leave 'er unplugged, its to much trouble to plug it in, just to turn around and unplug it when you get back.

It wont hurt anything, just be sensible about where you really get into it.

 

where is the plug located and is it that much of an improvement? thanks.

 

It will only work when you unplug your map sensor if you have a Edge Comp or an Edge Juice...It will also not work on 03 and up

 

Has anyone ever proved that unpluggin the map will hurt your truck or decrease fuel mileage under normal drivin (i.e. no hotroddin).

I've heard some people say that it will wash the cylinder walls of oil but thats about all the bad stuff I've heard.

 

I could see that happening if you were just nailing it at every light and blowing soot for all its worth. But for the occasional tailgator, no problem

 

Ran around with it unplugged for 6 months with no issues. Only reason it's plugged back in is because I bought a TST.

 

Well towed up to the Jeep show plugged in and back with it unplugged couldn't really tell a difference. so i guess it doesn't matter.
thanks for the replys

 

If you plan on running it unplugged, be prepared for less power, more smoke, and changing your oil often to help prevent damage to your shortblock.

With the MAP unplugged, your computer also does not know how to adjust timing/fuel for the engine per how much boost there is.

Too much fuel does not allow proper combustion reducing power. Not only will it wash the cylinder walls and allow the rings to drag, but it will get in the oil, reducing its lubrication and sooner than later start taking out bearings.

It is not worth the extra wear on the engine just to see more black soot.

Id use a switch on it if you really must over fuel the engine and take its knowledge of what the heck is going on under the hood.

 

Um. I'm gonna have to disagree. Most everyone that runs with their map unplugged with a Comp has reported no difference and some have reported an INCREASE in power. I noticed a nice increase in the bottom end of my truck with it unplugged. All it does is that instead of letting the comp gradually add in fuel, it throws full fuel at it right off of idle. That's it. My truck and a ton of other people's trucks run perfectly fine with no loss of power, no increased soot in their oil, nothing. Is it a little harder on the engine? Probably. But since when is adding more power and more fuel not hard on the engine.

Unplug the map sensor and go and have fun. Just be light on the throttle until you get some boost built and you'll be perfectly fine.

 

Ya i love the off the line power it gives me, now i can't stand not having that power. Are there other ways to get the off the line power without unplugging?

 

i had mine unplugged for awhile now but plugged it back in after the whiplash i had gotten from it too much bottom end for me

 

That detail was left out, becaues the comp tricks the computer w/ map sensor settings anyways.

I was referring to those that just unplug the map w/out performance boxes.

The comp is modifying timing in place of the map sensor. If there was no performance box, the computer would never change timing.

Guess i should abeen a little more clearer.

 

Well the only reason to unplug the MAP sensor is if you have a comp. Otherwise by all means leave it plugged in. The original poster has a comp and was asking about whether or not he should leave it unplugged and that's what I was referring to.

I noticed a very nice increase in the bottom end with my comp unplugged.

 

I just ate a krispy kreme before posting, was sugar highed and jumped to an answer before reading. I blame it on the donut.
