I have a V3 speedo healer for my 07 ZX10R and I cant get it to work.

I have followed the instructions to clear it and then put in a -40% which I think is about right.

The bloody thing just keeps flashing and the best I have got it to is reading 30mph at an actual of 22mph

Anyone had similar problems?

nope mine works a treat, try emailing them, there very helpful

Me and Mr Worx spent about 1hr on it yesterday with little joy so I assume we are doing it correct. I have emailed speedo healer to double check that its not a dud or the wrong one
