digital speedo out

[db_notso]

Mine was, it's called putting 18" wheels when they're calibrated for 16".. @ 100kph i was doing 106kph.


As for this, In my dads SSV, it did the same thing, but the dial isn't facing you exactly, you need to move your head to the right a bit then it lines up.

DUH changing wheels in ve requires the ecm...i think to be reprogrammed to suit larger rolling diameter or is it ebcm? i dont remeber
someone from holden will know on here.................:hiding:

okay bud just syaing its true i used an exact equivelent of a radar gun.... and i calibrated it and checked againts an rpm generaotr its reading correctly cars arent!~

speedo's always will be out , you will have to check with a gps or something i guess

 

[db_notso]

dont trust gps
ever heard of lag on a connection?
a gps normally exhibits lag and inherintly stuffs up its accuracy greatly especially with your speed
ever noticed how one will say your speeding when your not? thats their lag

How did you confirm that?

Yup - two sat navs confirmed mine's spot on. Very surprising!

which would mean that one of them is inaccurate.
you dont want to know which one?

True yes, but more likely that both are inaccurate, one more so than the other.

But wait till you get some tyre wear and that will change, just the same as changing you tyre profile.
