jumpy speedo??????

[GTSAARON]

Hi Chaps and Chapettes,

For some odd reason, on hard acceleration my speedo needle has a tendency to flick suddenly upwards by 20 mph or so for a split second, before returning back to where it should be. Any explanations welcomed

what type of speedo Delimiter / converter do you have fitted? sometimes the cheap ones cause problems like this

[GTSAARON]

It was a chip from SVA parts down in Southampton. Cost £25 and just wired it in myself. I bet it has something to do with the delimiter though. The actual speed reads spot on in mph when its not jumping around all over the place lol

Could be speed sensor on gear box.

or the cable coming to the end of its life if it is a cable type of course

I would take the delimiter off and take the car out again and see if it does it.

Mine had a cheap delimiter fitted (Little black box with 3 or 4 wires comming out of it) and the speedo would jump all over the place eg driving at 60 mph and all of a sudden it will flick to 70 or 80 mph for a few seconds then back down to 60.

Also when I flashed my headlights the speedo would jump.

I bought a Clamping Delimiter, cost about £60 but it sorted the problem out
