Speedo out - V240, X240, V200, X200

Postby emute » Fri Oct 01, 2010 8:23 pm

As I was driving through the city this morning, just about every car was passing me. I'm no leadfoot, but I was sitting on the speed limit, so either everyone else in Adelaide was speeding today, or the v240's speedo is out a bit.

Is this a common issue with the v240?

To keep up with most of the other cars in the 60 zone, I was showing around 63 k's. Noticed the same situation in the 70, 80, 90 etc. zones. Doesn't really bother me if it is out a bit, but I just want to be sure rather than get slapped with a ticket.

Michael, this is pretty common with most new vehicles these days to be out a bit on the speedo's. I think anything upto 10% is considered normal, if it's out by quite a bit more it may be fault and need calibrating. My V240 is also out but I drive by ECU readout or GPS, if you have a GPS unit you may be able to use that to check and see what your actual speed is to see and work out.

Current ADR rules (introduced in 2006) wont allow any % of under reading (when your speedo reads a lower speed than your traveling) so most cars are made to slightly over-read (tell you your traveling faster than you are) by upto 4kph + 10%. So it's really just a matter of most companies "playing it safe". The other thing is any change in rolling diameter of your tyres from OEM specs will also affect speedo readings. If you don't have a GPS you can use to check your actual speed let me know and when your back around town we can catch up and check your speedo if you like.

Many things affect the actual speedo readings output so if your speedo was exactly correct at one point it could be incorrect as soon as the load changes or tyre pressure drops or increases, tyre wear etc.

We have a X240 and the speedo is out also
have to do about 67 to be on 60, at 100 we are only doing 93

My old mans Santa Fe has to do 110 on the speedo to do 100 on GPS.

I know the adr's so cant complain

We have an X240 and the speedo on that vehicle was out by 10%, also the odometer was out by 5%, so in fact I was racking up KM faster than I liked hence the warranty would run out before I actually did the 100,000km.

I raised this with Great Wall and like some have said if its within 10% that good enough.

The Mrs got sick and tired of remembering to do 110km in a 100km zone and 66km in a 60km zone, so I made some enquires and the local instrument/gauge shop in Canberra and they were able to fit a device which corrects the speedo/odometer error, this cost around $300 fitted.

This device is adjustable so if I change tyre profiles I can recorrect the speedo

I use a ScanGuage II on my Great Wall Ute for spedo read out amoungst other handy info being displayed, it's adjustable so can compensate for tyres etc. Also reads ECU fault codes and reads all other kinds of info from the ECU/sensors on the car. Think they are $200 or less and work a charm as another option/idea for folks finding this a issue.

Mitcon; I've seen your pictures and comments on Scanguage on another website; before you started this place..

Could you give a few details. e.g. for an X240; is it a simple "Plug and Play"? or is it a complex install; does it need specialist installers?

Regarding engine codes; are they available yet?

Any advice you could give re suppliers, installers, tricks and tips would be great.

Wayne piqued my interest with the ScanGauge too - particularly since it seems it just plugs in (somewhere).

From ScanGauge:

Most cars now have an On-Board-Diagnostic version 2 (OBD2 or OBD II) connector inside the passenger compartment.


I checked out their site and it seems they won't have any more in stock until later this month.

Wayne, I didn't see Great Wall on their compatibility list - did you just cross your fingers and hope for the best, or did you speak to someone at Ample Outdoors about it first?

I would really like to know what speed I'm actually doing.. and all the additional features look really interesting too.

It should be ok on a X240 as it is very much the same system as far as I know but I have not tried it. Install is super simple, you pulg the cable into your OBDII port and the other end into the Scangauge and thats it.
Setting up is fairly easy following screen promts and entering info like size of motor and fuel tank capacitiy, have a read on that website on features and use. It comes with some velro you just stick the gauge where you like, you can even pick the display colour light and how bright it is so you can see it easy at night.

I love mine, great way to keep instant trip info like current fuel use, avg use, speed etc..RPM, speedo, how much your fuel use was in cost, how much for the day in total, KTE features. And no when I got mine no-one knew if it would work or not with the GW, I just bought it but I had a fair idea it would work ;) . Some info on some cars you can't display but there is handy stuff you can set-up.

But if folks are just using it for speed only and you have a GPS unit maybe look in the settings/features in that as most of those will display speed.
Cheers

I mentioned on a thread yesterday about the Hillspeed Digital Speedometers and I have attached these 2 pictures. It is pretty much impossible to read them like this (too small :x ). If you may be interested, you can view them all the information about them on our website at http://www.bta4wd.com/category799_1.htm We have a couple of the GPS units in store at the moment. They are $198.00 each plus freight. They are accurate to within 2 km/h. Unforunately, I don't know of anyone else that is selling these.
