Speedo correction

This only applies to 1 lambda bikes ( eg GRiSO, Sport, 2V Norge, Bellagio).

If anyone has a discrepancy between what your speedo indicates and actual speed measured via GPS, and would like to fix it, it's quite easy.

First, you need to know the percentage difference between your speedo and actual speed. A GPS or smartphone with a GPS app, or speedo app will do.

If your speedo reads 110 while your actually doing 100, it's a 10 percent error. OK, elementary mathematics completed, we need to adjust the speedo correction in the map.

If you have TunerPro, simply load your current map in and have a look at the Speedo Correction table.

If your speedo is fast by 10%, modify this value by increasing it by no more than 8.8%. The value should not be equal or greater than the discrepancy. Always go about 1.2 - 1.5% lower. I will not be held responsible if you get nabbed for speeding.

If you want to fix this but aren't sure about doing it yourself, send me a PM. I'm happy to modify a map for you. This includes those who are using a factory map.

This will be my last post for a while. I will respond to PM's, and will lurk from time to time, but I won't be posting in the forum, or responding to question unless they come via PM.


Have fun!

??? Thanks. And I hope all's ok.

Well Mark, I never noticed that was missing in the 2 lambda xdf, I took a look, its on 0x4EBDE If you copy the speedo correction thing over from a one lambda vexdf, and change value to 0x4EBDE you can set it on the two lambda bikes. And I'm shure its right, the stelvio and norge 8v have different values that are the same as the one lambda bikes.

You're not gong to the hospital again, are you?

Thanks Paul. I thought I might be off to hospital, but they've got me on good drugs. Seem to be working.

Hey Mark. Glad to see you are back already. It seems that mr bones has taken a hike. He he. I hope he comes back with different attitude.

Will taking those drugs with Bourbon decrease your pain?

Actually, not come back at all. You can't fix stupid!

Don't poke a sleeping dog. You may get bit.

Mark - the speedo correction you did on the 1200 sport along with the remap has been fantastic - at least I now know the exact speed I am getting booked for. I gave the sport a good poke along on the way to work this morning and bloody hell it was nice and smooth with a ton of grunt - many thanks buddy

It was good fun Mike. The transformation of that bike was astounding.
