Doesn't correcting the speedo throw off the odometer though. I know my speedo is off by around 5mph, according to my GPS.

That would be a good debate. GPS vs Speedo.
We all know the speedo is off, but, what makes the GPS the definitive speed reference?
I realize that the triangulation makes for a more efficient calculation but........
if GPS can only pinpoint to say 100yds? (not sure -probably more like ft, either way)
then that inaccuracy must also be figured into the speed. So any thoughts???

reviving an old thread because my new r3r seems to be off quite a bit. the mechanic at my dealer said triumphs margin of acceptable error is 30%

will tune ecu fix this? and since it is not cable driven will the odometer be knocked out of whack?

thanks,
Steve
 
Steve...I doubt that seriuosly that the speedometer could have up to a 30% difference that would be an "acceptable" error. Even Gold Wingers would wince at that one as that is often a big topic over on their forums.

For a Triumph "technician" to spout that off as "truth" would lead me to suspect anything else he says as being not quite up to par.

well i may have exagorated a bit. point was that triumph accepts some high percentage of inaccuracy with the speedo. my thinking is that when someone gets a ticket they wont be able to sue triumph about the speedo hehe.

back to my question. will tune ecu correct this? will it affect the odometer?
