I just bought my truck about 4 months ago and its a 2001 4.0 Edge and its has a speed restriction of 90MPH is there a way i can get rid of that so I can make it faster?

 

an xcalII tuner would do it and add about 8 extra hp. They run about $400. It'll also do mph corrections down the road if you add different sized tires.

 

i bought a superchips chip and it got rid of it for me... but ive heard its a hit or miss.. some trucks it will (like mine) and some it wont (like alons)

 

there's a mod written on rougeperformance.com that bypasses the speed sensor circuit. if it don't know what speed you're at it can't limit the speed. be careful though, it is possible to damage a lot of engine parts with this mod.

 

Really? i thought they gave more like 15 ish...

 

It could be. I haven't seem posted dyno sheets in a long time.

 

yea most chips will get rid of it...

wouldnt the amount of HP just matter on the tune? because that guy with the GT-TT they kept messing with the computer to get that last 100 HP...

 

Yeah, they were adjusting timing and fuel curves, but they were doing it custom. Unless you make the tune yourself, you can't adjust those, so everyone who has that tuner will have to same results.

 

whose to say you cant have doug do that for you, or anyone else that programs the tuner?

 

you can its called dyno tuned. but most people with rangers dont spend that kinda money just to gain 2-3 maybe 4 hp, over a normal 15hp gain on the tuner.

 

For one, why would you want to remove the speed limiter? It's a TRUCK!!!!!!! Not a sports car, going over 90, hell going over 70 is a risk because they aren't meant to do that. If you wanna go fast, buy a bike or a sports car that was meant to do it.


The reason that GT made so much power from a tune is because it is an FI car. I have picked up more than 75 whp on the dyno in my blue car before with nothing more than timing and fuel trim changes getting it dialed in. You will NEVER see that kind of increase on an NA vehicle, even a purpose built one as I have owned many that were nothing but race cars.

On a stock ranger or just about anything other than the newer 3v GT mustange and any LS motor base, you won't see more than 15 if God tunes it for you because the heads are about maxed out on CFM and the injector are seeing 90%plus injector duty cycle at redline. There is not much that can be done without dropping large sums of cash to completely redo everything to increase the ability to move air and thus burn more fuel. And my move air, I don't mean headers and cold air intakes. I mean massive head porting, better overlap on the cams to increase VE and so on.

 

^^^^^^

what he said.

 

obviously you've never hit the speed limiter when you were attempting to ditch the police. whoops? did i say that?

 

this topic started in sept.'06. why bring up things from 4.5 months ago??

 

It happens sometimes

 

Patbo8,

The 90 mph limit was a sore point with me too. The Xcalibrator2 tuner will remove the speed limiter for you, or you can set it at 100, 110, 120, whatever you want. Mine has adjustable speed limiter, rev limiter, A/F ratio, transmission pressure, shift points, spark advance, all sorts of user adjustments.
Be careful with the speed limiter - you may not realize what that 4.0 can do. I ran mine once to see if it would go over 120 (that is all that shows on my speedo, it shifted from 4th to 5th between 105-110), it was still climbing after 120 but I have no doubt it would hit 130+. It gets there very quickly!
I don't agree with others saying it is unsafe - it is a matter of opinion and personal preference, but then again, I never drive those speeds unless I am alone on an isolated road... I drive carefully and never endanger anyone with me or around me. My '01 Edge is an extended cab which weighs about 800 lbs less than an F150 and about the same length wheelbase, just a tad narrower. Mine is extremely stable at high speeds, but I run performance tires and shocks and never go offroad with it. I feel safer with a Ford truck-tested-tough suspension at high speeds than I do in a sports car.

 

Is it safe to have a speed limiter set at 90 then hit the limiter with traffic bearing down on you while you try to merge onto the left lane of a 8 lane highway while you try to get to the furthest most right lane?

Tell the PTB to leave me alone and I will govern myself. If I brake the law then I will gladly defend myself to a group of 12 of my fellow citizens, first they have to do their job and catch me. This is the reason that the world is getting so overpopulated. There are so many safeguards for so many things that should be common sense. HOW ARE WE SUPPOSED TO ALLOW NATURAL SELECTION TO TAKE PLACE IF WE CAN'T LET THE STUPID ONES KILL THEM SELVES OFF.



****

 

There are enough morons on the road to worry about without people trying to drive 100mph on public roads with stock Ford Rangers...don't make things worse.

 

HAHAHA I Love it

 

hell im ridin on 35's and i top mine out at 93 everytime i hit the interstate.. i anit scared :)
