Speed meter questions

[WRXONP]

Hey guys

A few questions about speed meters like the pivot speed meter or the apexi rsm and the likes

Do they all need the factory speed sensor as the input ?

Can u use a speed meter in place of the speedo for wof purposes ??

Reason being my new car has a newer 6 speed trans fitted into it and the factory 5 speed houses the speed sensor on the out put of the gearbox - and the 6 speed model runs the speed sensor off the diff - and the duffs are very hard to source

My pickings are that if one were to not use the vss it would need to use gps ?

Cheers

I think if its (speedo) there it has to work, like fog lights, but they might look over it? but if your km's arn't changing ....

but if you remove it im sure they will ask Q's on km's reading

I have heard 2 things about gps speed sensors,one is not legal no way ever which is what the VIRM states as well BUT i have spoken to 2 people who say they are legal as it is still a vehicle speed indicator, i am chasing a stand alone unit at the moment as one of our buses has speedo issues and the manufactorer is not interested in helping by sourcing a wiring diagram for me .BUT also this is a bus and runs a Hubo so vehicle milage is recorded that way.

all I can say is try it and see,and good luck

Ok cheers guys

Yea I thought about the odo - but really why is it that important. ? Guess its who u get the wof from ay

Does anyone know if u can get a gps speedo other than a gps for maps ??

I might have to source a s15 diff - then I need a s15 dash cluster as apparently the diff vss has a different signal to a gearbox vss - then I need to do some custom wiring to make the cluster work lol

Oh well got lots of time to sort this issue out

you can get a standalone speed metre pretty much all it has is a readout that has a GPS aerial in it and a couple of wires out of it ( earth,+ and maybe a engine on ) this is what I am chasing, they about $100 or so will let you know once the guy gets back to me.

the other way you could do it is by running a pickup of the driveshaft thru a converter box then to your speedo

That's exactly what I was thinking on the way to work - would have to be hall effect wouldn't it ? Would need some sort of adjustable out put to calibrate it to the Gauge

But anyway thanks heaps and I would love to know about the gps speedo

workshop lads have fitted these to ritchies buses http://www.bogaard.com.au/Products/DigitalSpeedos.aspx not sure which one but must be legal there rules are tight as and regular cofs.

site should tell you a bit.

i had a uniden gps radar detector that had speed on it too but got stolen.

BUT ya might be able to find on 2hand?

[johnny5]

yea that they are had mine for a while now

[Guest]

if you need to buy them for business be annoying waiting half a year for one to pop up lol. what about apexi rsm? i have no idea how they work.

think yo missing the point of me needing a digital speedo

running off a OBD port - utilising vehicle speed sensor

i dont have speed sensor - plus my car is obd 1 not obd 2

it needs to be GPS driven

looked up on ltsa - GPS is no good for a wof - the law states that the speedo needs to show forward moving speed at all times - GPS cannot gurantee this - as it wont work in tunnels etc -

looks like im either going to have to change diff and gauge cluster - or go back to a 5 speed
