How does speed governor work? Which one is better? What speed?

Why restrict yourself? Just leave her open and use cruise control.

 

I understand but all the governor does is stop you from speeding past a certain speed when you pedal is to the floor. You can just set the cruise at a comfortable speed like 65 mph and forget about it. Believe me there are times you might need the extra speed. Sometimes the guy in front of you is going 65.2 and you’re at 65.8 because of tire wear it would take forever to pass and you’ll piss people off easier to just go 70 and back to 65 when you pass him. Plus in the event of a steering tire blowout you’re going to need a little speed to regain control about 2-3 mph should do. I understand why you want to do it so you never worry about speeding it helps that the truck cannot do above the speed limit to start with but you’re going to want that extra speed just discipline yourself to keep looking at your speedometer and keep it 65 or below when you’re not passing.

 

ANYWHO if you got a newer truck they should have a feature in the ECU to set a governed speed. If you’re set on your way to put a governed speed put 70 and keep cruise control at 65. Older trucks I don’t know how they work with those but the newer ones can have a parameter set you’re going to need a shop that has a computer that can modify that though.

 

I used to drive a truck governed at 64. I didn't like it on interstate took forever to pass with it and on two lane I tended to speed because you get so used to running flat on the mat you just do it without thinking. I realize this in no way answers your question but just my two cents worth. My boss on the other hand loved driving trucks with a limiter he said you just relax in the slow lane and enjoy the scenery.

 

Anything made after probably 2000 will have an electronicly controlled speed setting. You can set it to whatever you want in the ecm settings.

You need to better exercise judgement. Just because it is capable of 90 mph doesn't mean you drive it 90. There are times when the smart move will be to increase the pulling power. You don't want to not have that tool available at the moment you need it. Since you are driving it yourself, you should be able to control your trucks speed and fuel consumption accordingly. Speed governors make more sense when you have someone else driving your equipment, who cares not about the wear and tear on the truck or reduced fuel mileage.

Did you also lower your credit limit on your credit cards? Same argument.

 

Man I must be so far out of the loop it’s not funny. When did it get so complicated you can’t pay attention and drive a vehicle?
Depending on what you’re driving bullydog makes tuners that you can change governed speed every day if you want to.
