Are you running standard wheels and tyres? If not they'll throw the readings out.

Wait, 10mph at all speeds?

What happens when you do 5mph? does it read minus 5mph??

The needle doesnt move unless your doing over 20mph

I suspect the clocks, might be worth getting some UK el dials and ditching the converter box at the same time?

Do you have Vtec in 1st gear?

Checked the connections, theyre all good, ive got vtec in first, dont really want to swap clocks ad i like the el dials, im not majorly bothered about it, was just trying to see if it was a simple fix

If you have Vtec in 1st then its probably not the VSS and must be the clocks. Worth just keeping your eye out for a UK set of el's, they plug straight into a JDM and will read in MPH without the converter box.
