The vehicle speed setting is what is utilized by the speedo and also as inaccurate. I have both set up on one of my data scan pages and it's a laugh seeing the difference between vehicle speed numbers and GPS speed.

I have vehicle speed and gps speed and see a very small difference between the two, at worst it would be 2 or 3km/h difference.
Where as comparing these to the physical speedomoter in the dash, it usually is at least 5km/h or more out.
Doesn't the
ECU DS utilise the abs speed sensor for the "vehicle speed"?
(might be applicable to wrx 08 onwards?!)
