To actually do 110kmph according to 3 different gpd units.. my speedo reads 119kmph....
My fuel economy sucks too... am hard pressed to break 11l per 100... and with the speedo out that makes it worse. Any thoughts... 2000k on the clock...I have a bullbar and roof rack with factory tyres and snorkel...
My speedo is out 4% at 100 Km, reading 104kph when GPS indicates 100kph. I would assume therefore the odometer trip or overall km would read 4% higher than actual, if of course the info is captured/processed by same mechanism. My wife’s elantra is 3kms out at 100km, and 4km out when tyres need replacing.Tasc4life wrote:ICKIS wrote:My speedo is out to the shithouse.... have used 3 different gps units in car and all read same speed... at 100km/hr on speedo i am only doing 92 or 3 kmph.... at 11o on the speedo am doing 103 on gps....

Is funny you mention the GPS thing, I actually Downloaded 2 of the apps and tested it on the way to work this afternoon.
Mine was pretty much on the money. At 60 kms speedo it was reading 58 kms on the GPS. I didn't test it long enough though. Will run it on the way up next trip.
That sucks about the high fuel economy, I can't really help out there. Have you tried different places for fuel at all? I'm sure somone here would know something to help out..
