Speedometer Test

Hi All

We have rebooked the IVA for 26th Aug as weren’t going to be ready

This came back in the email and my question is

Does the IVA still check your speedo ?

My issue is Ford Type E needs 90deg adaptor no longer available
I’m looking at Hall effect and electronic speedo otherwise but bit stuck to be fair

Thanks

PLEASE NOTE : From 16th June 2025 IVA 1C applications for M1 vehicles can now be completed through My Vehicle Testing (MyVT). PDF forms are no longer required for these vehicles.

May 2025 versions of the IVA 1P and IVA 1LG PDF application forms are live on the Gov.UK website. These forms became MANDATORY for customers to use from 27th May 2025. Any prior versions submitted from this date onwards will be rejected.

Due to the cessation of speedometer speed roller testing at our test sites, if you have fitted a speedometer to meet the required standards, you may need to provide evidence of its accuracy to prove compliance.

I have used this https://www.burtonpower.com/ford-electronic-speedo-sensor-revfss.html
in my Stylus along with an ETB electronic speedo. It fits directly onto the speedo drive in the gearbox and doesn't need an adapter.

I've done 3 IVA's and on each the speedo was checked on a rolling road. I am not aware of this being cancelled and will soon be goingfor another IVA (probably after you though)

If they are no longer using the rolling road (I'd not heard that, but somewhat out of touch nowadays) then you would need to be able to prove the speedo was set up correctly, say by saying it has unaltered gearing from the original & you're running the same size tyre or similar

With my first Furore, the speedo drive wheel & sensor for the electronic speedo was only on one driveshaft, if you run that up on a rolling road every possibility that the diff would favour one side or the other so wouldn't be accurate, but if you have calcs to show that for the tyre size you have & how many pulses it needs to read 1mph, 10mph etc then they have to accept that

They are still gonna drive it round the yard for steering self centring etc & if the speedo doesn't read or reads something obviously way incorrect you'd obviously fail

That looks a LOT more straightforward, they've dropped the roller test completely

and only you have to show documentation if the visual checks indicate it is 'obviously functioning incorrectly'

ie it just has to look about right.


"Note 6: Where it is determined that a speedometer is obviously
functioning incorrectly, additional evidence relative to the type of
speedometer fitted should be sought, in the form of:
• A receipt for the conversion from km/h to mph, or
• A receipt from a component supplier (i.e., from a speedometer
conversion or an interface/chip installation), or
• Manufacturer’s instructions (e.g., installation and calibration), or
• A rolling road printout."
