Have a butchers at these, £40 off a guy on ebay, seem pretty good quality on first inspection, I'll let you know how they look when installed.

[pete shrimp]

Cool they look great!

you'll need to re-calibrate your speedo as that's a US one that goes to 160.

Uk ones go to 180

Jap go to 190 ( or the other way round, don't remember)

[davido140]

arrrrrrrrrgghhhhhhh just spotted something very bad! the Jap speedo goes to 180 right!!!! look at the speedo on there!!! only 160!!!! nooooooooooooooooooooooooo!

 

(you were right about the quick edit BTW!!)

[pete shrimp]

I think a suitably placed resistor will sort it, dunno what size though. Or some tippex and a marker pen ;)

[davido140]

hehe you beat me to it jaffa!!! I guess I'll be doing a search on recalibrating the speedo then! :)

YEp, I bought a set and never fitted them

160mph!!!!! Bugger

 

Ill probably sell mine if offered right amount.

or fit them if I can get recalibrated.

I'll let you know if I find out how to recalibrate the speedo! cant say Im too bothered about missing those extra 20mph! never go that fast anyway!

Its not the top speed which is the issue (much ;) ) its that your indicated speed will be lower than actual throughout the range. I'd imagine it'd be 11% too low (1 - 160/180)

[davido140]

thats some snappy maths there pete! ;) You can adjust the speedo using some pots on the back right? wonder if there is that much adjustment in them... hmmmmmm

Just done some sums! the error is going to be accumulative, sooo for every 1mph on the clock im actually going to be doing 1.125mph which means

 

20mph is actually 22.5mph

40 is 45

60 is 67.5

80 is 90

100 is 112.5

120 is 135

140 is 157.5

160 is 180

 

That is if the Jap speedo maxes at 180. Throws it all out if it maxes at 190!! can anybody confirm please?

 

which im hoping can be corrected using this method...

(thanks mark W for doing the ground work!!!) just hope there is enough adjustment in the Pot!!!

Jap speedo whilst the last number is 180 there should be another marker after it, making it 190. Uk specs stop at 180.

cheers

[davido140]

Thanks smithy!

 

So that means the offset is 1.1875 per 1mph

 

20 is 23.75

80 is 95

120 is 142.5

160 is 190

 

All hail my mighty maths skills (ok i know its simple but its pretty impressive for a dunce like me!)

 

Now all I need is my bleeding car back so I can fooking well try it out!!!

[davido140]

hahaha im such a lazy git, Cant be arsed to do all the messing around so luke at the Z centre is going to fit a set of his dials for me! bit more expensive but saves me a day of d1cking around in the rain trying to get them right!
