I don't really have time to 'read the Internet'. My open questions: Did anyone record a maximum acceleration with the camera on the speedometer? Did anyone record a maximum acceleration with a 3-axis accelerometer? Did anyone record a maximum acceleration with a recording OBD? Agreed, this is a poor approximation for a dyno but it actually can provide some useful metrics. I did a little Google search for the 'blended power' metrics and the initial read suggests it is power measured at the tires. This makes a lot of sense and any of the above metrics along with the driver weight and fuel tank level a good enough, approximation. Thanks, Bob Wilson
