Speed limiter, Help needed

Hello,

I am stuck trying to modify the set speed limiter on my 2019 f250. I live in Finland where these trucks unfortunately have to have a limit to 80kmh. The problem is, when changing tires to different size, the speed needs to be corrected.

I have learned that the speed in my truck has been set by lowering the trucks 100mph original governor, to 80kmh.

So if possible, what is the easiest/cheapest way to modify that particular value? I do have forscan and icarscan.

Br. Mike

You should be able to adjust tire size with Forscan:

As njburn said, use Forscan to correct the tire size and thus the speedometer.

Or are you trying to remove the speed limiter? There may be tuning options for that but I don’t have any idea how you’d get anything implemented in Finland.

I can order whatever here if someone can advice me a gadget capable of doing this. Tire size correction does not get me to safe overtaking speeds. As said, it is now restricted to 90km/h. Thats like 60mph. It is done by modifying the factory speed limiter.

checkout fivestartuning in SC, USA, they may be able to help. Note, I have no affiliation with them other than purchasing from them in the past.
