Re: Speedo Accuracy...
I take it the Speedo is not Digital?
All analogue speedo's seem to be in accurate, I am not sure why all makes of car i have ever had or friends of had have all been in accurate. They tend ti under read up to 30 then after that they over read.
Dunno if it is to keep actual speeds down. So that drivers are going at there indcated say 70 mph when they are really only doing 67 mph. GPS is deffo more accurate than your standard speedo.
Can anyone explain how the speedo reading is produced is it direct from the gear box or something. That may explain it as the gear box should i think, spin quciker than what the wheels are doing. Maybe this produces the inaccuracy, as at ceratin speeds, the way the figure is produced is accurate but after a certain point it becomes increasinly in accurate after this point.
Does this make any sense as i am half asleep at my desk at work. [img]/ubbthreads/images/graemlins/sleep.gif[/img]
