Hi All..

 

Ok want to (need to!) change the speedo on my Zed as its still in Km's.

Anyone kmow how hard it is to do? Think i'll get the chrome type surrounds while ive got them out too!..so to speak.!!

 

:bow:

Luke at the zcentre sells the convertors you need. Not sure if all of them do it (I imagine they do) but the one I do messes with all the speed sensitive stuff, namely the steering, and auto gearchanges. Best way is to get UK clocks and an aftermarket ECU chip to remove the speed limit.

 

Danny at DTA sells the rings, very nice they are too.

ok cheers - was thinking i could just replace the clock with 'disrupting' anything..straight swap kinda thing, not too bothered about having the odometer(?) in Km's...

not sure if you can do that, i think you can but not sure, either way you simply wont find a UK speedo on its own, whole clusters are rare enough.

ok thanks again..

sure i seen some speedo's on ebay..

You can do a straight swap, and uk spec are much better! You don't get the light crappy sterring that you do with a convertor! PM me, i'll tell you where to get a full set for good money!

You don't get ANY messing with the steering etc if you wire it in properly!

ok - i dont understand ANY of this - changing the speedo interferes with steering?!

sorry - not technical minded - i can just about inflate a tyre!

The theory (that I picked up from here!) is that the speedo signal's first port of call is the clocks, and from the clocks is sent on to the ECU. The ECU varies the amount of power steering and when the rear wheel steering kicks in (and out) according to the speed you're going.

 

If you interrupt the signal going to the clocks using a converter, the chances are you'll therefore also be affecting anything else downstream (perhaps there are ways around this, which ChrisC is alluding to? I'm not sure- I've never attempted to wire a converter box in!).

 

The sure-fire ways to avoid this altogether are a) buy UK clocks (I did that eventually) or b) do the resistor mod to the speedo PCB (which I did first, before screwing up my clocks trying to put speedo rings on, also mentioned above LOL :slap: ) However, LOADS of people use converter boxes without any problem.

 

Any of the ways mentioned will give you the right end results- but UK clocks have to be the most elegant solution, and if you're not too technically minded it's also the easiest :)

How'd ya do the Speedo PCB resistor thing? Whats it actually do? Cos my steering is awful!

Cheers for the info, :bow: think ill get the UK clocks!

Yes, correct so why does everyone seem to think a convertor designed for the job would cause problems? LOL

If the convertor is wired in correctly then it only sends the modified speed signal to the clocks and not everything else thats speed dependent on the car.

 

You might as well say boost controllers and stereo's are cr@p if you're not going to fit them properly LOL

 

Get one from Luke at Z Centre as they're tested on Z's and he knows how to fit them.
