I have one of these - very nearly the same model. On a journey down the Fosse Way a few years ago, she had laryngitis and couldn’t do much more than whisper. Our journey time was reduced by 30 minutes.


Me also. Must be the secret optional extra that comes FOC with every passenger seat!

Did your MPG drop as well ?


There was a minor change- around 10% IIRC. Don’t tell Mrs F - it adds to her “justification” for her role as arbiter of speed in all situations.

About the calibration of the speedo, I‘ve got a 2018 plus4 (german Model) and the speedo has the same difference.

The difference is exactly 10%. So I drive 77KM/ it‘s real 70KM. I think it‘s wrong all over all MOGs from factory.

On the way home from Britain this year my friend and me want to know what she‘s able to do...
The speedo shows 190 KM/h, the nav says 172. (German Autobahn without speedolimit - clear) So I think the speedo shows the wrong speed all over the dial.

For now the Sat Nav is in use though at 2000 rpm

50 in 5th
70 in 6th

60 is 2.5k in 5th
Based upon the sat nav & your spreadsheet.

These are the same for my 09 Plus 4

Rene,
mine under reads so 70 is 77 mph. That I understand is illegal. I beleive car speedo should show the speed with a range of -0 to +10%.
The way my car is set up is n opportunity to lose my license.

We must distinguish two things here. Do I want to read an exact speed indication while driving? Or do I want to know exactly how long the distance travelled is in miles or kilometres?
As I have experienced, the relationship between these two objectives is fixed and unchangeably programmed.
So if you want to see the exact speed while driving, the odometer does not count enough kilometres driven.
If you want to see the exact distance, you will see more speed on the speedometer than it is while driving. This is because the speed indicator needs to show a little more than is. Strictly according to the law, the odometer has to be calibrated, and consequently the speedometer shows slightly higher values. Of course it should not be too much.

Didn't realise the 10% error was in that direction John given as you suggest, a speedo that under reads is illegal. Most over read to the tune of 5-8% as you know. Suggest having a look at the Mustang forums on this subject. A further thought is your factory modified PCM (ECU) may offer more tweaking opportunities given its the device the gearbox output sensor communicates with [Linked Image]. Indeed that PCM may be the cause of the issue, as I believe the testing Adrian (AJSki2fly) did on behalf of MMC involved such.

Oh, John, yes. I was wrong. My speedo is optimistic and give me the illusion of a 120miles +4...

A speedo with showing you ´re to slow is also not roadlegal in Germany. And as Heinz sayed, if it shows you are too fast/ slow it´s the same difference in the distance you drive.

Correct.
Both my 4/4 have under read speed (it's why I have added GPS based speedometers). I think in both cases (they were/are mechanical) that is likely due to lack of use by previous owners. However, as yours is electronic, it sounds as though it has been incorrectly calibrated.

I think so Graham along with the fuel gauge. B&C are working on it.
I know other Roadster owners where it was spot on.
My GPS speedo arrived today so will add that.
