CEL because the PCM doesn't get a signal. With a bad MAP the PCM still gets a signal even if it's the wrong one.
