It sounds bang on what is wrong with mine.

I'd say it’s the de-limiter/kph to mph chip that’s faulty, mine is screwed and when on track cuts out at speed, round the 120mph mark.

The speedo has not worked right for over a year and most of my speed is guess work is done by my rev gauge and gear selection :doh: :roll:

I was going to recommend this thread Jon, but the images have been removed :sad:

However it might give you an idea...

click me

Once the chip is replaced it should start working again...

de-limiter/kph to mph chip mine is located at the rear of the clocks and is wired the signal wire on the clocks connector... how could this chip stop the speedo from working,,

Does it intercept the signal from the speed sensor then change it and send it to the speedo clock i had to change mine as at 120mph the clocks used to buzz and my head lights would flicker. Jon i did reply to your p.m on the mods did you get it

Ah, yours is diffrent to mine. My de-limter is in the engine bay not behind the clocks...

Not 100% myself how it works, but that method seem'd to work?!?!
