aniken I don't suffer from insanity; I enjoy every minute of it Donating Members 4,316 Member For: 21y 11m 24d Gender: Male Location: Sydney, south west Posted 25/08/05 12:49 PM Share Posted 25/08/05 12:49 PM No, not those speedos, the speedometer on the XR6 Turbo.On certain roads, such as the F6 freeway between Sydney and Wollongong, there are signs that warn you if you are close to or over the speed limit. Under normal conditions, they don't really do this until you go over 120 km/h. In the Turbo, I could drive at 120 km/h no problem and no warning lights. In the Focus, however, I can be doing 120 and there are warning lights all over the place. Is it possible that the speedos on the Turbo are calibrated to deliberately over-estimate your speed. Its similar in normal traffic too - in the T I could sit on 70 and cars are going past me, but in the Focus its the other way around.Anyone bothered to get theirs properly tested and calibrated? Was it out? Link to comment Share on other sites More sharing options...
ZAP No boost, no bottle, just my foot on the throttle! Lifetime Members 7,935 Member For: 20y 10m Gender: Male Location: Sydney Posted 25/08/05 01:04 PM Share Posted 25/08/05 01:04 PM I have the police speedo option and it is accurate +/-1km/h when used against my gps satnav.The indicated speed is always reading LOW, I think it is a requirement.This means when you are doing an indicated 70km/h the true speed is 67. This is what I have found anyway. Link to comment Share on other sites More sharing options...

I.e. setting the cruise control and resetting the average speed.Trent. Link to comment Share on other sites More sharing options...

Then push the reset on the trip computer it reads about 117. ......Ahh crap, they all beat me so I will edit my post to say that F6 sounds like a cool road...

Near the Albury/Wodonga border they have one of those speed readout signboards, myself and a bunch of other forumers went through there and compared speedo readings vs signboard and mine was one of the most accurate Link to comment Share on other sites More sharing options...

I have sat at 100 going past one of those speed check points and it said 96 Link to comment Share on other sites More sharing options...

Can you describe what it is please? Link to comment Share on other sites More sharing options...

So there would be a natural error. Link to comment Share on other sites More sharing options...
