How accurate is your speedo

[viceroy]

Im pretty chuffed with mine

@ and indicated 124mph Im actually doing 122.24mph as indicated by a speed trap at the Gerotek testing facility

10% tolerance is allowed

not everyone has the ability to test their speedos without getting caught by a gatso or speed camera

 

[Swervin_Mervin]

10% out. When I was doing 40 indicated it came up as 36/37 on one of those speed message boards.

damn I wish I still had that photo of me with the gps unit, speedo said 60mph, GPS said 60.4mph

 

[Daz]

70 on my speedo, 73/74 on GPS..

[Tom]

Dont worry its not that easy to do anyway. (1.2 16v)

puttin bigger wheels on a car can put the speedo out as a bigger wheel acts as a bigger gear.depends on where the speedo takes its readin from

 

[viceroy]

In my case I reckon the 16" 205/45 could have made it more accurate...either that or it was spot on and is now 1.6% out

Mine shows 70 mph when actually doing 84.8 according to AP22!!!

So when it shows 105mph... should be 126!

id say mines spot on. i got gps display and a digi readout from the ecu projected onto my screen

 

[dbouwer]

Mine is spot on, with the 17"it closes the fault gap to .

 

[dbouwer]

Mine is spot on. With the 17" it closes the gap to about 0-1%.

 

[chris172]

my gps unit says mine is spot on!!

I look at mine more often when approaching cameras, and when it says 40 they dont flash so I guess it must be reasonably accurate.

 

[Essex_Lad]

mines out by bout 5%

i got a diddy steerin wheel so cant see my speedo properly so had to learn the MPH by the revs

13s = never tested

15s = 5th gear 3000RPM = 70MPH

17s = 5th gear 3000RPM = 67MPH

where can u get em recaliberated?
