Speedometer Adjustment - 2011 Expedition

[Jozef Zoldos]

I put a lift kit on my 3rd gen Expy with bigger tires and now my speedometer is off by 5%. I know that this 5% is not a big deal and it works in my favor with the odometer advancing slower than the actual mileage of the truck. Nonetheless, I am looking to fix this. I previously posted and did not get any real solutions. I tried to see if I could adjust with Forescan even posting in the Forscan Forum .... nobody was able or willing to help. I went to a local “performance shop” and they quoted me about $550 to fix; $425 for a VIN-specific module and $125 for labor. That’s too pricey for me.

Is there anybody out there That has any reasonable DIY solutions for this issue?

Thanks in advance.

Now is a perfect time for a 5star tune!

I looked at the website. What can I expect with a 5star tune?

Better throttle response is the main benefit, they can customize a tune to your liking. You should see a small bump in power. You can also tweak your speedometer settings to account for larger tires, you can firm up shifts if you want, take out your top speed limiter, etc.

Forscan will not work. You will either need a tuning device of a actual speedo calibrator. Might as well tune it
