All V-10 MHs 75 MPH Speed Limiter?
I"m on my first long trip from Denver to Moab and UT has 80 MPH speed limit.
Went to pass a truck doing about 70 or 72 and noticed the gas pedal was non responsive. I thought, what's going on? Engine went to limp mode?
I hate that when someone passes me and sits right beside me.
I finally got round him but realized later the engine had power but at 75 MPH , it was done.
My Workhorse motorhome had a 80 MPH speed limiter but it rang out in the IP that said "Vehicle Speed Limit"
Do all Ford V-10 motohomes have a 75 MPH speed limit and ; I guess that's not adjustable?

with a tuner, all is adjustable, but maybe it's because your tire speed rating is 75 and they programmed it to limit it ?

What are you doing driving that fast?
It is a MH not a sports car.

It's based on tire speed rating

Well for one thing, what the heck are you doing trying to g that fast in the first place???????
You aren't driving a race car. Now as far as speed limited, I'm not sure but I have been faster than 75 on occasion and when I realized I was going that fast I set the cruz to 63 and set back and enjoyed the view.
You are supposed to be enjoying yourself, that means taking in the view. At 75 it's all a blur and you miss this great wonderful country. There is sooooo much to see so slow down and enjoy it. If yo have to get there in a hurry, then you aren't taking it easy, so why drive the Motorhome? Fly or drive the Minivan

Yes all Ford V-10s, or at least all V-10s installed on a F-53 chassis, have an electronic speed limiter and no it is adjustable by reprogramming the ECU.
Since you found it just leave it and adjust your driving habits. It's a nice feature that helps us get to where we're going without having to think about if we sent in the renewal payment for the Emergency Road Service. Just because you can doesn't mean you should.

Please SLOW DOWN, trust me the tires are not going to live long at that speed especially on a MH.
Think about the other folks on the road....

The governor shouldn't kick in until 80 MPH. The lack of power you were experiencing may have been due to a steep uphill grade combined with high elevation and/or a strong headwind.
Everyone knows going uphill requires more power but what a lot of people don't realize is that at higher elevations your engine is putting out less power due to the thinner air being less dense and therefore having less oxygen.

Unbelievable. The guy asked a simple question and all he gets is grief about how fast he "SHOULD" be driving. His coach, his choice. Answer his question if you know and if not keep your opinions on how fast HE should drive to yourself unless they are asked for.

Yes, I believe so. I asked 5-Star about this a couple years ago. They said they could modify this on special request.
To date, I haven't run up against this limit, so I've never been compelled to modify it.
As a Pilot, I generally don't like software limits on my flight controls. In the F16, there was a "WAR" switch that would disable all limits and safeguards.

Pegman1, Weeeellllll, actually I disagree with the "His coach, his choice" theory, when you're dealing with safety issues . . . If he is wanting to drive faster than his tires are rated for, or faster than conditions for a multi 10,000 lb rig, possibly pulling a toad,
the "His coach, his choice" could very well become "His coach, MY LIFE" . . .

That's a risk of asking a question on a public forum... you might get a dose of opinion along with facts and pseudo-facts.
