Hi guys,

 

converted zed to na rear diff and subframe,

and speedo is really out.

Seems I'm going along in the slowlane at 100mph.

 

Either that or ka's and lorrys are getting a bit fast lol.

 

It's not so bad till around 50mph sat nav being few mph out, but has the speed gets up it's around 15 to 20mph out.

 

Got a standard ecu on for the moment and Consult says it's limited to 115mph, but on a private rd limiter kicks in at just over 130mph going by clocks.

 

Is there a way of fitting na speed sensor, or a known fix don't like speedo being out with all these yellow boxes hiding around here.

 

Thank you.

Nope ..

 

Just Move your needle about 5mm down this should give u the right speed .. but check with your sat nav 30mph 50mph 70mph

 

30 should be spot on

50 1mph under

70 2>3mph under sat nav speed

HI mate,

 

cheers for the advice, just went and done it,

drove with front of clocks off and now pretty much bang on with tom tom.

Hope the tom tom speedo is much right.

 

Only thing I noticed is when I 1st pull of hand takes little longer to start going up.

But that may be how it's ment to be.

 

See how it is next time on the motorway, when the lorrys ain't doing nearly 100 lol,

 

Thanks again.

You can also calibrate the speedo by adjusting the potentiometer on the speedo board, you would need to drill a couple of small holes in the top of the plastic dash and use a small flat blade screwdriver to adjust.

Thats how i did my speedo calibration, just a bit of a nightmare driving and adjusting......

 

Al.

Cheers guys, I will see next time I'm on a run along motorway if it's still out.

If so is there a pic of the screw I'm supposed to adjust.

Never played with speedo before.

 

I'm lost lol.

another job to do :rolleyes:

Thats the little puppies............ IIRC, 1 does the deflection at speed and 1 does the rate of deflection from speed..... If that makes sense. The best thing to do is drive and adjust as you go.

 

Alz.

Oh god that sounds and looks complicated,

u mean I gotta race them 100mph ka's while looking at them lil screws.

I hope it's ok now.

 

Wasn't expecting pics like that thank you.

Hopefully I don't need to use them.

 

Thanks and thanks again lol.
