  SPEEDO ACCURACY

  Hi All
  Been experimenting with the CCF settings (using an IID tool G4) to try and I prove the accuracy.
  the settings that are altered are as follows..
  MultiCAN-838 Speedo Market
  Market 0 (+3.5% +2km/h)
  Market 1 (+2%)
  You also have to have all these 3 setting to match
  MultiCAN - 838 Speedo Market. - set to Market 1
  MultiCAN - 577 SpdoCalPercentScale. - set to 1%
  MultiCAN -575 SpdoCalkmhOffset. - set to 0kph offset
  
  Improves the accuracy as measured against a GPS unit, but the true sped is one figure, there cruise control is +1mph and the speedo is showing +2 mph from the GPS unit.
  
  Has anyone had better results, and what settings?
  
  I should add I am running std 21" wheels with a 275x45 section tyre.
